5 mg ÷ 3 mL = 1.667 mg/mL  →  200 mcg ÷ 1.667 mg/mL = 0.12 mL  →  × 100 = 12 units
Looks good. Draw to 12 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 25 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.

Also known as
Body Protection Compound 157, PL 14736
Class
Tissue Repair & Recovery
Route
Subcutaneous
Half-life
~4 h (preclinical)
Evidence tier
Preclinical

A pentadecapeptide fragment derived from a sequence in human gastric juice. The published record is almost entirely preclinical research on tendon, ligament, muscle and gastrointestinal healing. There is no completed, published human efficacy trial, and reported doses are extrapolations from weight-based research figures rather than clinically established ranges.
