My personal experience...... been on trt for about 6 years now (damn, didn't realize it had been that long now). Anyways, been on Adderall for about 6 months or so now in conjuction with my trt and occasional "on cycle" of test/ tren mix. No major issues, mine was prescribed and it really doesn't affect my appetite for some reason. The only thing I noticed, is it seemed to effect my sex drive somewhat (negatively). So I looked into some, appears that Adderall has a tendency in a lot of males to somewhat reduce your testosterone levels. Assumed since I was on gear it wouldn't affect mine. So just to test that theory, I stopped taking the Adderall and my sex drive immediately came back up. Bad thing is the Adderall do help the ADD issues I have (nothing major, nonetheless it helped). So I got back on it and then increased my test dose slightly to see if that would counteract it. So far it seems to, but always remember, everyone is different. What's I think worked for me, may not work the same for someone else. I never proved my theory with a blood test. That's next on the list. I'll let you know when I do.
