Product Features

Mass FX is a product that is intended to help boost testosterone levels, to thereby make it easier to build muscle and burn fat. This product is intended for bodybuilders, rather than a casual dieter, because it is not really meant to function as a traditional fat burner, but rather will help burn fat by the increase in muscle mass. This product claims to help you produce clean gains within the first three to five days of use. You will need to take four servings spread evenly throughout your day, which means a 112 capsule bottle will last about 30 days. Since this product increases testosterone levels, it is not safe for women to take. Too much testosterone can lead to increased sex drive, aggressiveness, body hair, and a drop in voice. You are advised to take a dose of this product in the morning, one 30 to 45 minutes before your workout, and one before bed. You should use this product for eight consecutive weeks, then stop taking it for at least four weeks before starting another cycle. Continuous use of this product is not healthy or safe.

Mass FX could be helpful for men who are constantly working out and lifting weights, because it can contribute to muscle mass. It will not be helpful for women, or for people who do not workout and lift weights on a regular basis. We only recommend it if you fit this definition and can take it as directed. This is not intended as a fat burner or an appetite suppressant and will not promote weight loss. If you want to lose weight, follow a nutritionally balanced diet, regular exercise routine, and consider adding a clinically proven safe and effective appetite suppressant or fat burner.

    I did one cycle of this supplement (4weeks) and I must say it did do what it said in regards to gaining lean muscle and decreasing stubborn fat. It was noticeable after the first week to be honest. I do have a good diet as well so additional to that I saw the gains immediately. I put on 6 pounds of lean muscle in 6 weeks. Downside: this product seemed to have given me acne in the most annoying places. My nose, my shoulders and in my head. It was annoying and I had to come off them immediately as it just got worse and worse by the day after week 3. My libido was through the roof also which isn’t a bad thing at all. I was literally constantly horny lol hope I’ve been of help
