AOD-9604 vs Mod GRF 1-29
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 →Mod GRF 1-29
Mod GRF 1-29 (Modified GRF 1-29, also called CJC-1295 without DAC or Tetrasubstituted GRF 1-29) is a modified growth hormone-releasing hormone analog with improved stability over natural GHRH.

| Aspect | AOD-9604 | Mod GRF 1-29 |
|---|---|---|
| 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 growth hormone release. Four amino acid substitutions improve resistance to enzymatic degradation while maintaining biological activity. |
| 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: 100-300mcg administered 2-3 times daily, usually combined with a GHRP like Ipamorelin for synergistic effects. |
| Administration | Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects. | Subcutaneous injection. Best administered on empty stomach. Short half-life (~30 minutes) necessitates multiple daily doses, unlike DAC version. |
| Side Effects | Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH. | Flushing, headache, dizziness, and injection site reactions. Generally well-tolerated. May cause water retention. |
