I bought because of the good reviews me this product. But I was sadly disappointed. Remember no difference whether I now with or without the AAKG Train's. Strange: The intake recommendation in German: 1 capsule before training, take 1-2 capsules before the sexual activity. Instructions in all other languages: 2 capsules before exercise or sexual activity. In addition English is still that taking 30 minutes. should be taken before the start of training.
