Do bigger peptide vials cost less per mg?
Updated from live data. Research use only. Prices, not recommendations.
Yes, every time. On 29 of 29 peptides sold in more than one common vial size, the largest vial has a lower median price per mg than the smallest. The median saving is 46%.
The biggest difference is on NAD+: 5 mg vials sell for a median $13.00/mg and 1,000 mg vials for $0.109/mg, 99% less.

Median landed $/mg per vial size. The green dot marks the lower of the two.
No peptide gets dearer per mg in a bigger vial
Every peptide in the table is cheaper per mg, or level, in its largest common vial.
The cheapest listing is rarely the smallest vial
A small vial has a lower sticker price, which makes it look cheap on a store page. Per mg it usually is not. Compare pages sort by landed price per mg for this reason.
How we measured this
Every live, in-stock listing counts, priced as landed $/mg (list price plus any shipping estimate, minus the sale and sitewide code we show, divided by total mg). Listings are grouped by the mg in one vial, so a 10-vial pack of 5 mg sits with single 5 mg vials. A vial size needs listings from threeor more vendors to count, and a peptide needs two such sizes. Stacks are left out. Each size's median mixes different vendors, so part of a gap can be which stores sell which size.
No vendor pays for placement and none of these numbers is a ranking for sale. Buy links on the pages linked here may earn us a commission. More on how the site works on the about page.
