Packaging and Stability Because GHK-Cu is oxidation-sensitive, use opaque or airless containers
Even if the solution looks clear after thawing, the molecular damage is invisible and permanent
BPC-157 sits explicitly on the WADA 2026 Prohibited List under section S0 (Non-Approved Substances), prohibited at all times in and out of competition for athletes under WADA jurisdiction

It was originally isolated in 1977 from the cerebral venous blood of rabbits and has since been found to be present in small amounts in human brains and plasma, with higher concentrations later in the day.3 4 It, or a similar substance, is also present at higher concentrations in human breast milk.5 Because DSIP can cross the blood-brain barrier and is easily absorbed via the gut (unusual for a peptide), some researchers have hypothesized that it may facilitate post-feeding sleep tendencies among newborns, though it remains unclear whether DSIP truly has a hand in neonate sleep-wake cycles.4 5 6 Its mechanism of action is likewise unclear, but it may have something to do with endocrine regulation
Store GHK-Cu as a lyophilized powder in a tightly sealed vial, protected from light and moisture
