The delivery was fast. For product itself: The effect on strength and energy during exercise is quite amazing. After about 2 to 3 weeks taking one really noticed a significant increase in strength and endurance. I was amazed also that it has come true, that one is aroused sexually faster. But this is unfortunately very positive geschmählert by the side effects. 3x2 tablets is too much anyway. I took 2x2 plus a spread over the day. Unfortunately, I quickly got them violent flatulence. So I always took only every 3 St. 1 tablet. But that did not help. Flatulence remained until today. Very unpleasant. Would therefore no longer buy this product.
