GHRP-2 vs AOD-9604
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
GHRP-2
Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
Full details →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 →Side-by-Side Comparison
| Aspect | GHRP-2 | AOD-9604 |
|---|---|---|
| Mechanism | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. | 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. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. | Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg. |
| Administration | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. | Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects. |
| Side Effects | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. | Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH. |
