PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide investigated for its interaction with melanocortin receptors. It is structurally related to melanotan-II and is studied as a distinct melanocortin receptor agonist.
In controlled laboratory environments, PT-141 may be investigated in connection with melanocortin-receptor binding, receptor selectivity, intracellular signaling, neurological pathways, behavioral models, and structure–activity relationships.
Full research description
Published research has examined bremelanotide in relation to melanocortin receptors involved in central nervous-system signaling. However, these findings should not be interpreted as establishing that this independently supplied research material enhances sexual desire, treats erectile dysfunction, improves sexual performance, affects pigmentation, or provides any therapeutic benefit in humans or animals.
Bremelanotide is also the active ingredient in the FDA-approved prescription product Vyleesi. Vyleesi is approved for certain premenopausal women with acquired, generalized hypoactive sexual desire disorder. It is not approved for men, for erectile dysfunction, for general sexual enhancement, or for improving sexual performance.
That approval applies only to the regulated Vyleesi drug product and does not extend to independently supplied PT-141 research materials. This product is not represented as Vyleesi, is not interchangeable with an FDA-approved pharmaceutical product, and has not been established as safe, effective, sterile, or suitable for administration.
References to dosing, injection timing, onset of effects, sildenafil use, erection duration, increased dopamine release, or treatment of sexual dysfunction have been omitted because such statements could imply clinical instructions, drug equivalence, or intended human use.
The terms PT-141, bremelanotide, bremelanotide acetate, and differently formulated or modified melanocortin peptides should not automatically be treated as interchangeable. Peptide sequence, salt form, purity, molecular identity, potency, and composition should be verified using batch-specific analytical documentation.
Storage & handling
Before reconstitution. Keep the sealed vial cool and dark. Lyophilized peptides are stable this way for the period stated on the certificate.
Reconstitution. Add bacteriostatic water slowly against the inside wall of the vial. Swirl gently to dissolve — never shake, as agitation can damage the peptide chain.
After reconstitution. Store refrigerated and use within the window appropriate for the compound under study. Do not freeze once in solution.
Check that the batch code on the label matches your packing slip on arrival.
COA & testing
Every batch is analysed by an independent laboratory before it is listed. The method for this compound is HPLC-UV 214nm.
The certificate shows the main peak purity, the impurity profile, the test date and the laboratory that performed it — tied to the batch code printed on your vial.
