Where to check prices
This site answers what a compound is and what the evidence says, and deliberately never answers which vendor to use or what to pay. This page is the honest version of the second question: where to compare prices, and how to read a price once you see one.
60 compounds with price pages · cost per milligram
The directory
Biohack Blueprint is a price directory run by this publication. It lists what vendors charge for the same compound, worked out to cost per milligram, so a comparison takes one page instead of eleven tabs. It carries price pages for 60 of the compounds covered here, and the compound cards on this site link straight to the matching page there.
It is a separate site, and its outbound links are affiliate links: buy through one and it can earn a commission, at no extra cost to you. That relationship is disclosed beside every link that carries it. No supplier pays for coverage or placement on either site, and the findings printed here are the same ones that would be printed without the links, including the unflattering ones.
How to read a price
Divide by the milligrams
The sticker is the least useful number on the page. A 40 dollar vial holding 10 mg costs less per milligram than a 25 dollar vial holding 5 mg. Every real comparison starts by dividing the price by the milligrams, which is the arithmetic the directory has already done for you.
Blends hide the arithmetic
A blend price cannot be divided into a per-compound cost, and that is often the point of selling one. Compare single compounds against single compounds, or you are comparing nothing.
A price only means something next to a certificate
The one published test of grey market semaglutide found purity between 7.7 and 14.37 percent against 99 on the label. A low price for powder that is not the compound is not a low price. The checks that catch the worst of it are in Guide 1, and reading the lab certificate itself is Guide 2. Both are free.
What this site still will not do
Recommend a vendor. The vendor table records what each vendor publishes about what is in the vial, including the ones that publish nothing, and deliberately ranks nobody. If you want the paperwork rather than the prices, start there. And once a vial is on the desk, the reconstitution calculator shows the mixing arithmetic step by step instead of hiding it.
