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 to maintain sustained energy, performance and endurance levels.

One of the major secrets to the success of Yeti™ is its ability to create Nitric Oxide in the body for over 20 hours. 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 may aid to maintain 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.

    I literally just got my green apple yeti in the mail 5 minutes ago. I was super excited to try it that I made a double batch just to have my buddy try it. “ITS HANDS DOWN OUR FAVORITE DRINK EVERRRR” Will be buying plenty more to stay stocked up lol

    My Husband and I ordered this for our pre workout drink, but we also drink it before hiking, and for him, hunting. It gives you that extra boost to push yourself through the workout or the hike. It’s a an overall great energy without the crash! We will definitely continue to order this product. Well done Mtn Ops!

    Great flavor! Awesome way to get to the next level. Started by new year by doing about 1.5 months with no pre workout and after one work out with this realized that I had been missing out. Been using it for about a month now. Seriously awesome. great for getting over the no show results some people have. The bulk is showing!

    I tried the peach flavored Yeti the other day for the first time. I’m pretty picky with pre-workout supplements, but this one is pretty amazing. It gets you pumped with out the crazy tingly feeling and crash like a lot of pre-workouts do, but you still get the same results. I think I’m hooked on this one. Would definitely recommend it to everyone!

    Being a Tennessee boy, there is not a lot of people that believe in the Fit to Hunt lifestyle. Although we spend a lot of time in tree stands, we still have to get there through all kinds of terrain. Also, turkey hunting and other game can get pretty tiresome. After discovering Mtn. Ops through several podcast, ( Cam Hanes, Zac Griffith, The Gritty Bowmen, Etc.,), I have discovered that fitness and hunting go hand in hand. Thank you to Mtn. Ops and these guys for the push and thank you for making such a awesome product! And thank you for being Godly people and doing so much more than just selling products! If you want a push to change your life, Mtn. Ops is the way to go and Yeti will give you that push to get there!

    Wow! This stuff is legit. I’ve used it for about a month and a half and can tell a significant difference in the workouts that I use it and those when I don’t. We race Olympic Tri and Ironman when not hunting and I have tried a fair number of the other products out there. Have used Yeti for both strength training days and for long cardio workouts and it feels like there’s a dude steady shoveling coal into a freight train furnace. Get some.

    Amazing product! Mix this with some Enduro and you can go for hours and feel amazing afterwards. I recommend MTN OPS to anyone doing physically, demanding work or just out having fun or at the gym.

    I’m a UPS driver in Phoenix Arizona, I work out during my lunch hour around 3 pm, I take Mtn Ops YETI 45 minutes before I work out it gives me the extra energy I need to get a great work out and extra energy to finish my route with energy to spare! Great taste easy to mix, this stuff really works and no crash!!!!

    Really gets me going heading into a strenuous hike or hunt. I would only recommend lots of water after using this as you will dehydrate easily if you don’t drink lots of water. I never seem to lack strength or energy after taking this.

    I love the blue raspberry yeti. It tastes delicious and gives me the perfect amount of energy for the gym. I also mix it with enduro for hiking the mountain. I have tried other pre workouts and they give me the shakes and I don’t feel very good afterwards. Not with yeti. Use this product in the gym, hunting, fishing, or any other outdoor activity that requires substantial energy.

    I’ve taken tons of different pre workouts over the years and this is definitely one of the better one! While many on the market just pump you full of false hopes and enough stims to assist you on your way towards premature cardiac issues, MTN Ops has done a great job with giving us a great nitric oxide pump and just enough caffeine take your workout up a notch. I highly recommend this product to anyone and the blue raspberry flavor is my favorite!

    I have been using yeti for the last few months and I won’t workout or go out for a hunt without it. The green apple taste so good I think I have a slight addiction to it! If you’re looking for the run through a wall kind of high this is not your stuff. If your looking for a natural energy with no crash you won’t be disappointed. I love the way it helps me push through the end of my workout as hard as my first few reps. Where I really feel it the most is on long walks of pushing during a hunt. It gives me the energy to push through whatever I’m up against and I have no crash when it wears off! Love it!!!

