Just got it yesterday, late in the day around 5ish,First thought.... should I try this this late..... YES!!! LETS DO IT.... So I opened the bottle and gave a sniff.... smells minty... AWESOME.... Took 1 with a lil OJ... and decided to hop on the eliptical for a 30 min spin after 15 min, at first I was a lil giggly... I think that was just the buildup though.THEN.... I was in THE ZONE.... Heart rate was 8-10 beats lower than normal, and breathing was not noticeable. I cruised through the 30 min in what seemed like no time....Focus was EVERYTHING!!! Thanks CL. I will have more impressions under different circumstances... to add to this log....So far... THUMBS UP !!!
