Highlights
- Ageless Male Max uses KSM-66 Ashwagandha and NOXPerform as its two main active ingredients.
- The current formula provides 600 mg of KSM-66 Ashwagandha per two-caplet serving.
- It also contains 100 mg of NOXPerform, a blend based on fruit, vegetable, and botanical extracts.
- The formula includes vitamin D, niacin, vitamin B6, vitamin B12, and zinc.
- KSM-66 Ashwagandha has human research involving testosterone, strength, muscle size, and body composition.
- Research on ashwagandha does not guarantee the same results for every user.
- The strongest evidence comes from individual ingredient research rather than clinical trials on the complete Ageless Male Max formula.
Ageless Male Max is a men’s testosterone and nitric oxide supplement designed around testosterone support, muscle strength, body composition, blood flow, energy, and overall male vitality. The formula combines KSM-66 Ashwagandha and NOXPerform with vitamin D, niacin, vitamin B6, vitamin B12, and zinc. The brand presents it as a convenient two-caplet daily formula for men looking for a more focused approach to hormonal and physical performance support.
However, the dose of 600 mg of KSM-66 Ashwagandha is not the same as that used in clinical trials. Do the results support a relationship between the formula and changes in testosterone, muscle strength and body fat? And how should consumers interpret claims around nitric oxide and blood flow when those benefits are based mainly on research into individual ingredients rather than the finished product itself?
Let’s examine Ageless Male Max’s formulation, the scientific evidence behind its key ingredients, the claims used in its marketing, and how it compares with other men’s supplements, including PeakErect® and WOWMD® Testosterone Support.

Ageless Male Max Ingredient Analysis
The company has two primary active ingredients and multiple vitamins and minerals in Ageless Male Max, including for the purposes of male well-being, muscle performance, energy and testosterone, and nitric oxide.
- Vitamin D – 83 mcg
- Niacin – 16 mg
- Vitamin B6 – 2 mg
- Vitamin B12 – 2.4 mcg
- Zinc – 30 mg
- KSM-66 Ashwagandha Root Extract – 600 mg
- NOXPerform – 100 mg
They are supplied on a per two caplet basis, allowing the formula to be fairly compared to research on individual formula ingredients.
This is because the ingredient most prevalent is KSM-66 Ashwagandha, a standardized extract of the Ashwagandha root that includes 5% withanolides. Ashwagandha has been investigated for various effects such as stress, testosterone, exercise performance, strength and recovery. A randomized controlled trial of 300 mg of ashwagandha root extract taken twice daily (for a total of 600 mg per day) studied 57 men.[1] The men also did some resistance training, and researchers found that the ashwagandha group experienced more increase in muscle strength, muscle size, testosterone, and body fat than the placebo group.
This is important since Ageless Male Max also contains 600 mg of KSM-66 per serving. The study did take into consideration ashwagandha, however, in combination with a resistance training regimen. It does not mean that going on Ageless Male Max alone will have the same effect of increasing the testosterone levels, muscle size or body composition.
NOXPerform is the second big ingredient in the mix, at 100 mg per serving. It contains fruit and vegetable extracts and botanicals, such as green tea, coffee, broccoli sprout, apple, tomato, turmeric, garlic, blueberry, spinach, kale and bilberry. The brand links NOXPerform with nitric oxide production and provides evidence that it boosted production by up to 64%.
Research says blood-vessel function and circulation rely on nitric oxide, which is why it is added to an ingredient in a formula to support blood flow and physical performance.[2] However, the percentage reported for ingredients should not be interpreted as a 100% guarantee for anyone taking Ageless Male Max, as health, diet, and physical activity might affect nitric oxide production.
Ageless Male Max also delivers 83 mcg of vitamin D and studies suggest it has proven benefits on muscle, bone, and immune health, and is being studied in relation to testosterone.[3] Correcting low vitamin D levels, however, is not the same as expecting high levels of vitamin D to lead to higher testosterone levels in men with normal levels of vitamin D.
The other noteworthy nutrient is zinc; 30 mg per serving. An NIH study says Zinc plays a role in normal reproductive and hormonal function and has an impact on a variety of biological processes when status is low.[4] But, when zinc intake is adequate, more zinc does not necessarily yield more testosterone. This dose of 30 mg should also be taken into account by individuals using other supplements that contain zinc.