    Joshua Hurst (verified owner)

    This stuff is so awesome. You may be surprised how small the container is for all 30 servings like I was, but I got the green apple and it taste just like a jolly rancher! Yummy

    Been using Yeti for a few years now and it works. Either before the gym to workout or early morning before long hikes to chase the large muley’s up in the mountains durning hunting season. No crash no jitters just performance

    I ordered the Green Apple Yeti and typically I am pretty sensitive to anything with caffeine so I tempered myself into this slowly with 1/4 recommended dosage and worked my way into the full dosage with zero issues. The “pick me up” ramps up slowly and delivers when it’s needed. Utilizing Yeti to get through heavy squats, deadlifts, and demanding metabolic conditioning workouts allows me to push further and harder. The taste of the green apple is subtle, not too sweet, and no awful after-taste. My only issue with the product is mine came rock-hard like there was moisture in it from packaging so I have to chip away at it with a butter knife and rolling-pin to get at it. I do love this product and I will purchase it again even if I have to use an ice pick and a mallet.

    Best pre-workout I have ever had. Kicks in immediately and last for a long time without giving you a jittery feeling.

    Love this product! It definitely keeps me going without the mid morning crash. I actually forgot to take it this morning before my workout and I felt the effects by 10 am. I was sluggish and sleepy and felt like I couldn’t keep up. I would recommend this product to anyone who wants to avoid those post workout crashes.

    I never took supplements prior to this year, even when I was power lifting and playing sports. I got introduced to this and I am hooked! I take Yeti before my workouts and it helps improve my endurance so I can do a full cardio routine after I lift. No jitters or overly weird tingling. I take it almost every day and I love it!

    My husband has been using this product for quite some time now. I began working out about a year ago and first started taking this about 4 months ago. The difference is amazing. It really gives you that extra boost to give it your all during a workout. Best part is no crash later! I will continue to take this product along with my magnum protein!

  34. 5 out of 5

    Scotty (verified owner)

    Best preworkout ever! Gives you a boost without a scary jittery gross feeling. I have the green apple, blue raspberry, peach, and watermelon and none of them have a fake/ nasty aftertaste flavor that literally every other preworkout I’ve tried, has. All of them mix extremely well. Couldn’t be happier with the Yeti. Also, mixing green apple and watermelon 50/50 is super good definitely a must try!

    I am a FedEx truck driver, I drive 18 wheelers for a living and get up at 4 in the morning everyday. I pull 3 to 4000 lbs cans off of the plane and put them on my truck. So when I need the extra strength or a bit of pump I take yeti! I have got watermelon flavor and strawberries and bananas and those are great! I have also tried green apple and blueberry but those were too sour for me in the morning. This is a great product and starts my morning everyday!

    Joe (verified owner)

    I decided to give the Yeti a try because I couldn’t get through my full workout. I typically run 2-3 miles at the end of my wor out and I found myself stopping at mile 1. This stuff gets me through my workout and keeps me energized afterwards. All with no crash, no jitters, and no regrets!

    Good stuff. I use this before any strength training or cardio workout and it definitely helps me get through them. Also use it during the day while hunting, especially after lunch when I tend to get a bit lazy.

    so, I was venturing out beyond your typical pre-workout from walmart when a friend suggested mtn-ops. Between that, and their company values I thought I would give a try. got both peach and green apple, they taste great!! at first, to be honest, I didn’t get the big kick I need. but every person is different. I found I really like this particular drink when Im committing to a longer workout or sport. for example running, cycling or mountain biking. I might mix up something else for lifting weights for an hour, but I have come to really like having the alternative the mtn-ops gives me when I need it to not hit me too hard up front, maintain longer, and not crash at the end. those of you who mix workouts with actual outdoor activities will know what I mean. take some c-4 and plan to go hiking or climbing and you’ll have a hard time getting back, not with the mtn-ops. i plan to keep using it! and have suggested to many!

    After using other pre-workouts in the past, I was thrilled to have discovered Yeti. While many others have poorly flavored dust that fills the room with a terrible scent, Yeti is just like drinking a normal sports drink with the added pump. I’m wrapping up green apple soon, psyched to try the other flavors!

    Love this product! The variations in flavors , which I haven’t found one I don’t like, keep me on track and never bored with my pre workout. It mixes so well and there is no grit or funky aftertaste to complain about. Homerun!

    Yeti is the best pre workout I have had! It has such a clean and smooth energy to it that I am able to utilize it in many different arenas. It works great at the gym from powerlifting, Olympic lifting, and metabolic conditioning as well as climbing the mountain and packing out an elk! I will be a yeti fan from here on out! #YETIMODE

    The strawberry banana is my go to for evening exams, trust me as a college student this is far better than energy drinks and you won’t crash nearly as hard after.

