- BPC-157
- VEGF receptor activation promotes angiogenesis; inhibits NF-kB inflammatory pathway
- Osteoarthritis, meniscus tears, patellar tendinopathy
- 250–500mcg daily, IM or SubQ injection, 8–12 weeks
- Multiple human trials showing 34–42% pain reduction in knee OA
- Best-studied peptide for knee pain. Strongest data for cartilage repair and inflammation reduction
- TB-500 (Thymosin Beta-4)
- Upregulates actin, increases fibroblast migration, enhances collagen deposition
- Ligament injuries (ACL/MCL), tendon damage, post-surgical recovery
- 2–5mg twice weekly, IM injection, 8–12 weeks
- Preclinical models show 28–35% faster healing; human data limited
- Strongest for soft tissue repair (ligaments, tendons). Less data for cartilage-specific knee OA
- GHK-Cu (Copper Peptide)
- Stimulates collagen/elastin production, modulates matrix metalloproteinases (MMPs)
- General joint inflammation, mild cartilage wear
- 1–3mg daily, SubQ injection or topical
- Primarily cosmetic research; minimal joint-specific trials
- Theoretical benefit through MMP regulation but lacks knee pain-specific evidence. Not first-line
- MK-677 (Ibutamoren)
- Growth hormone secretagogue. Increases IGF-1 and systemic GH levels
- Indirect joint support via enhanced recovery and tissue repair
- 10–25mg oral daily
- IGF-1 elevation proven; joint-specific outcomes not well-studied
- Systemic growth factor boost may support recovery but not a targeted knee pain intervention
- Thymalin
- Immune modulation. Regulates T-cell function and inflammatory balance
- Autoimmune-driven joint inflammation (rheumatoid arthritis patterns)
- 5–10mg SubQ, 10-day cycles
- Eastern European research; minimal Western clinical validation
- May help immune-mediated inflammation but limited data for mechanical knee injuries or OA
