About XYVantage Boost
XYVantage Boost centres on TestFactor, an ingredient studied in human clinical trials for supporting healthy testosterone levels in men – not just a botanical thrown in on general reputation. Supporting natural testosterone production this way is aimed at strength, consistent performance, and sustained energy, rather than a short-term spike.
KSM-66 Ashwagandha is included alongside TestFactor to further support natural testosterone levels, encouraging muscle development, endurance, and a healthier body composition over time. Rounding it out is a proprietary blend of complementary botanical extracts working together to support overall vitality, rather than relying on any single ingredient alone.
Testosterone Support
TestFactor, KSM-66 Ashwagandha, fenugreek, and longjack work together to support natural testosterone and hormonal balance.
Muscle Strength
TestFactor, KSM-66, fenugreek, cayenne pepper, and longjack support muscle strength and endurance through workouts.
Energy & Recovery
KSM-66 Ashwagandha supports recovery from exercise-induced fatigue, while Mucuna pruriens and theobromine support energy, focus, and consistent performance.
Mood & Motivation
Healthy testosterone levels, supported by TestFactor, fenugreek, and longjack, may support libido and motivation. Mucuna pruriens further supports drive and mood.
Overall Vitality
Pomegranate supports cellular health, cayenne pepper supports metabolism and energy, and black pepper extract supports nutrient absorption so the other ingredients are put to better use.
