PT-141, also known as Bremelanotide, is a synthetic melanocortin receptor agonist derived from Melanotan II. It activates melanocortin receptors (MC1R and MC4R) and has been studied extensively in research models related to melanocortin receptor biology.
PT-141 is one of the most researched peptides in the sexual health and wellness research space. Unlike PDE5 inhibitors, it acts directly on the central melanocortin system. At AscendLabz, all PT-141 is for strictly laboratory and in-vitro research purposes only.

PT-141 (Bremelanotide) is a metabolite of Melanotan II, lacking the cyclic alpha-MSH component. PT-141 activates melanocortin receptors MC1R and MC4R. Both are research peptides derived from the melanocortin peptide family.
Our PT-141 is 99%+ purity, verified by HPLC/MS analysis. A Certificate of Analysis from a third-party laboratory is included free with every order.
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin agonist with MC3R and MC4R selectivity studied as part of the melanocortin receptor agonist category. It is investigated in pre-clinical and in-vitro research models for its activity on MC3R/MC4R-mediated central signaling pathways studied in vitro. The compound is supplied as a lyophilized powder of ≥99% HPLC-verified purity and is intended exclusively for laboratory research use under qualified scientific supervision.
AscendLabz PT-141 (Bremelanotide) is sourced from cGMP-aligned synthesis facilities and validated for identity, purity, and counter-ion content prior to release. Each lot is independently tested by HPLC, and a Certificate of Analysis (COA) detailing peak area, retention time, and batch number is provided with every order. This level of documentation is intended to support reproducible research and clear chain-of-custody record-keeping in academic and independent laboratory environments.
For research workflows, PT-141 (Bremelanotide) is most commonly characterized in cell-culture and isolated-tissue models where investigators examine MC3R/MC4R receptor agonism alongside complementary compounds in the melanocortin research peptides class. Reference standards and dose-response controls should be established by each laboratory prior to experimental use, and all material should be handled by trained personnel using appropriate personal protective equipment.
Storage: Lyophilized PT-141 is stable at -20°C protected from light. Reconstituted peptide should be refrigerated at 2-8°C and used within 30 days. Lyophilized peptides should be kept in original sealed packaging until use to prevent moisture uptake.
Reconstitution: Bring the lyophilized vial to room temperature before opening. Reconstitute with bacteriostatic water by injecting solvent down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Gently swirl — do not vortex or shake — until fully dissolved. Allow 5-10 minutes for complete solvation.
Handling: Use sterile technique throughout. Wipe vial septa with isopropyl alcohol before each draw. Document reconstitution date, solvent volume, and resulting concentration on the vial label for traceability.
Every batch of PT-141 (Bremelanotide) is analyzed by reverse-phase HPLC and confirmed to be ≥99% pure. Mass spectrometry confirms molecular identity, and counter-ion / residual-solvent panels are performed where applicable. The full Certificate of Analysis ships with each order and is also archived by lot number.
No. PT-141 (Bremelanotide) is supplied strictly for in-vitro laboratory research and is not approved by the FDA, EMA, or any regulatory authority for human or veterinary therapeutic use. It must not be administered to humans or animals. By purchasing, you confirm you are a qualified researcher and the material will be used only in a controlled laboratory setting.
All orders ship from the USA via tracked courier within 24-48 hours of payment confirmation. Domestic delivery typically arrives within 2-5 business days in discreet, temperature-stable packaging. Tracking is provided by email at the time of dispatch.
AscendLabz prices PT-141 (Bremelanotide) competitively while maintaining ≥99% HPLC-verified purity and a full COA. Bulk-vial bundles offer additional savings for laboratories ordering multi-month research supply. Pricing is reviewed monthly to remain among the most affordable verified-purity sources in the United States.
Cryptocurrency (Bitcoin, Ethereum, USDC, and others) is accepted with automatic discounts at checkout. Credit and debit cards are also supported through our secure payment processor. All transactions are encrypted end-to-end and order details are never shared with third parties.
Yes. Most laboratories order PT-141 (Bremelanotide) together with complementary compounds from the melanocortin research peptides category. Combined orders ship together with a single COA package and qualify for bulk-tier pricing. See the related compounds section below for commonly paired research peptides.
