Going to look further into this, haven't come across it with other peptides either. I do struggle with a flattened mood on the dual-action medication, and nothing I've tried has genuinely countered it for me. Getting myself moving is the hard part, but once I'm actually doing something, I generally start feeling better about it. Lost interest in a lot of things that used to genuinely make me happy. Hoping now that I'm at goal weight and cutting back the dose, things will start improving.