    I’ve tried most the competing products and hands down YETI is my favorite. It isn’t gritty at ALL which is my biggest problem with most pre workouts, even if you mix it with small amounts of water before a workout. It tastes great (I don’t like sweet pre workout so the green apple is great). It gives great energy without peaks and lows. I use it before the gym and in the field and absolutely love it in both places.

    I had never used a PreWorkout before trying this. I am IN LOVE with the green apple flavor. Its not to sweet but it gets the job done. I keep this one in my car now for when I forget to pack my powders. I do have to say I will continue to keep buying it.

    Ok, been on this for around a month. You wanna know what crack is like without having to sell knock off watches to afford your habit? TRY THIS STUFF! This will give you a bump like nothing else. If the Yeti truly feels like this, he could be hairless because this stuff gets your blood pumping! No wonder the Yeti is HUGE, dude is on a straight pump for daaaayyyyyssss! Seriously though, this stuff is awesome and actually works, gives a great boost to get through long workouts and get a sweet pump!

    Worked perfectly when needed. I bought this initially for workout purposes for upcoming 1st Elk hunt. I used it 2 months prior to hunt and it delivered what was promised. I had 2 scoops left going into the elk hunt i used the first scoop after my friend that was with me on the elk hunt to haul out the second load of deboned elk meat via backpacks. We have never trained for this type of load on our backs but it was like it was nothing after drinking the yeti. So 2 days later i got myself a bull elk. Again on the second trip in to get the Elk we were burned out on the first and needed the push. So last scoop it was for the remaining haul out of the meat. And again it performed great setting us up for the last and hardest haul out. Thanks Mountain Ops for everything.

    After a ton of research for different pre-workouts, I decided to give the blue raspberry Yeti a try. Holy smokes, I was so impressed! I noticed a big difference especially in my kickboxing classes. I’d normally feel myself burning out around the 3rd bag round but since using Yeti, I still have energy after I leave class and don’t feel the need to go home and nap anymore haha 🙂

    As a gym rat for the last 12 years who has tried tons of pre workouts, I’m giving yeti 4 stars for only one reason, which is that it’s probably a little higher in stimulant than the average person needs. If you’re looking to get jacked up for a workout, it’s going to fit your needs. If you’re looking to drink it and go hunt, it may make you feel a little icky if you haven’t eaten much. I personally find it best for intense muscle building workouts. There is no crash off yeti, which is nice as well.

    Best tasting and best working pre workout I’ve ever used! No jitters, just focus and energy. Additionally, it has the other essential micronutrients needed for an effective workout and recovery. If you are sensitive to caffeine, or haven’t tried a pre work out before, take half a scoop and don’t take it after 5pm. Like any other supplements, if you over use this your body will adapt and you will no receive the benefits from what this product is meant to do. I recommend using 2-3 times a week and prior to an more demanding workout.

    Normally it’s hard to find a good pre that doesn’t make me sick, but Yeti is that pre. I use Green Apple, Peach, and Blue Raspberry. Flavors are great. Only drawback is low beta alanine so I don’t get the buzz I love 😂

    Consistently a great pump and energy to get through some of my toughest workouts.

    The green apple mixed in with Mountain Ops BCAA’s in my shaker bottle with water – pre/during my workout really makes a difference in the quality of workout that I get! Helps me have the drive, focus and energy to get it in every time. Even if I’m dragging and could easily skip, I start drinking some of the Yeti and it helps me get back in the game. You won’t regret trying Yeti!

    YETI is a powerful and very tasty pre workout. I have to use only a half serving because I am a hyper and easily charged person, but this gets me going without fail. I love the flavors and I never get jittery or anxious like I have with other products.

    I’ve never really used many preworkouts through my training history. The few I have used I didnt like the way they made me feel. But this stuff is awesome. Gives me great energy without any jitters, and helps push me through an intense workout!! Also, it taste great

    My girlfriend and I ordered this to try it out. Gave me the right amount of boost and energy, but yet not too intense for her! Mixes great and taste amazing, a must try!

    Best preworkout I’ve had, good energy and pump with no crash. I usually double scoop me preworkout but with this 1 is enough. Tastes great too!

    This is the product that started my addiction with mtn ops! This is coming from a guy who does not like to work out but with yeti it gives me that extra boost to get through it and after months of getting into the gym I actually started seeing changes and enjoy exercising now. Thanks MTN OPS!

