AOD-9604 vs Melanotan I

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.

Side-by-Side Comparison

AspectAOD-9604Melanotan I
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.Binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection without UV exposure.
Typical DosageResearch dosing typically ranges from 250-500mcg daily, often split into morning and afternoon doses. Some protocols use higher doses up to 1mg.Clinical: 16mg implant every 2 months. Research protocols for tanning typically use 0.5-1mg daily for loading, then maintenance dosing.
AdministrationSubcutaneous injection, typically in the abdominal area. Best administered on an empty stomach. Can be combined with exercise for enhanced effects.FDA-approved form is a subcutaneous implant. Research use involves subcutaneous injection. Often combined with minimal UV exposure to enhance results.
Side EffectsGenerally well-tolerated. May cause headaches, injection site reactions, or temporary lethargy. Does not affect blood glucose like full GH.Nausea (especially initially), facial flushing, fatigue, headache, and darkening of existing moles or freckles.
