Mass Gain is CALORIES, pure and simple. It’s specifically designed with a 4:1 carb:protein ratio for the hard-gainer who needs quality calories to fuel their muscles. Not just calorie quantity, but calorie quality. 52g of high quality, gently processed, low temperature filtered whey protein ensures your muscles have plenty of amino acids to recover and build new muscle with. 250 blended-source high-energy carbohydrates provide you bulk-calories in the form of usable muscle-energy. 6g multi-source “good” fats provide energy and help in muscle cell development. If you’re trying to pack on size, this is literally your meal ticket.    

The Foundation Series is a line of cornerstone products designed to work synergistically with our Performance line of products and enhance their effects. They are research-backed, stackable and economical.

At some point in every athlete’s career, they need basic, fundamental products in order to achieve their fitness goals. All too often, top tier supplement brands only focus on combination products that contain an assortment of ingredients specifically formulated to produce narrow results. While these products are often good at achieving their intended results, many athletes need custom-tailored formulas for their individual lifestyle and fitness goals. With our Purus Labs Foundation Series™, we've applied the same care and dedication to these more simplistic, individual components that we do to our goal-oriented products. Just as you can trust our proteins, pre workouts and amino products, you can trust our Foundation Series™ products to deliver exceptional results, unrelenting quality and unwavering commitment to our customers' goals and dreams.

Microfiltered Whey Protein Concentrate
Rich in BCAA content and boasting one of the highest Biological Values (BV),104, this has long been the benchmark standard for supplemental protein. It is quickly absorbed, not as quickly as isolate though, making them a great stack.

Micellar Casein
Non-denatured milk protein, micellar casein has a very slow and sustained digestion/absorption rate compared to that of whey isolate and concentrate. Although it doesn’t have the acute effect on plasma amino acid levels that the other two forms do, its sustained digestion feeds your muscles for longer periods.

MCT Fats
MCT fats, or medium-chain triglycerides are healthy fats from coconuts. MCTs help to provide neural and physical energy. They can also help you to feel full longer, and help whey protein to process more slowly, further lowering the chance of a blood sugar spike.

Vitamin Blend
There are a myriad of vitamins listed in the aside nutrition panel for Mass Gain. These vitamins help to balance the body and provide much-needed micronutrients, similar to what you would find in whole foods.

Creatine Monohydrate
Creatine monohydrate has been known to increase work capacity and assist the body in increasing lean body mass.
