AOD-9604

AOD-9604 is a modified fragment (amino acids 177-191) of human growth hormone specifically designed to have fat-reducing effects without the broader metabolic impacts of full HGH. It stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) without affecting blood sugar or promoting tissue growth. This makes it one of the safest fat-loss peptides with a favorable side effect profile.

Dosing Protocol

500 mcg to 1 mg daily (50-100 units), injected subcutaneously. Doses can be split in half and done morning and evening. With standard reconstitution, 0.01 mg per unit — 50 units = 500 mcg, 100 units = 1 mg on a U-100 insulin syringe.

Reconstitution

Add 3 mL bacteriostatic water to a 3 mg vial, or 6 mL to a 6 mg vial.

Timing

Fasted before bed or upon waking (fasted cardio). Doses can be split in half and done morning and evening.
