How is cost-per-mg calculated?

We divide landed list price plus our recorded shipping estimate by the labeled milligrams on the SKU. Sitewide coupons are applied once we can attribute them per vendor in data. Always verify at checkout.

Do you sell peptides?

No. pep.deals is an independent comparison tool linking to third-party suppliers. We do not sell, ship, or support any product.

Is this medical advice?

No. Catalog items are discussed strictly as research-use-only chemicals. No dosing or use guidance is provided.

Bench-grade framing only: TB-500 SKUs move weekly as vendors rotate batch IDs and fill weights. Use the compare grid for landed cost per mg; checkout totals still win because carriers and coupon stacks vary.

FAQ

Why do rows disagree with the vendor PDP? Captures lag automated scrapes by minutes to hours; refresh triggers a focused pull.

Do you normalize salts and counter-ions? Not yet. Stick to the vendor label for mass basis until aliases graduate from admin review.

Where does COA evidence land? Vendor profile badges deep-link to files we could verify; stale labs drop the recency flag automatically.
