Began by taking your product one scoop mixed with juice before a meal. Initially I experienced some stomach upset. I thought there might be an adjustment period so I continued taking your product once daily before a meal. I still experienced stomach issues. I stopped taking the powder for a week, the intestinal discomfort went away. I thought it might just be that my body didn't react well to your product so I asked three of my friends if they would be interested in trying your product. They agreed, and I didn't inform them of my discomfort. They each used one scoop with water or juice before a meal on a daily basis for one week. Two of the three reported that it was like taking a laxative, the third said after taking the product for a week that he saw no difference in how he felt. I know a week is probably not long enough to achieve any benefit. So there are three of us that experienced stomach upset after using your product for a week. I'm sixty seven, do free weight and body weight training three days a week, and usually get in ten thousand steps a day. In spite of this regimen, my muscle mass is gradually declining. That is what led me to try your product. I realize you can't stop Father time, but i was hoping your product would help slow the process. I'm going to give your product one more shot in hoping my body will tolerate it so it can help achieve the desired results.
