The products whose formulas have undergone double-blind placebo-controlled IGF-1 clinical trials to measure effectiveness are listed below.

IGF-1 blood levels are used to measure growth hormone therapy in adults because it reflects whether GH is improving or not. Measuring an actual growth hormone level requires attempted pituitary stimulation using intravenous medications in a hospital setting and blood is drawn every 30 minutes over a period of hours. Such testing is not feasible for an extended clinical trial of a group of patients over a period of months.

PLEASE NOTE: If a brand of product is not listed below it's because that brand has not had any legitimate IGF-1 clinical studies to prove whether it can actually increase growth hormone in the body.

*If you compare the results of Nu-Spring and PRO-Symbio Plus you will notice that it appears they reported some of the same results. For instance, Nu-Spring's patient 4 is identical to PRO-Symbio's patient 2. Perhaps both brands use the same formula.
