Half of them. Four of eight blends cost less per mg than buying the same peptides as separate vials at the lowest prices we track. The median blend is 63% dearer than the separate vials.
The best case is Klow (GHK-Cu + BPC-157 + TB-500 + KPV): $0.25/mg as a blend at Chimera Peptides, against $0.57/mg for the parts.
The worst is Retatrutide + Cagrilintide, where the cheapest blend costs $6.67/mg and the parts $0.932/mg.

Landed $/mg of total peptide. The green dot marks the lower of the two.
Separate vials usually means more than one order
The separate price takes each component from whichever store is cheapest for it, so it often spans two or three stores. Each order carries its own shipping and minimums, and a blend arrives as one vial from one store. The gap has to be wide enough to cover that.
How we measured this
Blend price is the lowest live landed $/mg for the blend, per mg of total peptide in the vial. The separate price buys the same mg of each component at its own lowest live landed $/mg, from any vendor, and divides by the same total. Landed means list price plus any shipping estimate, minus the sale and sitewide code we show. Recipes are the standard mg per vial for each named blend; a store whose blend uses other amounts is still priced per mg.
