Yes. OTC stuff is generally overpriced and over-rated. Why bother with a stack of 15 different OTC products to lower blood glucose or raise test levels, when you can get real prescription drugs cheaper that are more effective....i'd rather do 3 weeks of clomid hell instead of stacking maca, avena whatever, tribulus, etc etc etc to get my drive back, and likewise glucophage is much better than any OTC med for lowering blood glucose.