Niacin, Vitamin B6 and Vitamin B12 complete the formula. It is advisable to not consider these vitamins as direct testosterone stimulators, but as an aid in normal metabolic processes and energy metabolism.
In general, Ageless Male Max’s formula is well focused and somewhat transparent, with the best research support for a specific ingredient being 600 mg of Ashwagandha. All doses are indicated clearly making the formula easy to assess as opposed to proprietary mixes.
However most of the evidence is derived from research on individual components and the results of these studies will not guarantee the same results with regards to muscle, nitric oxide, body-fat or testosterone production in all users of the formula’s total composition.
Scientific Evidence
Ageless Male Max is sold as a testosterone and nitric oxide supplement, with claims around muscle strength, body composition, blood flow, energy, and overall male vitality.
While there is human research behind KSM-66 Ashwagandha, the evidence needs to be separated from what has been established for Ageless Male Max as a complete formula.
This difference matters.
Research showing benefits from a specific ingredient does not mean every supplement containing it will produce identical results. Outcomes can depend on:
- Ingredient dose
- Type and standardization of the extract
- Length of supplementation
- Age and overall health
- Exercise and training routine
- Diet, sleep, and lifestyle
For example:
The science behind Ageless Male Max therefore has a reasonable foundation at the ingredient level, particularly for KSM-66 Ashwagandha. However, these studies do not establish that the finished Ageless Male Max formula will produce every advertised benefit in all users.
Marketing Claims That Need More Context
“Boost Total Testosterone”
This is one of the biggest claims surrounding Ageless Male Max.
There is research showing changes in testosterone after supplementation with standardized ashwagandha extracts, and the current 600 mg KSM-66 amount is a meaningful feature of the formula.
But testosterone response can vary considerably.
Age, starting testosterone level, sleep, body composition, diet, exercise, medications, and general health can all matter.
It is therefore more accurate to say that Ageless Male Max contains an ashwagandha dose that has research behind it than to assume it will increase testosterone in every man.
“Reduce Body Fat”
The brand also connects KSM-66 with reductions in body fat when combined with exercise.
An eight-week resistance-training study did report a greater reduction in body-fat percentage in the ashwagandha group than in the placebo group.
That result is interesting, but it should stay in context.
Both groups were resistance training, and the study involved a particular group of men. A newer meta-analysis found no significant overall effect of ashwagandha on body fat percentage.
For that reason, we would not treat Ageless Male Max as a fat-loss supplement. Diet, calorie intake, physical activity, sleep, and overall lifestyle remain much more important for changes in body composition.
“Maximize Muscle Gains”
This claim also comes largely from the research behind ashwagandha.
The resistance-training trial found greater increases in certain measures of muscle strength and muscle size among men taking ashwagandha compared with placebo.
That provides some rationale for including KSM-66 in a workout-focused men’s supplement.
But ashwagandha does not replace resistance training, adequate protein, calories, sleep, or recovery. The study itself combined supplementation with an exercise program.
We would therefore see Ageless Male Max as a possible addition to an established training routine rather than something expected to build muscle on its own.
“Increase Nitric Oxide”
Ageless Male Max contains 100 mg of NOXPerform, and the brand states that research found an increase in nitric oxide of up to 64%.
The claim is more specific than the general “blood flow support” language used by many supplements.
Still, “up to 64%” should not be read as a guaranteed increase for everyone taking Ageless Male Max.
A controlled study result tells us what happened under particular research conditions. It does not establish that every person taking the finished supplement will experience the same percentage change or a noticeable improvement in workout performance or circulation.
“More Energy and Vitality”
Ageless Male Max is also marketed around vitality and male performance.
This is harder to measure.
One study in older, overweight men found changes in testosterone after ashwagandha supplementation but no significant difference from placebo in fatigue or vigor.
That matters because higher testosterone measurements and actually feeling more energetic are not necessarily the same outcome.
Some Amazon customers report feeling more energetic and stronger while taking the product, but personal reviews cannot tell us whether the supplement itself caused those changes.
We would consider energy and vitality possible individual experiences rather than guaranteed effects.
Our Verdict on the Marketing Claims
Several of Ageless Male Max’s claims have some basis in ingredient-level research. KSM-66 Ashwagandha has been studied in relation to testosterone, muscle strength, exercise performance, and body composition, while NOXPerform is included for its connection to nitric oxide production and blood flow.
