I gifted you a platinum membership for 7 days. Take advantage of it, use the search feature. You won't get all the answers to your questions in one or two posts. I see you already started a second post asking how many cycles it would take to get an increase in arm size.
There is a lot to learn and its better to search for the answers yourself. Come back and post after doing a couple days of reading, give us your height, weight, age, training experience, diet, etc. You'd be surprised how much you can gain just by eating a ton of the right foods and training hard.
We're here to help, but to be honest, your questions seem a bit amateurish and lack any research. If your serious about taking any anabolics, and it should be thought about seriously, do the research yourself so you know what to expect. Don't expect everything to be handed to you. Come in armed with some knowledge and ask some good questions.
