The only time I've had this was with Tirzepatide, and even at a low dose of 1.5. It started showing up at 2.5, so I lowered it due to that plus stomach problems. Anhedonia sucks, I've dealt with it previously. I think low dopamine is behind it. Maybe try Semax to offset it – that worked for me alongside the Tirz.
I just began using the BPC and TB500 mix because of an injury, and now I'm dealing with anhedonia – no emotions, feeling apathetic for several days. This same issue hit me a while back with retatrutide, so I figured it was only that one. But checking Reddit shows others have had it with the Wolverine stack too. Maybe I'm just susceptible to it. Anyone else run into this?
