Formulation Notes

Optimum-Strength Testosterone Up Pro-GrowtH was designed to enhance male physiology by delivering a powerful testosterone boost along with targeted extracts and nutrients to support post-work out recovery and key muscle repair and growth mechanisms. Testosterone boost Featuring PrimaVie Shilajit Extract. Traditional Ayurvedic texts describe Shilajit as a Rasayana, or rejuvenator that has long been used to promote longevity and resilience. Modern research shows that PrimaVie Shilajit significantly boosts free and total testosterone in healthy men. Muscle adaptation & post work-out recovery support KSM-66 Ashwagandha + PrimaVie Shilajit Extract both deliver powerful performance boosts by supporting muscle adaptations to optimize intra-workout performance and enhance post work-out recovery for superior muscle gains. This formula also delivers omega-3 dense fish oil, and Vitamin D3 to promote a healthy inflammatory response - a critical component to muscle repair and growth. Aminos + AstraGin This formula features a select combination of amino acids that have been a focus in longevity research and are thought to support key processes in the body. AstraGin is a proprietary extract that enhances absorption of amino acids for optimized nutritional benefits. For desired results, use in conjunction with regular resistance training.
