I don't see any reason to supplement HCG with clomid. I think those who do are in a post cycle transition. Clomid stays active for 5 to 7 days much like HCG - just a different pathway to your balls.
Only recently I heard about using clomid E3D. If indeed that protocol is effective, wouldn't it be a viable alternative to HCG? I imagine infrequent dosing would eliminate the toxicity issue. I posted this question on another thread but no one has responded. Quite frankly, I'd rather stimulate LH production that replace it.
