Momentous technically doesn’t have a dedicated testosterone booster complex like the other companies in our guide. Despite these shortcomings, 1st Phorm prices its supplement like a premium product, charging $62 for a one-time purchase and $60 for a subscription. Its only mineral inclusion is calcium, which hasn’t been connected with testosterone in the literature. It costs a one-time fee of $100, but it knocks an extra 15% off most products, bringing the cost of Test+ down to just $45/month. That said, if you find that Xendurance has other products you’re interested in, it might benefit you to become a member with the company. You could use it from time to time alongside a more streamlined T booster, like Roman T Support, but it’s not a solid choice as a T booster on its own. My approach is to use them cyclically – taking breaks every few months to let your body reset. This includes total testosterone, free testosterone, estradiol, and liver function tests. Sleep disturbances are another possibility – some ingredients can be stimulating. Granted, these are purely anecdotal results, but they still help illustrate the potential this supplement offers to regular men who aren’t bodybuilders or even very serious athletes. Coming out of a particularly stressful time in his life, our managing editor, whose tests had revealed near-clinical testosterone deficiency for years, decided to take our supplement regularly for 12 weeks to see what would happen. In doing so, we’re able to deliver what we feel to be more effective doses of the more promising ingredients while keeping the final cost lower for you. Our supplement provides relevant doses of every key ingredient. In some cases, we also included ingredients designed to maximize the potential of our testosterone-boosting ingredients (like black pepper extract, which doesn’t boost testosterone but does improve the absorption of other ingredients).40 After spending the better part of a decade researching low testosterone and the different ingredients various companies use to address it, we’ve learned which ones should work and which ones probably won’t. Injectable testosterone can cause mood problems and other effects from dramatic swings in testosterone concentrations.36 And gels and creams can leave a residue and transfer to women and children. Our experts weigh in on testosterone supplements and reveal whether they work to improve low T. Innerbody uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. If your testosterone levels are too low, it's possible that Viagra and similar prescription ED medications might not work. If your test results show testosterone levels below the normal range or your symptoms are significant, you should seek treatment beyond simple dietary adjustments. With the other ingredients, several of the doses are substandard compared to successful small-scale studies. They come from a handful of companies and consist of many ingredients similar to those you might find in a testosterone-targeted supplement. There are reported instances of early-onset puberty and unexpected hair growth in children unknowingly exposed to testosterone-boosting gels.58 But if you exercise caution and use thorough cleansing practices, you and your loved ones should be safe. You’ll want to watch for some additional side effects, if only to give yourself peace of mind; should you experience one of them, you'll know where the problem originated. Only free testosterone truly matters for most low T concerns, and it typically makes up just 2-5% of your total testosterone. The essential difference between free and total testosterone is that total testosterone measures both free testosterone and testosterone that’s bound to proteins like SHBG. Some research will point toward an ingredient’s ability to boost total testosterone, but this doesn’t necessarily mean it will yield any of the benefits you’d want from a testosterone booster. One confusing topic in the testosterone sphere is the difference between free and total testosterone.
