Hey guys, my dad has been complaining about bad joint and knee pains when he runs (he usually runs about 3 miles 4 times a week) so I gave him my tub of bulk cissus from nutraplanet. I understand this is not usplabs cissus, but does it still work pretty effectively? He has only been taking it for a day, but I have him taking 1g-2g twice daily....does this seem right? Should he be taking more/less? I have never taken the stuff, so I don't know much about it, but I see many people raving about it so I told him to give it a shot. How long does it usually take to see good results and reduce the pains?
