i just finished a bottle of cissus drol, i found best results were around 5 caps a day ( 2 more than they suggest is all ). i didnt get like a "feel" from taking it like i would from a PH but it was decent. i used it in a bulk and ended up puttin on 20 lbs but most of it was from eating eating and lifting. 3 out of 5 stars, as far as if its ok i would think so, nothin in the ingrediants that makes me think otherwise but im not positive so yea prolly ask the doc then...
