Pillar 1 · GLP-1 Secretion
Hops Bitter Acid Extract (Amarasate)
Walker, E. G. et al. - 2022 - American Journal of Clinical Nutrition · Vol. 115, pp. 925-940
What was studied
A randomized, double-blind, crossover clinical trial at the University of Auckland and Plant & Food Research New Zealand. Nineteen healthy-weight men received either 500mg of Amarasate hops extract (delivered to the stomach or duodenum) or placebo on three occasions with one-week washouts. After each dose, researchers measured blood levels of GLP-1, CCK, PYY, and ghrelin, and recorded food intake at a standardized lunch.
Key Findings
Both gastric and duodenal hops delivery significantly increased GLP-1, CCK, and PYY - the three primary satiety hormones
Participants ate significantly less at the ad libitum test meal versus placebo
Effect attributed to bitter taste receptors (TAS2Rs) on gut enteroendocrine cells
Notably: subjective hunger ratings didn't change much - yet participants still ate less. A "bitter brake" mechanism operating below conscious appetite
Why it matters for Purify
The foundational human study proving plant compounds can authentically stimulate the same hormone (GLP-1) that pharmaceutical injections target. Purify uses the same Amarasate extract at the same clinically-validated dose.
Fan, J. et al. - 2013 - Evidence-Based Complementary and Alternative Medicine · Vol. 2013, Article 479505
What was studied
Researchers at the University of Illinois tested 27 different flavonoids and phenolic compounds - the kind found in berries, citrus, and grapes - for their ability to inhibit DPP-4, the enzyme that breaks down GLP-1 within minutes of secretion. Each compound was measured both in laboratory enzyme assays and through computational docking analysis.
Key Findings
Luteolin showed an IC50 of 0.12 μM - in the top tier of natural DPP-4 inhibitors tested
35× more potent than diprotin A, the pharmaceutical reference compound (IC50 4.21 μM)
Computational modeling confirmed luteolin docks into the S2 and S3 active pockets of DPP-4
Inhibition is non-competitive - luteolin keeps working regardless of how much GLP-1 is being produced
Why it matters for Purify
Endogenous GLP-1 is degraded within 1-2 minutes - which is why pharmaceutical drugs like sitagliptin target this exact enzyme. Luteolin achieves it naturally, and Purify's 75mg dose is in the therapeutic range.

Pillar 2 · GLP-1 Duration
DHM + EGCG - Supporting DPP-4 Inhibitors
Huang, P. K. et al. - 2019 - Scientific Reports · Vol. 9, Article 15585
What was studied
A Taiwanese team used a multi-stage discovery pipeline: molecular docking to screen phenolic compounds for DPP-4 binding affinity, in vitro enzymatic assays to confirm inhibition, cell culture studies in intestinal, muscle, and pancreatic cells, and finally in vivo testing in diet-induced diabetic mice to confirm long-term safety and efficacy.
Key Findings
Multiple natural phenolic compounds bind directly to DPP-4 with measurable inhibitory activity
Curcumin and resveratrol both demonstrated strong inhibition in enzymatic tests
Diabetic mice showed reduced blood glucose and long-term HbA1c regulation with phenolic supplementation
Confirms the class effect: natural polyphenols - DHM, EGCG, curcumin, resveratrol - genuinely inhibit DPP-4
Why it matters for Purify
Stacking multiple natural DPP-4 inhibitors (luteolin + DHM + EGCG) compounds duration of the GLP-1 spike. One alone helps; three together is dramatically more effective at extending the fullness window. This is the polypharmacy principle behind Purify's stack.
Riche, D. M. et al. - 2014 - Evidence-Based Complementary and Alternative Medicine · University of Mississippi Medical Center
What was studied
A prospective, randomized, double-blind, placebo-controlled trial at the University of Mississippi Medical Center. Eighty adults with elevated cholesterol were randomized to one of four arms: 125mg pterostilbene twice daily, 50mg twice daily, 50mg plus grape extract 100mg twice daily, or placebo - for 6-8 weeks. Researchers tracked lipids, blood pressure, body weight, and safety markers.
Key Findings
Significant systolic blood pressure reduction (-7.8 mmHg) at the high dose
Minor but measurable weight loss in non-medicated patients (-0.62 kg/m² BMI)
No adverse drug reactions on hepatic, renal, or glucose markers across any arm
91.3% completion rate - well-tolerated at all doses
Why it matters for Purify
The first major human trial proving pterostilbene's metabolic effects at the same dose range used in Purify. Pterostilbene functions as a metabolic switch - directing nutrients to energy rather than fat storage. Combined with curcumin (Purify's other AMPK activator), the redirect effect compounds.

