PT-141 10mg COA and lot verification
Each PT-141 10mg lot ships with a third-party Certificate of Analysis that lists the lot identifier, the reversed-phase HPLC purity result and the mass-spectrometry identity confirmation for that batch. Match the lot number printed on the vial to the lot on the COA before the material is used in any in-vitro protocol; if the two do not match, contact us for the correct document.
What is PT-141 10mg?
PT-141, also known as Bremelanotide, is a synthetic analog of α-MSH that activates melanocortin receptors (MC3R and MC4R) in the central nervous system. It is the only research peptide in its class FDA-approved (as Vyleesi) for hypoactive sexual desire disorder in premenopausal women.
PT-141 for sale at Amino Fuel Labs means a 10 mg vial of PT-141 (Bremelanotide) at 99.2% HPLC purity, independently verified by an independent third-party lab and dispatched same-day from a USA facility with a batch-specific Certificate of Analysis in the box. PT-141 is a melanocortin mc3r/mc4r agonist compound used in sexual-response, appetite, and cns melanocortin research. When researchers go looking for PT-141 for sale, the priorities are documented purity, batch-traceable third-party COAs, and reliable USA cold-chain shipping — and every vial we ship is engineered around those three guarantees.
How PT-141 works
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin agonist (active at MC3R and MC4R) that modulates central nervous-system pathways governing sexual response, appetite, and energy homeostasis in published in-vitro and animal research. This mechanistic profile is why PT-141 is one of the most-requested research compounds in the melanocortin mc3r/mc4r agonist category, and why purity verification matters so much — even small impurity differences can alter receptor-binding data in published in-vitro work.

Testing method
Reversed-phase HPLC with mass-spectrometry identity confirmation
Every lot of PT-141 we list is supplied with a lot-matched Certificate of Analysis. Identity is confirmed by mass spectrometry and purity is measured by reversed-phase HPLC, with both results reported for the specific lot printed on the vial label. The certificate travels with the order, so the documentation can be reconciled against the material on receipt. Purity is a lot-specific value: read the figure on the certificate that matches your vial rather than treating it as a fixed product attribute. Supplied for laboratory research use only.
PT-141 shipping and support
Orders placed before 2:00 PM ET ship the same business day from our USA facility. Standard delivery lands in 2–4 business days; expedited and priority options are available at checkout. Every order over $300 ships free, and we use insulated packaging with a cold pack for temperature-sensitive compounds. If anything arrives damaged or off-spec we replace it — no restocking fees, no upsell. Customer support is human-staffed and replies to research and order emails in under one hour during business days.
PT-141 10mg FAQ
What is PT-141 studied for?
PT-141 appears in laboratory research covering CNS research, melanocortin signaling studies, neuroscience. Every reference describes in-vitro or preclinical study models, not outcomes in people.
Does PT-141 include a Certificate of Analysis?
Yes. Each PT-141 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.2% purity by reversed-phase HPLC with mass-spectrometry identity confirmation. The COA linked on this page matches the lot number printed on the vial.
What form does PT-141 arrive in and how is it stored?
PT-141 is supplied as lyophilized powder in a sealed vial with its lot documentation. Store at -20°C (Freezer), protect the vial from light and avoid repeated freeze–thaw cycles.
Does HPLC purity tell me the net peptide content?
No. HPLC area-percent purity and net peptide content are different measurements. Review the report for each value rather than treating them as interchangeable. Read about peptide purity versus net content.
What purity is your PT-141 for sale?
Every batch of PT-141 for sale at Amino Fuel Labs is independently HPLC-verified at 99.2% purity with mass-spectrometry identity confirmation by an independent third-party lab.
What size is the PT-141 vial?
Our standard PT-141 for sale is a single 10 mg lyophilized vial. The vial ships in an insulated mailer with a cold pack by default.
How fast does PT-141 ship?
All PT-141 orders ship same-day from our USA fulfillment center on orders placed before 2:00 PM ET, Monday through Friday. Standard delivery is 2–4 business days.
What is PT-141 used for in research?
PT-141 (Bremelanotide) is researched for its effects on sexual desire and arousal via central melanocortin receptor activation, in contrast to vascular-targeted compounds.
How is PT-141 different from Viagra?
PT-141 acts on the central nervous system (MC4R in the hypothalamus). Viagra/Cialis are PDE5 inhibitors that work on vascular blood flow. They target different stages of sexual response.
Is your PT-141 third-party tested?
Yes. Every vial ships with HPLC and Mass Spec verification at ≥99.2% purity and an itemized Certificate of Analysis.
