tb-500
HEALING · Tβ4 FRAGMENT · 7 AA
also: TB500 · Ac-LKKTETQ · thymosin beta-4 fragment
TB-500 is a seven-residue acetylated fragment corresponding to the actin-binding region of thymosin beta-4, originally popularised in veterinary and equine settings. Human clinical data exist for the full-length parent protein but not for this fragment, so its effects in people are unestablished.
// our evidence grade — unedited
TB-500 itself has no human trials at all; the phase 2 data people cite belong to full-length thymosin beta-4, a different 43-residue molecule, and TB-500 is WADA-prohibited and unapproved everywhere.
We grade this compound and we sell it. The grade is set against our published criteria before any stocking decision and is not adjusted because it is in the catalogue.
