Melanotan II vs Syn-Ake

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Melanotan II

Melanotan II is a synthetic peptide analog of α-MSH with broader receptor activity than Melanotan I. It produces tanning effects and has notable effects on sexual function and appetite suppression.

Side-by-Side Comparison

AspectMelanotan IISyn-Ake
MechanismNon-selective melanocortin receptor agonist affecting MC1R (tanning), MC3R and MC4R (sexual function and appetite). This broader activity explains its multiple effects beyond tanning.Acts as a competitive antagonist at the nicotinic acetylcholine receptor, reducing muscle contractions similar to Botox but through a different mechanism. Provides muscle-relaxing effects when applied topically.
Typical DosageTypical protocols: 0.25-0.5mg daily during loading phase for 1-2 weeks, then 0.5-1mg before UV exposure for maintenance. Start low to assess tolerance.Topical: 1-4% concentration in serums or creams. Applied 1-2 times daily to target areas like forehead and crow's feet.
AdministrationSubcutaneous injection. Usually combined with UV exposure for tanning effects. Nasal spray formulations exist but have lower bioavailability.Topical application only. Should be applied to clean skin. Often combined with other anti-aging peptides for synergistic effects.
Side EffectsNausea (common initially), facial flushing, spontaneous erections, increased libido, appetite suppression, and mole darkening.Generally well-tolerated topically. Rare reports of mild skin irritation or sensitivity.
