Curious as to how clomid and mk677 only would go?

Clomid has been known to decrease HGH and increase the natural production of T. Both can and are used as a PCT but due to the increase of HGH counteract the clomid and clomid increase in T make for a good pair? Been doing more reaserch into both. What would the downsides be and the pros? Good idea or bad? Etc any thoughts are welcome
