Totals come from the same optimizer as our comparison tool: each vendor's cheapest way to supply the amount, with its multi-vial and mix-and-match discounts, the discount codes we hold for that vendor, and shipping to the US. Vendors reach each amount with whatever vial sizes they sell, and a vendor without a matching size may ship slightly more. Codes marked "first order only" assume a first order. "Per mg" is for the 800mg total. Confirm the final price at checkout. *Testing marked with an asterisk is present on some batches, not all.

|---|---|---|---|---|
| 80mg | 12 | $67 · Proved Peptides | $405 · PeptidePlugs | $0.506 |
Each strength is priced using only that vial size (single vials or packs of it), the same as choosing that size in the comparison tool. Totals include multi-vial discounts, our discount codes and US shipping.
It depends on how much you buy, because most vendors discount multi-vial orders. For 80mg, Proved Peptides is lowest at $67 total. For 800mg, PeptidePlugs is lowest at $405 total ($0.506 per mg), including code PLUG (10% off, first order only) and free shipping.
