I have experimented around with a few of the herbs and I have to say that my favorite are the Cordyceps, Ant Extract, and Rehmannia. They have pretty much changed my life. The cordyceps work very well for energy and endurance especially on off days from the gym, or after a workout. The rehmannia has pretty much been a life changer for me. Levels of stress has gone way down along with anxiety. It’s giving way to happiness that I haven’t had before. I love taking the ant extract before I workout, because it gives me a different kind of energy that allows for stamina. Thank you Lost Empire for such great and potent herbs. Can’t wait to try some others.
