I drank it for about a month and a half during the college entrance examination. It seems like a small bottle of 7.8 yuan (I didn't know the current price when I took the college entrance examination in 2008). As for the effect, there were people who drank Life No.1, Bone Sweat Essence, 2 1 Jinweita, Kingsley. When I first started drinking more than half a month ago, the effect was particularly obvious. When I took a nap in the morning of senior three, I really woke up immediately. After drinking a bottle of wine and sleeping only six hours a day, I am full of energy! However, due to drinking too much in the later period, the effect seems to be not so fast, but the effect is still there. As for the side effects, I feel fine, there is no discomfort, and there are many people drinking. After all, it is an old brand produced by regular enterprises! In short, you will know whether it is good or not after using it. At least I feel ok. Me, too. 12 There's not much time for the postgraduate entrance examination. Come on!
