TB-500
Recruits repair cells to injury sites and reduces scar tissue
Recruits repair cells to damaged tissue.
Avoid w/ cancer historyA synthetic fragment of thymosin-β4. Binds actin and organizes cytoskeleton assembly so stem cells and fibroblasts can migrate into wounds.
- Supports tendon, ligament, and muscle tissue remodeling.
- Systemic (not site-local) effect — circulates to multiple injuries at once.
- Often paired with BPC-157 in injury-recovery protocols.
TB-500 is a synthetic version of Thymosin Beta-4, a protein naturally present in most cells. It promotes cell migration to injured areas, helping repair cells reach damage faster. It's also been shown to reduce scar tissue formation, so healed muscle retains better flexibility.
How long it stays, how it leaves.
Fixed dosing — not weight-adjusted. The calculator handles reconstitution math for common vial sizes so you inject the right volume every time.
Three tiers, three goals.
Higher dose first 2 weeks, then lower
What people actually report.
- Head rush right after injection
- Feeling tired temporarily
- Irritation at injection spot
Before you start.
- Not FDA approved — research compound
- Avoid if you have cancer — it promotes cell growth
- Talk to a doctor before starting
Combinations worth knowing.
Injury Recovery Stack
TB-500 recruits repair cells throughout the body; BPC-157 supports local healing at the injury site. The most commonly paired healing stack.
