About the JYM Testosterone Booster: Like every one of the JYM Supplement Science products, Alpha JYM is a non-proprietary supplement that uses the proper amounts of each ingredient and lists them clearly in the supplement facts panel. Each of the six ingredients were chosen based on real scientific data published in peer-reviewed journals and our experience with clients in the gym. These six ingredients work to support your body's natural levels of testosterone through five different processes. When you read the label of Alpha JYM, you'll see that it provides a total of 2100 mg (2.1 grams) of active ingredients per serving. When you take it twice per day as recommended, it delivers a total of 4,200 mg (4.2 grams) of active testosterone-optimizing ingredients. These ingredients don't include common vitamins and minerals like vitamin D and zinc, like many “testosterone optimizers” provide. Why? Because it is more beneficial to get your vitamins and minerals separately. Alpha JYM Features studied ingredients provided in their effective amounts
