Melanotan I vs BPC-157 & TB-500 (Wolverine Stack)
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.

| Aspect | Melanotan I | BPC-157 & TB-500 (Wolverine Stack) |
|---|---|---|
| Mechanism | Binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection without UV exposure. | BPC-157 upregulates growth factor expression and promotes angiogenesis, while TB-500 promotes cell migration and differentiation through actin regulation. Together, they enhance wound healing, reduce scar tissue formation, and support musculoskeletal recovery through complementary pathways. |
| Typical Dosage | Clinical: 16mg implant every 2 months. Research protocols for tanning typically use 0.5-1mg daily for loading, then maintenance dosing. | Typical research protocols: BPC-157 at 250-500mcg daily combined with TB-500 at 2-2.5mg twice weekly during loading phase, then 2mg every 2 weeks for maintenance. |
| Administration | FDA-approved form is a subcutaneous implant. Research use involves subcutaneous injection. Often combined with minimal UV exposure to enhance results. | Both peptides administered via subcutaneous injection. Some protocols suggest injecting near injury sites for localized effects. Can be injected separately or as a pre-mixed blend. |
| Side Effects | Nausea (especially initially), facial flushing, fatigue, headache, and darkening of existing moles or freckles. | Generally well-tolerated. May include mild nausea, temporary fatigue, headache, or localized irritation at injection sites. |
