PT-141
PT-141 is a high-purity research compound supplied as a lyophilized powder in a sealed, sterile glass vial. PT-141 (Bremelanotide) is a melanocortin 4 receptor (MC4R) agonist studied in preclinical models for its role in central nervous system pathways associated with sexual arousal signaling. Manufactured using solid-phase peptide synthesis (SPPS) and purified via preparative HPLC to ≥99% purity, with identity confirmed by LC-MS. Reconstitute with sterile bacteriostatic water before use. Store lyophilized vials at -20°C for long-term storage or 2-8°C for short-term. For laboratory and research use only. Not for human or veterinary use.
Product Details
PT-141 is synthesized using advanced solid-phase peptide synthesis (SPPS) technology and purified to ≥99% via preparative HPLC. Each vial contains lyophilized peptide verified by electrospray ionization mass spectrometry (ESI-MS) for exact molecular mass confirmation. The lyophilization process is performed under inert nitrogen atmosphere to prevent oxidation and ensure maximum shelf stability. Reconstitute with bacteriostatic water for optimal peptide preservation. Store reconstituted solutions at 2-8°C and use within 30 days.
Research Focus & Mechanism Overview
PT-141 (Bremelanotide) is a melanocortin 4 receptor (MC4R) agonist studied in preclinical models for its role in central nervous system pathways associated with sexual arousal signaling. Researchers should note the compound's stability profile under various buffer conditions when designing experimental protocols. Recommended for use in comparative pharmacological profiling, receptor binding assays, dose-response characterization, and mechanistic pathway studies.

FREQUENTLY ASKED
QUESTIONS
How should I reconstitute PT-141?
Slowly inject bacteriostatic water along the inside wall of the vial to avoid foaming. Do not shake — gently swirl until the powder is fully dissolved. Use sterile technique throughout. Store reconstituted solution refrigerated at 2-8°C and use within 30 days.
What purity is guaranteed for PT-141?
Every batch is tested in-house via HPLC and independently verified by third-party LC-MS analysis. We guarantee a minimum purity of ≥99%. Certificates of Analysis (COA) are available for download on each product page.
How should I store PT-141?
Store lyophilized (unreconstituted) vials at -20°C for long-term storage or 2-8°C for short-term. Protect from light and moisture. Reconstituted peptide should be kept refrigerated at 2-8°C and used within 30 days. Avoid repeated freeze-thaw cycles.
Is this product approved for human use?
No. All Sparta Labs products are strictly intended for in-vitro laboratory research only. They are not drugs, supplements, or food products. Not approved by the FDA or any regulatory body for human or veterinary use.
