PEG-MGF vs AOD-9604
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
PEG-MGF
PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.
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.

| Aspect | PEG-MGF | AOD-9604 |
|---|---|---|
| Mechanism | Activates muscle satellite cells (stem cells) and promotes their fusion to existing muscle fibers for repair and growth. MGF is produced naturally in response to mechanical stress on muscles. | 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 | Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout. | Research dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg. |
| Administration | Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant. | Subcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects. |
| Side Effects | Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated. | Generally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH. |
