since i love the taste and nutritional value of cordyceps as a whole food i figured it would be interesting to try an extract so i got doctr's best freebie,it was a big surprise for me to find out that as an extract it has a remarkable effect on my energy levels and drives me not to be a potato couch in a natural way as if i decided it,but the 2 cordyceps caps it take decided for me and thats a very good effect so i decided to buy their 60 caps bottle and i'm very happy with it.it has a far better effect on me than other adaptogen such as holy basil or even korean ginesng and it lasts for a few hours ,i can't compare to other extracts for now as its my first trial but i will update when i try several different types of cordyceps extracts like cs-4 , Cordyceps Cephalosporium Mycelia , Cordyceps militaris , Cordyceps Sinensis Aweto , cordyceps sinensis mycelium and maybe the wild harvested cordyceps.the only downside for this product is the unnecesary fillers in the capsule but other than that i am more than happy with it,even amazed and its hard to amaze me!....you are welcome to rate & read my other reviews

Support immunity and kidney function

Pure herb (not extract) in capsules. Great for a wide scale of problems. It has also mild blood-thinning properties.

Favourite supplement.

Posted by Reviewer3099688 on Feb 28, 2010

Been using this for a few years now, one of the very few supplements that actually does what it claims. Very effective to increase stamina in men and women. I highly recommend this.

Athletic endurance booster

Posted by Reviewer2347683 on Mar 06, 2011

I've been taking this daily along with Now Foods Rhodiola for a couple of years to increase my endurance road cycling. The effect of the combination is amazing, and quite noticeable when I don't take it. I find this to be an excellent quality product at a very reasonable price.