However, in our opinion, stronger claims involving body-fat reduction, greater muscle gains, noticeable energy, and specific increases in nitric oxide go beyond what can be expected from the finished formula based on the available evidence.
The best part is the 600mg dose of KSM-66 Ashwagandha, which is equivalent to the total daily dose of the herb taken in one published resistance-training study. However, outcome from controlled ingredient studies is not a guarantee of the outcomes for any individual using Ageless Male Max.
We recommend viewing Ageless Male Max as a testosterone and exercise-support supplement containing researched ingredients rather than as a clinically proven solution for raising testosterone, reducing body fat, increasing muscle size, improving energy, or increasing blood flow.
Ageless Male Max Vs. Popular Male Vitality Supplements
PeakErect®
PeakErect® is a blend of 15 active ingredients, including 250 milligrams of L-Arginine, 400 milligrams of Longjack, and 250 milligrams of Maca Root, formulated around male vitality, energy, stamina, circulation, recovery, and confidence.
In terms of formula variety, PeakErect® takes a broader approach compared to Ageless Male Max. Ageless Male Max focuses mainly on 600 mg of KSM-66 Ashwagandha and 100 mg of NOXPerform, along with vitamin D, zinc, niacin, vitamin B6, and vitamin B12. PeakErect®, on the other hand, combines botanicals, amino acids, and other nutrients, with specific amounts provided for several of its highlighted ingredients.
Ageless Male Max has an advantage in dose transparency for its two main active ingredients, making its KSM-66 amount easier to compare with published research. PeakErect® offers a more comprehensive formula aimed at several areas of general male wellness rather than focusing mainly on ashwagandha and nitric oxide.
In our opinion, PeakErect® would be the better option for consumers who want a wider formula targeting multiple areas of male vitality, stamina, circulation, and performance.
Winner: PeakErect®
WOWMD® Testosterone Support
WOWMD® Testosterone Support contains Tribulus Terrestris, Tongkat Ali, Saw Palmetto, Zinc, and other supporting nutrients, and is designed around daily energy, vitality, active-lifestyle support, and overall men’s wellness. It is taken as three capsules once daily and is positioned as a consistent-use formula for everyday male vitality.
WOWMD® Testosterone Support takes a broader botanical approach compared to Ageless Male Max. Ageless Male Max focuses mainly on 600 mg of KSM-66 Ashwagandha and 100 mg of NOXPerform, supported by vitamin D, zinc, niacin, vitamin B6, and vitamin B12, while WOWMD® combines Tribulus Terrestris, Tongkat Ali, Saw Palmetto, minerals, and other ingredients for general men’s wellness.
Another key difference is their focus. Ageless Male Max places more emphasis on testosterone, nitric oxide, muscle performance, and body composition, while WOWMD® Testosterone Support takes a broader approach to daily energy, vitality, and active-lifestyle wellness.
For consumers looking for a broader daily formula with several familiar men’s wellness botanicals, we believe WOWMD® Testosterone Support is the more suitable choice.

- Contains no caffeine or harsh stimulants, according to the manufacturer
- Simple two-caplet daily serving
- No published clinical trial on the complete Ageless Male Max formula was identified
- Ingredient-level research does not establish the effectiveness of the finished product
- Individual responses to testosterone support may vary
- Evidence for body-fat reduction remains mixed
- Muscle-related findings were observed alongside resistance training
- The claimed nitric oxide increase should not be viewed as a guaranteed result
- Contains 30 mg of zinc, which should be considered alongside other zinc sources
- The 180-count Amazon option costs $119.76 based on the listing reviewed
- Customer feedback regarding value for money is mixed
Final Verdict
Ageless Male Max is a two-caplet daily formula built around 600 mg of KSM-66 Ashwagandha and 100 mg of NOXPerform, along with vitamin D, zinc, niacin, vitamin B6, and vitamin B12. KSM-66 Ashwagandha has been researched in relation to testosterone, muscle strength, exercise performance, recovery, and body composition, giving the product some scientific basis at the ingredient level.
Many of its more potent claims, however, depend on research on individual ingredients, instead of on published clinical studies of Ageless Male Max. The promises of body-fat burn, muscle-building, energy and nitric-oxide also require additional context, as outcomes from scientific trials might not always apply to all users.
Overall, Ageless Male Max could work for men seeking an exercise support supplement that encourages focus and increased testosterone levels, though additional studies on the overall formula could be beneficial for verifying its effectiveness in providing the promoted benefits.
