How important are a.i's when running a cycle. say test e at 500mg for 10 weeks. In some posts and the 9th edition of anabolics people say that A.I's are not all that preferred because they are pretty harmful. Rather nolva is recommended in case of severe estrogen related side effects. (Stating that the estrogen is good for creating gains to a certain extent) But then I read in other posts that estrogen should be controlled from the start due to a number of reason including the fact that E2 is a carcinogen.
I guess my questions are/ as follows
1) is it really necessary to run an a.i. or serm from the start?
2) Would nolva work just as well without being as harsh on the body if one is needed?
3) does test e even convert to E2? (i think it does but i'm not a biochemist or endrocrinologist so any literature on this would be appreciated)
