Love this

I didn't notice when I took only 1 cap. But taking 3 caps (2,250mg) of this does wonders for concentration for me. I totally feel it. I do take this with a range of other supplements and a healthy breakfast. This will for sure stay in my stack from now on.

Good energy levels!

Posted by Reviewer2944616 on Mar 23, 2014

I love this: it gave me good energy increase, so I could start exercising after a long slump. When you're in a rut, you need extra energy, motivation & support. This made my exercise easy and thus motivated me to keep going. The energy felt consistent without any jolts of too much at first and crashing after. I haven't taken it in a while, as I take breaks from supplements after 2-3 months (ideally should be taking 1 day break after each 3-4 days of intake, then take a long break after 2-3 months, so that your body doesn't habituate to it and so that the supplement still works well). That said, I got distracted onto other supplements for a while, but this one was a good one, so I want to start taking it again and see how I feel now that I work out quite a lot and on a regular basis. Will update this later.

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
