PS Peptides and Peptime both list a 10% code, rechecked November 2, 2026: NOW10OFF and PPTXKW10, respectively. The meaningful distinction is what happens as quantity grows and what their certificates cover. PS Peptides’ code stacked with its 3% or 5% bundle price in our BPC-157 test. Peptime lists automatic same-product tiers up to 20% at ten units, but we have not tested whether its code combines with those tiers.

Which is better for a large order?
Peptime’s published tier reaches 20% at ten units of one product, a larger listed quantity percentage than PS Peptides’ 5% bundle price. Do not add Peptime’s 10% code to that 20% until both reductions appear in your cart; we have not verified stacking. At PS Peptides, we did verify NOW10OFF after the bundle price in a September 2026 four-vial cart. Prices and product strengths still need a like-for-like comparison.
What do the certificates show?
The two Peptime certificates we opened came from Freedom Diagnostics and reported identity, HPLC purity and net content. Neither included endotoxin or sterility. The PS Peptides pages we inspected linked those safety panels as separate reports, alongside purity and content. Check the certificate for the lot you would receive; a homepage testing claim is not the same as a lot-specific result.
