Selank vs Melanotan I
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Selank
Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement.
Full details →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.

| Aspect | Selank | Melanotan I |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | Binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection without UV exposure. |
| Typical Dosage | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Clinical: 16mg implant every 2 months. Research protocols for tanning typically use 0.5-1mg daily for loading, then maintenance dosing. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | FDA-approved form is a subcutaneous implant. Research use involves subcutaneous injection. Often combined with minimal UV exposure to enhance results. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Nausea (especially initially), facial flushing, fatigue, headache, and darkening of existing moles or freckles. |
