A two-part synthetic peptide: one half homes to prohibitin, a protein on the lining of blood vessels that feed white fat, and the other half kills the cell it is delivered to. Starving fat tissue of its blood supply made obese animals lose fat quickly.
Evidence. Animal data only. In obese rhesus monkeys given daily injections for 4 weeks, body weight fell 7.4–14.7% and total body fat by about 39%, with dose-dependent kidney damage that mostly reversed within 28 days of stopping (2011). A first-in-human trial in men with metastatic prostate cancer and obesity opened in 2012, enrolled 4 of up to 15 planned patients and was terminated at the investigator’s request; no results were ever published or posted.
What it’s used for
None of these uses is approved. Uses tested in people come first, then claims that rest on animal studies or user reports.
Obesity
TrialNo published human result: the only trial, in men with metastatic prostate cancer and obesity, enrolled 4 of up to 15 planned patients and was terminated without reporting weight or safety.
Fat loss and belly fat
AnimalUnproven in people: in obese monkeys, 4 weeks of daily injections cut body weight 7.4–14.7% and total body fat about 39%, with kidney damage at the same dose.
Insulin resistance
AnimalUnproven in people: a measure of insulin resistance fell about 49% in treated obese monkeys while rising about 34% in untreated ones, and glucose tolerance improved in obese mice.
Type 2 diabetes
AnimalUnproven: in obese mice the effect on glucose tolerance appeared within days and held even when weight and food intake were matched. No human study exists.
Appetite suppression
AnimalNot what it was designed for, but treated monkeys ate less, and a 2012 letter argued this, not fat-vessel killing, explained the weight loss.
Trial: tested in people, with the result. Animal: cell or animal studies only.
Not approved as a drug in the US, the EU or anywhere else. Its first-in-human trial, run at a US cancer center from 2012, was terminated at the investigator’s request and closed out in January 2019; no later trial has been registered.
US compounding
Never nominated for pharmacy compounding, so it appears on none of FDA’s 503A or 503B bulk substance category lists (503A list updated May 14, 2026).
European Union
No marketing authorization; no adipotide product is approved anywhere, and its only trial was terminated.
United Kingdom
No marketing authorization (MHRA).
Canada
No marketing authorization (Health Canada).
Australia
No marketing authorization. Adipotide isn’t named in the Poisons Standard (October 2026).
Sport (WADA 2026)
Likely banned in sportNot named in the 2026 List and not covered by a named section. An unapproved compound whose development stopped falls under S0 non-approved substances, banned at all times.
Category 2 is FDA’s list of bulk substances that may present significant safety risks in compounding. The 503A bulks list adds substances that pharmacies may compound with. Advisory committee votes are advice; FDA makes the final decision. Sport status follows the WADA Prohibited List in force since January 1, 2026; athletes should confirm with their anti-doping organization. Checked October 5, 2026. Status outside the US checked October 7, 2026 against EMA, MHRA, Health Canada and TGA records. By country: EU, UK, Canada, Australia. Status of every compound.
How it works
Adipotide has two halves. The first, a nine-amino-acid loop, sticks to prohibitin, a protein found on the lining cells of blood vessels that feed white fat. The second is a short mirror-image sequence that breaks up the membranes of mitochondria, the cell’s power packs, and kills whatever cell it is carried into. In obese mice and monkeys, killing those vessel cells made white fat shrink, and blood sugar control improved.
AnimalMainly from cell and animal studies; not shown in people.
Not known
Why the fat is lost is disputed: treated monkeys ate less, and a letter in the same journal argued reduced food intake, not fat-vessel killing, explained the weight loss. Nothing about the mechanism has been shown in people.
Protocol
Trial
NCT01262664
0.03 mg per kg under the skin once daily for 28 days was the opening dose of a dose-finding trial in men with metastatic prostate cancer. It was stopped after 4 patients and no tolerated dose was ever established.
Community
No established dose exists. Figures quoted online disagree by more than tenfold and none comes from a human study. Monkey doses can’t be scaled to people, and the monkey kidney damage was dose-dependent.
Frequency
Not established
Route
Subcutaneous injection (the route used in monkeys and in the terminated human trial)
Cycle
No established cycle. The monkey studies and the human trial both ran 28 days of daily injections under medical supervision.

