Ashwagandha (KSM-66®, standardized for min. 5% withanolides),
300 mg

Ashwagandha is an Ayurvedic root herb traditionally used for physical and mental performance enhancement. Ashwagandha’s active withanolide compounds may help to help increase testosterone levels by:

  1. Strengthening resistance to stress-induced testosterone decline by optimizing the Hypothalamic-Pituitary-Adrenal (HPA) axis and regulating cortisol release;
  2. Stimulating Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), which signal for testosterone production and release;
  3. Supplying targeted antioxidant activity to fight free radicals that attack and degrade testes, testosterone and sperm.

The KSM-66® form of ashwagandha in Performance Lab® Sport T-Booster has been clinically shown to:

L-Citrulline supplementation has been associated with improvements in time-trial cycling competition in clinical research:

About KSM-66® Ashwagandha:

KSM-66® is the strongest full-spectrum ashwagandha root extract on the market today – standardized for 5% withanolides and supplying all natural constituents and cofactors. KSM-66® is also the only branded ashwagandha that is 100% Organic Certified.

D-Aspartic Acid Calcium Chelate

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

D-Aspartic Acid Calcium Chelate (D-AA-CC) is an advanced chelated form of D-Aspartic Acid (DAA), an amino acid that helps regulate the synthesis and release of sex hormones.

DAA is believed to work by orchestrating hormone signaling throughout the endocrine system’s glands, thereby playing a role in sex hormone synthesis and release. DAA has been suggested to support testosterone production by:

  1. Stimulating the pituitary gland to increase production of luteinizing hormone (LH) and growth hormone;
  2. Stimulating the hypothalamus gland to release gonadotropin-releasing hormone (GnRH), which in turn signals for synthesis of additional LH and Follicle Stimulating Hormone (FSH);
  3. LH and FSH then signal the testes to increase production of testosterone and sperm, respectively.

One study found that a 12-day DAA protocol was associated with a 42% increase in blood testosterone and a 33% increase in luteinizing hormone (LH):

About Performance Lab® Sport T-Booster D-AA-CC

D-AA-CC binds DAA molecules to calcium chelate in order to improve absorption and digestive comfort. D-AA-C’s higher bioavailability supplies more activity in smaller dosages, helping to minimize gastric side effects that may be associated with larger doses of plain DAA.

Performance Lab Sport® T-Booster’s 2X Cortisol Control: KSM-66® + Mucuna Pruriens

High levels of the stress hormone cortisol have a significant negative effect on circulating testosterone. Performance Lab® Sport T-Booster targets cortisol with KSM-66® Ashwagandha and Mucuna: Anti-stress adaptogen herbs that are clinically shown to balance blood cortisol levels.

T-Booster’s 2X anti-cortisol design helps circulating testosterone to stay more active for a longer duration – extending its support for muscle development and masculine health.

Mucuna Pruriens (standardized for min. 15% levodopa),
150 mg

Also called velvet bean, Mucuna Pruriens is an Ayurvedic masculinity tonic that supplies an active ingredient called levodopa (L-DOPA). L-DOPA supports masculine health by starting a chain reaction of bioactivities that culminate in testosterone production:

  1. L-DOPA stimulates the brain to release gonadotropin-releasing hormone (GnRH);
  2. GnRH signals the pituitary gland to produce luteinizing hormone (LH);
  3. LH promotes increased testosterone synthesis in the testes.

Mucuna further supports a masculine hormone body-state by acting as a mild inhibitor of prolactin – a protein that can diminish testosterone in excess – while optimizing growth hormone. Mucuna has been shown in research to significantly increase testosterone in men with low sperm count.

About Performance Lab® Sport T-Booster Mucuna Pruriens

Raw velvet bean seeds are 4.2% levodopa. Performance Lab® Sport T-Booster’s Mucuna Pruriens extract is a premium, enhanced-potency form standardized for a minimum of 15% active levodopa. Taken as directed, Performance Lab® Sport T-Booster delivers the levodopa found in 4.3 g of raw velvet bean powder.

Luteolin (from orange fruit extract)
30 mg

Luteolin is a botanical antioxidant that promotes healthy testosterone levels by blocking the aromatase enzyme that converts testosterone into estrogen.

Luteolin’s anti-aromatase activity may be most helpful for men over 30: Aromatase’s testosterone-to-estrogen conversion rate increases as men grow older, potentially contributing to age-related testosterone decline.

About Performance Lab® Sport T-Booster Luteolin

Our luteolin is naturally sourced from premium orange fruit extract; a clean, 100% natural source of testosterone-supportive antioxidant activity.

Who should take Performance Lab® Sport T-Booster?

Performance Lab® Sport T-Booster is designed to be taken by men, only. This formula can help men of all ages who are seeking to safely and naturally raise testosterone levels. Performance Lab® Sport T-Booster may assist with the secondary benefits of a more masculine hormonal status, including muscle development and recovery, weight management, sexual health and virility.

How do I take Performance Lab® Sport T-Booster?

Take 2-4 capsules daily. For best results, take 1-2 capsules with your first meal of the day or before your workout, and then 1-2 capsules with your second meal or after your workout. For best results, Performance Lab® Sport T-Booster should be taken as part of an overall fitness regimen including strength training and cardiovascular exercise. These activities work in conjunction with Performance Lab® Sport T-Booster to raise testosterone levels higher than with supplementing alone.

Why does Performance Lab® Sport T-Booster not include fenugreek?

Fenugreek is a popular herb in testosterone supplements, and it does effectively support healthy testosterone levels. Part of the reason it works is by blocking 5-alpha-reductase that converts testosterone into another hormone called Dihydrotestosterone (DHT), thereby sustaining circulating testosterone levels. The problem: DHT is another important male sex hormone that works together with testosterone. Fenugreek benefits for testosterone are offset by its potential to reduce masculine DHT.

Do I need to “cycle” Performance Lab® Sport T-Booster

For best results, we suggest cycling Performance Lab® Sport T-Booster. In this practice, take Performance Lab® Sport T-Booster for four consecutive weeks, then “cycle off” and do not take T-Booster for two weeks, then “cycle on” and resume taking Performance Lab® Sport T-Booster for four weeks, and so on.

Is Performance Lab® Sport T-Booster safe?

Like all Performance Lab supplements, Performance Lab® Sport T-Booster is designed to be safe for long-term daily use. Performance Lab® Sport T-Booster achieves this by using pure, potent ingredients that are dosed appropriately and in line with clinical research. Free of GMOs, gluten, soy, colorants, preservatives and other additives, Performance Lab® Sport T-Booster is safe and beneficial for long-term use.

Is Performance Lab® Sport T-Booster legal?

Yes. Performance Lab® Sport T-Booster is a safe, natural and legal way to support natural testosterone production. This is important because some testosterone nutrients are not legal in all countries, while others may be banned by professional, amateur and collegiate sports organizations. Performance Lab® Sport T-Booster ingredients are legal all over the world, and supply none of the banned substances that may be present in other testosterone supplements.

Can women take Performance Lab® Sport T-Booster?

This is not advisable. The D-AA-CC in Performance Lab® Sport T-Booster effectively raises testosterone, but may have negative side effects in women. Instead, we recommend that women take Performance Lab® Whole-Food Multi for Women as a starting point for optimal female hormonal health; its essential nutrients are customized for women’s unique.

Is the levodopa in Performance Lab® Sport T-Booster considered to be safe?

The 15% levodopa standardization found in Performance Lab® Sport T-Booster is safe and well-tolerated. But be wary of higher standardizations (up to 98%) as they may carry risks, side effects and safety concerns, especially with long-term use.
