UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

For in-vitro laboratory research only
PT-141 is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About PT-141 in the lab
A non-selective melanocortin-receptor agonist that serves as a reference ligand for MC3R/MC4R pharmacology in vitro.
Proposed mechanism
Agonist mainly at MC4R and MC3R in the central nervous system, acting on hypothalamic pathways rather than vascular ones; it has weaker MC1R activity than Melanotan II.
Structure note
Cyclic lactam-bridged analogue related to α-MSH, based on the Melanotan II scaffold.
Typical research themes
- MC receptor subtype assays
- Cyclic-peptide chemistry
- cAMP signalling
Regulatory note
The same active substance is a licensed prescription medicine in some countries. Research-grade material is not a medicine and must never be used on people or animals.
This profile is a short, general summary of publicly discussed science. It is not exhaustive, not peer-reviewed by PeptideCompare, and is not medical advice. PeptideCompare provides no dosing, protocol or usage guidance — nothing here is for human or veterinary use.
