About this compound
More on PT-141.
PT-141, also known as bremelanotide, is a synthetic cyclic peptide studied in laboratory research for its activity within the melanocortin receptor system. Supplied as a lyophilized powder, PT-141 is intended for controlled research investigating receptor signaling, neuroendocrine pathways, peptide stability, and related biological mechanisms.
Each vial contains 10 mg of lyophilized PT-141 and is supported by batch-specific analytical documentation. Independent testing provides researchers with useful information about the identity and purity of the material before it enters an experimental workflow.
While Melanotan II is frequently investigated in models involving melanogenesis and pigmentation, PT-141 is more commonly examined in neuroendocrine and central receptor signaling research. This distinction makes it useful as a reference compound when researchers are comparing different melanocortin-mediated pathways.
Research Applications
PT-141 has been investigated in research models involving:
Melanocortin receptor signaling
MC3R and MC4R activity
Neuroendocrine pathway research
Central nervous system receptor studies
Peptide stability and structural research
Comparative melanocortin pathway investigations
Research findings can depend substantially on the experimental model, receptor system, concentration, and study design. These applications should therefore be viewed as areas of investigation rather than therapeutic claims.

Independent Quality Testing
Research reproducibility depends on knowing the characteristics of the material being evaluated. Each lot undergoes independent analytical testing, including RP-HPLC with UV detection for purity assessment and appropriate identity and quantity verification.
Batch-specific documentation allows researchers to associate the material used in an experiment with its corresponding analytical results. This can be especially useful when maintaining laboratory records, comparing experimental batches, or reproducing previous work.
Rather than relying solely on a general product specification, researchers can review the documentation associated with the applicable lot.
Handling & Storage
PT-141 is supplied in lyophilized form and should be stored according to the applicable product documentation and established laboratory procedures. Protect unopened material from excessive heat, moisture, and direct light.
When preparing material for research, use appropriate laboratory procedures and validated handling practices. Minimize unnecessary mechanical agitation and repeated freeze-thaw exposure where applicable. Researchers should maintain suitable records for lot numbers, storage conditions, and experimental use.
Frequently Asked Questions
What is PT-141?
PT-141, or bremelanotide, is a synthetic cyclic peptide studied primarily in connection with melanocortin receptor and neuroendocrine research.
How much is supplied per vial?
Each vial contains 10 mg of lyophilized PT-141.
What is PT-141 studied for?
Research commonly examines PT-141 in relation to melanocortin receptor signaling, particularly MC3R and MC4R pathways, as well as broader neuroendocrine and central receptor research.
How is PT-141 different from Melanotan II?
Both are related melanocortin research peptides, but they are investigated for different biological endpoints. Melanotan II is strongly associated with pigmentation and melanogenesis research, while PT-141 is more commonly examined in neuroendocrine and receptor-signaling studies.
Is a Certificate of Analysis available?
Batch-specific analytical documentation is available for the applicable lot, providing researchers with information about testing and material characteristics.
Is PT-141 intended for human use?
No. This product is supplied strictly for laboratory and research purposes. It is not intended for human or veterinary administration, consumption, or therapeutic use.
Researchers can review the applicable batch documentation and retain the lot information with their laboratory records for improved traceability and experimental reproducibility.
