How to Use TB-500
Complete guide to TB-500 dosing, administration, timing, and protocol recommendations.
Quick Overview
TB-500 is a synthetic peptide that copies the active region of thymosin beta-4, a natural protein that controls how cells build and move their internal skeleton. Most TB-500 products reproduce the short LKKTETQ sequence (residues 17 to 23) responsible for binding actin and driving cell migration, which is why it gets marketed for tendon, muscle, and wound repair. Here is the honest part: there are essentially no completed human trials of the TB-500 fragment itself, and almost all the human clinical data is for the full-length thymosin beta-4 molecule, which is related but not the same thing.
Dosing Guidelines
Common Dose
2-2.5 mg twice weekly (loading), then 2.5 mg once weekly (maintenance)
Frequency
2x weekly for 4-6 weeks, then 1x weekly
Dose Range
2-10 mg per week during loading phase
Note: Loading phase builds up tissue levels. Maintenance phase sustains benefits. Often stacked with BPC-157 for injury recovery.
Administration Method
Subcutaneous or intramuscular injection
Best Time to Take
Morning or evening
TB-500 has a long half-life, so timing is flexible. Consistency matters more than specific time of day.
Protocol Duration
4-6 weeks loading, then maintenance
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Generally well-tolerated in preclinical studies
- •Injection site reactions
- •Headache
- •Fatigue
- •Nausea
