Dr. Delgado did the studies on himself, and on some of his patients to get independent confirmation of results found at the university.  The university scientists involved knew exactly what tests to measure to determine whether the product was truly working or not. 

Well the fascinating news reported by Dr. Delgado after he measured his human growth hormone level compared to past tests all the way to current - his human growth hormone level never exceeded .5 - his levels were typically as low as .1 or .02 ng/ml. These deficient or low levels are typical for a person past the age of 40.  However a youngster generally has a level that ranges somewhere in between 2 and 5 and up to 8 or 10 along with IGF-1 levels over 350 ng/ml. 

     Dr. Delgado had used a well known injectable growth hormone two years prior for six months.  This made it easy for him to compare lab differences and the benefits he experienced while taking actual growth hormone.  And for nearly one year he had been off human growth hormone, and no form of other supplements for a period of three months at the time they were comparing clinical results.  He started checking his human growth hormone level, to get a base line and then he used the oral spray product for five days, spraying every morning, midday, early evening prior to dinner and again just before bed.  They then repeated the challenge test measuring his human growth hormone levels every half-hour, for two hours.  He also had my IGF-1 level rechecked.  They found that after five days of using the Grow Young product, his human growth hormone level, increased rather dramatically to a level that Dr. Benner the endocrinologist would say that is a true test of the human growth hormone to absorb into the body.  Dr. Delgado's level went up five times his original baseline level using the oral spray compared to before when he had not been using any product.
