What Is Pentadeca-Arginate (PDA)
You will need to draw up bacteriostatic water and reconstitute the peptide prior to injecting
While animal studies suggest safety, long-term human studies are lacking
Introduction We focused on the stable gastric pentadecapeptide BPC 157 ( Thus, we suggest that one single application of the NO-synthase (NOS) blocker N(G)-nitro-L-arginine methyl ester (L-NAME) may induce retinal ischemia in rats, and that the stable pentadecapeptide BPC 157 may be the therapy, since it may interact with the NO-system and may counteract various adverse effects of L-NAME application (see In the previous eye research studies, BPC 157 counteracts atropine-mydriasis, but it also opposes an immediate and hour-lasting miotic effect of L-NAME in rats and guinea pigs, and participates in pupil control potentially via NO-mediated and cholinergic mechanisms ( This may be essential for the effective counteraction of the damaging effect of the retrobulbar L-NAME application
