Full unboxing video below.
Peptira rolled out new labels and they look sharp. Before we get into the sale details, watch the unboxing:
The Sale
Payment processing has been a mess across the research space lately. The pattern is the same everywhere: a vendor adds a new processor, it works for a few days, and then the processor holds the funds and shuts them down. These companies aren’t choosing the difficult path — they’re being forced into it by processors that won’t work with them reliably.
Peptira is getting ahead of this by rolling out two bank-based payment options with real savings attached. I’ve personally used both for my own RS purchases, and this is likely the direction you’ll see more vendors heading.
Current discounts
Zelle — 10% auto + 10% with code DEREK = 20% total
E-Debit / Plaid — 20% auto + 10% with code DEREK = 30% total
Comparing prices in real time
I added two toggle buttons directly above the pricing on Peptide Price — one for ACH, one for Zelle. Toggle either one and the prices automatically adjust to reflect the discounted rate, so you can see Peptira’s actual out-of-pocket cost against every other vendor at the same time. If another vendor is still cheaper after the discount, the rankings will show it. That’s the point.
Full walkthrough: 
The 30% total with e-debit is real money on a meaningful order. If reliable card processing existed, vendors would use it — this isn’t a preference, it’s a necessity. Expect it to become more common across the space. Peptira is one of the first to build the discount incentive around it.
All orders also get you entered into the Build-A-Kit giveaway (3 remaining).
