I haven’t seen muscle gain, or strength gains, or fat loss, but no question I feel a difference in sustained energy throughout the day! I take 5 pills with breakfast and 5 pills with lunch, and my energy seems to last all day! Im on my 2nd bottle out of 6 I bought originally, and Im hoping for a slight fat loss and muscle gain, but the jury is still out on that one! It is a bit of a chore to gulp down 10 pills a day, and takes some serious discipline to remember to take them, but Im committed! I haven’t seen a big drop in pain. I have chronic back and shoulder issues, but haven’t seen big gains there either, but Hopefully I will see incredible results!
