Joint research
This hub covers compounds researched in models of knee, cartilage and joint injury or pain. The evidence is thin: findings come mainly from rats and rabbits, plus one small uncontrolled human report.
Limited human data
Animal and laboratory research
AOD-9604Preclinical research · Not approved — research use onlyIn a collagenase-induced rabbit knee osteoarthritis model, intra-articular AOD9604 was associated with lower cartilage-degeneration scores than saline; no controlled human trial.
BPC-157Preclinical research · Not approved — research use onlyA small retrospective chart review of knee-pain patients given intra-articular BPC-157 described improvement without a control group; a systematic review rated the human evidence very low certainty.

Questions people ask
Which peptides have been studied for knee pain in people?
Only BPC-157 has a human report: a retrospective chart review of 17 patients given intra-articular BPC-157, alone or with thymosin beta-4, without a control group. A systematic review judged the human studies of poor quality, with very low certainty of evidence.
Has Cartalax been studied in cartilage or joints?
No. Despite the cartilage connotation of the trade name, no study of this tripeptide in cartilage, chondrocytes or joint tissue was identified in PubMed; its literature is cell-culture and tissue-explant work.
Is there animal research on peptides in osteoarthritis?
In a collagenase-induced rabbit knee osteoarthritis model, intra-articular AOD-9604 was associated with lower cartilage-degeneration scores than saline. No controlled human trial of AOD-9604 was identified.
