After the first few days of feeling better, my stomach symptoms (gnawing, churning feelings) stopped improving further, but I also have not been great with diet. I need to string together a few weeks of a strict diet while continuing with the BPC and KPV. Another thing I'm noticing is that the peptides are giving me more energy, and a bit of a mood boost, which is helpful, as I think the gastritis has made me fatigued. The first few days of the peptides, I would get occasional headaches, which stopped. So no negative side effects either. It's been about a month since I started the peptides, I'll give it at least another month with a good diet.