Taking it
Where it goes
Injection under the skin in both the monkey studies and the human trial, given daily by trial staff with blood and urine tests throughout.
If you miss a dose
No published guidance, and no established schedule to miss a dose from.
Body weight fell 7.4–14.7% against +1.0 to −3.5% in untreated monkeys; BMI fell 3.7–17.3%; waist measurement fell 6.5–14.3% in 9 of 10.
Animal
Through treatment and 4 weeks after, obese monkeys
Total body fat on DEXA scans fell by about 39% on average, against about 15% in the untreated group, and kept falling for 3 weeks after the last injection.
Animal
After 4 weeks, obese monkeys
A measure of insulin resistance fell by about 49% in treated monkeys while rising about 34% in the untreated group.
Animal
In people
Nothing is known. The only human trial was terminated after 4 patients and never reported weight, safety or anything else.
Trial
Side effects and what to do
Kidney tubule damage and rising creatinine (monkeys, dose-dependent above 0.25 mg per kg)
Also sugar and protein in the urine. Mostly reversed within 28 days of stopping. No human data; nobody is checking an unsupervised user’s kidneys.
Passing more urine and mild dehydration (monkeys, highest doses)
Seen alongside the kidney changes.
Eating less, possibly from nausea (monkeys)
The study authors couldn’t rule out mild nausea as part of the weight loss.
Unknown in people
Four patients received it in a trial that reported nothing, so human side effects and their rates are unknown.
Injection-site pain, redness or infection (unregulated vials)
Use sterile technique. Spreading redness, heat or pus needs medical care.
Stop and get medical help
Passing much less urine, swelling, confusion or breathlessness can mean kidney failure: stop and get medical help the same day. Hives with face or throat swelling or trouble breathing is an emergency.
Can it cause …?
The side effects people ask about most, answered one by one. Each answer says where it comes from.
Nausea or vomiting
AnimalNo human data. Monkeys ate less, and the authors couldn’t rule out mild nausea as part of the weight loss.
Diarrhea or constipation
No dataNo human data. One monkey developed a bowel blockage, which the vets judged unrelated to the compound.
Dizziness
AnimalNo human data. Monkeys on the highest doses passed more urine and became mildly dehydrated, which can cause lightheadedness.
Water retention or swelling
PrecautionNo data. Kidney injury of the kind seen in monkeys can cause fluid retention and swelling, which would be a reason to seek care.
Low or high blood sugar
AnimalNo human data. Blood sugar control improved in obese mice and monkeys; sugar also appeared in monkeys’ urine, a sign of kidney tubule damage.
Fast heartbeat or blood pressure changes
No dataNo human data: the one trial published nothing. Monkeys stayed alert and active at the doses studied.
More hunger
AnimalNo human data. Monkeys ate less during treatment, which one 2012 letter argued was the main reason they lost weight.
Liver strain
AnimalNo human data. Fat buildup in the liver was not seen in any monkey that received it.
Kidney problems
AnimalNo human data. In monkeys, creatinine rose and sugar, protein and tubule cells appeared in the urine, dose-dependently; most reversed 28 days after stopping.
Cancer risk
PrecautionUnknown. It kills cells it reaches, and its only human trial was in men with incurable prostate cancer and reported nothing. No cancer-risk study exists.
TirednessHeadacheTrouble sleepingHair lossAcne, rash or skin changesJoint or muscle painAnxiety, low mood or irritability
No dataNo human data: the one trial published nothing, so human side effects are unknown.
Precaution: a concern that follows from how it works or from a related drug, not measured. Animal: seen only in animal studies. No data: no human safety data. A side effect that hasn’t been reported can still happen, especially with long or high-dose use. Any of these across every compound: the side-effect finder.
Who should avoid it
No product label covers adipotide, so these come from human studies and from precautions based on how it works. Most important first.
Anyone with kidney disease
PrecautionThe kidney was the organ damaged in monkeys: creatinine rose, sugar and protein appeared in the urine and the tubules were injured, more so at higher doses.
Anyone taking drugs that strain the kidneys
PrecautionAdding a compound that injured monkey kidneys to drugs handled by the same organ has never been studied, in any species.
