    Excellent 4.8 / 5

    • Great Product

      Since taking Halo I no longer experience aches and pains. Stoped taking it for a month and my lower back pain came back. Definitely would recommend especially when training hard.

    • Real Performance Results!

      I have used this off an on over the last 11 years. I really think it has helped me push through limits and do things I wouldn't have without it. If I am training I am including this in my training plan to get the results I want.

      Eric

    • Support and confidence for optimal health

      When my body needs as much support as possible to perform at a high level day to day, I can rely on this supplement to cover each of my needs. Before I tried the MultiV Pro, I have never found the right combination of vitamins and micronutrients in one product. Instead of taking a handful of pills twice a day, I have one product that gives me the confidence that I am giving my body the best chance at recovery and optimal health.

    • HALO clears out inflammation

      HALO is my new recovery weapon. I use it after all my hard workouts to clear out inflammation. HALO absolutely destroys DOMS and gets me ready for the next ride. Essential to recovery on multi day cycling trips where you are riding day in and day out.

    • It works!

      I have found over the years that Optegyn helps me recover faster and train at higher volume which translates into better performance in competition.

    • Accelerated Recovery

      Easy to take. No taste whatsoever. Seemed to help with a recent joint injury, and has reduced knee and ankle injury for less downtime and more training.
