On the newest bottles it says to assess your tablets one at a time to find out how many are best for you. With that being said, I am 5,8 230 or so...and 3 work just fine for me. You will be best to start with 1 and after a few days bump up and see where you're at. Exact serving dose is 3.
I hope this helped
Cordyceps (especially the strain that we bring to our customers), help increase oxygen uptake by up to 40%. Kind of like how herbal inhalers help people with asthma that prefer a more natural way of healing their natural issues. Instead of using something that is man-made and potentially very dangerous, they opt for something from the earth. A plant...or hmm...perhaps a fungus?
Thank you for your concern, but until you try these products, you will not know how well they work, and the biggest loss in that scenerio comes to you, your lungs, and your training.
