This source-based comparison does not add ratings or recommend a winner.

  • GHK-Cu peptide (subcutaneous or topical)
  • Collagen synthesis activation, NF-κB inhibition, copper delivery to cartilage
  • Preclinical (animal + in vitro studies only)
  • 4–8 weeks (subjective reports; not clinically validated)
  • $80–$150
  • Mechanistically plausible for cartilage repair but lacks human RCT data; consider as adjunctive only alongside proven treatments
  • NSAIDs (ibuprofen, naproxen)
  • COX enzyme inhibition reduces prostaglandin synthesis
  • High (multiple Phase 3 RCTs, decades of use)
  • 1–2 weeks
  • $8–$25
  • First-line therapy for OA pain management; 60–70% response rate but GI and CV risks limit long-term use
  • Intra-articular corticosteroids
  • Suppresses synovial inflammation via glucocorticoid receptor activation
  • High (systematic reviews + meta-analyses)
  • 3–7 days
  • $50–$100 per injection
  • Provides 4–12 weeks symptom relief; repeat injections may accelerate cartilage loss. Use sparingly
  • Hyaluronic acid injections
  • Viscosupplementation restores synovial fluid lubrication
  • Moderate (meta-analyses show modest benefit; some controversy)
  • 2–4 weeks
  • $200–$600 per series
  • Modest pain reduction vs placebo; benefits inconsistent across studies; insurance coverage varies
  • Physical therapy + exercise
  • Joint stabilization, muscle strengthening reduces abnormal loading
  • High (Cochrane reviews confirm efficacy)
  • 4–8 weeks
  • $100–$300 per month
  • Non-pharmacologic cornerstone of OA management; improves function without systemic side effects
