Opened bac water usually follows a 28-day window unless the label states another period, and that opened-vial window never extends beyond the original expiry
GIP (Gastric Inhibitory Polypeptide) Receptor Agonist: This receptor also plays a role in insulin secretion and glucose metabolism
In one study, DSIP was suggested to inhibit somatostatin, a protein produced in muscle cells that inhibits muscle growth
