Our Verdict
For men over 40 dealing with stress, sleep, and the cortisol-driven side of testosterone decline, Testosil is the better choice - the 300mg KSM-66 Ashwagandha at full clinical dose, lifetime guarantee, and lower price tip the scales. Prime Male is excellent if you want boron and Mucuna Pruriens specifically and your testosterone issues are more libido-driven than stress-driven.