    Having tried other pre workouts and it made me all jittery. I didn’t like that feeling. When I took Yeti i felt the energy but didn’t have that jittery feeling. This product mixes extremely well and tastes great!!! I switch between what flavors I order because they all taste great! Yeti will definitely help you get the gains you want so you will be able to handle any situation when you are in the field!

    Incredible flavor!!! By far the best tasting pre workout I’ve ever tasted, Not only does it taste good but there’s no crash. I’ve taken this while doing homework, choirs around the house and even at work and got the energy I needed and getting run out of energy after a few hours. The only reason why I’m giving this 4 stars is because it’s not strong enough in my opinion. I usually sip on YETI throughout my workout and sometimes I’ll drink it all before my workout and I don’t notice a big increase in energy. Usually I’ll take 2 scoops with 16 oz of water and it’s more than enough energy for me.

    I have used Yeti Pre-workout for about a year lifting. I definitely helps to get in long more intense workouts. One of the huge benefits is also the no crash. My shift at the Fire Station all use Yeti while working out on duty. As we may get called at any time of the day, we cant afford to have the crash that many other supplements have. A Platoon swears by Yeti. My favorite flavor is Peach.

    I absolutely love this pre workout I’ve tried so many others on the market and have not been impressed this is a healthy option that will absolutely do the job!

    Hands down, best preworkout drink I’ve ever had. I’ve only bought the green apple flavor so I cant say how the others taste. Definitely allows you to feel good at the gym with a nice extra boost. No crash feeling after words…if anything, I feel better.

    I used to double scoop C4 for my pre workout routine, found MTN OPS yeti and 1 scoop is the perfect amount. Wait 15-20 minutes and hang on! Great stuff Great company!!

    Every single flavor in Yeti is better than on any other Nutrition Formula! Love all of them! For warning, Tigers Blood is a coconut flavor for those of you who do not like coconut flavor. The Watermelon flavor is THE BEST Watermelon flavor I have ever tasted in my life! Awesome!!!!

    I have been using YETI for over two years now, and have been extremely happy with my performance in the gym and in the field. I have tried every flavor and like them all. ‘Hours of sustained energy’ is exactly what I experience. The jittery feeling is non-existent whether I grab it on the way out the door for a fasted workout, or take the time to fuel my body beforehand. I love this stuff!

    This is my absolute favorite product available! Unlike other pre-workouts, I never get the crazy itchy, jittery feeling that comes with some. I do however feel a noticeable difference in my energy level about half way through a workout. I really believe using this has allowed me to make a big increase in the quality of my workouts and therefore feel better than ever.

    I absolutely love this product. The first time I used it I wasn’t actually planning on working out but after about 20 minutes I just couldn’t help but want to work out. I start my mornings with a Yeti, then I study and read for 30 minutes, and then I am ready to get my workout on! One of my favs from MTN OPS!

    Best Pre-Workout ever, Fast energy doesn’t give you the shakes or the itches like most. I’ve used Peach and Tigers Blood and love the taste! Highly Recommend!

    Yeti has been my GO TO pre workout for over 3 years. It gives me sustainable energy in the gym, no jitters and no crash. Its everything you would want in a pre-workout!

    KICK-ASS pre workout! It says “monster pre-workout” for a reason, solid pumps and love the combo of goodies to keep me going during my workout. Watermelon rocks and I’m not a watermelon fan at all.

    I love using this product before every workout. There are days its just hard to get going for a workout but by taking Yeti 30min before I am pumped up and ready to hit the gym. I absolutely love the flavors, peach is my go to flavor!

    Great preworkout. I have a fairly long drive to the gym every morning, and I drink this during that drive. By the time I get there, I’m revved up and ready to go with intense concentration and clean energy. I’ve had the Blue Raspberry and Strawberry Banana so far and they taste great. Not too sweet. Give it a try. You won’t be disappointed.

    Another incredible supliment from a Company that Rocks! Honestly this got me through leg day when I litterarly did not want to do anything physical or mental that day but with the help of Yeti I got that spark and push that I needed to help me crush that circuit! This is my go to before any workout. I have been using it for about a month after switching from another company that made me crash hard when it wore off and I am very impressed with the flavor, no crash but sustainability of energy throughout my workout! It’s not a smash you in the face energy it emerges quietly and then boom your ready to crush your routine! Then slowly fades away later. Love the stuff!!!

    This is by far the best pre workout I’ve tried, and I’ve tried A LOT over the years. It has just enough UMPH to give you the most workouts, without putting you over the edge a other preworkouts do. Heavy lifting to cardio, this stuff is legit!
