King Test is the most effectively dosed testosterone booster on the market. Backed up with a fully disclosed non-proprietary blend formula.




    • Increased Libido

 


    • Increased Testosterone

 


    • Increased Energy & Stamina



King Test is designed to increase natural testosterone and free testosterone levels, greatly increase libido (sex drive) as well as increased energy and stamina.

 

Whether you are new to working out or a seasoned athlete it is common knowledge that testosterone is one of the keys to building muscle, losing fat, a healthy sex drive and many other life improving factors. Sadly, as quickly as our natural testosterone levels increase and peak, they begin to fall until eventually they are almost not even there. Many of you are probably thinking what makes King Test different from every other testosterone boosting supplement on the market? King Test has the highest quality ingredients at the most optimum dosage rather than the watered down versions in many. We challenge you to find another testosterone booster that makes you feel as good and work as well as King Test does.

 

King Test will promote natural testosterone for those with already lowered testosterone but also work great for men in their 20’s who have not had their levels plummet yet. It can also be used during PCT to help bring back up Testosterone levels quickly.

 

 

 

What’s in KING TEST?

Vitamin D3 (2500IU) – In studies men that supplemented with Vitamin D caused significant increases in testosterone compared to placebo. This trend also occurred with free testosterone and bio available testosterone.


D-Aspartic Acid (3g) – DAA increases testosterone by the up regulation of mRNA. During a study on 23 healthy men, 20 of the 23 of them increased testosterone levels by an average of 42%. After stopping the study their testosterone levels remained 22% higher. Another study showed an increases of testosterone by 20%.


Maca Root Extract (1.5g) – Whilst Maca does not effect testosterone it is highly effective at increasing sex drive levels, especially in men with lower testosterone. It was reported (self-report as part of a study) that Maca increased sex drive between 24.4% and 40%.


ProLensis (1g) – ProLensis is a multi-faceted compound in all of the ways it exerts its positive effects on the hormonal balance of the body. Pro Lensis increases GnRH-LH signally as well as increasing cholesterol in the testes, both of which are extremely important for testosterone synthesis.


GnRH (Gonadotropin-Releasing Hormone) is released from the brain which then in turn stimulates the release of Luteinizing Hormone (LH) from the Pitutary. LH directly stimulates the Leydig Cells in the testes to release testosterone. Evidence has shown that ProLensis can stimulate LH by 169%.


ProLensis also elevates levels of testicular cholesterol. Which is effectively the raw material for creating testosterone in the testes. If cholesterol levels are not elevated in the testes then testosterone cannot be increased. Research has shown that Prolensis can increase testosterone by 347%.


ProLensis demonstrated in studies a estrogen reduction of as much as 35% as well as not increasing Prolactin (serum) levels. ProLensis has also been shown to work as an aphrodisiac and when given to mammals has shown siginificant increase in frequencies to mount, intromission, ejaculation and ejaculatory latency due to the increase in acid phosphatase (ACPT).


KSM-66 (1g) – KSM-66 is the highest quality, most proven and best bioavailability extract of Ashwagandha. In a clinical study KSM-66 increased testosterone by 17%, semen volume by 53% and sperm concentration by 167%, sperm mobility by 57% and luteinizing hormone by 34%.


Black Pepper Extract (10mg) – Black Pepper Extract helps your body absorb the other ingredients at optimum levels.

FAQ


Open tab




How should King Test be taken?


10 capsules per day. 5 in the morning and 5 in the evening. We know that 10 capsules a day sounds like a task but in order to make the perfect testosterone boosting supplement the dosages had to be this high and sadly you cant make these ingredients taste good.


Do you have to cycle King Test?


As King Test is a natural product it can be taken year round with no issues.


Can you stack King Test with Regenerate?


Absolutely!
