There are a lot of factors that make it very hard to do a good study on these peptides. For one, such research is costly, and the wide availability of unproven peptides makes them less attractive to pursue from a financial standpoint, he says
Such peptides are banned in professional sports
Another review of studies involving BPC-157, as well as TB-500, GHK-Cu, and several other peptides, similarly found a lack of evidence to support clinical use of the substances
A longer life
I need to know what were giving patients rather than hoping that its good and being on the cutting edge. He and others are also concerned about the source of products
For instance, one known effect of BPC-157, KPV, GHK-Cu, and other peptides is angiogenesis
