PT-141

PT-141 (bremelanotide) is a cyclic melanocortin-receptor agonist peptide used as a research compound in melanocortin and receptor-signaling studies. It is sold for laboratory and research use only.

PT-141 (bremelanotide) is a metabolite of Melanotan II, and the two are frequently studied in parallel as melanocortin-pathway reference compounds. PT-141 is supplied as a 10 mg lyophilized vial; Melanotan II is stocked separately in the same size, so a side-by-side comparison can be sourced from one batch series.

No. Every product is sold strictly for laboratory and research use only. It is not for human consumption and not for diagnostic or therapeutic use.

Yes — bulk is the only way we sell. Product ships in kits of 10 vials, and the minimum order is 100 vials (10 kits) mixed across any compounds you like. We are structured for labs, clinics, and distributors buying at volume rather than for single-vial retail purchases.

Yes. Our peptides are sourced by our own US-based team and held in US inventory, so every order ships domestically — no overseas fulfillment or international transit delays.

Standard orders ship within 24 hours of payment. Everything dispatches from inventory inside the United States with tracking provided — because we ship domestically, transit is days, not the weeks international orders can take.

Yes. A third-party COA is available for any batch for an additional $75 per line item. Add it to the line when you build your quote and we attach it to your order.

Pricing is tiered by total order volume, not by line. The minimum order is 100 vials (10 kits). Once a single order reaches 1,000 vials (100 kits), every line on that order moves to the wholesale price — so consolidating compounds into one larger order is almost always cheaper than splitting it across several.

Each batch is tested by third-party HPLC for identity and purity. Typical purity is at or above 99%.
