Hello, I Am 22 And I Weigh Only 45 Kg.

Hello, i am 22 and i weigh only 45 kg. I had joined gym 2 years agO.but havnt seen any change in my body. I tried many supplements and now i am thinking of using steroids. I know the harmful side effects of these steroids, but i thought of taking it because i think that i have a low testosterone problem also. My sex drive is too low.its kind of embarassing...i have heard of trenbolone acetate and testosterone injections..i was thinking of taking it at very low dosage..even less than the normal level. Because frankly speaking i am too scared of using these. but u see, i have to gain weight., i eat a lot,exercise..would taking 10mg/week of trenbolone acetate be good enough as considering both the positive and balancing the side effects.
thank you.
