The health benefits that have been quoted ARE by having increased levels of hGH or IGF-1 in the body. If this can be produced by Promino plus instead of having synthetic hGH injections there is no difference how it got there except there are no bad side effects by real, produced in your body hGH, unlike the synthetic hGH witch does have side effects. I also have been using it and have noticed a lot more energy and I feel more pumped and lot 2-3 pounds last week and have had an increate in positive results in the gym. Have you had any personnel experience with it or is just something you have read? I will be having a blood test soon to find out how much the IGF-1 levels have gone up. I will let you know when I do.
