Excellent. Use 3 after workouts and take 2 later in the day and feel recevory to be better, quicker and feel my "Clean" reps going up consistently. At 55 and being a former powerlifter, i know the necessity of recovery and your product will always be a constant in my arsenal. Looking forward to using more of your other products as well. 5 star endorsement from me. Be strong, be well and be in good health to all.
