grains of paradise (6-paradol), aXivite® phenylcapsaicin and clinically tested boron. AlphaTest® Thermo XTR enhances testosterone production while energizing your training, for jaw-dropping results!▲

  • KSM-66 Ashwagandha: A powerful adaptogen that has been shown in a clinical study to support strength and muscle size, as well as promote total testosterone.▲
  • Enfinity: Breakthrough clean, safe and effective metabolite of caffeine. Delivers hardcore thermogenesis, clean energy and focus.▲
  • Grains of Paradise: The seeds of Aframomum melegueta has been used traditionally and supplies the pungent compound 6-paradol.
  • Axivite: Feel the heat from phenylcapsaicin, a derivative of capsaicin, which is an active component of chili peppers.

1In an 8-week study, test subjects taking a key ingredient found inAlphaTest® Thermo XTR
increased their total testosterone levels 4X more than those who took a placebo (96.19 vs. 18 ng/dL)!▲
