What exactly leads to the anhedonia induced by amphetamine abuse?

After an adderall addiction, I find myself trying to fight the resulting anhedonia. I've been through 2 vials of BPC 157 in my 2 months clean and it helped lots with every other problem amphetamines caused except for the anhedonia (may have helped a little with the anhedonia, but I still have a long way to go).

I'm not a neuro expert, but I'm trying my best to figure this out, so bare with me. Sort of desperate

Would you recommend something that upregulates dopamine? Or an NDMA receptor antagonist? Both?

Keep dosing the BPC?
