PT-141 research overview
PT-141, known in the literature as bremelanotide, is a cyclic heptapeptide analogue in the melanocortin family, structurally related to Melanotan 2. TrueBond Labs carries PT-141 as a 10 mg lyophilized powder in a 3 mL vial, priced accessibly for laboratory programs. Before any lot reaches inventory, an independent third-party facility runs HPLC and mass-spectrometry analysis, and only material verifying at 99% purity or above is accepted.
The compound is used in laboratory investigations of melanocortin-receptor signaling, particularly experiments probing receptor-subtype selectivity and downstream pathway activity within the central nervous system. It has been studied in preclinical research examining how cyclic melanocortin peptides interact with the different members of their receptor family. TrueBond Labs reports these areas without characterizing any findings, and PT-141 is furnished for laboratory research purposes exclusively.
Anyone comparing sources to buy PT-141 can review this catalog's lot-level certificate of analysis at /lab-reports before committing to an order. Standard lyophilized handling applies: −20°C storage for 24+ months of stability, then 2–8°C for reconstituted solutions across a roughly 30-day span. The certificate on file for lot TB-PT1-001 reports 99.7% purity, placing it near the top of the catalog's current results.

PT-141 — frequently asked questions
What is PT-141?+
PT-141, or bremelanotide, is a cyclic seven-amino-acid peptide belonging to the melanocortin analogue family and derived structurally from Melanotan 2. Laboratories study it in the context of melanocortin-receptor signaling. TrueBond Labs sells PT-141 solely as a research chemical; it is not for human or animal use of any kind.
How is TrueBond Labs PT-141 quality verified?+
Each PT-141 lot goes to an independent third-party laboratory for HPLC purity analysis and mass-spectrometry identity confirmation. TrueBond Labs releases a lot only after it verifies at ≥99% purity, and the full certificate of analysis is published at /lab-reports, filed against the lot code carried on every vial.
How should PT-141 be stored in the lab?+
Hold the lyophilized 10 mg vial at −20°C, which supports stability for over 24 months. Once reconstituted for bench procedures, PT-141 solutions belong in the refrigerator at 2–8°C with an expected working window of about 30 days. Minimize light exposure and avoid cycling the vial between frozen and thawed states.
Does TrueBond Labs also sell PT-141 in another format?+
Yes — alongside this 10 mg lyophilized vial, the catalog includes a separate PT-141 nasal spray kit supplied with a metered applicator for research settings. Both formats are covered by lot-level third-party COAs, ship within the United States only, and are restricted to buyers who affirm research use at age 21 or older.
