what was your first cycle? and yes use both as recommended here. however if it was me, i would use only enough clomid as necessary. 100/50/50/50 should be plenty.
and x2 on the hcg. 250iu 2/wk would work well for that cycle. keeps your boyz in shape and assists in promoting a healthy recovery during pct. as Gixxer said, it's never a waste bro.
