Research use only. DefinePeps supplies lyophilised peptides to verified researchers for in-vitro laboratory study. Nothing on this site is for human or veterinary use, and nothing here is medical advice.
How ordering works
A normal cart and checkout, paid in Bitcoin instead of by card. Four steps, no account needed.
1
Add compounds to your cart
Choose a strength and pack size on any compound. Single vials or 10-vial kits.
2
Confirm your research purpose
Checkout asks for your research purpose and a confirmation that the order is for in-vitro laboratory use.
3
Pay in Bitcoin
Checkout shows a BTC amount and QR code for that order, locked for 10 minutes. Send it from any wallet.
4
Shipped after confirmation
After one network confirmation your order ships within 24 hours with tracking.
Paying with Bitcoin
At the payment step, checkout shows a Bitcoin address generated for your order only, the BTC amount at the current exchange rate, and a QR code. The amount is locked for 10 minutes; send exactly what is shown from any wallet or exchange.
The page updates on its own once the network sees your transaction. Your order confirms after one block confirmation, usually within the hour, and ships within 24 hours of that.
We never publish a standing address. If anyone sends you an address that is not on your own checkout page, do not pay it.
Common questions
Sent slightly too much or too little? Overpayments are refunded to the sending address; underpayments are held until the balance arrives.
Timer ran out? Return to the cart and check out again; a fresh amount is generated.
New to Bitcoin? Any exchange account or self-custody wallet works. Buy the amount shown, paste the address, send.
Shipping costs are calculated at checkout by destination and weight; see the shipping page.
