I've been on the cissus/Powerfull stack for 13 days so far. I have been extremely tired/lethargic and everyday I wake up feeling sore and stiff. The pain in my shoulder has NOT gone away at all, and may have gotten even worse due to the stiffness in the morning. The only thing this stack has done so far is give me crazy dreams. However waking up everyday feeling more tired is not worth it. it also somewhat increased my libido, but noticable anabolic effects = none. if anyone else took this stack and had a more positive experience let me know. My vote is this stuff is worthless.
