If you turn back the bodybuilding clock, you’ll no doubt remember that old stand by, the “weight gainer.” You probably picked up an economy-sized bottle when you were playing high school football–before you became a competitive bodybuilder. Along with the Animal Pak, a quality weight gainer was probably one of the first supplements you ever used. For years, supplement companies sold tons of this stuff. Why? Because it worked. Today, the weight gainer has lost much of its popularity. And over the years, the weight gainer has changed very little. But whether you grew up bodybuilding in the 1980s, 1990s or today, one thing remains certain: to bulk up and put on quality muscle weight, you need plenty of calories. And when you can’t eat any more, you need more calories. Gain Fast 3100 helps. Big time. For most of us, putting on weight is a simple process (for some, all too easy). Eat more of everything–quality protein, whole foods, vegetables, eggs, milk, fruits, good fats, and the like. For others, gaining weight is a difficult proposition. You have a hard time eating every three hours. You always feel full. Maybe you’re a “hard gainer” who can’t seem to put on weight no matter how you try or how much you eat. Gain Fast 3100 has been designed to fuel your body with up to 3100 quality calories per day. But sometimes, even mega-calories aren’t enough. Sometimes you need something more, something like anabolic boosters, performance herbs, natural plant sterols, EFAs, digestive enzymes, and muscle optimizers. We’re talking about ingredients like L-arginine, MCTs, IGF colostrum, L-carnosine, vanadyl sulfate, plant sterols (e.g., beta-sitosterol, stigmasterol, fucosterol, campesterol), inosine, ginseng, pyridoxine alpha-ketoglutarate (PAK), choline, inositol monophosphate, and other good stuff. Where else can you get this kind of formula? Nowhere else in the world. It’s only available in Gain Fast 3100. With Gain Fast 3100’s exclusive “Get Big Quick” Formula, you get over 3100 calories from 150g of protein, 596g of carbohydrates, and only 15g of fat.
