Overview
About PT-141 10mg
PT-141 10mg (Bremelanotide) is a synthetic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH), supplied as a reference compound for laboratory and in-vitro research use only. Its receptor selectivity is well characterized, which makes it a defined tool for probing central melanocortin signaling.
In cell-culture and preclinical models, PT-141 functions as a potent agonist at melanocortin receptors — primarily MC4R, with reported activity at MC1R and MC3R — engaging centrally expressed melanocortin receptor populations. Its well-mapped receptor profile makes it a frequent point of reference in melanocortin structure–activity work.
Key research areas
Melanocortin receptor signaling, with emphasis on MC4R and secondary MC1R/MC3R activity
Neuroendocrine pathways and hypothalamic signaling models
Receptor-binding and functional (cAMP accumulation) assays across melanocortin receptor subtypes
Comparative structure–activity studies across cyclic α-MSH analogs

Working with the 10mg vial
This vial contains 10 mg of lyophilized material. Reconstitution does not change that mass — it changes the volume it occupies — so the concentration you end up with is set entirely by how much diluent you add.

Frequently Asked Questions
What is PT-141 (Bremelanotide)?
PT-141 is a synthetic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH) that acts as an agonist at melanocortin receptors, primarily MC4R with additional activity at MC1R and MC3R. Echo Peptides supplies it as a lyophilized reference compound strictly for in-vitro laboratory research, not for human or veterinary use.
What do laboratories study PT-141 for?
Researchers use PT-141 as a reference agonist in cell-culture and preclinical models of melanocortin receptor signaling and neuroendocrine pathways. Published work has referenced it in receptor-binding and functional assays, hypothalamic signaling models, and comparative structure–activity studies across α-MSH analogs — all confined to in-vitro and preclinical settings.
Is PT-141 third-party tested, and how should it be stored?
Each offering is third-party tested for identity and purity, and a Certificate of Analysis is available on request. The 10mg product is supplied as a lyophilized white powder and should be refrigerated at 2–8°C to maintain stability for research use.
