is hcg really so important in a test only cycle?

[foidannhialator]

I'm about to do my first cycle of test E 300mg every week
was wondering what you guys think about the importance of hcg to prevent infertility?
I know that some people say it can only be used for pct and honestly I'd rather do that because it is very expensive but I've also seen some people take it throughout a cycle
need opinions

depends on how long your doing the cycle 2 months youll prob be fine but for more than 3 months you should stack hcg
