Tendon injuries initially suffer from: Poor blood supply Limited vascularity Slow nutrient delivery In rodent models, BPC-157 appears to: Upregulate VEGFR2 signalling Increase capillary density Improve microvascular perfusion Mechanistically: BPC-157 VEGFR2 activation PI3K/Akt pathway eNOS phosphorylation Increased nitric oxide Improved angiogenesis More vascularity = better nutrient and oxygen delivery to fibroblasts
Cytotoxicity profiling in vitro shows a dose-dependent pattern: cell viability holds within research-relevant concentration ranges but declines meaningfully above approximately 1 mM in culture, a threshold well outside the concentration windows described as biologically productive in the wound healing and gene expression literature
What the Literature Does and Does Not Support Available GHK-Cu Human Evidence Published human clinical trials on GHK-Cu are limited almost entirely to topical dermatology applications
