“Without a doubt, the most well known of all the growth factors is IGF-1 or Insulin-like Growth Factor 1. This is the powerful anabolic hormone taken by many athletes to increase lean muscle tissue. It is also the main reason for athletes taking growth hormone, as this results in higher levels of IGF-1. An anabolic state is the main desire of most bodybuilders and this is the domain of IGF-1. Increased cell division and increased protein synthesis, stimulation of wound healing, production of immune cells, reduction of insulin demand and increased burning of fat, these are the functions of this hormone. Also anti-catabolic, as demonstrated in several pathological states, IGF-1 is the most anabolic of all the growth factors present in whey”
"In summary, independent medical studies have determined that the growth factors present in whey and colostrums have the following functions:
1.Regenerate and accelerate normal growth of aged or injured muscle, bone, cartilage, skin collagen and nerve tissue.
2.Build and retain lean muscle.
3.Burn fat for fuel instead of muscle tissue whilst restricting calories.
4.Regulate blood sugar.
5.Repair DNA and RNA.
8.Help regulate brain chemicals such as serotonin, thereby providing alertness, better focus and positive attitude"
Is getting Whey Concentrate really the BETTER choice even though it contains more lactose?
