Question 1) Yes you will want to do them again.In terms of health NO.2)First cycle no it will take time to build muscle and keep it.3)YES,I am only speaking about you because you are not at your natural limit trust me .If you want to find out just do it,very hard to tell you what you will keep after 1 cycle.I will say you will be bigger than before unless you do something really wrong.This is not rocket science
I am afraid I don;t quite get you.
First of all, why would I need other cycles if I would reach my goals with the first one (and may be another one)?
And secondly, you seem to contradict yourself - you say "I will say you will be bigger than before unless you do something really wrong." and yet "First cycle no it will take time to build muscle and keep it", then if I am not getting anything of the first cycle - then there is no point in doing it... is there?
