A fragment of growth hormone designed to mobilise fat without the wider systemic effects of full GH.
AOD-9604 is a synthetic peptide modelled on a fragment of human growth hormone. It was developed to retain the lipolytic, fat-mobilising effects of growth hormone without the wider metabolic and growth effects. For clients with stubborn fat that has not responded to diet and exercise, it is one tool in the body composition toolkit.
How it works. AOD-9604 signals the breakdown of stored triglycerides and reduces the rate at which new fat is stored. It does not directly cause weight loss, what it does is shift the balance of fat metabolism so that, paired with appropriate diet and training, fat loss occurs more readily.
Who tends to benefit. Clients in a sustained calorie deficit who have plateaued. Those with localised, stubborn fat that diet alone has not shifted. Clients whose body composition has stalled despite consistent training. AOD-9604 is not for clients new to a fat loss programme, the foundational work of diet and movement needs to be in place first.
What to expect. The protocol is typically 8 to 12 weeks of daily subcutaneous injections via a medical-grade prefilled pen. The peptide is delivered each morning. The injection technique is shallow and the dose is small.
Realistic outcome. Most clients see a measurable shift in body composition across a 12-week course paired with appropriate diet and training. Body composition shifts more than scale weight in many cases. We measure with InBody scans at baseline, midpoint, and end to track this objectively.
What it is not. A magic body composition fix. The peptide accelerates the work, it does not replace it. Clients hoping for transformation without effort will be disappointed. The clients who get the best result are the ones who treat the peptide as an enhancement of a programme they are already running.
We screen with blood work before starting, particularly fasting glucose, lipids, and liver function. Diabetic clients need specific clearance. We do not run AOD-9604 alongside other growth hormone secretagogues without specific protocol planning.
The honest framing. AOD-9604 is a tool for clients who are committed to body composition work and want a measurable accelerant. It is not a substitute for the underlying work.
