BSN True-Mass is a high-calorie, high-protein supplement that is intended to assist athletes in gaining weight. Because intense exercise burns many calories, athletes often have trouble gaining weight. In sports such as bodybuilding and football, gaining lean muscle mass is required for optimal performance, so a high-protein weight gainer may be helpful. The specific ingredients in BSN True-Mass may make it more effective than standard protein powders at improving body composition, but results depend upon your diet and exercise programs. You should consult a doctor before using BSN True-Mass or any other supplements.

The stated intent of BSN True-Mass is to encourage weight gain. You may accomplish this goal when using BSN True-Mass, because it is calorie dense -- BSN's official website notes that 630 calories are in each serving of True-Mass. You can also add more calories to True-Mass by mixing the supplement with milk or juice rather than water. To gain weight, you must eat more calories than your maintenance level requires. Because the average daily intake of calories is 2000, one serving of True-Mass comprises more than 30 percent of your daily caloric intake, and it will help you reach a caloric surplus. Professor Richard D. Mattes of Purdue University notes that liquid meals are less filling than solid meals, so True-Mass may help you consume more calories.
Improved Energy Levels
Although BSN True-Mass is not marketed as an energy drink and does not contain stimulants such as caffeine or yohimbine, the supplement may promote an increase of your energy levels. Although stimulants do provide energy, your body is fueled by calories, and carbohydrates are your body's primary source of energy. One serving of True-Mass contains 76 grams of carbohydrates, which is a fourth of the daily recommended intake. In addition, True-Mass contains 100 percent of the daily recommended intake of vitamins B-6 and B-12. MedlinePlus notes that B vitamins help your body convert food into energy, which may help improve energy levels.
Lean Muscle Gain
Although lean muscle gain requires resistance exercise, consumption of BSN True-Mass along with a well-designed workout plan may promote lean muscle gain. To gain muscle, you need to be in a caloric surplus, which the calorie density of True-Mass may help you achieve. In addition, BSN True-Mass provides 46 grams of protein per serving, which is 92 percent of the daily recommended value, according to BSN. One of the protein sources, whey protein isolate, in BSN True-Mass may be particularly valuable in promoting muscle gain. A study published in the October 2006 issue of the "International Journal of Sport Nutrition and Exercise Metabolism" found that supplementation of whey protein in conjunction with exercise encouraged more lean muscle gain than other protein sources.