Pregnancy or breastfeeding
PrecautionNo human safety data exist, and the compound is designed to kill blood-vessel cells, which a pregnancy depends on.
Anyone with active or past cancer
PrecautionIts only human trial was in men with incurable prostate cancer and was stopped without reporting anything, so nothing is known about its effect on a cancer.
Anyone relying on product quality
PrecautionSold only as an unregulated research chemical. Nothing checks that a vial holds the right molecule, at the stated amount, free of contamination.
Interactions
No interaction studies have been published, and no product label lists any.
Precaution: follows from how it works or from a related drug, and hasn’t been tested. This isn’t a complete list: a pharmacist or doctor can check a specific medicine or condition. Every documented interaction, by medicine: drug interactions.
Special situations
What’s known about pregnancy, breastfeeding, kidney and liver problems, age and surgery. Where nothing has been studied, the row says so.
Pregnancy
PrecautionNo human data. It is designed to kill blood-vessel lining cells, which a developing pregnancy depends on, and no animal study has tested it in pregnancy.
Breastfeeding
PrecautionNo human data; it isn’t known whether it passes into breast milk.
Kidney problems
AnimalThe kidney took the damage in monkeys, dose-dependently, and a kidney enzyme is thought to break the molecule down. Nobody with kidney disease has been studied.
Liver problems
AnimalNot studied in liver disease. Liver fat buildup was not seen in treated monkeys.
Older adults
PrecautionNot studied in older people. The monkeys were 9–13 years old; the four trial patients were adults with advanced cancer and nothing was reported.
Children and teens
PrecautionNot studied in anyone under 18, and not approved for any age.
Surgery and anesthesia
PrecautionNo data. Kidney function and hydration matter for anesthesia; tell the surgical team about any injected compound.
Precaution: not studied, so the caution follows from how it works or from a related drug. Animal: from animal studies only. Ages are given as approved or studied; this site never gives doses for children. Across every compound: pregnancy, breastfeeding, kidney disease, liver disease, older adults and surgery.

Trials under way
Registered trials that are still running, or that finished without published results, most important first. Checked on ClinicalTrials.gov, October 7, 2026.
Phase 1NCT01262664
First-in-human dose-finding in men with metastatic prostate cancer and obesity, with weight change as a secondary measure
Terminated at the investigator’s request; 4 of up to 15 planned patients enrolled, closed out January 2019, no results posted
No human result has ever been published. The one trial enrolled 4 of up to 15 planned patients, all men with metastatic prostate cancer and obesity, and was terminated at the investigator’s request. Everything else is mice, rats and small groups of monkeys: 10 treated animals in the main 4-week study, with kidney damage at the effective dose and weight loss that may have come from eating less. Nothing is known about longer use, about healthy people, or about what is in an unregulated vial.
How it’s supplied
No vial size or dose has been established for Adipotide, so there’s no mixing math to show.
Sold as powder vials of unregulated research chemical. Strengths differ between sellers and nothing checks them. Vial Guide gives no mixing or dose figures: no tolerated human dose was ever established, and the dose that worked in monkeys also damaged their kidneys.

Storage before use
Freezer (−20 °C) for long-term storage, kept dry and dark.
After mixing or opening
Fridge (2–8 °C) once in solution. The monkey studies and the human trial used it dissolved in sterile saline.
Molecule: PubChem CID 163360068 (CAS 859216-15-2); sequence and design from Kolonin et al., Nat Med 2004 and Barnhart et al., Sci Transl Med 2011. No UNII is assigned (FDA Global Substance Registration System, searched October 8, 2026). The formula and weight are for the open-chain form with free thiols, as PubChem records it
Storage:Community Common research-chemical practice; no approved label exists for this peptide
Half the molecule is built from mirror-image (D) amino acids, so the body cannot easily break it down. The homing half is a loop closed between its two cysteines; PubChem records the open form. Nothing regulates identity, purity or sterility.
Cautions
Kidney injury was the main side effect in monkeys: rising creatinine, sugar and protein in the urine and damage to the kidney tubules, dose-dependent above 0.25 mg per kg. Most of it reversed within 28 days of stopping, with a trace left in one monkey per study.
