I first heard about them from Buffie the Body. She had a contest on her youtube channel in which the winner would recieve a free bottle of this product to help them gain weight. The pills help you to eat more and it slows your motabolism .
In my opinion the pills worked because many many people told me that I have gained weight or gotten thick lol.
But what you do is take two pills atleast 30 minutes before your meal and take them three times a day. Also you must (in my and several other people's opinion) do some strength training to further assist you in your weight gain. Eat a healthy meal too but make sure it's calorie dense foods.
I recommend this product to anyone who is trying to gain weight. You can purchase them on the company's website or just google the product. It should take two bottles to reach your goal.
