AOD-9604 vs Sermorelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
AOD-9604
AOD-9604 is a modified fragment of human growth hormone (HGH fragment 176-191). It was developed to have the fat-reducing effects of growth hormone without the adverse effects on blood sugar or growth.
Full details →Sermorelin
Sermorelin is a synthetic analog of GHRH consisting of the first 29 amino acids of the natural hormone. It was previously FDA-approved for GH deficiency diagnosis and treatment in children.

| Aspect | AOD-9604 | Sermorelin |
|---|---|---|
| Mechanism | Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat accumulation) without affecting blood sugar or growth. Works specifically on adipose tissue through a mechanism independent of GH receptors. | Binds to GHRH receptors in the pituitary gland to stimulate natural GH production and release. Maintains the body's natural feedback mechanisms for GH regulation. |
| Typical Dosage | Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg. | Typical dosing: 200-500mcg administered once daily, usually before bed. Some protocols use twice daily dosing. |
| Administration | Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects. | Subcutaneous injection, preferably at bedtime to work with natural GH release patterns. Can be combined with GHRPs for synergistic effects. |
| Side Effects | Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH. | Generally well-tolerated. May cause injection site reactions, headache, flushing, or dizziness. Less side effects than direct GH administration. |
