About the compound
What is PT-141?
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide and a melanocortin-receptor agonist derived from Melanotan II. It is the deaminated, ring-modified metabolite of that parent compound. Sova supplies PT-141 as a lyophilised research powder, CAS number 189691-06-3, with a molecular weight of 1025.18, catalogued as a laboratory reagent supplied for controlled research use within the melanocortin research area.
PT-141 acts as an agonist at melanocortin receptors, with research describing activity particularly at the MC3R and MC4R subtypes found in the central nervous system. Through these receptors the melanocortin system participates in signalling relevant to appetite, pigmentation and neural pathways. In the laboratory, PT-141 is used as a tool to probe melanocortin-receptor activation and downstream signalling under defined experimental conditions.
In the research literature, PT-141 is investigated within melanocortin-pathway studies and in research examining sexual-function mechanisms in animal and cellular models. These investigations focus on receptor pharmacology and central signalling rather than any applied use, and remain confined to controlled preclinical and laboratory settings. Sova provides the peptide solely to support such mechanistic and pharmacological research.
Every batch of PT-141 UK stock from Sova is verified by reverse-phase HPLC and ESI mass spectrometry, with results recorded on a batch-linked Certificate of Analysis. The lyophilised powder should be stored sealed, protected from light and kept frozen for long-term stability. Sova is a UK-based supplier dispatching domestically. This material is supplied strictly for laboratory research use only and not for human or veterinary use.

FAQ
PT-141, answered.
What is PT-141?
+
PT-141, or bremelanotide, is a synthetic cyclic heptapeptide and melanocortin-receptor agonist derived from Melanotan II. Supplied as a lyophilised research powder (CAS 189691-06-3, MW 1025.18), it is catalogued as a laboratory reagent for melanocortin research.
Is PT-141 legal to buy in the UK?
+
Yes. PT-141 is supplied in the UK as a laboratory research chemical for research use only. It is not a licensed medicine and is not sold for human or veterinary consumption. Purchasers are responsible for compliant handling within an appropriate research setting.
What is PT-141 studied for?
+
PT-141 is investigated in melanocortin-pathway research and in studies examining sexual-function mechanisms in animal and cellular models. This work focuses on receptor pharmacology and central signalling under controlled laboratory conditions, rather than any applied or human use.
How is Sova's PT-141 verified?
+
Each batch is analysed by reverse-phase HPLC to assess purity and by ESI mass spectrometry to confirm molecular identity. The results are documented on a batch-linked Certificate of Analysis supplied with the peptide, allowing laboratory verification against the stated compound.
How should PT-141 be stored?
+
Store the lyophilised powder sealed, protected from light and moisture, and kept frozen for long-term stability. Once reconstituted with a suitable solvent, keep it refrigerated and use within a short working period, handling under standard laboratory practice.
How is PT-141 related to Melanotan II?
+
PT-141 is a structural metabolite of Melanotan II, produced by deamination and modification of the ring structure. Both are melanocortin-receptor agonists, but PT-141 lacks the C-terminal amide of Melanotan II, giving it a distinct pharmacological profile studied in research.
