may not be AS effective, but the fact that the dosages are multiple capsules vs. just one, makes it more suitable for women. otherwise there can be alot of strung out ladies out there who may not have felt much with one cap of xenadrine but 2 was too much. at least with hydroxycut, the serving is 4 caps and you can cater it to your own body's tolerance.
so of course 1 cap of xenadrine may not be equivalent to 1 cap of hydroxycut.
