Brief summary: This study is assessing the effects of a pre-workout dietary supplement.

Detailed description: The purpose of this study is to examine the acute effects of a pre-workout dietary supplement at a standard dose and one that is delivered at 150% of the standard dose on energy metabolism, cardiovascular hemodynamics, blood metabolites and mental focus.

Eligibility criteria: Inclusion Criteria:

* Participants must be apparently healthy males and/or females between the ages of 18 and 40
* Participants must have at least 6 months immediate prior history of resistance training including the bench press and leg press/squat

* Participants who are intolerant to caffeine and/or other natural stimulants
* Participants who are pregnant or lactating women
* Participants who have a history of smoking
* Participants who drink excessively (12 drinks per week)
