PT-141 10mg: A Melanocortin Receptor Research Peptide

PT-141 also goes by Bremelanotide. It's a synthetic peptide, seven amino acids, built into a ring shape instead of a straight chain. Scientists derived it from a peptide called Melanotan II, then changed it a bit. It comes from alpha MSH originally, a hormone tied to the melanocortin system.

Quick Facts

Name: PT-141
Scientific name: Bremelanotide
Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH
Formula: C50H68N14O10
Weight: about 1025.2 g/mol
CAS number: 189691-06-3
Look: White to off white lyophilized powder

What Makes It Different

A lactam bridge locks the peptide into a ring. That ring shape gives it more stability than straight chain versions. Researchers also point to a D-Phe swap in the sequence, which helps it resist breaking down during lab studies.

What Labs Study It For

Researchers look at PT-141 in work covering:

Melanocortin receptor binding, MC1R, MC3R, MC4R, MC5R
Receptor subtype selectivity
cAMP signaling pathways
Central nervous system melanocortin research
Structure activity relationships compared to Melanotan II

Some labs also pair PT-141 studies with GHK-Cu, especially when comparing receptor based and tissue based peptide research side by side.

Regulatory Status

PT-141's active molecule has one FDA approved use elsewhere, but this product is sold strictly as a research compound, not approved for any treatment use in this form.

Legal and Safety Info

Not a supplement, just a raw research compound. Keep away from kids. Long term safety data is limited, so only trained lab personnel should handle this.

Buying this means agreeing to use it legally, for research only.
