Side Effects

Injection site reactions
CommonMild

Mild redness, swelling, or bruising at the injection site. Typically resolves within 1-2 hours. Minimise by allowing the solution to reach room temperature, using proper injection technique, and rotating injection sites. Apply ice if swelling persists.

Headache
UncommonMild

Mild to moderate headache reported in some users, typically occurring within 1-2 hours of injection. Usually self-resolving within a few hours. Ensure adequate hydration and consider taking the injection with a light meal if headaches persist.

Flushing or facial warmth
UncommonMild

Transient flushing or sensation of warmth in the face or upper body, typically lasting 15-30 minutes. No intervention required; resolves spontaneously.

Dizziness or lightheadedness
UncommonMild

Mild dizziness reported in some users, particularly if injected while standing. Sit or lie down for 5-10 minutes after injection if this occurs. Ensure adequate hydration.

Nausea
UncommonMild

Mild nausea reported in some users, typically transient. Taking the injection with a small amount of food or ginger may help. If persistent, consult a healthcare provider.

Lipodystrophy (localised fat loss)
UncommonModerate

Repeated injections in the same site can cause localised fat loss or indentation of the skin due to the lipolytic effects of the peptide. Prevent by strictly rotating injection sites with each dose, maintaining at least 1 inch between injection points, and cycling through at least 4 different anatomical sites.

Hypoglycaemia (low blood sugar)
RareModerate

Although AOD-9604 does not directly affect insulin secretion, increased fat oxidation may theoretically lower blood glucose in susceptible individuals, particularly those with diabetes or on glucose-lowering medications. Monitor blood glucose if diabetic. Seek medical attention if symptoms of hypoglycaemia (tremor, sweating, confusion) occur.

Allergic reaction
RareSerious

Severe allergic reactions (anaphylaxis) are extremely rare but possible. Symptoms include difficulty breathing, swelling of the face or throat, severe rash, or rapid heartbeat. Seek emergency medical attention immediately if these symptoms occur. Discontinue use and inform your healthcare provider of any known allergies to growth hormone or peptides.

Carpal tunnel syndrome
RareModerate

Prolonged use of growth hormone fragments may rarely cause carpal tunnel syndrome due to fluid retention or tissue changes. Symptoms include numbness, tingling, or weakness in the hand or wrist. If symptoms develop, discontinue use and consult a healthcare provider.

Reconstitution Guide

Do not use saline or bacteriostatic saline — use only bacteriostatic water for reconstitution

Do not shake the vial vigorously; gentle swirling prevents peptide degradation

Discard immediately if the solution appears cloudy, discolored, or contains visible particles

Use within 30 days of reconstitution when stored at 2–8°C

Do not freeze the reconstituted solution; freezing may denature the peptide

Half-lifeApproximately 30 minutes (subcutaneous)
SequenceYRGETGQAAFNGWMTEGE

AOD-9604 is a synthetic C-terminal fragment of human growth hormone (amino acids 176-191) that activates the GH receptor on adipose tissue, specifically triggering lipolysis (fat breakdown) without stimulating insulin secretion or affecting blood glucose levels. Unlike full-length growth hormone, this fragment selectively targets fat metabolism through the GH secretagogue pathway, making it useful for metabolic research and weight management studies.

GH Receptor Activation on Adipocytes

AOD-9604 binds to growth hormone receptors on fat cells, activating intracellular signalling cascades that promote the breakdown of triglycerides into free fatty acids and glycerol. This lipolytic effect is independent of the metabolic effects of full GH on glucose and insulin.

Lipid Mobilisation

The peptide increases hormone-sensitive lipase activity in adipose tissue, which hydrolyses stored triglycerides. Released free fatty acids are then available for oxidation by other tissues, increasing energy expenditure.

Metabolic Selectivity

AOD-9604 does not activate the insulin-like growth factor-1 (IGF-1) pathway or stimulate insulin secretion, distinguishing it from full-length GH and making it suitable for metabolic studies in glucose-sensitive populations.

  • AOD-9604 is a synthetic fragment of human growth hormone (hGH 176-191) designed to retain lipolytic activity while eliminating metabolic side effects associated with full GH
  • The peptide selectively activates lipolysis in adipose tissue without affecting insulin secretion or blood glucose levels, making it distinct from full-length growth hormone
  • Research indicates AOD-9604 increases fat oxidation and may enhance weight loss when combined with caloric restriction and exercise
  • The mechanism involves GH receptor activation on adipocytes, triggering hormone-sensitive lipase and promoting triglyceride breakdown
  • Subcutaneous administration results in rapid absorption with a half-life of approximately 30 minutes, requiring daily dosing for sustained effect
