PT-141 Nasal Spray

About PT-141 Nasal Spray

PT-141 is a cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone, designed around the core MSH receptor-binding sequence. It is supplied here as a sterile nasal spray solution for laboratory research.

In bench research, PT-141 is used in melanocortin-receptor binding assays, where laboratories study its interaction with MC3R and MC4R receptors. Its cyclic structure also makes it a useful reference for comparing conformational stability against linear peptide standards.

Pickering Peptides holds every batch to strict quality standards. Each lot is verified by independent third-party HPLC and mass-spectrometry testing at 99% purity or higher, then sealed in a sterile spray bottle. Orders ship with tracking, and every order includes the batch report key so you can verify the lab results directly with the testing laboratory.
