Review: Ran 2 bottles and unfortunately did not see the results I was hoping for. Noticed no increase with strength, endurance, aggressiveness or libido for me. I was really hoping for quicker recoveries and endurance. A couple of factors could have been: 1) started a very stressful job and 2) took on a new role at my job 5 weeks ago that increased my level of activeness. Don't think it's a bad product as it obviously works for some people, just not for me. At least I got 2 bottles of Peak Beta to go with it!
