"My testosterone went from 400 to 859” ng/dL" - Adam
Testosterone With Age
Testosterone levels decline with age due to reduced testicular function and hormonal regulation changes.
Why You Want High Testosterone...
Energy
Having more testosterone can improve energy by enhancing red blood cell production, which boosts oxygen delivery to muscles and tissues, leading to increased stamina and vitality.
Muscle
Having more testosterone promotes muscle gains by increasing protein synthesis, which supports muscle growth and repair after exercise.
libido
Having more testosterone boosts libido by stimulating sexual desire and supporting sexual function through its influence on brain regions related to arousal and motivation.
Drive
Having more testosterone can enhance ambition by increasing motivation, confidence, and drive through its effects on brain regions involved in goal-setting and reward processing.
What's In It?
Tongkat Ali (500mg)
Tongkat Ali, a traditional herbal supplement, has been shown in studies to boost testosterone levels, particularly in men with low baseline levels or under stress. Scientific evidence supporting this comes from 9 human clinical trials, such as a 2012 study, which found that 90% of participants experienced increased testosterone after one month of supplementation.
PrimaVie Purified Shilajit (250mg)
Shilajit PrimaVie, a purified form of the mineral-rich substance shilajit, has been shown to enhance testosterone levels and improve energy levels. Multiple clinical studies indicated that supplementation with Shilajit significantly increased total andd free testosterone levels in healthy men after 90 days of use.
Fadogia (200mg)
Fadogia agrestis is a plant native to West Africa, traditionally used for enhancing vitality and sexual health. It is believed to support testosterone levels and improve physical performance, often used as a natural supplement for boosting testosteronee and libido.

How It Works
After digestion, Tongkat Ali and Cistanche stimulate the pituitary gland to release more luteinizing hormone and follicle-stimulating hormone into the bloodstream.
The Leydig cells in the testicles detect these hormones as a biological signal to increase testosterone and sperm production.
Increased testosterone levels help to build muscle, increase libido, boost erectile function, decrease stress and enhance your mood.
