- BPC-157
- FAK-paxillin pathway activation → fibroblast migration + VEGF upregulation for angiogenesis
- 250–500mcg daily subcutaneous, localized injection near injury site, 4–6 week cycle
- Moderate. Animal models show 42% faster tendon healing; human data limited to case reports
- Tissue remodeling visible at 10–14 days; functional improvement 3–4 weeks
- First-line choice for active inflammation phase. Strongest evidence for collagen synthesis stimulation
- TB-500
- Thymosin Beta-4 fragment → actin regulation + cytokine downregulation (TNF-alpha, IL-1beta)
- Loading: 5mg 2×/week for 2 weeks; Maintenance: 2.5mg 2×/week for 4–6 weeks
- Moderate. Documented anti-inflammatory effects and reduced adhesion formation in joint injury models
- Anti-inflammatory effect within 7–10 days; structural remodeling 4–6 weeks
- Best for chronic tendinopathy with adhesion. Reduces fibrosis and improves range of motion
- Thymalin
- Thymus-derived peptide → immune modulation and tissue regeneration
- 5–10mg intramuscular or subcutaneous, daily or every other day, 10–20 day cycle
- Low. Primary research focused on immune function; musculoskeletal data minimal
- Immune modulation 5–7 days; tissue effects unclear
- Insufficient evidence for rotator cuff-specific application. Better suited for systemic recovery protocols
- MK 677 (Ibutamoren)
- Growth hormone secretagogue → IGF-1 elevation + sleep architecture improvement
- 12.5–25mg oral daily, minimum 8-week protocol for tissue effects
- Moderate. Proven GH/IGF-1 elevation; indirect tissue benefits through systemic anabolic environment
- IGF-1 elevation within 14 days; tissue remodeling 6–8 weeks
- Adjunct tool for overall recovery environment. Not targeted for rotator cuff; best used alongside localized peptides
