Optimum Gold Standard Gainer is a premium high calorie mass gainer protein powder designed for the trainer who wants to gain size fast, but not as fat. When it comes to building quality size, it’s not as simple as simply eating more. It involves a concerted effort with your training, your diet and your supplementation. Gold Standard Gainer’s unique formula is based on the best current science when it comes to building slabs of lean hard muscle mass.

Gold Standard Gainer is built on a foundation of complete dairy proteins, mostly from isolate sources. The carbohydrate blend includes oat, pea and potato and the fats include medium chain triglycerides, chia and flax. Obviously, this is not your typical gainer formula. ON took it a step further by making it easy to mix up in a shaker cup. No blender needed. This is the new Gold Standard for weight gain.

Sustained Release Protein Blend
When you’re trying to build muscle, you want to sustain amino acid delivery over longer periods of time. Fast digesting proteins are perfect for around workout times, but after a couple of hours, your muscles are starving for some extra protein. Slow release proteins are good, but fail to kick start that muscle building machinery quickly.

Gold Standard gainer contains a mix of medium too fast digesting proteins such as WPI, WPC, Milk Protein Isolate and Hydrolysed Whey to help you initiate muscle building and maintain it over longer periods of time.

Plenty of Carbs – Lower Insulin Spike
When it comes to bulking, carbs can be both your friend and your foe. They provide crucial calories and help to replenish energy levels, but they can also drive up fat storage and make you feel a bit sluggish. Enter Carb 10. 

Derived from peas, Carb 10 is a carbohydrate that is quick digesting, but doesn’t raise insulin levels as high as traditional carb sources. As such, you’re less at risk of gaining large amounts of fat and feeling lethargic and tired after you’re shakes.

Mass Gainer for All Levels
Whether you’re a seasoned pro or a newbie when it comes to bulking, the Optimum Nutrition Gold Standard Gainer has pretty much everything you need for a successful weight gain campaign. Easy to mix and not too heavy on the stomach, you’ll easily be able to fit 1 or 2 serves throughout the day. If you’re serious about gains, then you’ll want the Gold Standard Gainer in your arsenal.
