Overview
HGH 191AA is recombinant human growth hormone (191 amino acids). A 10 IU vial holds roughly 3.33 mg. Dosing is a weekly ramp from 200 mcg up to 900 mcg daily — bigger than most secretagogue protocols, because you’re replacing the real thing.
Preparation
Reconstitute a 10 IU (3.33 mg) vial with 3 mL of bacteriostatic water (BAC) for a ~1.11 mg/mL concentration. Roll gently to dissolve; refrigerate after mixing.
