Honestly, I do not see why you would not want to take cordyceps everyday. Cordyceps gets better the longer you use it. Endurance athletes in particular will really notice a difference in supplementing with it everyday.
If you want a top of the line cordyceps product than look no further than MST's Cordygen. AN also carries DRIVE which uses cordyceps as well and is a great endurance formula as well that comes with some other nice benefits.
However, if your looking for just straight cordyceps...buy it in bulk. Nutraplanet used to carry it in bulk, but I am not sure if they do anymore. Regardless...I love the stuff because it works. Just my thoughts...
