Documentation
Every PT-141 vial ships with a lot file.
COA, HPLC chromatogram, MS identity confirmation, water content and storage notes. We do not invoice without context — buyer track and destination are confirmed first.
MS identity
Mass spectrometry identity confirmation against the PT-141 reference mass profile.
Lot traceability
Lot code is printed on the vial label and reflected in the document pack. Reorders cite the prior lot for continuity.
FAQ
Common PT-141 questions from B2B buyers.
What is PT-141 used for in clinical and research contexts?
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist studied for neuroendocrine signaling pathways. Research labs and 503A compounding pharmacies source lyophilized PT-141 for protocol development and laboratory study.
What is your minimum order quantity?
Sample lots from 50 vials; production lots start at 200 vials with tier pricing. Repeat OEM orders are scheduled in 1,000-vial batches with locked packaging.
What documentation do you ship with each lot?
Every batch ships with a Certificate of Analysis showing HPLC purity, MS identity, water content, and lot traceability. HPLC and MS chromatograms are available on request as part of the document pack.
Can you do private-label PT-141 packaging?
Yes. Neutral or branded vial labels, carton design, document packs, and lot-code handling are available for repeat OEM supply. See the OEM service path for the full process.
How do you ship internationally?
Lyophilized PT-141 ships at controlled temperature with documentation. Destination country and buyer track are confirmed before shipment. We work with B2B and research buyers, not consumers.
