AOD-9604 vs Tesamorelin
How AOD-9604 and Tesamorelin compare on research category, evidence tier, regulatory status, and reported side effects.
The verdict
These get grouped together in fat-loss discussion, but the evidence gap is large. Tesamorelin is FDA-approved (specifically for excess visceral fat in HIV-associated lipodystrophy) with real human trial data behind it. AOD-9604, a fragment of growth hormone, has mostly inconclusive human results and no FDA-approved weight-loss use. Going by what has actually been shown in people, Tesamorelin is far better supported; AOD-9604 remains largely unproven.
AOD-9604 is a fragment of HGH designed to target fat metabolism without the bulky GH side effects. Subtle compared to the GLP-1 drugs. Mostly used as a stack add-on during a cut, not as a primary fat-loss tool.
Tesamorelin is an FDA-approved GH-axis peptide that specifically targets visceral fat, the deep belly fat around organs. Daily injection. Slow burn, but the visceral fat reduction is well-documented.
Which one should you pick?
Pick AOD-9604 if users wanting localized fat-loss support or people who can't tolerate gh-class side effects (water, glucose impact).
Pick Tesamorelin if users targeting visceral (deep abdominal) fat specifically or older adults wanting gh-axis support without hgh.
