Ordering
Payment
Zelle, Cash App, Apple Pay and cryptocurrency. How each one works, what happens at each step, and how to tell a real payment instruction from a fake one.
Two kinds of payment, which work differently. Most are settled by hand and one is automatic, and the difference matters mainly for how quickly you get the details.
Zelle, Cash App and Apple Pay
Choose one at checkout and place your order. Nothing is charged on this site. Your order is recorded at pending payment and we email the instructions for the method you chose, usually within a few hours.
The details arrive by email rather than appearing on this page for a specific reason: a payment handle published on a public page is one anyone can copy into a fake storefront, or alter. Sending them after the order means they reach a confirmed address attached to a real order number.
Do not send any payment until our email arrives. We never send payment details before an order exists, never ask for payment through social media or chat apps, and never write from an address other than the one your order confirmation came from. Anyone who does is not us.
Cryptocurrency
The automatic route. The address and the exact amount appear the moment you place the order, the figure is locked for 30 minutes, and paying this way takes 2% off the order.
Why not cards
The card networks classify research compounds as a restricted category and will not underwrite merchant accounts for it. That is a decision by Visa and Mastercard, not by us, and it applies to every supplier in this sector without exception.
Any site in this category advertising card checkout is either processing through a misdescribed merchant account, which gets frozen without warning and takes customer orders down with it, or is not shipping what it claims to. Saying so plainly is more useful than a card logo that stops working in a month.
Apple Pay is listed as a payment-request option for the same reason: it runs on the card networks, so it is arranged by email rather than processed here. Choosing it tells us how you would prefer to settle, and we reply with what is actually possible.
What is accepted
| Coin | Code | Network |
|---|---|---|
| Bitcoin | BTC | Bitcoin |
| Ethereum | ETH | ERC-20 |
| Tether | USDT | TRC-20 |
| USD Coin | USDC | ERC-20 |
| Litecoin | LTC | Litecoin |
Stablecoins are the simplest. USDT and USDC track the dollar, so the amount you send is the amount on the invoice with no conversion to think about and no exposure to a market move.
The steps
- Fill in delivery details at checkout and pick a coin.
- An invoice is issued with an exact amount, a payment address and the network. The amount is locked for 30 minutes.
- Send that amount from your wallet or exchange to that address, on that network.
- Orders release once the network confirms, usually within minutes.
- The order enters the dispatch queue. Before 2pm ET on a working day, it leaves the same day.
A market move while you are sending is not your problem. The locked figure is what settles the order. If the window expires before your payment lands, you get a fresh invoice at the new rate rather than a shortfall to make up.
If something goes wrong
| Situation | What happens |
|---|---|
| Sent too little | A second invoice for the difference |
| Sent too much | Refunded or credited, your choice |
| Invoice expired mid-send | Fresh invoice at the new rate, payment still counts |
| Wrong network used | Usually recoverable. Email the transaction hash |
| Order lost or damaged | 30-day reship, unaffected by how you paid |
In every one of those cases the fix starts the same way: email Info@purepeptidesources.com with your order number and the transaction hash. A person replies within 24 hours.
Refunds
Refunds are sent in the same coin, to an address you supply, at the dollar value of the original order rather than the coin amount. If the market has moved since you paid, that movement is ours to absorb, not yours. The reship guarantee on lost or damaged orders works exactly as described there and is not changed by the payment method.
If you have never used cryptocurrency
The first time takes a day or two, because a regulated exchange account needs identity verification. After that, paying an invoice takes about a minute: open the exchange or wallet, paste the address, check the network matches, send the stated amount.
Start with a stablecoin. There is no conversion to work out and no market exposure between the invoice and the payment landing.
You pay with an ordinary debit or credit card — just at the exchange rather than here. The full walkthrough, written for someone who has never held cryptocurrency, is in how to pay with crypto: which coin to pick, what a network is, what it costs, and the mistakes worth avoiding.
Questions
What payment methods do you accept?
Zelle, Cash App, Apple Pay and cryptocurrency. With the manual methods you pick one at checkout and we email the instructions, usually within a few hours — nothing is charged on the site and nothing is owed until that email arrives. Cryptocurrency works differently: the address and locked amount are issued immediately, and paying that way takes 2% off.
Why do I have to wait for payment instructions?
Because these methods are settled by hand rather than through a processor. Sending the details after the order means they go to a confirmed address attached to a real order number, rather than sitting on a public page where anyone could copy or alter them. Until that email arrives your order is held at pending payment and you owe nothing.
Someone contacted me with payment details. Is that you?
Only if it came from our own address after you placed an order. We never send payment details before an order exists, never ask for payment through social media or chat apps, and never use a different address than the one your confirmation came from. If anything looks off, reply to your order confirmation and ask before sending anything.
Do you accept credit cards?
Not directly. Card networks classify research compounds as a restricted category and will not underwrite merchant accounts for it. That is a decision made by the card schemes, not by us, and it applies to every supplier in this sector. Apple Pay is offered as a payment-request option, arranged by email rather than processed on the site.
What happens if the price moves while I am sending?
It does not affect you. The invoice locks the exact amount for 30 minutes from the moment it is issued. If the market moves inside that window, the order still settles at the locked figure. If the window expires before the payment lands, a fresh invoice is issued at the new rate and you are not out of pocket.
Which coins are accepted?
Bitcoin (BTC), Ethereum (ETH), Tether (USDT), USD Coin (USDC), Litecoin (LTC). Stablecoins are the simplest choice because the amount you send is the amount in dollars, with no conversion to think about.
What if I send the wrong amount or use the wrong network?
Email the order number and the transaction hash. An underpayment is topped up with a second invoice for the difference, an overpayment is refunded or credited, whichever you prefer. A transfer sent on the wrong network can usually be recovered but not always, which is why each invoice states the network explicitly.
Can I get a refund in cryptocurrency?
Yes. Refunds are sent in the same coin to an address you supply, at the dollar value of the original order rather than the coin amount, so a change in the market between purchase and refund does not cost you. The 30-day reship guarantee is unaffected by any of this.
Do I need to buy cryptocurrency first?
If you do not already hold any, a regulated exchange account is the normal route and takes a day or two to set up the first time. After that, paying an invoice takes about a minute. Stablecoins are the least complicated place to start.