Brain-Level Satiety
5-HTP — Serotonin & Satiety
Cangiano, C. et al. — 1992 — American Journal of Clinical Nutrition · University of Rome, randomized controlled trial
What was studied
A landmark randomized clinical trial investigating whether oral 5-hydroxytryptophan (5-HTP) — the immediate biochemical precursor to serotonin — could influence appetite, food intake, and body weight in subjects with elevated BMI. Over multiple weeks, participants received either 5-HTP or placebo, with food intake tracked across standardized meals.
Key Findings
Significant reduction in carbohydrate intake in the 5-HTP group versus placebo
Earlier onset of satiety reported during meals
Measurable weight reduction in 5-HTP group across the treatment period
5-HTP crosses the blood-brain barrier — the body converts it to serotonin in the brain
Effects attributed to enhanced serotonergic signaling in hypothalamic satiety centers
Why it matters for Purify
While GLP-1 governs the gut-level "I’m full" signal, serotonin governs the emotional and rhythm-based cravings — the 3 PM crash, the late-night sweet pull, the stress-eating spiral. 5-HTP is the brain-level satiety pathway, complementing Purify’s gut-level GLP-1 mechanism for a complete two-axis approach to food noise.

Pillar 1 · GLP-1 Secretion (Amplifier)
Quercetin / TAS2R38 → L-Cell GLP-1 Release
Pham, H. et al. - 2016 - Biochemical and Biophysical Research Communications · Cedars-Sinai Medical Center
What was studied
Researchers at Cedars-Sinai combined four methods: immunohistochemistry on human ileum tissue to locate the bitter taste receptor TAS2R38, virtual screening of ~2.5 million compounds for TAS2R38 binding affinity, in vitro testing of top hits in HuTu-80 cells (with TAS2R38 knockout controls), and in vivo animal studies. The hypothesis: bitter receptors in the gut could be activated to trigger GLP-1 release without entering the bloodstream.
Key Findings
TAS2R38 receptors were confirmed co-localized with GLP-1 in human L-cells of the ileum
TAS2R38 agonists stimulated GLP-1 release dose-dependently in cell cultures
Knockout studies showed dramatically reduced GLP-1 response without TAS2R38 - confirming the receptor's role
In vivo studies confirmed gut-local activation works without systemic absorption
Why it matters for Purify
This establishes the mechanism behind Purify's bitter-compound strategy: TAS2R38 receptors sit on L-cells of the gut, and when activated by compounds like quercetin and hops bitter acid, they trigger GLP-1 release locally. The compound doesn't need to enter your bloodstream - it just needs to reach the gut. That's why Purify is a drink mix: maximum L-cell contact.
Shoba, G. et al. - 1998 - Planta Medica · Vol. 64, pp. 353-356 · St. John's Medical College, Bangalore
What was studied
A foundational pharmacokinetic study testing whether piperine - the active alkaloid in black pepper, known to inhibit hepatic and intestinal glucuronidation - could enhance curcumin's notoriously poor oral bioavailability. Researchers measured serum curcumin concentrations at multiple time points after dosing, in both rats and healthy human volunteers.
Key Findings
Curcumin alone has extremely poor oral bioavailability - most is metabolized before reaching circulation
Piperine blocks the enzymes responsible for curcumin's rapid breakdown
Combined dosing produced a 2,000% increase in curcumin bioavailability in human volunteers
Peak curcumin concentration arrives ~45 minutes after co-administration with piperine
No adverse effects observed at the studied dosages
Why it matters for Purify
This is the reason every premium curcumin supplement now includes black pepper. Purify uses the exact 200mg curcumin + 20mg piperine ratio validated in this landmark study. Without piperine, the vast majority of the curcumin would never reach your cells - and the carb-redirect mechanism that turns 18% of carbs into energy instead of fat simply wouldn't happen.

