TB-500 vs. BPC-157 vs. Growth Hormone Secretagogues: Recovery Mechanism Comparison
TB-500 (Thymosin Beta-4) Actin polymerization, VEGF upregulation, satellite cell recruitment Force production, range of motion, angiogenesis 2–10mg, 2–3x weekly, subcutaneous 2.5–3 hours (plasma); 48–72 hours (tissue-bound) Best for structural repair of mechan

- TB-500 (Thymosin Beta-4)
- Actin polymerization, VEGF upregulation, satellite cell recruitment
- Force production, range of motion, angiogenesis
- 2–10mg, 2–3x weekly, subcutaneous
- 2.5–3 hours (plasma); 48–72 hours (tissue-bound)
- Best for structural repair of mechanically damaged tissue; requires post-workout timing
- BPC-157
- GI tract healing, nitric oxide modulation, fibroblast migration
- Tendon/ligament tensile strength, gut permeability
- 250–500mcg daily, subcutaneous or oral
- 4–6 hours
- Broader tissue repair profile but slower; works synergistically with TB-500 in our Healing Total Recovery Bundle
- MK-677 (Ibutamoren)
- Growth hormone secretagogue receptor agonist; increases IGF-1 and GH
- Lean mass accrual, sleep architecture, nitrogen retention
- 10–25mg daily, oral
- Indirect recovery support via systemic anabolism; does not target acute tissue damage like TB-500
- GHRP-2
- Direct GH pulse stimulation
- GH peak amplitude, lipolysis
- 100–300mcg, 2–3x daily, subcutaneous
- 20–30 minutes
- Acute GH elevation but no direct tissue repair mechanism; available in our Body Recomp Bundle
- IGF-1 LR3
- Insulin-like growth factor receptor activation; myoblast differentiation
- Muscle protein synthesis, myonuclear accretion
- 20–80mcg, 3–5x weekly, subcutaneous
- 20–30 hours
- Long half-life allows systemic anabolism; works downstream of GH rather than at injury sites
