Research Use Only
PT-141 10mg (bremelanotide) is a synthetic cyclic heptapeptide that acts on melanocortin receptors, supplied in one pre-filled research pen. Every PT-141 pen is prepared to order in the UK and shipped cold chain by tracked delivery.
PT-141 is closely related to MT2 (Melanotan II): it shares MT2’s ring structure but ends in a free carboxylic acid instead of an amide. Our research compound guide covers other melanocortin peptides, including KPV.
How PT-141 is studied
PT-141 is an agonist mainly at the MC4R and MC3R melanocortin receptors, which are found in the hypothalamus and other brain regions. Research has focused on how central melanocortin signalling influences behaviour, using rodent behavioural models. It has also been developed elsewhere as a medicine, and reviews describe its clinical pharmacology.
5 key research areas
- MC4R and MC3R pharmacology. PT-141 is studied as an agonist at the central melanocortin receptors MC4R and MC3R.
- Central nervous system signalling. Studies examine how melanocortin pathways in the hypothalamus influence behaviour.
- Rodent behavioural models. Female rat studies examined the effect of melanocortin receptor activation on sexual behaviour.
- Structure-activity relationships. Its relationship to MT2 is used to compare how small structural changes affect receptor activity.
- Clinical development. Reviews summarise its development as a medicine elsewhere; this product is research material only.

What is PT-141?
PT-141, also called bremelanotide, is a synthetic cyclic peptide that acts mainly on the MC4R and MC3R melanocortin receptors in the brain. It has been studied in rodent behavioural models of central melanocortin signalling. Apexion supplies it for laboratory research only.
What is the difference between PT-141 and MT2?
PT-141 has the same ring structure as MT2 but ends in a free acid rather than an amide. MT2 is a broader melanocortin agonist also studied in pigmentation models, while PT-141 research focuses on central MC4R signalling.
How much PT-141 is in each pen?
Each pen contains 10 mg of PT-141 in one pre-filled research pen. Every pen comes from a single batch and carries its batch number.
Is PT-141 independently tested?
Every PT-141 pen is made fresh after your order is placed, so each one is prepared and quality checked to order rather than taken from old stock. Independent third-party testing of PT-141 is under way, and the batch Certificate of Analysis will be published as soon as the results are verified. Each pen carries a batch number, so its documentation can be traced.
Can PT-141 be used in humans or animals?
No. This product is not a medicine and is not licensed by the MHRA. It is supplied strictly for in-vitro laboratory research, and is not for human or veterinary use, diagnosis or treatment.
How should PT-141 be stored?
PT-141 is shipped cold chain. On arrival, keep the pen sealed and store it at −20 °C for long-term storage, away from heat and direct light. Handle it as little as possible and follow any batch-specific guidance supplied with your order.
