TB500 (TB4 / Thymosin Beta-4)
Thymosin beta-4 is studied in wound-healing contexts (preclinical + some clinical programs). 'TB500' in commerce is often loosely used; do not assume equivalence across products.
Save how you reacted, what dose worked, what to watch for, or anything you want to remember later in your Notes tab.
TB4 gel has been studied in venous stasis ulcer indications; registry evidence supports clinical testing, though effect sizes depend on the specific trial & endpoint reporting.
TB4 accelerated wound healing endpoints in a rat model compared with controls.
A review summarizes phase 2 wound-healing programs reporting faster healing in those that did heal; note that these are not sports injury RCTs.
Stacks containing TB500 (TB4 / Thymosin Beta-4)
Public community stacks that include this ingredient.
Adds a copper peptide often discussed in cosmetic/skin contexts to a recovery/joint pairing. Evidence is indirect & component-based.
BPC-157 & TB-500 are the two most researched recovery peptides, with complementary mechanisms. BPC-157 (Body Protection Compound) accelerates tendon, ligament, & gut repair via angiogenesis & growth factor upregulation. TB-500 (Thymosin Beta-4) promotes systemic tissue repair, reduces inflammation, & improves mobility. GHK-Cu supports collagen synthesis & skin regeneration. Note: all three are research compounds not approved for human therapeutic use.
Groups the two most commonly paired research peptides discussed in injury-repair circles; evidence is largely preclinical & not athlete-RCT grade.
