I bought this product by watching its TV commercial. As I am a skinny guy from childhood, I thought to give it a try. I used it a month and now I am sharing my experience.
It is basically a Protein powder and contains steroids which is harmful for bones. It can also cause other side effects. However it also contains several vitamins and minerals which are good for health. Though I will suggest you to take protein and minerals in natural ways. There are natural ways to get proteins from food like grams, meat, fish, eggs, milk, etc.
Your body should capable to absorb high proteins then and then only you can take high proteins otherwise you will suffer stomach problem. You have to work out to make it consumable in your body.
It comes in many flavors, but it does’t count as they all are artificial.
Also you should not take it without showing to your doctor. This powder gives you extra calories which can go either way. It can make you sick and feel fatigue.
After using Endura Mass for a month, I gain little weight but also suffered several side effects like stomach ache, headache, etc. But some people said to have benefit from it. So, it depends on your body. But I will not suggest it to give it a try.
