BPC-157 200-400mcg daily potentially indefinite with periodic breaks

Therefore the ability to bind GSH is not related in anyway to a requirement (or a lack of requirement) of GSH for growth

Accordingly, a ZSWIM8 variant harbouring charge-reversal substitutions in RBE1 had reduced ability to rescue TDMD in ZSWIM8-deficient cells and reduced polyubiquitylation activity in vitro (Fig

This creates a pharmacokinetic advantage: higher hippocampal exposure with lower systemic exposure reduces the risk of peripheral side effects while maintaining therapeutic receptor activation
