Best places to buy Retatrutide

Retatrutide is where the junk rate is worst. It’s the hottest compound on the gray market right now, which means every fly-by-night reseller wants to sell you a vial, and a depressing share of what’s floating around is underdosed, mislabeled, or bacteriostatic water with a confident label. So the bar here is not “cheapest per mg.” The bar is: recent third-party COAs on the actual batch you’re buying, a vendor that answers email, and a reship policy for when customs eats a pack.

Typical sizing runs 5 to 15 mg vials, with 10 mg the common middle. Bigger vials usually win the per-mg math, but only if you’ll actually finish them. A bargain 15 mg vial you toss after a bad reconstitution isn’t a bargain.

The leaderboard below sorts by price per mg because that’s the only honest way to compare. Read it with this in mind: I’d rather pay 20% more for batch-matched COAs and fast reshipping than win the spreadsheet and lose the vial. First order? Favor domestic shipping and card payments. Restocking a compound you already trust? Chase the per-mg number. Blends are priced per unit and sorted last, and mg-for-mg they’re not comparable, and I won’t pretend they are.
