$4.06per mg landed
Every vendor's price per mg, side by side. Buy links may earn us a commission.
Also known as: TB-4, Thymosin Beta-4, Tβ4
TB-500 listings change often as vendors update batch IDs and pack sizes. Use the compare grid for landed cost per mg; your checkout total still wins because shipping and store promos vary by cart.
Why do rows disagree with the vendor PDP? Our snapshot can lag the vendor site for a little while. Refresh pulls newer rows when we have them.
Do you normalize salts and counter-ions? Not automatically. Listings are matched with peptide names and aliases; $/mg still uses the milligrams printed on that SKU until salt normalization ships.
Where does COA evidence land? Vendor profiles link out to COA files on their sites when badges are present.
