TB-500 (Thymosin Beta-4) is unique among recovery peptides in that it uses a two-phase protocol — a higher-dose loading phase to saturate tissue and drive acute repair, followed by a lower-dose maintenance phase. Understanding this distinction is critical to using TB-500 effectively.
Phase 1: Loading Protocol (Weeks 1–6)
The loading phase is used for acute injuries or when beginning a new TB-500 cycle. The goal is to rapidly elevate systemic Thymosin Beta-4 levels to drive tissue repair.
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading | 2–2.5mg | 2x/week | 4–6 weeks |
| Maintenance | 2mg | 1x/week | Ongoing |
TB-500 + BPC-157 Stack
The most powerful recovery stack combines TB-500's systemic actin-sequestration and cell migration effects with BPC-157's localized angiogenesis and growth factor modulation. Run both simultaneously: TB-500 at loading dose 2x/week + BPC-157 at 500mcg 2x/day near the injury site. This combination addresses both the systemic and local components of tissue repair simultaneously.
Reconstitution
TB-500 is typically supplied in 5mg vials. Add 2mL BAC water = 2,500mcg/mL. For a 2mg dose, draw 0.8mL (80 IU). For a 2.5mg dose, draw 1mL (100 IU). TB-500 is stable for 4–6 weeks refrigerated post-reconstitution.