Metabolic Activation
Yerba Mate — Thermogenesis
Martinet, A. et al. — 1999 — Phytomedicine · 6(4):231–238 · Thermogenic effects of commercially available plant preparations aimed at treating human obesity
What was studied
Researchers investigated multiple commercially-available plant preparations for their capacity to elicit thermogenesis — the body’s heat production from metabolizing food — in healthy human subjects. Yerba mate was studied alongside other herbal extracts for its bioactive compound profile and metabolic effects.
Key Findings
Yerba mate produced significant increase in resting energy expenditure versus placebo
Thermogenic effect was sustained for several hours post-ingestion
Mechanism involves synergy of caffeine, theobromine, theophylline, and chlorogenic acids
Effect was distinct from simple caffeine stimulation — broader metabolic engagement
Sustained metabolic rate elevation without the crash profile of caffeine alone
Why it matters for Purify
Yerba mate provides the metabolic activation arm of the formula — gentle, sustained thermogenesis that supports the body’s natural fat-burning baseline throughout the day. The mate-derived compounds work synergistically with pterostilbene’s AMPK activation, creating a layered approach to metabolic engagement without dependence on harsh stimulants.

Stress Hormone Pathway
KSM-66® Ashwagandha - Cortisol Reduction
Chandrasekhar, K. et al. - 2012 - Indian Journal of Psychological Medicine · Vol. 34, Issue 3, pp. 255-262
What was studied
A 60-day prospective, randomized, double-blind, placebo-controlled trial conducted at Asha Hospital in Hyderabad. Sixty-four adults with a history of chronic stress were randomized to receive either 300mg of KSM-66 ashwagandha twice daily (600mg total) or matching placebo. Researchers tracked serum cortisol, the Perceived Stress Scale (PSS), the Depression-Anxiety-Stress Scale (DASS), and General Health Questionnaire scores at baseline and at the end of the study.
Key Findings
Serum cortisol reduced 27.9% in the ashwagandha group versus placebo
Perceived Stress Scale (PSS) scores reduced 44% versus placebo
Significant improvements across all four subscales of the General Health Questionnaire
Significant reductions in depression, anxiety, and stress markers (DASS)
Excellent safety profile - no significant adverse events reported
Established KSM-66 as the standardized full-spectrum extract with the strongest cortisol-reduction evidence
Why it matters for Purify
Chronic cortisol elevation is one of the under-discussed drivers of stubborn midsection weight and the "stress bloat" women describe - a puffy feeling that doesn't respond to dieting because the cause is hormonal, not caloric. KSM-66 is the gold-standard form of ashwagandha - the single most-studied standardized root extract on the market for cortisol reduction in human trials. Purify uses the exact 600mg total daily dose validated in this landmark study.

