Tribulus only works in very high doses for me, but it does work while I am taking it. Last cycle it was effective only at 6x750mg of a high potency brand. The previous cycle it was effective at 4x750 (so it is losing efficacy). I can’t recommend it though because I think it has the potential to lower one’s baseline. I am still experimenting with it.
I can’t advice you about psychiatric drugs. Taking those is the third worst thing anyone can do (you’ve already done the second, don’t do the first). I have extreme anhedonia and lack of motivation that are destroying my life and I wouldn’t take any, except perhaps a low dose Wellbutrin. I am still thinking about it. I know you are desperate though so you may have to do something.
