Klarna vs. Afterpay for Peptide Purchases
PSPeptides accepts both Klarna and Afterpay, so you can choose whichever service you prefer. For most peptide orders, the two are functionally identical: both split your purchase into 4 interest-free payments every two weeks, both ship your order immediately, and both use only a soft credit check. The main difference is that Klarna also offers monthly financing for larger research orders. If you already have an account with one service, simply use that one.
