PS Peptides and 99 Purity Peptides each list a verified 10% code, rechecked November 2, 2026. PS Peptides uses NOW10OFF; 99 Purity Peptides uses PPEPTIDESPC10. The percentages match, but the evidence we inspected is different. PS Peptides links several kinds of batch reports on product pages. The 99 Purity Peptides Certificates page posts Eagle Analytical sterility and endotoxin reports. Neither report set should be treated as a blanket test of every vial.

PPEPTIDESPC10, 10% off store-wide |

Which code saves more?
At the same eligible subtotal, 10% is 10% at either store. Your real decision depends on the price of the same compound and strength, quantity pricing, shipping and the reports for its batch. In our September 25 PS Peptides test, four BPC-157 5mg vials received the bundle price and then the code. That does not establish today’s price at either supplier or prove that 99 Purity Peptides lacks other offers.
Which testing matters for your purchase?
For PS Peptides, the product pages we inspected link purity, content, heavy metals, endotoxin and sterility results. For 99 Purity Peptides, the Certificates page we reviewed emphasized sterility and endotoxin from Eagle Analytical. Open the certificate for the specific lot and check the listed methods and results. A page that shows one type of test does not imply the other types were performed.
