Next, we turn to more company-specific considerations, namely cost and customer service. While they may not work for everyone, testosterone-boosting supplements can potentially improve total or free testosterone levels in men with clinically low testosterone levels or specific nutritional deficiencies. And we've become customers of all the top testosterone boosters on the market today, comparing their products and services. That’s a sad reality of the testosterone booster market, but there are still nine products to consider between our recommended options and those in the top tier just below them. While there are testosterone boosters that cost less, none are a better value than Innerbody Labs, and subscribing saves you 15%-40%. Research-based doses of KSM-66 ashwagandha, fenugreek, zinc, tongkat ali, vitamin D, maca, and more create a powerful formula to increase testosterone and help men build and retain muscle, improve libido, boost energy and mood, improve sleep, and reduce stress. It includes only ingredients shown in scientific studies to boost testosterone and address common symptoms of low T, and it includes those ingredients in the relevant doses for effectiveness and safety.
In this comprehensive guide, we’ve carefully selected the best testosterone boosters for men in 2025 based on clinical research, ingredient transparency, safety, user feedback, and overall performance. Low energy, reduced drive, and slower recovery — these are not just signs of aging, but potential indicators that your testosterone levels may be dipping below optimal. Some may have noticeable benefits only in people with fertility issues or low testosterone levels. Seeing a specialist, such as a urologist, is the best way to find testosterone-boosting solutions that will work.
"As a man in my early 40s, I started to feel my energy levels and strength decline, especially at the gym.

Our lowest tier is reserved for supplements that have significant shortcomings in their formulas, as well as pricing that often doesn't reflect what you should save by making those formulary sacrifices. As it is, these two ingredients from Momentous cost almost as much as the entire bottle of Testosterone Support from Innerbody Labs, which contains the same 400mg dose of tongkat ali, 10mg more zinc, and nine other useful ingredients at clinically relevant doses. But it only recommends 15mg of zinc, which may be a little light for some men, especially if low zinc levels are significantly impacting their testosterone production. Given that something like Innerbody Labs Testosterone Support boasts superior ingredient selection and doses for a similar cost — even less with its highest subscription tier — you can see why Primal-T fell to its current position.
All of its doses are clinically relevant, but none of them are the potentially unsafe megadoses you’ll sometimes see other companies provide. Some testosterone boosters combine a handful of well-researched ingredients with lesser-known botanicals that have plenty of anecdotal history but little scientific rigor to back them up. Others, like Nugenix, include a few of those ingredients at proper doses but alongside others with much less scientific support. At the end of 12 weeks, he’d more than doubled his free and total testosterone, moving from a near clinical deficiency to the high range of normal.
That said, it also contains enough ashwagandha and zinc to potentially boost testosterone. It contains just five ingredients, one of which lacks enough scientific support for us to believe it’ll make a major difference in testosterone levels. However, few boast all three problems (we saved those for our bottom tier), so there are some instances where relative simplicity and reasonable pricing make for simply mediocre products that could have made the top tier if they’d cost less.
EndoPeak just dropped a few months ago but man, it has really gained some momentum. TestForm-X by PureForm Nutraceuticals is made in the USA and uses key testosterone promoting, natural ingredients and uses a science-backed formula, which is why it’s jam-packed with nearly 1,300mg per serving.