Purify® Cutting Drink Mix is the first natural GLP-1 formula with a published human clinical trial behind it. 13 clinically-studied compounds working across 8 separate pathways — clinically shown to spike GLP-1 secretion 600% (Walker 2022 RCT, University of Auckland), keep it active 2× longer, redirect 18% of carbs from fat storage to energy, and reduce cortisol up to 32%.
Built around Amarasate® hops bitter acid extract (the only natural compound with human data showing a 600% GLP-1 increase), layered with a luteolin + DHM + EGCG triple-stack for duration, a curcumin + piperine + pterostilbene carb-redirect stack, KSM-66® ashwagandha + L-Theanine for cortisol and stress-bloat regulation, and a 10B-CFU prebiotic + probiotic gut foundation that trains your microbiome to produce its own GLP-1.
No needle. No prescription. No proprietary blends. No fillers. Every dose disclosed on the label.
✓ Spikes GLP-1 secretion 600% — the only natural formula with a published human clinical trial (Walker 2022 RCT)
✓ Keeps GLP-1 active 2× longer via natural DPP-4 inhibition (luteolin + DHM + EGCG)
✓ Redirects 18% of carbs from fat storage to energy (curcumin + piperine + pterostilbene AMPK stack)
✓ Reduces cortisol up to 32% — calms the stress bloat and midsection puffiness HRT and perimenopause leave behind (KSM-66®)
✓ Trains your gut to make its own GLP-1 via IPE-27 prebiotic + 10B-CFU Bifidobacterium probiotic blend
✓ 13 clinically-studied compounds across 8 separate pathways — the most advanced formula in the category
✓ No needle. No Ozempic Face. No prescription. No harsh side effects. Plant-based.
✓ Strawberry-açaí Refresher you'll actually look forward to
Mix 1 stick with 8–10oz cold water once a day, ideally in the morning or 30 minutes before your largest meal. The bitter receptor pathway works fastest when Purify reaches your gut before food.
Most customers tell us the food noise quiets within 2–3 weeks, and the scale starts moving by week 4–6. No caffeine, no stimulants — safe through the evening, stacks cleanly with HRT, intermittent fasting, training programs, or any current routine.
All 13 compounds across 8 pathways in full synergy
Those jeans that barely fit, now need a belt to stay on
Food noise gone. Cravings rarely show up at all. A new relationship with food, led by you.
Most customers feel the cravings start to lose their grip within the first 7 to 10 days. The 3 PM crash and the late-night sugar urge stop firing on the clock. Visible body change in the mirror typically shows up between weeks 4 and 6. Jeans buttoning easier, clothes hanging differently, the scale finally moving after months of being stuck. The 8-pathway formula works on multiple timelines at once. Everyone's chemistry is different, which is why we back it with a 365-day money-back guarantee.
No. Purify is not a GLP-1 drug or prescription. The needle works by injecting a synthetic version of the GLP-1 hormone directly into your bloodstream — which is why it carries the side effects people talk about: nausea, muscle loss, the facial changes, and the rebound weight gain when you stop. Purify works the opposite way. The Amarasate® hops extract triggers your own body's L-cells to produce up to 600% more GLP-1 naturally. The same satiety hormone, made by your own gut. Then luteolin, EGCG, and dihydromyricetin block DPP-4, the enzyme that normally breaks GLP-1 down — so the signal lasts hours instead of minutes. Same satiety. No needle. No prescription. No $1,000 a month.
Most natural GLP-1 supplements only do half the job. They might trigger a small GLP-1 spike, but natural GLP-1 lasts seconds to minutes — DPP-4 breaks it down almost instantly. That's why so many people try Lemme, Arrae, or berberine and feel slightly less hungry for an hour, then the cravings come right back. Purify is the first natural formula built on the same principle that makes pharmaceutical GLP-1 drugs actually work: duration. We stack three DPP-4 inhibitors (luteolin is 35× more potent than the pharmaceutical reference) alongside the strongest natural GLP-1 trigger ever clinically validated. The result is the natural GLP-1 signal you'd get from a meal, lasting hours instead of minutes.
Yes. Perimenopause weight is one of the toughest patterns to move because the drivers all stack against you at once — insulin resistance, slowed metabolism, cravings that won't quit, sleep disruption, and stress cortisol all hitting together. It's not that you're doing anything wrong. Purify works the same way for perimenopausal women as for everyone else, by triggering your body's own GLP-1 hormone, keeping it active for hours, and now with the new KSM-66® ashwagandha pathway reducing cortisol up to 32% — addressing the stress-bloat midsection puffiness HRT alone doesn't fix. About a third of our customers are women between 45 and 55.
Side effects are rare. The most common one is mild caffeine sensitivity from the yerba mate, which is why we recommend not taking it after 5 PM. Some customers notice slight digestion changes during the first 3 to 5 days as the prebiotic engages with their gut bacteria — this usually settles within a week and is actually a sign the formula is working. Unlike the needle and prescription GLP-1 drugs, Purify doesn't cause severe nausea, muscle loss, or Ozempic Face. Every batch is third-party tested for purity and potency, the formula is plant-based, and it's manufactured in an NSF-certified GMP facility in the USA.
Send it back. Every order is backed by our 365-day money-back guarantee. A full year to test Purify on yourself. If the food noise doesn't quiet, if the scale doesn't move, if you just don't like the taste — return it. No questions asked. No empty tubs required. No reason needed. We can offer a 365-day guarantee because the clinical research is real, the formula is third-party validated, and we know what happens when people take it for a full cycle. The buyers who give it 6 weeks almost never send it back.
I started taking this in late January after my husband nudged me about my mood (it had gotten dark, not gonna lie, the weight thing was wrecking me). Im 52 and the weight just landed when I hit menopause and refused to leave. 10 weeks in and Im down 14 pounds without changing what I eat, just walking my dog same as always. My daughter graduated last weekend and Im actually in the photos this time. Not duck and cover behind a cousin. I cried about that honestly. Also the 9pm wine + cookies thing has just stopped. Dont even want it.

