I will be honest with you my friend

i have seen numerous guys at the gym start steroids with no solid base, if you start of being skinny during the course you may bloat and add water giving you the impression its solid gains but a few weeks after the cycle they all return to their normal skinny structure,

now you dont want to be doing this for the rest of your life bloating up and down, your body knows your thin and will do anything after your cycle to go back to its normal state being thin.

If you could reach around 200lbs naturally through hard training and dieting and then you decide if you want to cycle because if you do then at least you have a solid base to start with

If im honest i think you may be miscalculating with your calorie readings and getting to technical with the figures
