GHRP-6 Dosage & Reconstitution

Growth hormone-releasing hexapeptide. 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: preclinical.

1Set Up Your Mix

0.8 mg/mL · 800 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.

0102030405060708090100 U-100 syringe · 1 mL · 100 units draw to 25
2 mg ÷ 2.5 mL = 0.8 mg/mL  →  200 mcg ÷ 0.8 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 10 doses.

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.
