AOD-9604 Side Effects

hGH fragment

AOD-9604's side-effect picture is unusual among research peptides because it actually has pooled human safety data. Across six randomized, placebo-controlled trials totaling roughly 900 subjects, its safety and tolerability were largely indistinguishable from placebo, with no change in IGF-1 or glucose tolerance and no anti-drug antibodies reported.[1][2]

Reported side effects

COMMONInjection-site irritation
LESS COMMONGenerally well tolerated in trials; few effects above placebo

That relatively reassuring safety signal should be read alongside the weak efficacy signal: the same program did not show meaningful weight loss, so a clean tolerability profile is not the same as a useful drug. Reported real-world effects are mostly local, such as injection-site irritation. Because AOD-9604 is sold as a research chemical or supplement ingredient rather than an approved medicine, product purity remains a practical concern, and it is prohibited in drug-tested sport.

Seek medical attention ifYou notice signs of an allergic reaction, or spreading redness at an injection site.

Managing side effects

The pooled human data suggests few effects beyond placebo, so the practical basics (site rotation, watching for signs of infection or an allergic reaction) cover most of it. Athletes should note its WADA-prohibited status before use.

FAQ

Is AOD-9604 safe?In pooled human trials its safety was largely indistinguishable from placebo, with no change in IGF-1 or glucose tolerance. That is a comparatively reassuring signal, though it comes without a matching efficacy benefit, and product quality is a concern with unregulated material.
Does AOD-9604 raise IGF-1 or blood sugar?The pooled human trial data reported no change in IGF-1 or glucose tolerance, distinguishing it from growth hormone itself on those measures.
