I'm doing the exact thing right now, as a matter of fact. I am hoping to shed body fat, maintain muscle, and add quality to the muscle I have.
No noticable side effects. This is my third week taking HOT-ROX I just started the Carbolin 19 on Friday. No jitters, no dizzeness, no dramatic BP increase. As far as results, I'll let you know in a few weeks if you hit me up.
It should be noted, I have a pretty high drug tolerance in general, and caffiene does not affect me strongly (however lack of caffiene does!).
My dosing is usually as follows- HOT-ROX upon waking (5am), afternoon (@2pm), Carbolin 19 with breakfast (730am) and lunch (1230pm).
I'm also taking a Tribulus/ZMA product, and take Power Drive pre workout when I feel the need.
