PT-141 (Bremelanotide) Research Peptide
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide related to melanocortin peptide analogues. It is used in research examining melanocortin-receptor pharmacology and central signalling, with notable activity at MC3R and MC4R.
PT-141 is a defined pharmacological compound, but this ZENTRA material is supplied only as a research reagent. Published clinical studies of licensed or developer-controlled material do not establish equivalence, sterility or suitability of a research vial.

Independent Batch Testing
Every current ZENTRA PT-141 batch is independently tested and records an HPLC purity result above 99%. Use the batch number printed on the product label to locate the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.
PT- 141 Research Context
Experimental work has used PT-141 to probe melanocortin signalling and centrally mediated behavioural responses. Human studies exist, but they evaluated controlled medicinal-development formulations and do not convert general research material into a medicine.
ZENTRA does not provide dosing, administration or therapeutic guidance. Researchers should distinguish receptor pharmacology from claims about outcomes in people.
Storage and Handling
Keep unopened lyophilised material at approximately -20°C for long-term storage or 2-8°C for short-term laboratory storage. Protect from light, moisture and repeated temperature changes.
PT- 141 Research FAQs
What is PT- 141?
PT-141 is bremelanotide, a synthetic cyclic melanocortin-receptor agonist peptide.
Is it the same as Melanotan II?
No. PT- 141 was developed from melanocortin analogue research but is a distinct compound with its own structure and receptor profile.
Which receptors are studied?
Research commonly focuses on MC3R and MC4R, while acknowledging broader melanocortin activity.
How is purity checked?
The current batch is independently tested by HPLC above 99% and linked to an online batch report.
Does this page provide a use protocol?
No. It describes published research and compound identity only.
Is it intended for human use?
No. ZENTRA PT- 141 is supplied strictly for laboratory research.
