"vs market" compares the price per milligram with the code against the market for that peptide and vial size: the middle of other vendors' list prices, before any code of theirs. A negative number means it comes in below them. The typical price above is the middle of these comparisons across every single vial Oneday Compounds has in stock, and it reads near market when that middle is within 10% of the market either way. A vial size fewer than three other vendors have in stock has no market price. The market price can differ from the median on a peptide's own page, which counts every size at list price. Prices carry a sale when the vendor lists the sale price, and an offer that only appears in the cart, such as buy one get one free, is not counted. See the methodology for how prices are normalized.

10% comes off the cart subtotal, so what you save scales with what you buy rather than being a fixed amount. Across Oneday Compounds' current in-stock catalog that runs from $1.50 on their cheapest listing to $12.60 on Tirzepatide. The price list above shows the same arithmetic on their most popular peptides, and the vendor profile applies it to every listing.
PeptideScouter records one coupon code per vendor and does not track per-product exclusions. Vendors sometimes exclude sale items, bulk kits or bacteriostatic water without notice. The code itself was last verified at Oneday Compounds' checkout on November 7, 2026, though not against every product, so the prices on this page apply the full 10% to every listing - read them as the best case rather than a guarantee.
Not necessarily, and it varies by compound. With the 10% code applied, the typical peptide at Oneday Compounds comes in 35% below market, where the market is the middle of other vendors' list prices per milligram for the same peptide and vial size. For a specific peptide, the vendor comparison on that peptide's page applies each vendor's code and sorts by effective price.
