it is naturally occurring, nontoxic, and is active at a very low nanomolar concentration.11 Another piece of research described GHK-Cu as a safe, inexpensive, extensively studied compound.3 These conclusions primarily apply to topical GHK-Cu, but even with injectables, the lack of serious adverse events in animal subjects points to a general tolerability regardless of the route of administration
Indicatively, BPC 157 induced a NO-release of its own [49,67,68] and therefore counteracted both NO-synthase (NOS) inhibition (i.e., N(G) nitro-L-arginine methylester (L-NAME) hypertension and pro-thrombotic effects) and NO overstimulation (L-arginine hypotension and anti-thrombotic, pro-bleeding effects) [49,67,69]
