Prices on record · October 2026Prices on record
We record listed prices as a fact about the storefront, not a recommendation. A price is a thing a company printed on a given day; it goes in the file next to the other things it printed, and it moves nothing in the seal.
Procedure. On 2026-10-19 the desk read 3,677 listings across 44 storefronts and kept, for each peptide, every single-vial listing at the two sizes the trade most commonly sells. For each size we enter the lowest listed price with the storefront that listed it, the median of all listings at that size, and how many listings that median rests on. Multi-vial packs, prefilled pens, capsules, sprays and sizes outside the two common ones are excluded from this table and remain in the dataset.
Prices are before coupons, as shown on the listing page. Storefronts pricing in GBP are converted to US dollars at a fixed approximate rate and marked; the storefront is the authority on the exact figure. A peptide name below is a label we normalised from the storefronts' own wording; coded listing names stay coded in the dataset and we do not expand them.
1,246 single-vial listings stand behind this table; the rest of the 3,677 read are in the dataset. A storefront named in the lowest column is named because of a number it printed, not because of anything in its file; open the report before reading anything else into it. Every storefront listed sells material labeled for laboratory research use only.
Reader questions
Answered from the fileIs the lowest price the supplier you should buy from?
The column says which storefront listed the lowest figure for that size on the day we read it. It says nothing about the paperwork behind the vial. The seal and the eight checks are on the verification report, which the supplier name links to; price carries zero weight in that seal.
Why only two sizes per peptide?
Because a price is only comparable at the same size. We fix the two sizes most storefronts list for each peptide and record every single-vial listing at exactly that size. Bulk packs, pens and odd sizes are in the dataset but not in this table.
What is the median, and why print it?
The middle listed price: half the storefronts we read list above it and half below. It tells a reader what the trade ordinarily charges without being pulled by one outlier at either end. The lowest figure alone would reward whoever misprices on a given day.
Do you convert foreign prices?
Yes, at a fixed approximate rate for GBP, so a storefront pricing in another currency can sit in the same column. The converted figure is marked. For the exact amount a buyer pays, the storefront is the authority.
