A group of 43 men aged 27-37 years were divided into two groups: 1) the active Testosterone Booster compound group and 2) an indistinguishable placebo group. All subjects consumed their test product every morning at breakfast for 12 consecutive days, and blood samples were taken before treatment, after 6 and 12 days of treatment, and 3 days after stopping treatment. All blood samples were drawn between 9:30-10:30 am, a time of day when serum oscillations of testosterone are at their minimum. Results showed that serum testosterone levels in the active group were significantly increased compared to those of the placebo group over the course of the study, wherein the active Testosterone Booster compound led to a 42% increase in testosterone after 12 days of use. Interestingly, 3 days after the suspension of treatment, testosterone was still increase 1.22 fold compared to baseline in the treatment group, showing a lasting effect.
CLINICALLY TESTED HORMONE SECRETAGOGUE MAXIMUM STRENGTH FORMULA*
682% MEAN INCREASE IN SERUM LEVELS*
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 Growth Factor-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 hormone levels, and the results were independently analyzed. The results: the GF-9 blend led to a 682% increase in serum hormone levels at 120 minutes, which was significant above and beyond placebo.*
