This is up there with any of the rival proteins on the market. Great tasting and does what it says on the tub. Do your loading phase then Take twice a day 2 scoops-taking after a hard work out is essential. Some people do more scoops, but I want my product to last. If you want the best value and can afford it try and buy the 6kg tub. If you train hard and eat right this product is for you. I've got the urge to work out every day now and stay on the taste is a big factor for you like me, then this is for you. Nice with water or milk. I've put on about 4/5 pounds in 4 weeks with the 2kg tub, gonna start my new 6kg next week and expect to at least double that in weight. Aiming to be 13 stone () I will get there thanks to hyperbolic mass and training hard.
The efficiency of human muscle has been measured (in the context of rowing and cycling ) at 18% to 26%. The efficiency is defined as the ratio of mechanical work output to the total metabolic cost, as can be calculated from oxygen consumption. This low efficiency is the result of about 40% efficiency of generating ATP from food energy , losses in converting energy from ATP into mechanical work inside the muscle, and mechanical losses inside the body. The latter two losses are dependent on the type of exercise and the type of muscle fibers being used (fast-twitch or slow-twitch). For an overall efficiency of 20 percent, one watt of mechanical power is equivalent to kcal per hour. For example, one manufacturer of rowing equipment calibrates its rowing ergometer to count burned calories as equal to four times the actual mechanical work, plus 300 kcal per hour,  this amounts to about 20 percent efficiency at 250 watts of mechanical output. The mechanical energy output of a cyclic contraction can depend upon many factors, including activation timing, muscle strain trajectory, and rates of force rise & decay. These can be synthesized experimentally using work loop analysis .
