I received myin the mail on Friday and started on Saturday. I am taking 6 total per day, 3 pills, twice daily as the bottle states. I am taking 3 pills in the morning, and then 3 more about 30 minutes before my workout. I did a small chest workout on Saturday night. Did not notice anything, but I worked out at 7pm, when my normal workout is during the week around 3pm. Today will be my first "real" day working out with it. I have my upper body 5x5 workout to do today so I will report back with any noticeable changes.
Just for the record, here is a normal week of weights for me:
Monday: upper body 5x5
Tuesday: lower body 5x5
Thursday: upper body hypertrophy
Friday: lower body hypertrophy
