How Does TestMax HD Work?

TestMax HD is a potent mix of high potency natural ingredients that improve male sexual performance.

The formula stimulates the synthesis of more testosterone leading to more muscle mass for a bulky ripped physique.

TestMax HD also combines some high potency aromatase inhibitors with Sex Hormone Binding Globulin leading to significant suppression of estrogen synthesis.

Less estrogen means a more conspicuous manifestation of male features.

Lastly, TestMax HD is also enriched with B vitamins and caffeine for mood stabilization.

Caffeine is also thought to improve cognitive and memory functions.

TestMax HD Ingredients – Are They Safe & Effective?

The male performance enhancement supplement is made of naturally sourced and thoroughly tested ingredients.


A natural booster of endothelial nitric oxide leading to improved blood circulation. L-citrulline is also said to enhance post-workout recovery time. A post in the Journal of Urology[1] suggests that L-citrulline improves erection hardness in males with mild ED. Also, we have discussed about this ingredient in our ProShred Elite reviews.


L-arginine is an amino acid that enhances the synthesis of testosterone, the primary male sex hormone. It is also the precursor of nitric oxide, an integral component of the male erectile function. According to the Journal of Psychosexual Health[2], L-arginine boosts male libido and overall sexual performance.

Diindolylmethane (DIM)

A study by Oregon State University[3] has established that diindolylmethane lowers estrogen levels by antagonizing its synthesis. As an aromatase inhibitor, DIM is combined with other ingredients to lower the concentration of Sex Hormone Binding Globulin (SHBG). It also increases the concentration of free testosterone in circulation.

N-acetyl cysteine

N-acetyl cysteine is derived from L-cysteine. N-acetyl cysteine has a range of health benefits. For instance, it’s a powerful antioxidant that protects the body against carcinogenic free radicals. According to a research study available in the International Journal of Fertility & Sterility[4], N-Acetyl cysteine was found to boost testosterone levels significantly. Of course higher T level implies more muscle mass and strength for exercise endurance.

TestMax HD Review – Final Verdict

TestMax HD is highly efficacious, as indicated by third-party laboratory test results available on the official website.

The formula boosts testosterone levels leading to more lean muscle mass.

Increased T level improves muscle mass and improves male sexual performance.

A combination of diindolylmethane and Sex Hormone Binding Globulin inhibitors reduces estrogen to negligible levels.

The formula also has L-citrulline for improved blood flow and faster post-workout recovery.

On the downside, it has no free trials. You get to experience the potential benefits or side effects of the supplement only after ordering some.

Moreover, the product is sold only on the official website, something that limits competitive pricing.

Even so, TestMax HD can be a great product for anyone looking to improve their sexual performance and physique.

    Results May Vary But I Didn't Witnessed Any Improvements.
    I tried TestMax HD and didn’t experience any improvements to my testosterone levels. I understand that TestMax is a dietary supplement and that my results may not be typical. I feel that I was scammed because the product doesn’t work.
