Performance Lab SPORT T-Booster Review – Clean, Clinical Masculinity Maximizer Excels

Performance Lab SPORT T-Booster’s four-ingredient, multi-pathway strategy may deliver bigger testosterone benefits than formulas twice its size. Let’s find out why this clean, clinical T-booster is greater than the sum of its parts in our Performance Lab SPORT T-Booster review.

17% T-Boost + 42% T-Boost = Peak Manly Performance

Performance Lab SPORT T-Booster only uses four ingredients, but their potency – and how they seem to amplify each other’s effects – add up to a big boost for testosterone and masculinity in men across all age groups.

Let’s take a closer look at the four manliness-enhancing ingredients and how they work together in Performance Lab SPORT T-Booster.

D-Aspartic Acid Calcium Chelate (D-AA-CC), 1000 mg

If you have read other testosterone booster supplement reviews on Best5, you already know that DAA is our top-ranked T-booster ingredient. It’s even better as the chelated form — D-AA-CC — found in Performance Lab SPORT T-Booster.

DAA works like a sex hormone supercharger. It signals the endocrine system at several stages to increase sex hormone production, and then signals to accelerate the rate of sex hormone release.

**Because it affects all sex hormones, it is important to take DAA with an estrogen-blocker to achieve maximum T-boosts. More on that in a minute.

Ashwagandha (KSM-66®, 5% withanolides), 300 mg

DAA gets the top billing in Performance Lab SPORT T-Booster, but KSM-66® Ashwagandha is key for this formula’s success. KSM-66® is the good stuff — organic, standardized ashwagandha backed by human research.

One human research study found KSM-66® increased testosterone levels by 17%:

KSM-66 ashwagandha in Performance Lab SPORT T-Booster has been shown in human research to help raise testosterone levels by about 17%.

Research has also suggested that Ashwagandha:

  • Improves resistance to stress. Stress-induced cortisol hormone is a T-Killer
  • Supports T-Helpers: luteinizing hormone and follicle stimulating hormone
  • Boosts male sex drive, which may be related to its testosterone effects and is a popular benefit for all men, from those in their 20s to men over the age of 50.
KSM-66® Aswagandha is used in testosterone supplements, but also appears in sports nutrition supplements for anabolic muscle growth, pre-workouts, and brain-boosting nootropics.

In addition to increasing testosterone, KSM-66® is an overall masculine performance enhancer — and appears to be Performance Lab SPORT T-Booster’s true driving force.

Mucuna Pruriens (15% levodopa), 150 mg

This herbal testosterone booster naturally supplies levodopa, which is a key player in the body’s testosterone synthesis process.

Basically, Mucuna Pruriens’ levodopa promotes brain –> endocrine system –> testes signaling that ultimately stimulates production of testosterone.

  • Some research has linked Mucuna supplementation to significant increases in both testosterone and luteinizing hormone.

In addition, Mucuna may help to:

  • bump up growth hormone for extra anabolic activity
  • block the feminizing effects of the girly hormone prolactin.
  • improve male virility, including sperm count and sperm activity

Many Mucuna benefits are geared for enhancing masculine health and performance, making it a strong choice for Performance Lab SPORT T-Booster.

Luteolin (from orange fruit extract), 30 mg

Performance Lab SPORT T-Booster’s final ingredient, Luteolin, has emerged as one of the more popular natural aromatase inhibitors used in testosterone supplements. Aromatase is the enzyme that transforms manly testosterone into girly estrogen.

Luteolin’s aromatase-blocking activity helps maintain and sustain circulating testosterone; at the same time it helps keep estrogen levels in check — helping men to keep a more masculine testosterone-to-estrogen ratio.

Plus, luteolin’s anti-estrogen activity helps the sex hormone supercharger DAA to work better — enabling it to selectively raise testosterone without raising estrogen at the same time.

  • This DAA+Luteolin synergy indicates that the formulators behind Performance Lab SPORT T-Booster know what they are doing, and are stacking the right ingredients for maximum testosterone results.

Formula Analysis

Some T-Boosters try to do a million things. Performance Lab SPORT T-Booster instead tries to do one thing — raise testosterone levels — to maximum effect.

With only four ingredients, Performance Lab SPORT T-Booster has more room to play with in each capsule, allowing for hefty dosages of each one.

By using advanced forms, Performance Lab SPORT T-Booster then packs more potency into each dose. This maxes out each ingredient’s T-boosting potential.

  • Performance Lab SPORT T-Booster’s four ingredients also work especially well together, as a synergistic masculine stack.

When combined, they boost many aspects of testosterone production from multiple angles, as well as improving manly performance factors (things like muscle growth, virility, energy, sex drive, etc).

In addition to boosting testosterone and masculine factors, Performance Lab SPORT T-Booster neutralizes T-Killers and feminizing factors like prolactin, stress, aromatase and estrogen.

Supporting T-Helpers and fighting T-Killers, the Performance Lab SPORT T-Booster formula appears to be designed for potent testosterone synergy.

Who Takes It?

Performance Lab SPORT T-Booster is positioned as a sports nutrient, which makes it seem like it would be taken by bodybuilders and athletes. While it is a good choice for that demographic, it is equally good for men over age 40 — especially due to its strong potency and extra sex drive support.

Really, Performance Lab SPORT T-Booster is for any man who wants their supplement to prioritize testosterone and succeed — as opposed to complex test stacks with a lot of small-dosed ingredients that try to do too many things (and fail).

Note: Performance Lab SPORT T-Booster should not be taken by women. As per the manufacturer, it is designed specifically for men’s bodies and may be associated with a greater side effect risk in women.

Performance Lab SPORT T-Booster Benefits

Performance Lab SPORT T-Booster is laser-focused on testosterone and masculine performance. Its benefits:

  • Improved muscle mass development
  • Enhanced training intensity and athletic performance
  • Better libido, erectile strength, virility and sex performance
  • Higher energy levels, both physical and mental
  • Fat loss support and better overall body composition

Like other top-ranked testosterone supplements, Performance Lab SPORT T-Booster may also deliver more general masculine vitality benefits that are associated with a rise in testosterone.

Any Side Effects?

Performance Lab SPORT T-Booster uses just 4 ingredients, all of which have been shown to be well-tolerated in research. It also uses high-quality forms of those T-boosters, in the right dosage ranges.

With its clean, quality label, Performance Lab SPORT T-Booster looks like a safe testosterone supplement with little risk of side effects.

Performance Lab SPORT T-Booster has a clean label.

It is worth noting, the manufacturer suggests cycling Performance Lab SPORT T-Booster on a 4-weeks-on, 2-weeks-off schedule, which might make it even safer and more effective.