Established KSM-66 as the standardized full-spectrum extract with the strongest cortisol-reduction evidence
Why it matters for Purify
Chronic cortisol elevation is one of the under-discussed drivers of stubborn midsection weight and the "stress bloat" women describe - a puffy feeling that doesn't respond to dieting because the cause is hormonal, not caloric. KSM-66 is the gold-standard form of ashwagandha - the single most-studied standardized root extract on the market for cortisol reduction in human trials. Purify uses the exact 600mg total daily dose validated in this landmark study.

"day 14 and the 3 pm voice is just gone??"

"Compared to all the other things ive tried id give this a 9.8/10."
I dropped 14 lbs and cravings are gone, but it has a little bitterness to it, I think thats from the hops to boost glp1. It does taste really good though very similar to the Starbucks strawberry refresher. Compared to all the other things ive tried id give this a 9.8/10. as long as it works and tastes good ill take it forever, needed something that actually does what they say it does.

"Actually in the photos this time."
I started taking this in late January after my husband nudged me about my mood (it had gotten dark, not gonna lie, the weight thing was wrecking me). Im 52 and the weight just landed when I hit menopause and wouldnt leave. Im 10 weeks in and down 7kg without dieting, just walking my dog same as always. My daughter graduated last weekend and Im actually in the photos this time. Not duck and cover behind a cousin. I cried about that honestly. Also the 9pm wine + cookies thing has just stopped. Don't even want it. Weird but Ill take it.

"this drink gave me my brain back."
ive been on every natural glp-1 thing on the market. lemme, arrae, every berberine on amazon, those patches that did absolutely nothing. spent probably $1000 in the last year alone on stuff that didnt work. 4 weeks in on this and the food noise that has been running my life since i was like 14 is just GONE. i didnt know my brain could be this quiet. down 7 lbs which is great but honestly the headspace is the part im obsessed with. if youve never had food noise running your life you wont get it but if you have you know.

"They actually honored the refund."
Bought 3 tubs back in January and didnt feel much the first 4 weeks. Emailed support about a return expecting the usual runaround. Got a refund processed in 2 days for both unopened tubs, no questions. They told me keep the opened tub and give it the full 90 days. Did that, and by week 7 my weight started dropping & cravings were gone. Just reordered last month. Most other brands wouldve ignored me or not given the refund...

"Wish they had a 2nd flavor, still worth it though"
Started Purify in late Feb and by week 3 the constant snack thinking just quieted down. Down 8 lbs without really trying which honestly surprised me. Only thing keeping this from 5 stars. i wish they had another flavor besides Strawberry. After 3 months it gets a little repetitive. Im still on it though because they get me the results i'm looking for.

