10 mg ÷ 3 mL = 3.333 mg/mL  →  250 mcg ÷ 3.333 mg/mL = 0.075 mL  →  × 100 = 7.5 units
Looks good. Draw to 7.5 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 40 doses.

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.
