What is PT-141?

PT-141, internationally known as bremelanotide, is a cyclic heptapeptide. Structurally it is closely related to Melanotan II, from which it was derived as a metabolite.

The cyclic lactam structure gives the molecule high stability. PT-141 acts as an agonist mainly at the melanocortin receptors MC3R and MC4R.

PT-141 in research

Research uses PT-141 to study central melanocortin signalling pathways in the brain. These pathways are involved in regulating numerous behavioural and metabolic processes.

Unlike Melanotan II, the focus with PT-141 is not on pigmentation but on the receptor pharmacology of MC3R and MC4R.

Technical data

The certificate of analysis for each batch is authoritative.

What you receive

You receive a sealed glass vial containing 10 mg PT-141 as a lyophilised powder. The label states the product name, content and batch number, so every vial can be matched clearly to the corresponding test report.

Orders are shipped in neutral, padded packaging. No instructions for human use are included, because the product is intended exclusively for laboratory research.

Quality: what matters when you buy PT-141

If you want to buy PT-141, look above all for traceable batch documentation. We publish available third-party test reports in our certificate of analysis library. There you can see which tests – such as HPLC for purity or mass spectrometry for identity – exist for the specific batch.

General substance data on PT-141 is also available in the free PubChem database of the US National Center for Biotechnology Information.

Laboratory storage

Lyophilised peptides are considerably more stable in dry form than in solution. For laboratory storage, −20 °C, dry and protected from light, is recommended. Room temperature for short periods, for example during shipping, is not critical.

Repeated freeze-thaw cycles should be avoided. Further handling follows your laboratory's requirements and standard operating procedures (SOPs).
