In addition, I would like to remind you that drugs that lose quickly are easy to rebound. It is generally not a big problem to control your diet slightly within one month after taking the medicine.
As for the internal exercise pills, I advise you not to take them. I have eaten it, and the side effects are very big, which makes people feel uncomfortable. After eating 10 days or so, I have the symptoms of anorexia. Even if I eat a little, I will vomit, which is very painful. I was so scared that I stopped taking the medicine immediately. A netizen spent more than 20 thousand to treat anorexia because he took diet pills, which was not worth the loss.
My Lord, I have already said it in detail. The merchant who bought it before has long forgotten it. Who will? You can check the anti-counterfeiting code for the ob you bought, and the merchant will pay for it if it is fake. Anyway, it's only tens of dollars. (Your 30 is really hard to get)
