Wow, if there ever was a topic of debate, this is it. LH, do a search (on this site and on the web in general) on terms like HCG, clomid, nolvadex, arimidex, letrozole, anti-aromatase, Luteinizing hormone, LH, HPTA, hypothalamus, gonadotrophin, and post-cycle recovery (just to name a few).
This ought to get you up to speed. Sounds like you must have as pretty hardy system to have done so well so long, but the past few mo. must have really sucked. Other factor for you of course is age...
Basic idea is to restore the normal hormonal cascade among the hypothalamus, pituitary and gonads, while minimizing the effect of cortisol. Some of this can be done by keeping the players (at leasat the gonads) in shape when on (with HCG), but most focus is usally on clearing the inhibitory chemicals (the gear) out of the system and minimizing the effects of the residual hormones (especially estrogen, when it comes to restoring testosterone) ASAP after the cycle (not several mo. later...)
Would help if you told us what you were taking. Also, will this year be like last?... If so, then there is no use in doing "recovery" (if you could call it that) would be useless, b/c you will / would be back on in a few weeks.
