- Before reviewing the distinctions, understand this: the peptide sequence is identical. The differences lie in manufacturing, delivery, and regulatory status.
- Peptide sequence
- [Nle4,D-Phe7]-α-MSH (13 amino acids)
- Molecularly identical. Same active compound
- Regulatory status
- Unregulated research peptide
- FDA/EMA-approved orphan drug (Scenesse)
- Only afamelanotide is legally prescribed
- Delivery method
- Subcutaneous injection (lyophilised powder reconstituted)
- Subcutaneous implant (16mg sustained-release rod)
- Implant maintains plasma levels for 60 days
- Clinical indication
- None (used experimentally for tanning)
- Erythropoietic protoporphyria (EPP) only
- Afamelanotide is prescribed for a specific rare disease
- Manufacturing oversight
- Variable (academic or grey-market sourcing)
- cGMP facilities with FDA batch oversight
- Pharmaceutical-grade guarantees potency and sterility
- Dosing protocol
- Inconsistent (typically 0.5–2mg daily injections)
- 16mg implant every 60 days (clinical trial validated)
- Afamelanotide dosing is standardised from Phase III data
