Which one should you choose?

BPC-157 is better for physically repairing damaged tissue, while KPV is better for halting acute autoimmune and allergic inflammation. BPC-157 rebuilds the gut lining by promoting angiogenesis and cellular migration. KPV (a tripeptide fragment of alpha-MSH) is a potent anti-inflammatory that works inside the cell to downregulate NF-kB, the master switch for inflammation, and also possesses antimicrobial properties. Choose BPC-157 to heal a leaky gut, ulcer, or structural injury. Choose KPV to calm an active autoimmune flare-up, mast cell activation, or severe skin inflammation. They are highly synergistic when stacked for severe GI issues.
