AOD-9604

Human clinical Weight Loss & Metabolism In 2 protocols 3 sources

AOD-9604 is a modified fragment of human growth hormone (HGH) that includes amino acids 177-191. Research indicates it mimics the fat-burning effects of HGH by stimulating lipolysis and inhibiting lipogenesis, without the adverse effects on blood sugar or tissue growth typically associated with full-length HGH.

01Dosing reference

02Mechanism of action

01

Receptor Binding

AOD-9604 binds to specific receptors on fat cells, mimicking the lipolytic domain of human growth hormone.

02

Lipolysis Stimulation

It triggers the breakdown of stored fat (lipolysis) and inhibits the formation of new fat cells (lipogenesis).

03

Metabolic Regulation

Unlike full HGH, it promotes fat metabolism without affecting insulin sensitivity, blood glucose levels, or cell proliferation.

03Human evidence

Demonstrated excellent safety profile and tolerability in obese patients.

Phase II clinical trials involving over 900 patients showed no significant adverse effects, though weight loss efficacy was modest compared to placebo.

No effect on IGF-1 levels or insulin resistance.

Human studies confirmed that AOD-9604 does not increase IGF-1 or alter carbohydrate metabolism, avoiding common HGH side effects.

04Preclinical evidence

Significant reduction in body weight and fat mass in obese mice.

Animal models demonstrated enhanced fat burning, particularly in visceral fat deposits, without affecting lean body mass.

Potential benefits for cartilage repair.

In vitro and animal studies suggest AOD-9604 may promote cartilage regeneration, often researched in combination with hyaluronic acid for osteoarthritis.

05What is known vs. unknown

Reasonably established
  • Derived from the C-terminal fragment of human growth hormone (amino acids 177-191).
  • Specifically targets fat metabolism by increasing lipolysis and decreasing lipogenesis.
  • Does not induce insulin resistance or affect blood sugar levels.
  • Has an excellent safety profile demonstrated in human clinical trials.
  • Emerging research suggests potential applications in joint health and cartilage repair.
Unknowns & limits
  • Long-term efficacy for significant weight loss in humans remains debated due to mixed clinical trial results.
  • Optimal dosing protocols for joint repair and non-metabolic applications are not fully established.
  • The exact receptor mechanism differentiating its action from full HGH is still being elucidated.

06Safety & regulatory context

Regulatory statusAOD-9604 has demonstrated a strong safety profile in human clinical trials, with no significant adverse events related to blood sugar, IGF-1 levels, or tissue growth. Common side effects are mild and typically include injection site reactions. It is not FDA-approved as a prescription medication for weight loss or any other condition, and is primarily available as a research chemical or through compounding pharmacies for investigational use.

07Compared with HGH (Human Growth Hormone)

AOD-9604 vs. HGH (Human Growth Hormone)
Key difference
AOD-9604 only contains the fat-burning portion of HGH, meaning it does not cause cell growth (IGF-1 increase) or insulin resistance.
When researchers discuss each
HGH is discussed for overall growth, recovery, and anti-aging, while AOD-9604 is specifically targeted for fat loss and metabolic regulation without the systemic side effects of HGH.
