#1. Prime Male
Prime Male is #1 because it uses premium-quality, bioavailable ingredients and synergy-within-synergy strategies to unlock off-the-charts T-boosts… with a growing list of raving testimonials saying that it works.
Prime Male uses all 5 of our Best5 Testosterone Boosters, starting with our #1-ranked DAA, shown to boost T 42% in just 12 days.
Prime Male supplies DAA as D-AA-CC, an enhanced form that’s easier to absorb. Prime Male does similar “upgrades” on 11 of its 12 ingredients, opting for the more active, potent & absorbable forms of each one.
The real advancement is how Prime Male brings those ingredients together to amplify each other’s activity and boost T both directly & indirectly:
- Powerful direct T-Boosters like D-AA-CC, Zinc, Mucuna & more
- Achieves multiplying T-Boosts with K2+D3+Magnesium synergy
- Fights T-killing estrogen with 2 compounds for 2X synergy
- Neutralizes T-killing SHGB with 3 compounds for 3X synergy
With these smart formulation strategies, Prime Male unleashes a test-boost so strong that men can finally experience the benefits of higher testosterone: More vitality, stronger sex drive, muscle mass gains, less belly fat, sharper thinking & more.
Prime Male Quality Points
D-AA-CC (premium D-Aspartic Acid), Asian Red Ginseng 4:1 Extract, Mucuna pruriens standardized to 15% levodopa, Nettle Root 10:1 extract, BioPerine®, Boron Amino Acid Chelate, Zinc Citrate, Magnesium Citrate
Formula synergy, potent ingredients & high absorption make Prime Male the most powerful & effective testosterone booster supplement ever developed.
Prime Male is designed for age-related testosterone decline, so it meets the androgen needs of men over 30. It’s not really for younger men. But if you want a test spike so big you can feel it enhancing your life, Prime Male is Best for YOU.

#2. Nugenix Ultimate Testosterone
Nugenix got on our radar with their lousy first-edition Testosterone Booster stack. With Ultimate Testosterone, Nugenix has beyond redeemed themselves with a potent, intelligent stack that includes 3 of our Best 5 Testosterone Boosters.
Nugenix Ultimate Testosterone is driven by a HUGE 3,000 mg serving of DAA. That’s some intense activity! It’s almost double Prime Male’s DAA dosage, but Prime Male gets extra activity by using the superior D-AA-CC form.
We’re impressed by Nugenix Ultimate Testosterone’s herbals. Fenugreek, Mucuna, Stinging Nettle and Tongkat Ali is a great botanical T-booster stack, and 3 of these 4 herbs are presented in enhanced-potency form. The Nettle is plain; would be better if they used a 10:1 concentrated Nettle extract like Prime Male does.
Epimedium sagittatum (Horny Goat Weed) and Maca are off base for T, but both are still excellent manly health herbs, especially for sex drive.
Nugenix Ultimate Testosterone Quality Points
Fenugreek extract standardized to 50% saponins, Mucuna pruriens standardized to 40% L-DOPA, Tongkat Ali 100:1 Extract, Epimedium sagittatum 4:1 extract
Potency. Nugenix does an awesome job of hitting Critical Mass dosages that WILL unlock T-boosting activity. They get there by combining of big mg. sizes, high standardization & super-concentrated extracts to achieve peak T-boost activity.
Nugenix Ultimate Testosterone is for men who want solid T-boosting activity with a side order of sex drive, thanks to the Horny Goat Weed & Maca.

