How to Reconstitute AOD-9604: A Step-by-Step Guide
Reconstituting AOD-9604 is not identical to reconstituting any other compound in this library. Water-soluble at ordinary working strengths.
Overview
Add bacteriostatic or sterile water slowly down the side of the vial and swirl gently. A 10 mg vial in 2 mL gives 5 mg/mL. Do not shake, and do not use any buffer containing a reducing agent.
What AOD-9604 actually is
AOD-9604 is a 16-part lab-made peptide copied from the very end of human growth hormone, with one extra building block (tyrosine) added at the front and a single sulfur-sulfur bridge holding it in a loop. Animal studies from the early 2000s looked at how it affects fat metabolism, and a later rabbit study looked at joint cartilage. It was developed in Australia as an obesity drug candidate, but that programme was stopped in 2007 and it was never approved as a medicine.
Supplied for laboratory research use only — not for human or animal use.

Diluent selection for AOD-9604
Water-soluble at ordinary working strengths. Two arginines give it a small net positive charge at neutral pH, which offsets the stretch of hydrophobic residues (Leu, Ile, Val, Phe). Avoid any diluent or buffer containing reducing agents such as DTT, TCEP or β-mercaptoethanol — they open the disulfide that defines the molecule.
Common reconstitution reference
A 10 mg vial in 2 mL yields 5 mg/mL. Keep the stock near neutral pH and free of reducing agents.

- Let the vial reach room temperature before opening.
- Add diluent gently down the vial wall and swirl; do not vortex.
- Keep reducing agents (DTT, TCEP, β-mercaptoethanol) and alkaline buffers away from the stock.
- Label aliquots with reconstitution date and diluent.
What AOD-9604 is studied for
Heffernan et al. (Endocrinology 2001) compared hGH and AOD9604 over 14 days in obese mice and in β3-adrenergic-receptor knockout mice. Both raised the repressed β3-AR expression in obese mice, but neither changed body weight or lipolysis in the knockout mice over the long-term protocol, leading the authors to conclude the lipolytic actions were not mediated directly through β3-AR.
Ng et al. (Horm Res 2000) studied oral administration of AOD9604 in obese Zucker rats, reporting reduced body-weight gain and increased adipose lipolytic activity, and — unlike intact hGH — no impairment of insulin sensitivity on euglycaemic clamp.
Stier et al. (J Endocrinol Metab 2013) pooled six randomised, double-blind, placebo-controlled trials and reported no change in serum IGF-1, no adverse effect on carbohydrate metabolism, and no anti-AOD9604 antibodies in tested participants. The same development programme did not show a clinically meaningful weight outcome.
Kwon and Park (Ann Clin Lab Sci 2015) gave intra-articular AOD9604, with or without hyaluronic acid, in a collagenase-induced knee osteoarthritis model in rabbits and scored cartilage morphology, histology and lameness.
