The products whose human growth hormone formulas have undergone double-blind placebo-controlled IGF-1 clinical trials to measure effectiveness are listed below. IGF-1 levels are used to measure the amount of human growth hormone in the body. If a brand 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 human 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.