#3. TEST FREAK
The grungy, bright-yellow box gives it away: TEST FREAK is extreme in potency – but so well-formulated that it is our #3-ranked Testosterone Stack for 2016.
TEST FREAK’s main strategy involves Fenugreek… and lots of it. Each serving supplies a big 1,100 mg dose of Fenugreek from two premium branded sources: TESTOFEN® and TRIGOTEST™. Both these quality Fenugreek sources are standardized to supply a broad spectrum of active herbal ingredients.
Fenugreek is good for test… but bad for DHT, another critical manly hormone.
Here’s where TEST FREAK is smart: Along with supersized & advanced Fenugreek, it has a Proprietary DHT Support Complex. So you get Fenugreek’s benefits without sacrificing your DHT. TEST FREAK formulators know what they are doing.
And, like Prime Male, TEST FREAK boost T indirectly – here, with a Proprietary Estrogen Support Complex to keep this T-killing girly hormone in check.
TEST FREAK Quality Points
TESTOFEN®, TRIGOTEST™, Magnesium Citrate, Zinc Acetate.
TEST FREAK is the greatest Fenugreek-driven test-booster on the market, and smartly combines its two Fenugreek forms with pro-DHT compounds.
If you hit the gym a lot, TEST FREAK is a good test booster stack for you. Fenugreek isn’t the best T-booster (it doesn’t make our Best5), but it excels in sex drive and physical performance-enhancement.
Best5 2016 rating for TEST FREAK: 4.5 stars Our Rating
If you’re a serious bodybuilder, TestoFuel is made for YOU.
But what sets TestoFuel apart is that its synergistic T-Booster stack doubles as a physical performance-enhancer… without sacrificing activity on either side.
TestoFuel is driven by a big 2,300 mg dose of DAA. It uses the plain form of DAA (actually, all TestoFuel ingredients are plain), but the hefty dose makes up for it.
Another clever formula trick is that TestoFuel uses the synergistic Zinc+B6+Magnesium testosterone-boosting triad… but supplies them as Pyridoxine HCl, Magnesium Aspartate, and Zinc Monomethionine Aspartate.
Sound familiar? That’s right, sports nutrition fans – TestoFuel’s Zinc, B6 & Magnesium is a mirror-image of the ZMA sports nutrition stack that can enhance muscle strength and muscle recovery – making it appealing to serious weightlifters.
TestoFuel augments the ZMA stack with additional magnesium, zinc and B6 from Oyster Extract. Using oysters reinforces these key nutrients in a natural ratio & bioavailable forms that could unleash extra synergy.
And in another smart move, TestoFuel’s Red Panax Ginseng and Fenugreek are 2-way players that boost testosterone and gym performance at the same time.
These slick formula tricks compensate for the basic ingredient forms used in TestoFuel. What you end up with is an intelligently formulated test-boosting/workout-enhancing stack for fitness-driven younger men.
TestoFuel Quality Points
TestoFuel has great T-boosting ingredients, but supplies them in basic forms. They do get quality points for their accurate ZMA stack-within-a-stack, though.
It’s “no-frills,” but TestoFuel’s nutrient synergy, slick formulation, performance enhancers & ZMA stack are effective for big testosterone & muscle gains.
TestFuel is for serious bodybuilders who are seeking testosterone support that’s customized to boost strength, increase muscle mass & reduce bodyfat.
Best5 2016 rating for TestoFuel: 4.3 stars Our Rating
#5. HighT Black
HighT Black barely squeezes into our Best 5 Testosterone Boosters by merit of innovation: It takes T-Boosters in a direction we think we’ll see a lot more of in 2016.
In terms of testosterone, HighT Black gets its activity from quality forms of the botanicals Fenugreek, Longjack, and Rhodiola combined with some cheaper forms of test-foundation nutrients Vitamin B6 and Zinc.
As a pre-workout, it may be even better – supplying premium forms of PWO standouts beta alanine and arginine. Add raspberry ketones & caffeine, and you’ve got a far-reaching formula that builds on a modest T-boost with energy, fat-burning, strength & performance enhancement benefits.
HighT Black Quality Points
Fenugreek standardized to 50% saponins, Eurycoma Longfolia extract 4:1, Rhodiola Rosea standardized to 3% rosavins, Razberi-K®, AAKG, CarnoSyn® Beta Alanine.
HighT Black’s advantage is that it’s a multi-tasker: A 3-in-1 supplement that’s formulated well enough to bring benefits for test, fat-burning & working out.
Casual gym-goers. HighT Black isn’t super-intense in any one area, but it’s perfect for men who are willing to sacrifice big test gains for the convenience of an all-in-one test/workout supplement.

That wraps up our Best 5 Testosterone Boosters for 2016.
This Best5 list is important because the sad reality is, the Testosterone Booster category is littered with lousy supplements, including many that are scams.
This is a damn shame because when formulated intelligently (see our #1, Prime Male), testosterone booster stacks can work really well – and in doing so, unleash manly health benefits that can enhance your whole life.
All 5 formulas on this list are great T-Boosters, but they’re all different, too:
Prime Male, designed for men over age 30, is by far the best flat-out T-booster.
But the other formulas have their own advantages: TEST FREAK is an amazing Fenugreek formula, Nugenix merges test & sex, TestoFuel is great for T+Mass gains, and HighT Black is a 3-in-1 test/fat-burner/PWO formula.
Although Prime Male is on a whole different level of sophistication in terms of formulation strategy, any of these 5 is a strong T-booster stack for 2016.
If you buy a T-booster outside of this list – take the time to do your research and learn How to Buy a Good Supplement.
There are just way too many dud T-Boosters on the market, and we don’t want you wasting your money (or risking your health).
Our BIG List of T-Boosters offers some more insight on what kind of ingredients are used in test stacks, which ones work, and why they are effective.
