Frequently Asked Questions
What is PT-141 peptide?
PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist, studied for its activity at MC4R pathways involved in central nervous system signalling research. Peptalix Labs supplies PT-141 10mg at 99.862% purity, confirmed by Freedom Diagnostics.
What purity is Peptalix Labs PT-141 10mg?
Independently batch-tested at 99.862% purity by Freedom Diagnostics using HPLC with UV detection coupled with mass spectrometry. Net peptide content 8.58mg per vial, Lot 112-U, COA #2604100042, reported 04/12/2026.
What is the difference between PT-141 and Melanotan II?
Both are melanocortin receptor agonists, but PT-141 (Bremelanotide) is a metabolite of Melanotan II studied with a more selective MC4R activity profile, while Melanotan II activates a broader range of melanocortin receptors.
How is PT-141 peptide stored?
Supplied as white lyophilised powder. Store the sealed vial at -20C prior to reconstitution. Once reconstituted with bacteriostatic water, store at 2-8C and use within 28 days.
How do I reconstitute PT-141 10mg?
Draw the desired volume of sterile bacteriostatic water into a fresh syringe and inject slowly down the inner wall of the vial. Gently swirl until fully dissolved. Never shake.
What research has been published on PT-141?
PT-141 has been studied in melanocortin receptor research, particularly examining MC4R-mediated central nervous system signalling pathways.
Can I buy PT-141 peptide online in the USA?
Yes. Peptalix Labs offers PT-141 10mg for purchase online for qualified USA researchers. COA-verified at 99.862% purity, GMP-sourced, same-day shipping.
Does Peptalix Labs ship PT-141 internationally?
Yes, to Canada, Australia, the United Kingdom and most of Europe, with tracked delivery in 5-12 business days.
What is PT-141 peptide nasal spray?
PT-141 nasal spray refers to an aqueous intranasal formulation studied in some research settings. Peptalix Labs supplies PT-141 10mg in lyophilised powder form for researchers to reconstitute per their own protocol.
What is the appearance of PT-141 10mg?
White lyophilised freeze-dried powder, as confirmed in the Freedom Diagnostics COA (Lot 112-U).
Is PT-141 peptide legal to buy in the USA?
Yes, as a research chemical for qualified researchers conducting in-vitro laboratory studies. Not FDA-approved for human use. Sold strictly for research purposes.
What is the research dosage range for PT-141?
Published PT-141 research has used varying dosing parameters depending on study model. Peptalix Labs does not provide dosing guidance, as our products are sold for research use only.
Which lab verified Peptalix Labs PT-141 purity?
Freedom Diagnostics, a US-based independent laboratory operated by Principal Chemist Alex Johnson. COA #2604100042, reported 04/12/2026.
Can PT-141 be studied alongside Kisspeptin or Oxytocin?
Yes. PT-141, Kisspeptin, and Oxytocin are all studied within broader neuropeptide and reproductive-signalling research panels, though each acts through distinct receptor mechanisms.
What other research peptides does Peptalix Labs offer in this category?
Our vitality category includes Kisspeptin-10, Oxytocin, and VIP — all COA-verified and GMP-sourced.
