How to Complete Your Manual Payment
We accept manual bank transfers only — Zelle, PayPal, or on-chain Bitcoin. Nothing is charged automatically: you submit an order request, choose how you would like to pay, and your payment screen shows the exact amount and reference for that order. Follow the steps for the method you selected below.
Before You Send Any Payment
Pay the amount shown on your order's payment screen — it already reflects any volume discount and delivery.
Your order number is the reference we match payments with. Put it in the Zelle memo or PayPal note.
Transfers sent from a different name or account can be delayed while we confirm ownership of the payment.
Save your Zelle confirmation ID, PayPal transaction ID, or Bitcoin transaction hash until your order ships.
Pay by Zelle bank transfer
Zelle sends straight from your bank account to ours. Choose Zelle at checkout, then send the exact total to researchpeptide29@gmail.com.
- 01Open your bank's mobile app or online banking and choose Zelle.
- 02Send the exact total shown on your payment screen to researchpeptide29@gmail.com.
- 03Enter your order number in the memo field so we can match the transfer instantly.
- 04Return to your payment screen and submit your Zelle confirmation ID.
- 05We verify the transfer and email your dispatch timeline, usually within one business day.
Zelle transfers are irreversible once sent — double-check the recipient address and amount before confirming.
Enter your order number in the memo when your bank offers the field; it speeds up verification.
Pay by PayPal transfer
Send the payment to the PayPal account shown on your order's payment screen. Orders are held pending until we confirm receipt.
- 01Open PayPal and choose Send Money.
- 02Send the exact total shown on your payment screen to researchpeptide29@gmail.com.
- 03Enter your order number in the note field.
- 04Return to your payment screen and submit your PayPal transaction ID.
- 05We confirm receipt, complete qualification review, and email your dispatch timeline.
PayPal payments are irreversible once sent — confirm the recipient and amount before you send.
You can also scan the QR code on your payment screen to open the transfer pre-filled.
Pay on-chain with Bitcoin
Each Bitcoin order generates its own wallet address and exact BTC amount, so your payment is matched automatically.
- 01Select Bitcoin at checkout and submit your order request. A unique address and exact amount are generated for that order only.
- 02Scan the QR code with your wallet, or copy the address shown.
- 03Send the exact BTC amount displayed — not a rounded figure. That precise amount is how we identify your transaction.
- 04Keep the payment screen open. We watch the blockchain and confirm the order the moment the transaction is detected.
- 05Your order moves to qualification review and you receive a dispatch timeline by email.
Send only BTC from an on-chain wallet. Other assets sent to the address may be permanently lost.
Always use the address and amount from the current payment screen — each order gets its own address.
No transaction ID to report: on-chain payments are detected and matched automatically.
After You Send
- 01Payment matched
Bitcoin is detected automatically on-chain. Zelle and PayPal are confirmed once we verify the transfer, usually within one business day.
- 02Qualification review
Every order is reviewed against our research-use terms and purchaser attestations before dispatch.
- 03Dispatch
Approved orders ship cold-chain via FedEx or UPS, with tracking emailed to you.
