TB-500
Mechanism
Thymosin Beta-4 fragment that promotes cell migration, angiogenesis, and reduces inflammation systemically. Unlike BPC-157 which works locally, TB-500 travels through the bloodstream to reach injured tissue throughout the body.
Typical dose
2-5mg per week during loading, 2mg per week maintenance
Cycle length
4-6 week loading phase, then 2-4 week maintenance
Form
Injectable (subcutaneous or intramuscular)
Where to source it
The hard part with TB-500 isn't the protocol. It's finding a supplier that can prove what's in the vial. We assessed dozens against per-batch, third-party testing. A handful passed.
