7-Keto® DHEA has been the subject of clinical research studies and has proven to be safe and effective for weight and fat loss; three times more effective than diet and exercise alone. We combined 7-Keto® with the synergistic benefits of standardized green tea extract rich in EGCG and chromium for maximum weight and fat loss benefits. 7 Keto is a metabolite of, and not a precursor to, DHEA and therefore doesn’t increase DHEA, testosterone or estrogen levels.
