List of Peptides A to Z: Evidence, FDA and WADA Status

This list covers 71 peptides and related compounds. Only 11 have an FDA-approved product, and for 33 more no human trial turned up in PubMed, Europe PMC or ClinicalTrials.gov. Each row gives the compound, its human evidence, its US status and its WADA status.

The compounds are grouped by use so you can compare like with like. Where we have a full page on one, its name links to it.

How to read the tables. Approved or Phase 3 RCTs: randomized human evidence for the compound. Limited: small, uncontrolled, mixed or sponsor-linked human data. None: no human trial found. WADA: Named means the 2026 List writes the compound or its class out; S0 catch-all means any substance without regulatory approval.

Weight and metabolism peptides

The incretin drugs have the strongest human evidence on this page. Most of the small molecules and research peptides beside them have only mouse data.

Khavinson peptide bioregulators

Short peptides of 2 to 4 amino acids from Vladimir Khavinson’s group. Published work is in cells and animals, with one small human study. Brand-to-sequence mappings for Cardiogen, Cartalax and Ovagen appear only in reviews by the same group, so treat those names with care. See our Khavinson overview and bioregulator guide.

FDA approved, compounded or research only: what the labels mean

  • FDA approved. The agency approved a specific product for a specific use. 11 compounds here meet that test, each only for the uses shown in the tables.
  • Compounding lists. FDA keeps lists of bulk substances that pharmacies may be allowed to compound. Category 2 means FDA found significant safety risks. The withdrawn-nomination list holds substances whose nominators withdrew them from Category 2. Neither list approves a drug (13).
  • Advisory votes. In July 2026 FDA’s compounding advisory committee voted 8 to 6, with one abstention, to recommend BPC-157 and 7 to 4, with one abstention, to recommend epitalon for the 503A bulks list. Those votes are advisory, not decisions (29).
  • Research use only. This is a seller’s label. It doesn’t approve a compound, and it doesn’t make it safe for people.

Which of these compounds does WADA ban?

26 rows are named on the World Anti-Doping Agency’s 2026 Prohibited List, which applies in and out of competition unless stated. The classes are growth hormone releasing factors and secretagogues (S2.2.4), growth hormone fragments such as AOD-9604 (S2.2.3), testosterone-stimulating peptides in males such as hCG, GnRH agonists and kisspeptin (S2.2.1), IGF-1 and analogs, mechano growth factors and thymosin beta-4 derivatives (S2.3), myostatin-binding proteins such as follistatin (S4.3), and AMPK activators such as BAM15 and MOTS-c (S4.4.1) (63).

S0 also bans any pharmacological substance with no regulatory approval for human therapeutic use, and it names BPC-157. Tesofensine is a stimulant banned in competition. Athletes should check the full List and their anti-doping organization.

Common mix-ups this list corrects

  • Dihexa isn’t a hexapeptide. It’s a small-molecule peptidomimetic, and the 2014 paper behind its mechanism was retracted in 2025.
  • Orforglipron isn’t a peptide. It’s an oral small molecule that FDA approved on 1 April 2026.
  • CJC-1295 comes in two forms. The published human trials used the DAC form.
  • Sermorelin was an approved drug. FDA found it was not withdrawn for safety or effectiveness reasons.
  • Follistatin trials gave patients a gene by viral vector, not the injected protein sold online.
  • Melanotan I (Scenesse), melanotan II and PT-141 are three different compounds. Only two are approved, and neither is a tanning drug.
  • “Myostatin inhibitor” names a mechanism shared by proteins, antibodies and an unrelated SARM, not one peptide.

How to check a seller before you buy

Approval status tells you what’s legal. A certificate of analysis tells you what’s in one lot, and for a peptide it has to show identity as well as purity. Read our guide to verifying a peptide COA, compare sellers in best peptide vendors, and see peptide scams to avoid. For where to start, read what peptides are and the best peptides by goal.

Frequently asked questions

How many peptides are FDA approved?

Of the 71 compounds on this page, 11 have an FDA-approved product: Semaglutide, Tirzepatide, Orforglipron, Tesamorelin, SS-31 (elamipretide), GnRH (triptorelin), HCG, HMG (menotropins), PT-141 (bremelanotide), Melanotan I (afamelanotide), Oxytocin. Each is approved for specific uses only. The rest are unapproved.

Which peptides have the best human evidence?

The incretin drugs: semaglutide, tirzepatide, and in phase 3 trials retatrutide and CagriSema. In the largest trials they cut body weight by about 15% to 25% over 68 to 80 weeks. Tesamorelin has randomized trial support in HIV lipodystrophy.

Is BPC-157 approved?

No. The human evidence is three uncontrolled studies covering 30 people. FDA’s advisory committee voted 8 to 6 in July 2026 to recommend it for the compounding list, and that vote is advisory.

A research use only label doesn’t make a compound approved. Unapproved compounds sold for human use are regulated as unapproved drugs, and FDA limits what pharmacies may compound. This page isn’t legal advice, so check FDA’s compounding page and ask a pharmacist or clinician.

Which peptides are banned in sport?

26 of the compounds on this page are named on WADA’s 2026 Prohibited List, including growth hormone secretagogues, CJC-1295, tesamorelin, AOD-9604, IGF-1 and analogs, MGF, TB-500, follistatin, hCG, GnRH agonists and BPC-157. S0 bans any substance without regulatory approval.

Are all of these compounds peptides?

No. Some are small molecules, such as orforglipron, dihexa and 5-amino-1MQ. Others are proteins or mixtures, such as follistatin, IGF-1 LR3, hCG and menotropins. NAD+ is a coenzyme.

What are Khavinson peptide bioregulators?

They are short peptides of 2 to 4 amino acids from Vladimir Khavinson’s group, sold under names such as Pinealon and Vilon. Published work is in cells and animals, with one small human study.

How is the evidence on this page graded?

Each row reports the best human evidence found in PubMed, Europe PMC and ClinicalTrials.gov. Approval status comes from Drugs@FDA, DailyMed and FDA’s compounding page, and doping status from the 2026 WADA List.

This page is information, not medical advice. Talk to a clinician before using any compound listed here, especially with a cancer history or while pregnant.
