Guys, my info that might help some.
I can only tell straight forward how has been the effect of me, i can´t discuss stuff since I´m not knowledgable on the subject.
All the doctor gave me worked out, with the HCG, Clomid (HCG 75 ul every two weeks, Clomid 50 mg (10 per month) and Arimidex 1 mg, every day), the sex hiatus I had was just a matter of couple of days (when I wrote), I had great sex after those days.
After 3 months of the previous (HCG/Clomid), my Testosterone was still pretty good and high 907 ng/dl (241-827), my free test 20 (pretty high and good), my hematocrit just at the top limit 51 (40-51), my E2 still high even with Arimidex 1mg every day, 76 (when maximun should be 62, ´though it went down from 140).
I HAD NO SIDE EFFECTS OF ANY KIND.
So the doctor recommended now a Clomid only teraphy, to see how it´s my reaction to it, and since my Testosterone and Free Test is still great, also to see if the E2 comes down.
Guys, now with JUST with Clomid 10 days per month (plus taking Arimidex 1mg per day) I´m sex beast (more than ever), hahahaha. Feel good, etc...
Body wise: Taking testosterone was my hardest, but the post cycle with HCG/Clomid, and the one with Clomid I´m doing now is just ONLY a bit less hard, I was able to retain allmost all my gains, really difficult to notice any difference. Body weight is the same.
A GREAT NEWS: Using Crestor I was able to reach for the first time in my life correct numbers of Cholesterol, I¨m at 170 now (on the good side!), and the top limit is 200. Amazing, i tried different things for years in the past (been Fluvastatine last one) and never were under 220. Also, no high lipids!
I mentioned the Doctor some of the things suggested here, his answer was that the reaction of the bodys are always different, and that is just a bit of trial plus experience on his side (didn´t use any of these words, is just my VERSION of what he said, hahah), and he is "tayloring" the "teraphy" specifically for me.
Thank you all for your answers and I hope my experience helps others too. I will keep you updated through this journey, all I can say that my body just swimming, at 57, is like most 20-30 year old guys would like to have (by no means a bodybuilder look, but better than swimmers, ahahha). The "problem": all my age women, and much younger look very odd (old) next to me, hahah, like they could be my aunts.
