Hey i havent really read what others have been posting but thought i would just throw a suggestion out there, i started a bulking cycle as i was very thin as well lets say 125lbs at 5"7 thin lol... Your going to need to stick to a good weight gain diet, combined with regular exercise and a very easy steroid stack. I might suggest Anardol (its easier on the wallet), and using test prop (yes that means a needle) shooting 1cc everyday. Dont worry its not that tough, research your biggest most accessable muscle groups and try hitting them. I like shoulder, and glutes. Use the smallest inject needle possible (usually 23 1") if your afraid of them. And two things to remember your not direct injecting into blood stream so it hurts far less, no need to find veins or that stuff. And secondly i have to say you cannot bulk and cut as effectively at the same time. Stick to a good bulking cycle and stay true to all the aspects (diet,workout,steroid stack), then when youve put on some desired thickness and healthy weight, consider your cutting cycle.
