I got my free samples from AI last week in the mail. First I'd like to thank the company for making great products and giving out free samples. Thein both flavors were great. I had good pumps and energy throughout my workout. I started drinking it about a half hour before the workout and it help me through. The pro is a great product and the lemonade taste is awesome. I took the hgh pro last night and slept great. I do pre calorie cardio in the morning and lift in the evenings. I do a lot of olympic style and have a problem getting to sleep. This seemed to help, but with only one night, it's hard to tell. Overall, I'm very impressed with these products.
