PT-141

PT-141, also called Bremelanotide, is a synthetic peptide classified as a melanocortin agonist. In the research literature it is studied within melanocortin-signaling and arousal-pathway models, where investigators examine its interaction with melanocortin receptors. VANTA supplies it strictly as a reference compound for in-vitro and laboratory research.

VANTA supplies PT-141 as a lyophilized powder. Each lot is assessed by reversed-phase HPLC for chromatographic purity and confirmed by mass spectrometry for identity, so researchers can attribute experimental results to the intended peptide rather than to impurities or truncation products.

The sealed lyophilized vial is generally stored at -20C and protected from light. Researchers reconstitute it with an appropriate solvent before laboratory use and typically hold the reconstituted solution at 2-8C, following their own institutional protocols rather than any fixed guidance.

Yes. Every PT-141 batch ships with a per-batch Certificate of Analysis documenting the HPLC purity result and the mass-spectrometry identity confirmation for that specific lot. This per-lot documentation lets a laboratory match the vial in hand to its own analytical record for traceable, reproducible work.

In the published literature, PT-141 is examined as a melanocortin-receptor agonist within research on melanocortin signaling and central arousal pathways. These are observations described in animal and in-vitro models only and are summarized to orient researchers to the literature, not as statements about any outcome in humans.

No. PT-141 is sold strictly for laboratory and in-vitro research use by qualified professionals. It is not a drug, supplement, or medical product and is not intended for human or veterinary consumption, administration, or any clinical, diagnostic, or therapeutic application.
