Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research

Copper Peptide AHK-Cu

Also: Tripeptide-3, Ala-His-Lys Copper

Research

A copper-binding tripeptide primarily used for hair growth stimulation. Shows promise for both hair loss prevention and scalp health.

Skin & HairLimited Research
Melanotan I

Also: Afamelanotide, Scenesse

FDA Approved

A 13-amino acid synthetic analog of α-MSH that stimulates melanin production. FDA-approved (as Scenesse) for treating phototoxicity in patients with erythropoietic protoporphyria (EPP). More selective than Melanotan II with fewer side effects.

Skin & HairFDA Approved

Mechanism of ActionAHK-Cu binds copper and delivers it to hair follicles where it supports various enzymatic processes. It stimulates hair follicle cells, extends the growth phase of hair, and has wound-healing properties on the scalp.Melanotan I binds to melanocortin 1 receptors (MC1R) on melanocytes, stimulating eumelanin production. This increases skin pigmentation and provides photoprotection. Unlike MT-II, it has minimal affinity for MC3R and MC4R, resulting in fewer sexual and appetite-related side effects.

Research SummaryStudies show increased hair count and thickness. Research demonstrates activation of hair follicle stem cells. Often combined with other hair growth peptides for synergistic effects.FDA approved in 2019 for EPP after successful Phase III trials showing significant increase in pain-free time in sunlight. Also studied for vitiligo, polymorphous light eruption, and solar urticaria. Clinuvel Pharmaceuticals developed and markets it as Scenesse.

Frequently Asked Questions: Copper Peptide AHK-Cu vs Melanotan I

What is the difference between Copper Peptide AHK-Cu and Melanotan I?

Copper Peptide AHK-Cu is a skin & hair peptide that a copper-binding tripeptide primarily used for hair growth stimulation. shows promise for both hair loss prevention and scalp health. Melanotan I is a skin & hair peptide that a 13-amino acid synthetic analog of α-msh that stimulates melanin production. fda-approved (as scenesse) for treating phototoxicity in patients with erythropoietic protoporphyria (epp). more selective than melanotan ii with fewer side effects. The main differences lie in their mechanisms of action and clinical applications.

Which is better, Copper Peptide AHK-Cu or Melanotan I?

Neither is universally "better" - the choice depends on your specific goals. Copper Peptide AHK-Cu is typically used for skin & hair purposes, while Melanotan I is used for skin & hair. Always consult with a healthcare provider to determine which may be appropriate for your situation.

Can Copper Peptide AHK-Cu and Melanotan I be used together?

Some peptide protocols combine multiple compounds for synergistic effects.
