What Is Testosil?
Testosil is a testosterone-boosting supplement for men 25+ who want to increase testosterone for increased muscle mass, energy, and libido. It features 12 ingredients, including 300mg of KSM-66, with clinically-validated ingredients and dosage, and a lifetime guarantee. Each bottle is a 30-day supply.
The maker points to the research on KSM-66 ashwagandha: in an 8-week double-blind, placebo-controlled study, 57 men aged 18–50 took 300 mg twice daily alongside resistance training; testosterone rose by 96.2 ng/dL versus 18.0 ng/dL on placebo (p = 0.004), and cortisol fell by 27.9%. This is research on the ingredient, not a trial of Testosil itself.
