Testosterone boosters are supplements that aim to support healthy testosterone levels with vitamins, minerals and herbs. Their realistic job is narrower than the marketing suggests: correct common shortfalls in vitamin D, zinc and magnesium, and add ingredients with some human evidence, such as D-aspartic acid, ashwagandha and fenugreek.
We have reviewed more than 15 test boosters and scored each on the same four tests. Here are our top seven, starting with the best overall formula.
Quick verdict
Testogen Ultimate is our top pick: 13 fully disclosed ingredients, including 2,025 mg of D-aspartic acid, KSM-66 ashwagandha and 4,000 IU of vitamin D3, with zinc, magnesium and boron and a 100-day money-back guarantee. If your main goal is building muscle, Brutal Force DBULK is our pick, and TesTotal is the great value choice at about 90 cents a day on its five-month pack.
Testosterone boosters pros and cons
What we like
- Vitamin D, zinc and magnesium matter most for men who are short of them
- KSM-66 ashwagandha has trial evidence for strength and testosterone in men who train
- The best formulas list every dose on the label
- Stimulant-free options can be taken at any time of day
What could be better
- Most boosters cannot raise testosterone that is already normal
- Many products hide their doses in proprietary blends
- Results take weeks and depend on sleep, training and body weight
- Symptoms of low testosterone call for a blood test, not just a supplement
How we ranked them
Every product is scored out of 10 on four tests: formula and dosing (35%), ingredient evidence (25%), label transparency (20%) and value and terms (20%). Our first three picks cover three different goals: the best overall formula, the best for building muscle and the best value. From number four, the list is ranked by score. Our picks are scored on the same scale as every other product, and the full method is on our how we rate page.
1. Testogen Ultimate: best overall
Testogen Ultimate scores 9.3 out of 10, the highest of any test booster we have reviewed. Its four capsules contain 2,025 mg of D-aspartic acid, 200 mg of KSM-66 ashwagandha, Korean ginseng, fenugreek and nettle root, plus 4,000 IU of vitamin D3 with K2, 25 mg of zinc, 100 mg of magnesium, 5 mg of boron and vitamin B6. All 13 doses are on the label, and it is stimulant-free.
It costs $69.99 a month, or $41.99 a bottle on the five-month pack, with a 100-day money-back guarantee. Read our Testogen review.
2. Brutal Force DBULK: best for muscle building
DBULK is not a testosterone booster in the strict sense. It is a stimulant-free bulking support capsule for people who lift, so it is our pick if your real goal is muscle. Its three capsules provide 800 mg of MSM and 30 mg of sodium hyaluronate for joint comfort under heavy training, with 300 mg of leucine, 200 mg of ashwagandha root, 200 mg of suma root and 75 mg of tribulus, all disclosed on the label. We score it as a muscle and fitness supplement, at 7.9 out of 10.
Its doses are moderate, so it works best as support for the basics that build muscle: a calorie surplus, enough protein, creatine and progressive training. One bottle costs $44.99, or $89.98 for three on the buy-two-get-one-free offer, about $1 a day. Read our DBULK review.
3. TesTotal: great value
TesTotal scores 7.6 out of 10 and is our great value pick. Its two capsules provide 1,176 mg of D-aspartic acid with 1,040 IU of vitamin D3, 100 mg of magnesium, 5 mg of zinc and 10 mg of vitamin B6, and every dose is on the label. Its fenugreek, red ginseng and nettle (20 mg each) and its boron are well below the amounts studied, so think of it as an affordable daily basics formula rather than a premium booster.
It costs $44.99 a month, $29.99 a bottle on the three-month pack and $26.99 a bottle on the five-month pack, about 90 cents a day, which makes it one of the most affordable test boosters we have reviewed. The 100-day money-back guarantee applies to multi-month orders. Learn more at testotal.com.
4. Prime Male Vitality: closest rival
Prime Male scores 8.5 out of 10. Aimed at men over 30, it combines 1,600 mg of D-aspartic acid, 300 mg of KSM-66 ashwagandha, nettle root, Korean ginseng and luteolin with 4,000 IU of vitamin D3, 25 mg of zinc, magnesium and boron, taken as four capsules spread through the day. It is one of the pricier options in the category. Read our Prime Male review.
5. T-Hero: longest guarantee
T-Hero scores 8.4 out of 10. Its two capsules provide 600 mg of ashwagandha, the top of the research range, with 500 mg of shilajit, 100 mg of DIM and 5 mg of boron. It costs $39 a month and comes with a 365-day money-back guarantee, the longest we have seen. Read our T-Hero review.
6. Hunter Test: highest doses
Hunter Test scores 8.3 out of 10. Its six capsules contain 3,000 mg of D-aspartic acid, 300 mg each of ginseng and ashwagandha, 200 mg of indole-3-carbinol, 30 mg of zinc and 10 mg of boron, some of the highest doses on this list. Its 5,000 IU of vitamin D3 is above the 4,000 IU daily upper limit for adults, and six capsules a day is a lot to take. Read our Hunter Test review.
7. Mars Men Boost: best tongkat ali formula
Mars Men Boost scores 8.2 out of 10. It is built around 500 mg each of tongkat ali, shilajit, fenugreek and cistanche, with 750 mg of taurine, 4,000 IU of vitamin D3, vitamins K1 and K2, 30 mg of zinc, copper and 10 mg of boron. It costs $59 a month. Read our Mars Men review.

What testosterone boosters can and cannot do
Testosterone falls gradually with age, and carrying extra weight, sleeping badly and running low on vitamin D or zinc can all push it down. A good booster can help where a shortfall exists, and ingredients such as KSM-66 ashwagandha have trial evidence for strength and testosterone in men who train. What no supplement can do is lift normal levels far above the normal range.
If you have symptoms such as persistent low energy, low libido or loss of muscle, ask your doctor for a blood test. Low testosterone can have medical causes that a supplement will not fix.

Frequently asked questions
What is the best testosterone booster?
Testogen Ultimate is our top-rated test booster, with a score of 9.3 out of 10. It combines 2,025 mg of D-aspartic acid and KSM-66 ashwagandha with vitamin D3, zinc, magnesium and boron, and lists every dose.
Do testosterone boosters really work?
They can help when testosterone is held back by a shortfall in vitamin D, zinc or magnesium, and some ingredients, such as KSM-66 ashwagandha, have trial evidence in men who train. They will not raise normal testosterone far above the normal range, and results take weeks.
What is the best testosterone booster for muscle growth?
If building muscle is your main goal, our pick is Brutal Force DBULK, a stimulant-free bulking support capsule, used alongside a calorie surplus, enough protein, creatine and progressive training.
What is the best cheap testosterone booster?
TesTotal is our great value pick. It covers vitamin D3, zinc, magnesium and vitamin B6 with 1,176 mg of D-aspartic acid, and costs about 90 cents a day on its five-month pack.
Are testosterone boosters safe?
Most ingredients in these products are well tolerated at label doses. Check your total vitamin D and zinc if you take other supplements, and speak to your doctor first if you have a medical condition, take regular medication or are being treated for low testosterone.
Final verdict
A good test booster supports the basics behind healthy testosterone rather than promising a transformation. Testogen Ultimate does that most completely, which is why it is our top pick, with DBULK for men focused on muscle and TesTotal for anyone who wants the essentials at a lower price.
