sorry I didn't respond sooner, I am just starting week 3 of xf and havoc, currently at 40mg/ED (am, noon, 2 prew in evening), and 1250mg of xf (am, pm, 2prew, bedtime).
This is my first cycle, didnt know what to expect. During the day I feel hard and slightly pumped, vascularity is up. I am leaning out very nicely and muscle mass is going up, I have gained a solid pound in each of the last two weeks and getting cuts in places I didn't even know existed. My recovery is very good, considering I started DC last week and doing 4 workouts a week instead of three. RPM adds a nice preworkout boost, as I don't really FEEL xf and havoc at workout time beyond what Xceed and RPM provides (but the results I definitely feel, I think I know what back pumps finally means).
I opted for the stacking as there seemed to a real synergy on paper in respect to AR stimulation. I havent hit the xf DOMS, but since I am doing DC not sure if I will or if I will know its from xf or DC. I am going to run both for 4 more weeks, upping havoc to 50mg the last couple of weeks so that I finish the bottles.
part I hate about my first cycle is I keep rethinking my PeeCeeTee, trying to avoid the kitchen sink mentality, but dont want to underestimate effects of havoc. So far libido is great and the boys feel the same.
