In a recent, randomized, cross-over, double-blind clinical trial, men and women between 18 and 70 years of age were recruited. Subjects were scheduled for two testing sessions a week apart where, after an overnight fast, blood samples were drawn over a period of 120 minutes after consumption of either the proprietary GF-9 blend or placebo capsules. Neither the subjects nor the investigators knew at which session the subjects received the GF-9 blend and at which session they received the placebo. At the end of the study, the samples were tested for serum HGH levels, and the results were independently analyzed. The results: the GF-9 blend led to a 682% mean increase in serum HGH levels at 120 minutes. (p=0.01 vs. placebo) HGH has been associated with:
