Caffeine Increases Testosterone

February, 4 2010

In yesterday’s Breaking News post, we talked about how winning increases testosterone production. That helps hard-driving competitors to be even more aggressive in their endless quest to continue winning. A different study, this one published in the International Journal of Sports Nutrition & Exercise Metabolism, found that consuming caffeine can also increase testosterone during training.

Researchers discovered that the more caffeine consumed, the higher the blood levels of testosterone produced. Sounds great – especially if you really like your energy drinks. But here’s a dose of reality: Caffeine also increases production of the catabolic hormone cortisol. The take come message here is to use just the right amount of caffeine to fuel training intensity and feed your gains anti-catabolic BCAAs after you’ve finished.
