PT-141 (Bremelanotide) 10mg is a high-purity research peptide widely studied for melanocortin receptor signaling, neuroendocrine physiology, hormone regulation, receptor pharmacology, and peptide biology. Third-party tested, COA verified, and intended strictly for laboratory research purposes.
PT-141 is a synthetic melanocortin peptide studied for its activity at melanocortin receptors and its involvement in neurological, behavioral, and central signaling pathways.
Melanocortin Receptor Research
Studied for its activity at melanocortin receptors and their associated signaling mechanisms.
Neurological Signaling
Investigated in experimental models involving central nervous system signaling pathways.
Behavioral Research
Used in laboratory research examining melanocortin-mediated behavioral and physiological responses.
Central Melanocortin Pathways
Researched for its interaction with central melanocortin pathways and related biological signaling.
What PT-141 is
PT-141, also called bremelanotide, is a melanocortin receptor ligand that emerged from the same chemistry as Melanotan II but with a substantially narrower receptor profile.
That narrowing is the point of the compound. In a receptor family whose subtypes are distributed across pigmentation, energy balance and sexual function, a selective ligand is a fundamentally different research tool from a broad one — it isolates a subset of the family rather than engaging it wholesale.
Handling and reconstitution
Standard lyophilised peptide handling applies. Keep the sealed vial cold and dark until it is used. Reconstitute by running bacteriostatic water slowly down the inside wall of the vial rather than firing it onto the powder cake, and let it dissolve without shaking — swirl gently if it needs help.
The concentration you end up with is set by how much water you add, not by the vial size. Our reconstitution calculator turns vial mass and water volume into a concentration and a syringe reading.
Storage
Sealed and lyophilised: refrigerated, protected from light. In solution: refrigerated, and treat time at room temperature as a cost. Avoid repeated freeze-thaw once reconstituted.
What ships, and what is on the certificate
The vial ships sealed as it was filled. Every compound in the catalogue is tested by an outside laboratory — Vanguard Laboratory in Olympia, Washington — and the certificate is published in full rather than summarised.
The certificate reports chromatographic purity by HPLC with the chromatogram visible, the measured quantity in milligrams, and an endotoxin result by LAL. Measured quantity usually reads slightly above the label, which is normal: fills are targeted high so every vial meets its stated content.
Frequently asked questions
Is PT-141 the same as Melanotan II?
No. It shares an origin in the same chemistry but is markedly more selective across melanocortin receptor subtypes, which is the whole distinction.
What does bremelanotide refer to?
It is the other name for the same compound.
How should it be reconstituted?
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve without shaking. The reconstitution calculator will convert vial mass and water volume into a concentration and a syringe reading.
Does it come with a certificate of analysis?
Yes. Every compound is tested by an independent laboratory and the full certificate, chromatogram included, is published on the site rather than summarised.
Is this a medicine?
No. It is sold for in-vitro laboratory research use only. It is not a drug, supplement or cosmetic, and is not for human or veterinary use.
