Oligopeptides are short chains of amino acids, typically comprising 2–20 residues. Their application in injury support or treatment is primarily based on their roles in wound healing and tissue repair. Scientific studies, particularly in vitro and animal research, have demonstrated that certain oligopeptides can promote cell migration, collagen synthesis, and angiogenesis—all essential processes in tissue regeneration following injury. For example, peptides like GHK-Cu and certain collagen-derived oligopeptides have been shown to accelerate wound healing and improve skin repair by stimulating fibroblast activity and modulating inflammation.

However, while these mechanisms are promising, clinical evidence in humans remains limited. Most clinical trials involving oligopeptides for injury or wound healing are small, preliminary, or focus on topical applications for skin wounds rather than deeper injuries such as muscle or ligament damage. There is a modest, but not robust, body of scientific literature supporting the use of certain oligopeptides in wound management, especially in dermatology and some surgical contexts. Nevertheless, the evidence is not yet strong enough (hence, a rating of 2/5) to recommend oligopeptides broadly for all types of injuries. More large-scale, high-quality clinical trials are needed to confirm their efficacy and safety in human injury repair.

In summary, while there is some scientific rationale and preliminary evidence for the use of oligopeptides in injury healing, robust clinical validation is still lacking.
