What is AOD-9604 and how does it work?

AOD-9604 (Anti-Obesity Drug 9604) is a modified 16-amino acid fragment of human growth hormone (amino acids 176-191). It retains the fat-burning properties of HGH without affecting blood sugar, insulin, or muscle growth. It works by stimulating lipolysis (fat breakdown) and inhibiting lipogenesis (fat storage) by targeting beta-adrenergic receptors in adipose tissue.

What results can I realistically expect?

Based on clinical trials: approximately 2.6 kg (5.7 lbs) average fat loss over 12 weeks vs 0.8 kg for placebo - a net difference of about 4 lbs additional fat loss when combined with diet and exercise. Results are modest but measurable. AOD-9604 is not a magic solution; it enhances a solid diet and exercise program.

How long until I see results?

Visible results typically require 6-8 weeks of consistent use. Significant, measurable fat loss is usually seen at the 12-week mark. The peptide works gradually - don

What is the optimal AOD-9604 dosage?

Standard dosing ranges from 300-500 mcg daily, taken subcutaneously in the morning on an empty stomach (30-60 minutes before first meal). Clinical trials showed no benefit from higher doses (5mg, 10mg produced similar results to 1mg), suggesting a ceiling effect around 300-500 mcg.

Does AOD-9604 affect blood sugar or insulin?

No. Unlike full HGH, AOD-9604 does not affect blood sugar levels, insulin sensitivity, or IGF-1. This is because it only contains the lipolytic (fat-burning) region of HGH without the metabolic and growth-promoting regions. This makes it suitable for those concerned about metabolic effects.

How does AOD-9604 compare to GLP-1 medications?

GLP-1 agonists (Semaglutide, Tirzepatide) produce dramatically greater weight loss (15-24% of body weight) through appetite suppression. AOD-9604 produces modest fat loss (~4 lbs extra over 12 weeks) through direct fat metabolism. GLP-1s are FDA-approved with extensive data; AOD-9604 is a research peptide. Choose based on your goals and comfort with each approach.

AOD-9604 has been tested in 900+ participants across six randomized trials with a favorable safety profile. Common side effects are mild: injection site reactions and occasional headaches. It failed to achieve statistical significance in Phase IIb trials, which is why development was terminated - but safety was not a concern. Medical supervision is still recommended.

Can athletes use AOD-9604?

No. AOD-9604 is banned by WADA (World Anti-Doping Agency) and is prohibited in competitive sports. Athletes subject to drug testing should not use this peptide.
