TB-500 price per mg

TB-500 for sale at 50 stores (95 listings), prices checked Nov 9, 2026. Lowest $1.03/mg, median $4.51/mg. Median for kits (5+ vials) $1.60/mg, for single vials $7.02/mg.

Also sold as: TB4, Thymosin beta-4, Thymosin beta-4 acetate. These are store labels, not a finding about what the vials hold; the FDA describes TB-500 as a fragment of thymosin beta-4.

A synthetic peptide sold under a common name rather than an official drug name. The FDA describes TB-500 as an acetylated fragment (amino acids 17 to 23) of thymosin beta-4, a naturally occurring 43-amino-acid protein. Many vendors label it as thymosin beta-4 itself, and the FDA has found different substances sold under the name, so check the listing. Products labelled as the 17-23 fragment, or whose own page describes it (Ac-LKKTETQ), are left out here. It is not an approved medicine in the US, EU or Canada. Status as of September 2026; status of every peptide.

Picks come from vendors with Finnrick lab tests and leave out listings the store marks out of stock; a listing that doesn't state its stock can be picked. The table below has every listing. A lab score describes the purity and dose of past samples. It doesn't mean a product is safe or suitable for any use.

One row per vial size with a listing that can be ordered: likely listing errors, prices far above other stores and listings the store marks out of stock are left out (a listing that doesn't state its stock counts). Stores: how many sell that size in any pack. A kit's price is for the whole pack. * Count assumed: the listing gives no vial count, so it is counted as 10 because it says "kit" or the store sells only 10-vial kits.

Wholesale and bulk: 10-vial kits. 25 stores sell TB-500 in kits of 5 or more vials, 24 of them in 10-vial kits. Lowest price per mg in a kit: 10 x 10 mg for $103.40 at peptideswholesaleusa.com ($10.34 a vial, $1.03/mg).

Ships to Canada: 17 of these 50 stores (their own shipping pages say Canada or worldwide). Ships from the US: 29 stores (a US warehouse or origin).

Which stores list TB-500: 50, cheapest per mg first

#: rank by price per mg among the listings shown; a sort by another column keeps each listing's rank. Score: Finnrick's TB-500 score at that vendor and its number of tests. "overall": Finnrick has no TB-500 score there, so the vendor's overall score is shown. vs median: 0.50x is half the median price per mg. Likely listing error: far below the normal range, or out of line with the store's own sizes. Size unclear: the listing's size is not stated, or its own page or store data gives a different one; treated like a likely listing error. Based in (Ships from column): the store's pages don't say where it ships from, so this is the location on the vendor's Finnrick profile. The "Ships from" filter counts it unless it ends in a question mark. * Count assumed: the listing gives no vial count, so it is counted as 10 because it says "kit" or the store sells only 10-vial kits. Sale, was: the store's own listing marks the price as reduced; "was" is its regular price. Shown only for 5% to 50% off, when the regular price per mg is no higher than the highest price per mg any store here asks for that peptide and pack type, this store included. A store that marks over 4 in 5 of its listings reduced gets no tag, and nor does a group of 5 or more single vials, or of packs, with over 4 in 5 marked (exact rule).
