Synthetic melanocortin receptor agonist studied for effects on neural pathways associated with sexual response in research applications.
PT-141 (bremelanotide) is a synthetic melanocortin-receptor agonist derived from the alpha-melanocyte-stimulating hormone (α-MSH) family. It is one of the most studied melanocortin-pathway research peptides outside of the tanning-active analogues. Quantum Labs supplies PT-141 as a lyophilised powder for Australian research applications.
Research on PT-141 has covered the central melanocortin pathway, particularly MC3R and MC4R receptor activation, and pre-clinical models of sexual-response signalling. Material is HPLC-verified to ≥99% purity and ships from Australian stock; supplied for laboratory research use only.
Research Mechanism
Research suggests primary agonism of MC4R with central nervous system effects on neurochemical markers in study subjects.
HPLC verified against a ≥99% purity specification. Independently tested by accredited third-party laboratories.
PT-141 — frequently asked questions
What is PT-141?
PT-141 (bremelanotide) is a synthetic melanocortin-receptor agonist studied in research models of central melanocortin-pathway signalling. It is one of the most-studied research peptides in the melanocortin family alongside the tanning-active analogues.
Is PT-141 legal in Australia?
PT-141 is restricted for compounded human therapeutic supply in Australia and remains available for research and laboratory use when supplied without therapeutic representation. Quantum Labs supplies PT-141 for research use only.
What receptors does PT-141 target?
PT-141 primarily activates the melanocortin-3 (MC3R) and melanocortin-4 (MC4R) receptors. Research has focused on the central melanocortin pathway, particularly downstream signalling in MC4R-rich brain regions.
What is bremelanotide?
Bremelanotide is the generic name for PT-141. It is a cyclic synthetic peptide derived from the α-MSH lineage. PT-141 is the research-code designation; bremelanotide is the pharmaceutical name.
What is the typical PT-141 research dosage?
Published research protocols have used wide dose ranges depending on the model and delivery route (intranasal, subcutaneous). Human dosing is not established. Researchers should consult primary literature for protocol-specific guidance.
