With all due respect to all here, I have to disagree with what has been said regarding the hcg. Hcg is used for boosting sperm counts to ensure the propagation of farm animals. It has no healthy or constructive use at all in steroid cycling.
Although in the short run it will make the user feel like he has recaptured his natural test production, in the long run it will only further supress the hpta, no matter how little the amount is that you use.
Stick with just plain old arimidex or femara throughout your cycle. Calculate the length of time it will take the esterfied steroids to clear you system, - that is the point were you quite taking the AI and begin the SERMS if you must.
As for when your cycle will kick in, that usually happens between the third and fourth week.
there are too many people on this board who have inadequate experience with steroids, and are just rehashing someone else's second-hand information whether it may be wrong information or right information, they have no clue.
