Peptides for joints & tendons

Joint and tendon claims range from collagen supplements for osteoarthritis to injected BPC-157 for injuries. The human evidence is stronger for the first than the second, but neither is clear-cut.

What the evidence shows

Oral collagen for osteoarthritis symptoms

Mixed human results

A meta-analysis of randomised trials found lower total WOMAC scores and pain scores than placebo, but no significant difference in the WOMAC pain and function subscores.

BPC-157 for tendon, ligament and joint problems

Mostly animal evidence

A systematic review found 35 animal studies and 1 clinical report. The human data amount to small pilots and a retrospective chart review of 16 patients with no control group.

Tewari et al., 2026 · Am J Sports Med · Published animal and human studies of six peptides for musculoskeletal recovery

Of the publications found, 67% used animal models. Human studies were a handful, mostly without robust controls, and showed modest improvements at best for metabolic bone health and degenerative knee pain. The authors conclude that the claimed benefits for…

Vasireddi et al., 2025 · HSS J · 36 studies: 35 preclinical (animal) and 1 clinical, from 1993 to June 2024

Nearly all the evidence on BPC-157 is from animals. Those studies suggest faster healing of muscle, tendon, ligament and bone injuries. The one clinical report was a retrospective study of knee injections in which 7 of 12 patients reported relief lasting…

Effect of collagen supplementation on osteoarthritis symptoms: a meta-analysis of randomized placebo-controlled trials

García-Coronado et al., 2019 · Int Orthop · Randomised placebo-controlled trials of oral collagen in osteoarthritis (number of trials not given in the abstract)

Collagen lowered the total WOMAC osteoarthritis score (weighted mean difference −8.00; 95% CI −13.04 to −2.95) and the pain visual analogue scale (−16.57; 95% CI −26.24 to −6.89) compared with placebo. Within WOMAC, the stiffness subscore improved.
