you should not be using steroids whatsoever at your weight... you could easily be 25 lbs heavier naturally... using steroids at your weight in comparison to your height is a terrible idea man... thats fine you think you look good and you very well might but that doesnt translate to steroid use because you feel you look good.. the numbers do not lie... using steroids being that far undersized on where your weight should be can be extremely detrimental to joints, bones, ligaments and tendons and will ultimately lead to non stop injuries... very very bad idea
