Bought the structure at a discount, the price is very pleased, and the combination of beneficial ingredients - even more. Diluted with water and drink directly on during a training session, I saw the rise of strength and energy, the mood at the height, and I was no longer sleepy fly ... Definitely worth the money, and for me the naturalness of this vitamin - the most important thing. Ordered one more to the bank! After a month noticed that hair has become stronger and no longer fall out! On an empty stomach is better not to drink, I feel bad, and notice of 30 ml is not a complete cap !!!
