Well, it would be best to run the Winny right up to the end. Thats the most common way to do it, but you can run it like you want.

"you shouldn’t do hcg until three weeks after your first shot, because sust has a half life of 21 days. Not sure, let me know." Did you mean to say "after" your last shot? You can run HCG anytime. And 1500iu for each shot should do the trick. If you don't notice testicular atrophy dissipating, then you know you will need higher doses. Yeah, you want to take some Nolva with the HCG. Your estrogen levels will get real high with the HCG.
