Drexa Labs has the larger listed code: PEPTIDESPROM15 gives 15% off, versus NOW10OFF at PS Peptides for 10%. Both were rechecked on November 2, 2026. Each code stacked with its store’s quantity pricing in our earlier cart tests, so the useful comparison is the final price for the same product and strength. PS Peptides has broader published report coverage in the products we inspected; Drexa’s smaller report set is independently verifiable at ILS Laboratories.

Is Drexa cheaper after discounts?
The 15% code can remove more from an equal eligible subtotal. But the underlying vial prices and shipping matter more than the percentage alone. Our September 2026 Drexa test took $5.25 off a $35 BPC-157 10mg vial, before $14 shipping below its threshold. Our PS Peptides test used a different vial size, BPC-157 5mg, so its $44.99 discounted price is not a like-for-like comparison. Build equal carts before deciding.
Which lab records can you check?
We entered Drexa’s six published ILS access codes into the lab’s portal and matched the results. At the time, only four of 47 products had a report; the others did not claim a published purity figure. PS Peptides’ product pages linked purity, content, heavy-metal, endotoxin and sterility reports on the batches we reviewed. Its North American Diagnostics reports we checked matched the lab records. Verify the lot for either supplier.
