I don't usually bother to reveiw products, but this one in outstanding. Doctor's Best, Ultra Cordyceps rates up there with the best cordyceps available. There's another brand that is also excellent, but it runs $20 a bottle -- Doctor's best is equal to that other brand at less than half the price. You can expect a good deal more energy, and much better oxygen utilization. It tends to slow your heart rate. Sherpas use this to help them climb Everest without oxygen. I use it to improve my cardio workouts.

If you can afford it, try dosing this at 4.5 grams per day or 6 caps. Yes, it's expensive, but at that level you've reached the full benefits....which are... great energy, super anti-stress, and recovery from past fatigue and stress. Try it 5 days per week to keep it more affordable rather then daily underdose.
