Your best preparation for tomorrow is what you do today. Whether you’re preparing to embark on a high country spot-and-stalk big game hunt or an intense cross country mountain bike ride, physical outdoor activities like these demand that your body be able to handle the extreme conditions required to conquer them. You need vital nutrients to support, sustain and oxygenate the body’s maximum output in order to increase performance in both your mind and muscles. Mtn Ops Yeti™—Monster Pre-Workout Formula may help maintain strength your body needs with normal energy, performance and endurance levels.

One of the major secrets to the success of Yeti™ is the nitric oxide produced. Nitric Oxide helps in dilating the blood vessels and arteries, allowing more blood flow throughout your body and muscles. With Yeti™ we add 1,000 mg per serving of L-Citrulline which acts as a catalyst and prolongs the production of Nitric Oxide. This prolonged production is what aids increased strength, power, and endurance during exercise at home, at the gym, or in the outdoors. Release your body’s full potential with Yeti™ and push your workout past routine into extreme.

    MTN OPS Yeti is a phenomenal pre-workout supplement that doesn’t leave me with bubble-guts, cutting my workout short like some other brand-name pre-workouts.
    The larger containers work great when leaving home or the office and heading straight to the gym.
    Recently I used the MTN OPS Yeti Trail Packs to help keep me awake while my wife was in the hospital, giving birth. I know that’s not really the intention of this product, but it sure gets the job done!

    I’m looking forward to using MTN OPS Yeti Trail Packs on my next Scouting Trip/Hunt/Backpacking Excursion/FTX/Deployment!

    My hubby loved having trail packs when he went to Colorado hunting. Made life easier when all the had to do was drop open a pack and add to water…no measuring.

    Awesome product. I’ve always been skeptical when it comes to preworkouts or any supplements for this matter. YETI not only gives you that huge boost to increase your workouts but it also does NOT give you any crash like 90 percent of supplements on the market do. Please trust me when I say you’ll love YETI.

    I never had really tried any pre workout before I found yeti. And now I can’t see myself using any other options for it. It gives me all the energy and stamina I could use for my workouts and being able to conquer the mountain on those early mornings out in the field. Love the no crash and how it lasts.

    I love to use one of these Yeti packets mid day as I’m starting to get tired and fatigued from either hiking or glassing. It taste great, and gives me the energy and motivation to keep after it! I highly recommend these!!

    These things are awesome! They are so convenient and easy to use. They mix great with a bottle of water and taste great too. I have these in my pack and my truck all hunting season. Take one first thing in the morning and I usually take another in the early afternoon. These are hands down my favorite product. Thanks for such a great product!

    The trail packs are great – used for the first time on my last elk hunt and can not beat the convenience of them. Took 2 ea. Yeti and 2 ea. Ignite per day and ended up using them all! They made all the difference in the world once the hunt got going and we didn’t have time to brew coffee each day – our favorite was to mix Yeti and Ignite together for a “super’ drink!

    The trail packs made travelling this summer with my pre workout a BREEZE!! I couldnt have asked for an easier way to get over the time change lag, and bust out workouts. And the continuous elevation change that made me lethargic… not anymore when I get to carry my pre workout with ease!
