About PT-141NasalSpray
PT-141 nasal spray in Canada is supplied by Horizon Peptides as a pre-prepared 30 mg research spray bottle, available singly or in 3-bottle and 5-bottle packs. PT-141, also known as bremelanotide, is a synthetic cyclic melanocortin peptide studied in laboratory models of melanocortin receptor signalling.
PT-141 is a seven-amino-acid cyclic peptide derived from the melanocortin peptide family. Its structure incorporates norleucine and D-phenylalanine alongside a cyclic configuration designed to produce a more stable research analogue than naturally occurring melanocortin sequences.
Laboratory interest centres primarily on melanocortin receptor activity, particularly signalling involving the MC3 and MC4 receptor pathways. These receptors are involved in a range of central nervous system signalling processes and make PT-141 useful in receptor-binding, pathway-response, and structure-activity research.
Its compact cyclic structure also makes PT-141 a useful comparison compound when studying how peptide cyclisation and amino-acid substitution influence receptor affinity and molecular stability.

Other PT-141 formats and related research peptides
PT-141 is also stocked as the PT-141 lyophilized vial. Researchers studying related melanocortin sequences may also work with other peptides in the melanocortin family for comparative receptor and structure-activity research.

Testing and documents
Batch documents are published on the Lab Results page as they become available, searchable by product or batch.
What a certificate of analysis shows
-
Identity
Mass spectrometry checks the measured molecular mass against the expected one: is this the right molecule.
-
Purity
HPLC separates a sample and reports the target as a share of everything detected.
-
Batch
A certificate describes one batch. The batch on the document should match the one you are asking about.
-
Date and analyst
The document should say who carried out the analysis and when.
Not every batch has a published document. Where one exists, it is listed; this page says nothing about results.
