Kinda hard to say if its the AI causing this or not compared to something else. I would get blood work personally before just changing up doses of every thing. How ever ( everyone can kiss my ass ) I feel like dog shit when I use a AI period flat I get tired, libido is slightly lower, BUT my joints hurt so dam bad felt like I was going to just pop apart. So it could be the AI BUT, there is no safer way to tell than to get blood work and for god sake be honest with the doctor.
Gear could be fake as well probably most likely possibly under dosed but would have to be greatly under dosed.
