I like 6 weeks myself. Clomid 100/100/50/50/25/25, Nolva 40/40/20/20/10/10. May be a lil overkill for a short run but great for 16-20 weekers. Does that help?
These doses are ridiculous (the first 2 weeks)
Clomid, at 150mg+ daily has been shown to consistently inhibit GnRH release, meaning at higher doses it's counter-productive.
50mg clomid and 20mg nolva is all you should ever need. For an 8 week run, I'd probably run clomid 50/50/50/25/25 and nolva 20/20/20/10/10
There's a handful of other combinations as far as dosing goes, but keep it in the general ballpark at least. 100mg clomid and 40mg nolva together daily is not something you should ever need, keep in mind the HPTA is a fairly sensitive system, after all it regulates hormone balance, so flooding it with chemicals unnecessarily I feel like would only desensitize it in the long run... of course it recovers, but there's never a need to take that much SERM together
