I'd guess it's the Katanadrol v3 causing the problem. Apparently it's 6a-Chloro-androst-4-en-17b-ol-3-one, which is Hexadrone???
They have put caffeine into each serving to create with a diuretic effect and there's also some other herbs with a diuretic effect in the blend.
Def not what I would want to take with Mechabol!
Drop it immediately.
Edit"......... Katanadrol isn't Hexadrone, I think it may be 1-Andro, not sure, anyway, can't be bothered researching a product that uses caffeine with a prohormones, DS, etc.
