Testerone XL is a test-booster supplement.

It aims to increase muscle mass, lose body fat, and improve workouts by improving testosterone levels.

Ingredients Label

Active Ingredients

Zinc

Zinc is a mineral involved in many enzymes in the body.

It’s been shown to increase testosterone levels in people with Zinc deficiencies (1) as well as maintain testosterone in athletes after exercise (2).

The recommended dose is 15 mg, but athletes may benefit from larger amounts.

Magnesium

Magnesium is an essential mineral that has been shown to increase sleep quality.

Higher quality sleep has been linked to higher testosterone levels (3, 4).

The effective dose is about 50mg .

Vitamin B6

Vitamin B6 has the ability to increase Zinc absorption (5).

D-Aspartic Acid

D-Aspartic acid has been shown to increase testosterone levels in males over a short period (about 1-2 weeks). This effect, however, only continues in infertile men (6).
The effective dose is about 2000-3000 mg daily.

Tribulus Terrestris

Tribulus Terrestris is a plant often used for libido enhancement.

It has long been believed to increase testosterone, but studies have failed to show this (7). There may be a small improvement in infertile men (8).

Who Takes It?

Testerone XL would be of most benefit to older males, or men with low testosterone levels.

How to Take

Take 2 capsules 250 mL water daily.

Side Effects

An increase in libido is common with all ingredients in Testerone XL.

Mood may change with changes in hormone levels.

Pros

• The ZMA and D-Aspartic acid components of Testosterone XL are tried and tested testosterone boosting ingredients.

Cons

• Tribulus has proven ineffective for boosting testosterone
• Effects from D-Aspartic acid may fade after only 1 or 2 weeks of use.

Conclusion

Testerone XL is a basic formula whose effects will only be optimal for the first 2 weeks of use, before fading to a somewhat regular ZMA supplement.

It may improve testosterone and sleep quality, but perhaps not as well as many other T-boosters.
