PT-141
Melanocortin Receptor Agonist Peptide 10mg
Original price was: $65.00.$45.50Current price is: $45.50.
PT-141 (Bremelanotide) is a synthetic cyclic melanocortin-receptor agonist that places central nervous system signaling at the center of its research profile. Its activity, particularly at MC4R, is studied in pathways associated with sexual motivation and arousal. This receptor-focused mechanism distinguishes PT-141 from compounds centered primarily on peripheral vascular signaling, offering a different approach to this area of neuroendocrine research.

⚠️ Important Disclaimer
Research purposes only. Not for human consumption or therapeutic treatment.
PT-141, also called bremelanotide, is studied through the melanocortin signaling system. Its research profile is centered on receptor activity and neural signaling, rather than a direct action on blood vessels.
What researchers investigate
- Receptor activity: Investigate melanocortin-receptor responses, including MC4R-associated signaling.
- Neural pathways: Examine the cellular messages studied in neuroendocrine signaling models.
- Mechanism comparisons: Compare receptor-driven activity with compounds that work through different signaling systems.
What makes it different?
PT-141 is a distinct cyclic peptide. It is related to, but is not interchangeable with, Melanotan II.
Research findings describe the materials and conditions studied; they do not predict results in people.

What the results mean
- Identity: checks whether the tested sample matches the reported compound.
- Purity: measures the chromatographic purity reported by the method; it is different from milligrams in a vial.
- Content: reports how much material was measured in the tested sample.
A certificate documents the tested sample and the tests shown. It does not establish clinical effectiveness or regulatory approval. Purity testing is not a sterility test.
Handling & Storage
Good handling protects the integrity of your research sample. Use the product label, any matching technical documentation and your laboratory’s approved procedure for this exact material.
- Check before opening: confirm the compound, vial size and relevant report.
- Keep dry material protected: minimize unnecessary exposure to moisture, light and temperature changes; follow the storage instructions supplied with your vial.
- Choose the solvent for the material: solubility and stability vary. Water, saline, PBS and acidic solutions are not automatically interchangeable.
- Label prepared samples: record the contents, concentration, preparation date and validated storage period. Use aliquots where appropriate to reduce repeated handling.
There is no universal reconstitution volume or shelf life for every peptide. A clear solution alone does not confirm identity, stability or sterility.
FAQ
What is the labeled amount?
10 mg per vial. For a blend, this is the total of the listed components. A concentration is calculated only after the final solution volume is known.
Where can I check the testing?
The Certificate of Analysis tab displays COA8271 from Bioviridian Inc. Open the full-size image and use the lab’s verification page to check the report. Confirm the sample size and how the report relates to your vial.
Is purity the same as the amount in the vial?
No. Purity is a measurement made by an analytical method; content is the measured amount of material. A high purity percentage does not, by itself, tell you how many milligrams are present.
How should I interpret the research?
A published result for a prescription formulation does not establish an outcome, safety profile or approved use for this research material.
