XYO Test by AfterDark is a high-powered, multi-layer testosterone booster built for advanced users looking to elevate natural hormone levels, support libido, improve recovery, and sharpen performance. It brings together a wide range of clinically respected herbal extracts, adaptogens, and micronutrients — all formulated to work synergistically to promote free testosterone, manage estrogen, and help regulate the body’s hormonal environment.
