PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of α-MSH that acts primarily at melanocortin receptors MC3R and MC4R. Research models show it modulates central signaling pathways associated with pigmentation, appetite regulation, and autonomic response — distinct from peripherally-acting peptides. Initial development was for sunless tanning; later research focused on CNS-mediated endpoints.
For the 10mg vial: reconstitute with 2mL bacteriostatic water → 5 mg/mL. On a U-100 insulin syringe, 10 IU = 0.1 mL = 500 mcg. For nasal spray presentations the device is pre-calibrated — follow the included dosing card.

Three curated paths into the research literature on this compound.
Based on 123 verified researcher orders.
Had a question about storage before I opened the vial and got a real, helpful answer within a few hours, not a copy-paste reply. Order itself arrived in four days, double-boxed, with the certificate of analysis tucked inside. Quality has been excellent so far.
มีคำถามเรื่องการเก็บรักษาก่อนเปิดขวด ได้คำตอบที่เป็นประโยชน์จริงในไม่กี่ชั่วโมง ไม่ใช่ข้อความสำเร็จรูป พัสดุมาถึงในสี่วัน บรรจุสองชั้น มีใบรับรองอยู่ข้างใน คุณภาพถึงตอนนี้ดีมาก
J'ai testé plusieurs fournisseurs cette année et la différence ici est nette. Le certificat correspond bien au lot, le flacon a la bonne allure, on voit tout de suite que c'est du sérieux. La livraison a été un peu plus longue que d'autres mais ça vaut largement l'attente.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
