The nearly painless self-injection process uses a unique self-injection device
[1] At the cellular level, the tendon work is genuinely mechanistic: in cultured rat tendon fibroblasts, BPC-157 accelerated cell outgrowth, improved survival under oxidative stress, and increased migration in a dose-dependent way, apparently through the FAKpaxillin pathway
Basically, MMP-9 in an overly simplistic way is an enzyme that gets activated when there's a lot of tissue repair: tissue gets damaged at the matrix level, the body comes to repair it, MMP-9 goes up
