AOD-9604 vs PEG-MGF

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.

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.

Side-by-Side Comparison

AspectAOD-9604PEG-MGF
MechanismStimulates 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.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.
Typical DosageResearch dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg.Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout.
AdministrationSubcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant.
Side EffectsGenerally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated.
