AOD-9604 5 mg reconstitution calculator

Per-unit amounts in this vial are small enough to count in mcg. With 1 mL of water it’s 5 mg/mL and each unit holds 50 mcg; with 2 mL it’s 2.5 mg/mL (25 mcg per unit); with 2.5 mL it’s 2 mg/mL (20 mcg per unit). An easy slip with small vials is mixing up mg and mcg: 1 mg is 1,000 mcg, so the mix-up is a thousandfold error. Enter your prescribed amount in the unit your prescriber wrote it in, and let the calculator convert. The same water makes a 10 mg vial twice as strong, so units worked out for another vial size don’t carry over.

AOD-9604 is a synthetic fragment of human growth hormone, developed as an anti-obesity candidate. Tested as an oral drug in a 24-week study (n=534, 502 randomized), “it failed to demonstrate a significant benefit on the primary weight-loss endpoint”, and a 2026 review notes that this conclusion rests mainly on sponsor-reported outcomes rather than peer-reviewed randomized trials (Dominikowski et al., 2026). The reduced weight gain and body fat often quoted come from obese mice treated for 14 days (Heffernan et al., 2001; Heffernan et al., 2001). Claims about joints and tissue repair rest mainly on animal work too, according to the same review.

The FDA says compounded drugs containing AOD-9604 “may pose significant risk for immunogenicity for certain routes of administration” and may have “complexities with regard to peptide-related impurities and API characterization”. It has also “identified serious adverse events that may be associated with AOD-9604, though causality is not clear” (FDA). AOD-9604 is not in any category of the FDA’s 503A list updated May 14, 2026 (FDA). A 2026 review adds that products from unregulated supply chains carry “uncertainty surrounding product composition, dose” (Dominikowski et al., 2026). No regulator has checked the 5 mg on your label, and the calculator’s math is only as good as that number.

AOD-9604 is hGH(177–191) with an extra tyrosine at the start, which is why it is “sometimes labelled ‘hGH 176–191’ or just ‘GH fragment’” (Dominikowski et al., 2026). Whatever the name on your vial, the calculator works from the mg printed on it. For tested athletes, WADA’s 2026 Prohibited List bans “growth hormone fragments, e.g. AOD-9604 and hGH 176-191” at all times, in and out of competition (WADA).
