I have tried creatine in the past and did not like the bloating and weight gain. I am 59/female, and constantly battle that spare tire in the middle that always tries to appear at this age. I recently decided to lift heavier, and this product has helped me be able to increase my strength, without increasing my waistline! I have actually lost 3lbs in the past few weeks. I also walk on a treadmill and use the L carnitine from this brand. Good stuff!
