I have an interesting stack in mind. I've just started using Activate Xtreme, along with RPM during my workouts. I'm waiting for my Nutraplanet order to come in, which contains another bottle of Activate Xtreme and a couple of bottles of Drive. I'll be running the 3 products together for a few months time, with Drive/Activate Xtreme daily and RPM during workouts.
What I can't decide is how many caps of Drive to be taking daily. I found from the sample packs I tried out that 1 cap of RPM and 1 cap of Drive was very strong (I only weigh about 150 pounds). I'll be dosing Activate Xtreme at the recommended 4 caps per day. As all 3 products I'm stacking contain iicariin, I'm wary of dosing RPM and Drive much beyond the label recommendations to start out. Are there adverse effects from excessive iicarin consumption?
