AOD-9604 vs GHRP-2

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.

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.

Side-by-Side Comparison

Aspect	AOD-9604	GHRP-2
Dose Range	300 mcg–500 mcg	100 mcg–300 mcg
Frequency	1x daily	3x daily
Cycle Length	12–24 weeks	8–12 weeks
Route	subcutaneous	subcutaneous
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 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.
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. Often stacked with GHRH peptides for enhanced GH release.
Administration	Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.	Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep.
Side Effects	Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.	Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations.
Best For	Fat Loss	Muscle Growth Fat Loss Sleep Quality
