TB-500 Best for: soft-tissue repair and wound-healing recovery TB-500 is the trade name for a synthetic peptide fragment (Ac-LKKTETQ, corresponding to amino acids 17-23 of the naturally occurring 43-amino-acid protein thymosin beta-4) marketed as an actin-regulating tissue-repair research compound
It is a substance occurring naturally in humans, where it is synthesized endogenously in the liver, kidneys, and brain
To help preserve peptide integrity during long-term storage, repeated freeze-thaw cycles should be minimized whenever possible
