I've been using this for just over two months now, and the difference is incredible. At 61, I had resigned myself to steadily losing strength and energy every year. Within the first month of taking Old School Labs Creatine For Women, I noticed I could walk up the stairs in my house without getting winded. Now I'm back to taking long hikes on weekends and even started light weightlifting again! My arms and legs have actual muscle definition for the first time in years, and I've lost 7 pounds of what I now realize was mostly lost muscle, not fat. The best part is I don't crash at 2PM anymore - I have steady energy throughout the day. I was worried about bloating based on what I'd heard about creatine, but I've had absolutely none. This has literally changed my daily life and how I feel about aging. Worth every penny!