Monkeys on the higher doses passed more urine and became mildly dehydrated.
The only human trial was stopped at the investigator’s request after 4 of up to 15 planned patients, and no safety or weight results were ever published.
Whether the fat loss comes from killing fat-tissue blood vessels or simply from eating less is disputed: the monkeys ate less, the authors couldn’t rule out mild nausea, and a 2012 letter in the same journal argued food intake was the real explanation.
Half of the molecule is built from mirror-image (D) amino acids, which the body cannot easily break down. The one enzyme known to handle them sits in the kidney, which may be why the kidney takes the damage.
Questions
What is adipotide?
A two-part synthetic peptide: one half homes to prohibitin, a protein on the lining of blood vessels that feed white fat, and the other half kills the cell it is delivered to. Starving fat tissue of its blood supply made obese animals lose fat quickly.
How does adipotide work?
Adipotide has two halves. The first, a nine-amino-acid loop, sticks to prohibitin, a protein found on the lining cells of blood vessels that feed white fat. The second is a short mirror-image sequence that breaks up the membranes of mitochondria, the cell’s power packs, and kills whatever cell it is carried into.

Why the fat is lost is disputed: treated monkeys ate less, and a letter in the same journal argued reduced food intake, not fat-vessel killing, explained the weight loss. Nothing about the mechanism has been shown in people.
Is adipotide FDA-approved?
Not approved as a drug in the US, the EU or anywhere else. Its first-in-human trial, run at a US cancer center from 2012, was terminated at the investigator’s request and closed out in January 2019; no later trial has been registered. Never nominated for pharmacy compounding, so it appears on none of FDA’s 503A or 503B bulk substance category lists (503A list updated May 14, 2026).
What is the usual adipotide dose?
From human studies (NCT01262664): 0.03 mg per kg under the skin once daily for 28 days was the opening dose of a dose-finding trial in men with metastatic prostate cancer. It was stopped after 4 patients and no tolerated dose was ever established. From community reports, not established: No established dose exists. Figures quoted online disagree by more than tenfold and none comes from a human study. Monkey doses can’t be scaled to people, and the monkey kidney damage was dose-dependent. These are the amounts sources reference, not recommendations.
Who should avoid adipotide?
No product label covers adipotide, so these come from human studies and from precautions based on how it works. Anyone with kidney disease: The kidney was the organ damaged in monkeys: creatinine rose, sugar and protein appeared in the urine and the tubules were injured, more so at higher doses. Anyone taking drugs that strain the kidneys: Adding a compound that injured monkey kidneys to drugs handled by the same organ has never been studied, in any species. Pregnancy or breastfeeding: No human safety data exist, and the compound is designed to kill blood-vessel cells, which a pregnancy depends on. The “Who should avoid it” section lists 2 more groups.
How should adipotide be stored?
Before mixing: Freezer (−20 °C) for long-term storage, kept dry and dark. After mixing: Fridge (2–8 °C) once in solution. The monkey studies and the human trial used it dissolved in sterile saline. This is common practice; no product label covers it.
Is adipotide banned in sport?
Probably. Not named in the 2026 List and not covered by a named section. An unapproved compound whose development stopped falls under S0 non-approved substances, banned at all times.
Has adipotide been studied in people?
No published human studies turned up in our October 2026 review. The evidence note at the top of this page sums up what is known.
How long has adipotide been studied in people?
Trial 28 days of daily injections, in monkeys and in the terminated 4-patient trial. No human result was published.
Does adipotide come in other forms, like a pill or nasal spray?
Animal Injection under the skin in every study and in the terminated trial. No oral, nasal or skin form has been tested, and the molecule is a peptide that the gut would break down.
Can you drink alcohol while taking adipotide?
Precaution No data. No study has looked at the two together; both alcohol and dehydration add to kidney strain.
Can adipotide be taken with semaglutide or tirzepatide?
Precaution No study has combined them. Both lower appetite and body weight in animals or people, so effects could add up, including on dehydration.
What happens if you take too much adipotide?
Animal No label and no human overdose data. In monkeys, single doses far above the studied dose weren’t fatal, but kidney injury was dose-dependent. Call Poison Help (1-800-222-1222), or emergency services for severe symptoms.
