About Each Supplement

Tongkat Ali

Tongkat Ali is a 100% natural plant extract.

With a focus on high-quality production, this supplement is rich in eurycomanone, a key component known for its effectiveness. Ensuring purity and potency, every batch is rigorously third-party tested, not only for its eurycomanone content but also for safety against heavy metals and contaminants, distinguishing it from many other products in the market.

Fadogia Agrestis

Fadogia agrestis is a shrub found in Africa, notably in Nigeria. The stems are used to make supplements. It has traditionally been used as an aphrodisiac and and energy booster.

Turkesterone

Turkesterone is a compound found in a plant called Ajuga turkestanica. More specifically, turkesterone is a phytoecdysteroid: a plant compound with a chemical structure similar to steroid hormones produced by arthropods.

Vitamin D3 & K2

Vitamin D3, also known as cholecalciferol, is one of the two main forms of vitamin D. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal muscle function. We have combined it in one tablet with Vitamin K2.

ZMA

ZMA contains 3 ingredients

  • Zinc
  • Magnesium
  • Vitamin B6

Zinc contributes to the maintenance of normal testosterone levels in the blood and to the protection of cells from oxidative stress.

OUR SUPPLEMENTS ARE 3RD-PARTY TESTED

To prove the quality of our supplements, we get them tested by 3rd-party laboratories. Most supplement companies do not get the quality of their supplements verified by 3rd-parties. This means their customers have to blindly trust claims of high quality. We’re different. Our supplements are 3rd-party tested for:

  • Identity, confirming our supplements are authentic
  • Potency, confirming our supplements contain the compounds responsible for their effects
  • Adulterants, confirming our supplements are free of adulterants commonly added to sports supplements to artificially enhance their effects
  • Heavy metals, confirming our supplements are among the lowest in heavy metals on the market
