Yes, I can see what you mean about 8 week cycles. I know my test kicks in so fast (much faster than most people) because normally by week 2 im up and kicking and have gained 5-10 pounds. for me that is how I know it has kicked in...the sudden weight gain from one day to the next.
I could see the 8 week cycle working for me, but I mean OP you probably have 2 bottles of Test E...so why let a couple C's go to waste?
I read some more about letro, and still disagree with you but that is your perogative. Maybe you should CONSIDER running aromasin/adex while on anadrol strictly because Letro is so rough on estrogen and the gains from anadrol are estrogen-related.
I have run anadrol with no AI in a cycle with deca and test, had no gyno issues and my estrogen was not bad whatsoever. but it does effect everyone differently.
Usually around week 2 or 3 with test C or E i can really start to feel it work. I can tell by looking at my traps. At a certain point I'll wake up and they will look different. Thick and swollen.
