The Dr Max Powers testoterone booster is great - ofcourse it improves sex drive [like large amounts of testosterone would if you take a larger amount], since it is the real deal. I would definately recommend this product to men whose levels of testosterone were diminishing, as with age. I Ordered the Dr. Max Test Boost product as supplement to boost my energy levels and such. I took one pill each morning with a meal.
