    • Game changer!

      First week using Endoflow and all I can say is… WOW. For the last month+ I’ve been struggling to get my legs back post my “A race” mid July. Legit, first day using Endoflow my legs felt considerably better, then Wednesday dropped a threshold run that’s not far off pace from peak. Crazy excited to continue use and see what’s next!

    • Low Key 🔑 A secret weapon

      I view this as a way to amplify my high intensity work to achieve paces or power that would be otherwise more difficult without endoflow

      Do you find most supplements thoroughly confusing? Do you often wonder what half the ingredients are and if they are actually doing anything to benefit your health and fitness? Do you sometimes feel as if your hard earned money is being spent on overpriced products that are mostly hype and little help?

      I created Simply Good Supplements to help you separate fact from fiction and make natural products that are simple, clean, effective, and supported by the latest scientific evidence.
