AOD-9604 Dosage & Reconstitution

hGH fragment 176-191. Work out exactly what to draw for your own mix, see the doses used in research, and follow a week-by-week plan. Evidence tier: clinical.

1Set Up Your Mix

2 mg/mL · 2000 mcg/mL
All answers assume a standard 1 mL U-100 syringe, where 1 unit = 0.01 mL. That is the usual insulin syringe and the one every number here is based on.

2 mg ÷ 1 mL = 2 mg/mL  →  500 mcg ÷ 2 mg/mL = 0.25 mL  →  × 100 = 25 units
Looks good. Draw to 25 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 4 doses.

Where this plan came from
Built from this peptide's dose range
Where this came from: Built from the doses listed for this peptide below — start at the lowest and step up, using the studies cited on this page. Nobody publishes a week-by-week plan for this peptide, so we built one: the doses are the researched ones shown below, and we simply put them in order from lowest to highest. Treat it as a starting point, not an official schedule.
