What is the difference between Afamelanotide and KPV?

Afamelanotide (Afamelanotide (Scenesse)) is graded A and is FDA-approved (2019) for erythropoietic protoporphyria (EPP). KPV (α-MSH Tripeptide KPV) is graded C+ and is Not FDA-approved — research peptide. They are commonly compared because they share the categories: skin.

Which has stronger clinical evidence — Afamelanotide or KPV?

On our internal evidence scale, Afamelanotide is A and KPV is C+. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of Afamelanotide vs KPV?

Afamelanotide: 16 mg subcutaneous implant every 2 months (clinical use). KPV: 200–500 mcg orally or topical (research only). Always work with a licensed clinician — peptide dosing should be individualized.

Afamelanotide vs KPV

Both Afamelanotide and KPV are used for skin. Here's how their evidence, dosing, and regulatory status actually compare.

Afamelanotide

Evidence A

Afamelanotide (Scenesse)

An FDA-approved selective MC1R agonist used to increase eumelanin density in erythropoietic protoporphyria patients. Off-label cosmetic tanning use is widespread internationally.
