Frequently Asked Questions

Retatrutide (LY3437943) is an investigational peptide that acts on three receptors at once — GIP, GLP-1 and glucagon. It is the broadest incretin compound in the catalogue and one of the most heavily studied. Everything here is for research and educational purposes; what we sell is not intended for human use.
Two ways: PayPal or Bitcoin. PayPal is the quickest — pick it at checkout and pay as normal. For Bitcoin, we show you the wallet address; send the exact BTC equivalent of your total and we release the order once it confirms on-chain, usually after one to three confirmations. Never used Bitcoin? Cash App handles it in about five minutes — buy BTC in the app and send it straight to our address. There's a guide linked at checkout. Payment is for research-use purchases only.
We dispatch seven days a week. Order before 2 PM ET and it goes out the same day; later than that and it goes the next. Once it's moving, domestic delivery is normally three to five days. US shipping is free. International is a flat $20.
Yep. Order 3 or more vials and we throw in a 5 ml bac water for free — it lands in your cart automatically, no code needed. Under 3 vials? Grab one separately for $10.
