PT-141

About PT-141

PT-141 is a synthetic cyclic heptapeptide derived from alpha-melanocyte-stimulating hormone (alpha-MSH). It was developed as a research tool for the melanocortin receptor system and remains a reference compound for this pathway.

Laboratories study PT-141 in neuroscience and behavioural research models investigating melanocortin-4 receptor signalling, as well as in cell-based receptor-binding assays. It is a well-characterized compound for melanocortin research programs.

Every Pickering Peptides lot is third-party tested by HPLC and mass spectrometry at 99%+ purity before it ships. Vials arrive sealed as a lyophilized (freeze-dried) powder from our Ontario, Canada facility, and every order includes the batch report key so you can verify the lab results directly with the testing laboratory.
