At the low pH required to keep ascorbic acid stable (typically pH 2.5 to 3.5), it donates electrons to Cu2+, reducing it to Cu1+
However, they can affect blood sugar, increase hunger in some users, and carry slightly more side effect risk
Unlike many peptides that degrade rapidly in the digestive system, BPC-157 demonstrates remarkable stability in gastric acid, which has contributed to interest in both injectable and oral administration routes

The practical solution: use a smaller reconstitution volume (1.0 mL) during the early titration phase so the total solution volume is smaller and you draw more per dose (relatively), or accept that you will waste some peptide during the titration stages
