"vs median" = how far below the middle-of-market price this vendor sits, so you can see where shopping around actually pays. Blends, bulk vials, out-of-stock, and non-injectable forms are excluded so "cheapest" means cheapest for the same thing. Prices are the vendor's list price; a discount code may lower checkout further.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). pepmg sells nothing, ships nothing, and gives no medical, dosing, or human-use guidance. Listings are price-tracking data, not endorsements.
