Melanotan I vs Syn-Ake
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Melanotan I
Melanotan I (afamelanotide) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH). It is FDA-approved as Scenesse for erythropoietic protoporphyria (EPP), a rare genetic disorder causing severe sun sensitivity.

Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate) is a synthetic tripeptide that mimics the effect of Waglerin-1, a peptide found in Temple Viper venom. It's used in cosmetics for anti-wrinkle effects.

| Aspect | Melanotan I | Syn-Ake |
|---|---|---|
| Mechanism | Binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection without UV exposure. | 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 Dosage | Clinical: 16mg implant every 2 months. Research protocols for tanning typically use 0.5-1mg daily for loading, then maintenance dosing. | Topical: 1-4% concentration in serums or creams. Applied 1-2 times daily to target areas like forehead and crow's feet. |
| Administration | FDA-approved form is a subcutaneous implant. Research use involves subcutaneous injection. Often combined with minimal UV exposure to enhance results. | Topical application only. Should be applied to clean skin. Often combined with other anti-aging peptides for synergistic effects. |
| Side Effects | Nausea (especially initially), facial flushing, fatigue, headache, and darkening of existing moles or freckles. | Generally well-tolerated topically. Rare reports of mild skin irritation or sensitivity. |
