After all this time, the only thing I would change is the arimidex... I now prefer aromasin/exemestane because it's much more stable in my system. Arimidex is still a good choice for a first cycle to see how you react to it. Some guys I know swear by arimidex and love it, others have moved on to aromasin.
I can't stress enough how important the hcg protocol is... I've done it both with and without and the difference was STAGGERING!! I would say I saved 2+months of recovery time by utilizing hcg, not a bad deal for spending less than $100 extra.
And as some have said, start with 25mg ED dbol if you go that route, not 50. 50 can give bad back and calf pumps if you aren't used to it!
