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.

What you read on the page is exactly what you get. No bait and switch, no weird substitutions, no missing items. They emailed updates at every step and the product looks and works exactly as advertised. I appreciate the transparency.
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.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
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.
Nothing dramatic to report — I ordered, it arrived quickly, the product is exactly what the listing said it would be. About three weeks in and I am seeing what I was hoping for. This is my new go-to supplier.
Von der Website über die Verpackung bis zum Produkt selbst — alles fühlt sich durchdacht an. Bestellung kam schneller als versprochen, gut geschützt, und die Dokumentation war komplett. Tut genau das, was ich erwartet habe.
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.
