MTN OPSMTN OPS Enduro Nitric Oxide Supplement & Stim-Free Pre Workout - 30 Servings - with Magnesium Citrate, Beet Root Powder, Niacinamide, L Arginine & L Citrulline - Tiger's Blood Flavor

Exactly as advertised. Exactly what I needed.

MTN OPS Enduro appears to work. When starting any kind of supplement, it is difficult to determine whether certain gains are attributable to your continued training or the supplement.My cardiologist recommends his patients take an L-Arginine and L=Citrulline supplement because of the proven increase in Nitric Oxide. Increased Nitric Oxide has shown to be cardio-protective. Nitric Oxide also has the benefit of aiding in increasing your body's ability to properly hydrate and recover. For an endurance athlete, both the heart benefits and the training benefits are a plus.On days that I miss taking Enduro, I can feel a noticeable decrease - albeit small - in my endurance. Because I feel like there is some performance gain, along with the heart healthy nature of Enduro, I would recommend the supplement. Yes, the performance impact may, at least on the short term, be a placebo effect. I still feel that Enduro is a wise investment.Pros:Tastes goodEasy to mixHeart HealthyNoticeable gainsCons:A bit expensive to some lesser known brands.

I had tried it from a friend and then ordered my own and was just as satisfied

I need to start out by saying that I love the mountain OPS company. I really haven't been disappointed by anything I've ever tried from them. This nitric oxide booster is no different.One serving of the booster produced results in me that were exactly what I expected. I had a better pump, and overall better blood flow. Away from the workout room, the blood flow still worked really well... all over if you get my drift.It tastes different from any supplement I've ever had period it reminds me a lot of the purple mouthwash flavor. It doesn't taste bad, but every time I have a glass it still surprises me.Great product.

This product does not work, I am not sure what all these other reviewers are saying, it did not provide any energy, if anything it took away my energy

When I saw the flavor name “Rocky Mountain Rickey”, I was definitely intrigued. I couldn’t make out what the fruit was on the label and there were no other descriptions, so I took a chance. Upon closer inspection of the delivered product, the fruits on the label are grapes and a lime. So.. that’s the flavor: Grape/Lime.It’s a pretty purple powder in the container (with an oddly large oxygen absorber with the powder). The color when mixed is also a pretty light purple. My first sip and my eyes went large. The flavor is a spot. on. Dimetapp medicine duplicate. Even the down to the artificial sweet aftertaste! I IMMEDIATELY went to every person in my family and insisted they had to taste this. I didn’t give them any hints at all but every single person independently identified the taste match. One of my sons even asked if I was dosing him with medicine in disguise.I will not be finishing this one, but one of my sons (who LOVES the flavor) will gladly continue using the Rocky Mountain Rickey. I have no idea if it matches the hydration advertised, because taste rules in our house.

I’ve been using the MTN OPS Enduro Nitric Oxide Supplement for a few weeks now, and overall, it works well for what I need. The flavor isn't bad tasting, which good. One thing I like is that it doesn’t give that tingling feeling in the skin that other pre-workouts sometimes do. While it doesn’t give me extra strength, it definitely helps with stamina, allowing me to go a bit longer during my workouts. I’d say it’s an average energy drink. It’s not super potent, but it gives me a steady boost. It’s easy for a normal person to use without feeling overwhelmed by the effects. Even though it says it has no sugar, it still tastes sweet, which is nice. The recommended dose is one scoop twice a day, but I’ve been taking just one scoop a day, and that’s enough to give me the focus and energy I need to push through my day. Overall, it’s been working well for me.

I prefer the taste of other supplements. This one lacks much flavor but does have a chemical aftertaste. I could tell no difference between working out with or without this supplement.
