The purpose of this clinical trial is to look at tyrosol's effects on endurance, strength, and fatigue resistance in humans. Additionally, the combination of tyrosol and creatine monohydrate will also be looked at to determine if there is a cooperative effect from using both together. It will be conducted over a 4-week period to compare the effects of the following substances: 1) tyrosol, 2) a placebo (a look-alike substance that contains no drug), 3) creatine, and 4) a combination containing both creatine and tyrosol. Endurance, strength, and fatigue resistance will be compared between groups through repeated testing (described below). Participants who pass initial screening will be invited on-site for day one (Visit 1) of testing where they will proceed with a series of tests which will include the following: (1) body composition; (2) cognitive testing; (3) full-body strength testing; (4) grip strength on both hands; (5) muscle power testing; (6 \& 7) Resting blood lactic acid testing followed by 5RM (repetition maximum) bench press, leading to multiple sets of bench press (based on the previous weight) completed to failure, followed by another blood lactic acid reading; (8) a repeat of the muscle power testing; (9) a 1 mile time trial run completed as fast as possible. After the 4-week supplementation period (\~28-34 days), all original measures will be repeated as before in the same order (Visit 2). Approximately 24 hours later (Visit 3) participants will then repeat all physical testing procedures except tests 1, 6, 7, and 8, to determine physical recovery. Additionally, questionnaires for soreness and perceived recovery will also be completed at the beginning of Visit 2 and 3, and again on its own as the only testing event at 48 hours post-Visit 2 (visit 4).
