Is AOD-9604 FDA approved? Understand US product nonapproval, oral trial history, the 2024 compounding evaluation, and its specific 2026 WADA classification.
No, AOD-9604 is not FDA approved for human use in the United States. There is no FDA-approved AOD-9604 product for weight loss, fat loss, or any other indication, and the material sold under that name is either a research chemical or an unapproved compounded preparation. A peptide being studied in trials is not the same as a peptide the FDA has cleared for patients.
What Is AOD-9604?
AOD-9604 contains hGH residues 177-191 with an additional N-terminal tyrosine, making a modified 16-amino-acid peptide. The common name HGH fragment 176-191 should not be read as an unchanged native sequence.
The marketing pitch is that AOD-9604 can support lipolysis (fat breakdown) without raising IGF-1, changing blood sugar, or promoting growth. Most of that story comes from early laboratory and animal work rather than large human trials.
- Drug class: Growth hormone fragment (hGH 176-191 analog)
- Forms sold: Injectable vials, oral drops, sublingual tablets
- Claimed purpose: Fat loss and body composition change
- FDA status: Not approved for any human use
Is AOD-9604 FDA Approved? The Short Answer
AOD-9604 is not FDA-approved for human use in the United States. The FDA approves specific drug products — a defined molecule, made by a specific manufacturer, at a set dose, for a specific condition — after reviewing clinical and manufacturing data. AOD-9604 has never completed that process.
This page addresses US FDA product approval. A statement about another country's authorization needs that regulator's current record; US nonapproval alone does not establish every jurisdiction's status.
AOD-9604 has no FDA-approved human drug product. FDA's 2024 compounding evaluation did assess published and submitted evidence; evaluation is not marketing approval.
Why AOD-9604 Never Won FDA Approval
The larger oral obesity trial summarized in FDA's 2024 AOD-9604 evaluation enrolled 536 people and randomized 502 to placebo or 0.25, 0.5, or 1 mg daily for 24 weeks. It did not show a significant advantage on the primary weight-loss endpoint at 12 weeks. Oral trial arms are not human injection recommendations. The failure led to termination of the obesity development program; it should not be described simply as a small but established weight-loss effect.
FDA approval requires product-specific evidence of safety, effectiveness, and manufacturing quality. The reviewed AOD-9604 evidence did not establish such an approved product; it does not establish that no sponsor has conducted any work since.
Searches for is semaglutide fda-approved or is tirzepatide fda approved concern specific approved products and indications. Their approval cannot be transferred to a different compound or an unapproved combination.
How AOD-9604 Compares to Peptides With Real Approval
FDA approval is product-specific, so “approved” and “not approved” split the peptide world fairly cleanly. The table below shows where AOD-9604 sits next to better-known compounds.
| Compound or product | US FDA distinction | Scope |
|---|---|---|
| Semaglutide approved products | Approved for product-specific indications | Check the particular product label rather than assigning every indication to every brand |
| Tirzepatide approved products | Approved for product-specific indications | Check the particular product label |
| Bremelanotide / Vyleesi | Approved for a specific HSDD population | Not general sexual enhancement or all PT-141 products |
| AOD-9604 | No approved human drug product | No approved indication |
| CJC-1295 and ipamorelin | No FDA-approved products identified here | Do not infer approval from research-use sales |
| DSIP | No FDA-approved product identified here | Research listings are not approval |
| Elamipretide / Forzinity | FDA accelerated approval on September 19, 2025 | Improve muscle strength in adults and children with Barth syndrome weighing at least 30 kg |
Approval also gets narrower than most people expect. The same pattern shows up with is pt 141 fda approved for men, where the answer is no — bremelanotide is approved only for premenopausal women with hypoactive sexual desire disorder. Growth-hormone peptides follow that script too, which is why is cjc 1295/ipamorelin fda-approved returns a no as well.
How AOD-9604 Is Sold in the US
A research-use label is not a legal workaround that authorizes human treatment, and it does not establish pharmaceutical quality. A product's identity, content, microbial quality, and lawful intended use require their own verification.
Compounded drugs are not FDA-approved. The 2024 AOD-9604 evaluation raised quality, effectiveness, and safety concerns; it is not a blanket determination of every prescription, import, purchase, or possession question.
Most aod 9604 reviews posted online come from user forums and vendor pages rather than controlled studies, so treat them as anecdotes rather than evidence.
Safety, Side Effects, and Sports Bans
The review did not establish longer-term safety or a human subcutaneous safety profile. Oral and intravenous adverse-event findings should not be relabeled as generally mild injection findings.
The 2026 WADA Prohibited List names AOD-9604 among growth-hormone fragments in S2.2.3, prohibited at all times. It should not be classified here simply as an S0 non-approved substance. Anti-doping consequences and exemption decisions depend on applicable rules.
The Bottom Line on AOD-9604 and FDA Approval
AOD-9604 has no FDA-approved human drug product. Approval is product and indication specific: FDA's Forzinity record, for example, documents elamipretide approval for a narrow Barth-syndrome indication, not approval of all research-market SS-31 or other peptides.

Frequently Asked Questions
Is AOD-9604 FDA approved for weight loss?
No FDA-approved AOD-9604 human drug product or weight-loss indication exists. Its larger oral obesity trial failed the primary weight-loss endpoint and the obesity program was terminated; this should not be described as proven modest injection efficacy.
Is it legal to buy AOD-9604 in the United States?
No FDA-approved AOD-9604 human drug product exists. A research-use label does not authorize human treatment, and the applicable requirements for a particular product or practice should not be replaced by blanket buying, possession, import, or prescribing claims.
Is AOD-9604 banned in sports?
Yes. The 2026 WADA Prohibited List specifically names AOD-9604 in S2.2.3 among growth-hormone fragments, prohibited at all times. Applicable anti-doping rules, rather than a blanket statement here, determine consequences or any exemption decision.
