clomid is better than nothing. from eq-plex, you may be fine with running a pct combo like unleashed/post cycle. it will help any sides from occuring and if ur serious u can run hcgenerate to help keep what you gain.
first of all, clomid is not just better then nothing, it should be you primary pct product (or nolva). Even though your talking about non methyls, they still supress natural test just as much. Therefore, once you come off, you will likley face a estrogen rebound. Clomid is on the front lines of stopping this from occuring. IMO running any type of anabolic cycle without a SERM is foolish.
as for oct pct, they would be what I consider to be "better then nothing". they are good to start your test production back up as well, but really should be looked at after selecting a SERM.
As for cycle support, yes. it not only helps with liver, but with blocking dht conversion (saw palmetto- aka preventing hair loss), helps keep bp in check, as well as many other things. of course it is usually cheaper to just buy separate products, but if CS works better for u then use it. just remember to start it at least two weeks in advance.
