28 Days Later Will Change You

28 Days Later has been readmitted to the Asylum.  The Mad Chemist has formulated one of the most intense test boosters known to mankind. Build the ultimate muscular powerhouse, 28 Days Later. 

  • INCREASE TESTOSTERONE LEVELS.  With our patented ingredient Blamus, 28 Days Later increases your body's free testosterone levels.  With increased test levels, you’ll be able to lift longer and be stronger every gym session. 
  • BUILD LEAN MUSCLE MASS.  Not only is 28 Days formulated to increase test levels, but we also formulated 28 Days to increase your body’s ability to build lean muscle mass.
  • ALL NATURAL INGREDIENTS. To give you additional benefits, we added these natural ingredients: Velvet Bean extract, which has been shown to boost testosterone, treat male infertility, and protect the body against disease. GABA (Gamma-Aminobutyric Acid) has been shown to improve lean muscle growth, burn body fat, improve your mood and reduce anxiety and Valerian root, which is commonly used to treat stress, anxiety, and sleep disorders. 

28 Days Later features the Asylum's trademarked ingredients Blamus, known to increase free testosterone levels and boost athletic performance, and AMPitest that aids in boosting your immune system.  28 Days Later comes with 30 servings in capsule form.
