Yes. The reason we keep telling new people to rear, read, read, is because anabolic use is so much more than just following a "recipe" of what to take and when.

.25mg EOD is better but you should be ok with .50mg EOD. The risk is that at the higher dose you may crash your E2 (and you should understand what that means and why it's a problem).
Can't help you with HCG. Finding a source is part of your process but I will say most HCG nutraceuticals sold in nutrition stores are garbage and NOT what you want.
