Buy PT-141 Wholesale — 10-Vial Kit Pricing, COA & Low Minimums

2026-06-19 · 6 min read

PT-141 is stocked in ten-vial kits with per-vial wholesale pricing, a third-party certificate of analysis on every lot, and a one-kit minimum. This guide covers what the compound is, what a kit actually costs at each volume tier, and how documentation is handled.

What PT-141 is

PT-141 is a cyclic heptapeptide metabolite of Melanotan II with a shifted receptor profile favouring MC4R and MC1R, studied for centrally mediated signalling rather than pigmentation.

Research-grade PT-141 (bremelanotide), a melanocortin receptor agonist, supplied lyophilized with lot documentation.

Wholesale kit pricing for PT-141

A 10 mg vial lists at $28.00, so a sealed 10-vial kit lands at $280.00. At the ten-kit tier the same vial drops to $22.40 and 100 vials cost $2240.00.

Volume tiers apply per SKU and stack across the catalog: 1 kit at list, 2 kits at 5% off, 3 kits at 7% off, 5 kits at 12% off, and 10 kits at 20% off. Because our minimum is a single ten-vial kit rather than a pallet, a lab can validate one lot before committing capital to a larger position.

Available fills: 10 mg. Mixed-size orders are fine — the discount tier is calculated on total kits, not on a single dose.

Documentation and testing

Each PT-141 lot ships with purity by HPLC and identity by mass spectrometry from a third-party laboratory. The COA carries the lot number printed on the vial, so a receiving lab can reconcile paperwork to physical stock without contacting us.

If you need the COA before you buy, request it against the lot currently in stock and we will send the exact document that will accompany the shipment.

Handling and storage

Store lyophilized vials at -20°C or below, protected from light. Hold reconstituted material at 2-8°C and use it inside the window your protocol defines.

Kits ship in insulated packaging. Domestic orders received by 2PM PT dispatch the same business day, and freight is free above $2,500.

Who buys PT-141 by the kit

mc4r signalling — Reference agonist for central melanocortin pathway assays; neurobehavioural models — Applied to CNS-mediated response endpoints; comparative pharmacology — Benchmarked against Melanotan II to separate receptor contributions

Buyers fall into three groups: university and contract laboratories running assay work, formulation groups building reference libraries, and research brands that need consistent US-made supply behind their own label.
