So I used to take adderall in very small doses (10-15mg), once or twice every couple weeks, to study for exams and what not. It was incredibly effective everytime I loved it. During the time I started taking it I was unknowingly low in Testosterone and it really helped me with energy and focus throughout the day.
Searching for anything that could potentially help how non-existent my libido was at the time, I started messing around with DHEA supplementation. Usually about 50mg a day sometimes I would even take 100mg. I stopped after a few weeks and had really bad withdrawal from it for a couple weeks after.
Ever since, adderall is completely ineffective. In fact, the first time it didn’t work I actually thought I forgot to take it and I didn’t. Felt absolutely nothing. Same story with pre-workouts such as C4. I didn’t become immune to the dosage of adderall because I took it so infrequently. My neurologist and neuroendocrinologist both had no answers for this.
This started in January and I still do not feel anything from amphetamines or pre-workout supplements, so bizarre. I have since started treatment for my low T and my T levels are through the roof (although my estradiol is high too). I thought this would be a good place to gain some insight on this problem as it is really annoying.
