Can you take Alpha Male by itself without anything else and be OK, anti-estrogen wise? I know that Alpha Male has Vitex and that is one of the 4 ingredients in M to keep estrogen under control, but do you really need to take M being that Vitex is already in Alpha Male? I am more concerned with the anti-estrogen ingredient. Also my local vitamin shoppe used to be able to get M from Biotest directly but now they say that M is discontinued, is this true? Can it still be ordered from T-Nation or is there something else that you can recommend?
