I bought my first bottle of MAX SIZE and took 2 tablets at once. It was about 45 minutes, my heart was started to race. My heart beat went up to 190 times per minute. I mental concentration was unforced and got bad anxiety. I had to lying still to keep my heart rest. If I make a little movement, my was started to raise up again. I talked to myself that I was so lucky not to have a heart attack. My chance of having a heart attack was very near. I suggest that people should not take the supplement to increase their penis size. It won’t worth to try. If you really want to try it, I advise you to take half of tablets and gradually increase as your body tolerate to it. Thank you for reading.