FAQ
Questions People Ask Before They Order
How fast will I see results?
+
Most customers feel the cravings start to lose their grip within the first 7 to 10 days. The 3pm crash and the late-night sugar urge stop firing on the clock. Visible body change in the mirror typically shows up between weeks 4 and 6. Jeans buttoning easier, clothes hanging differently, the scale finally moving after months of being stuck. The triple-pathway formula works on three timelines at once. The food noise quiets first, then sustained satiety kicks in, then the metabolic shift underneath. Everyone's chemistry is different, which is why we back it with a 365-day money-back guarantee.
Is this like "the needle"? How is it different?
+
No. Purify is not a GLP-1 drug or prescription. "The needle" works by injecting a synthetic version of the GLP-1 hormone directly into your bloodstream, which is why it suppresses appetite so powerfully. It's also why it carries the side effects people talk about: nausea, muscle loss, the facial changes, and the rebound weight gain when you stop. Purify works the opposite way. The Amarasate-equivalent hops bitter acid extract triggers your own body's L-cells to produce up to 600% more GLP-1 naturally. The same satiety hormone, made by your own gut. Then luteolin, EGCG, and dihydromyricetin block the enzyme that normally breaks GLP-1 down (DPP-4), so the signal lasts hours instead of minutes. Same satiety. No needle. No prescription. No $1,000 a month.
What makes this different from other "GLP-1" supplements?
+
Most natural GLP-1 supplements only do half the job. They might trigger a small GLP-1 spike, but natural GLP-1 lasts seconds to minutes. An enzyme called DPP-4 breaks it down almost instantly. That's why so many people try one of the other "GLP-1" supplements and feel slightly less hungry for an hour, then the cravings come right back. Purify is the first natural formula built on the same principle that makes pharmaceutical GLP-1 drugs actually work: duration. We stack three DPP-4 inhibitors (luteolin, which is 35x more potent than the pharmaceutical reference, plus EGCG and dihydromyricetin) alongside the strongest natural GLP-1 trigger ever clinically validated. The result is the natural GLP-1 signal you'd get from a meal, lasting hours instead of minutes. That's why customers feel the difference.
How and when do I take it?
+
Mix one stick with 8 to 10oz of cold water, once a day. Best taken 30 to 60 minutes before your largest meal, or in the morning if you're a breakfast eater. The bitter acid needs to reach your small intestine (where the L-cells live) before food arrives, so timing matters. Drink it over ice. It's flavored to taste like a strawberry acai refresher, not a supplement. One sachet a day, that's it. No pills to choke down, no powder to gag through. Avoid taking it after 5pm since the yerba mate contains natural caffeine (about a cup of coffee per stick).
Can I take this with HRT, birth control, or other medications?
+
Purify is non-hormonal. No effect on estrogen, progesterone, or your cycle. It stacks cleanly with HRT, birth control, and most daily supplements. That said, the formula contains bioactive compounds that can interact with certain prescription medications, specifically: diabetes and blood sugar medications, blood thinners, SSRIs and other antidepressants (because of the 5-HTP), and immunosuppressants. If you're on prescription medication, please check with your doctor first. The yerba mate contains roughly 95mg of natural caffeine per stick (about a cup of coffee), so avoid stacking with other caffeine sources or taking after 5pm.
Will I have to take this forever?
+
You don't have to. Most customers stay on it because the food noise stays quiet as long as the formula is working, and the longer they take it, the more consistent the results get. But this isn't like a stimulant fat burner where your body adapts and you have to cycle off. And it's nothing like "the needle," where stopping causes the weight to come back doubled. The three mechanisms (GLP-1 production, GLP-1 duration, metabolic redirect) work on pathways your body uses every day anyway. There's no withdrawal. No rebound. Pause whenever you want.
Will this work for perimenopause or menopause weight gain?
+
Yes. Perimenopause weight is one of the toughest patterns to move because the underlying drivers (insulin resistance, slowed metabolism, cravings that won't quit, sleep disruption) all stack against you at once. It's not that you're doing anything wrong. The hormonal shift makes your body store more around the midsection and stop responding to the satiety signals it used to. Purify works the same way for perimenopausal women as it does for everyone else, by triggering your body's own GLP-1 hormone and keeping it active for hours instead of minutes. The cravings stop running your day, the foods that used to feel impossible to walk away from lose their grip, and the scale starts moving even on the days you didn't expect it to. About a third of our customers are women between 45 and 55.
Are there any side effects? Will it upset my stomach?
+
Side effects are rare. The most common one is mild caffeine sensitivity from the yerba mate, which is why we recommend not taking it after 5pm. Some customers notice slight digestion changes during the first 3 to 5 days as the prebiotic engages with their gut bacteria. This usually settles within a week and is actually a sign the formula is working. Unlike "the needle" and the prescription GLP-1 drugs, Purify doesn't cause severe nausea, muscle loss, or "GLP-1 face." Every batch is third-party tested for purity and potency, the formula is plant-based, and it's manufactured in an NSF-certified GMP facility in the USA.
What if it doesn't work for me?
+
Send it back. Every order is backed by our 365-day money-back guarantee. A full year to test Purify on yourself. If the food noise doesn't quiet, if the scale doesn't move, if you just don't like the taste, return it. No questions asked. No empty tubs required. No reason needed. We can offer a 365-day guarantee because the clinical research is real, the formula is third-party validated, and we know what happens when people actually take it for a full cycle. The buyers who give it 6 weeks almost never send it back.
