NITRAFLEX Sport, Blue Raspberry, 10.9 oz (20 Servings)

I take a half dose and it still works in the afternoon after work and it definitely helps me with putting a pep in my step to get my work out going!

The first time I used this I mixed it in with my normal shaker and the full 17 ounces. It was a little weak. The next time I ratcheted down the water to more of what they stated and it tasted much better. This gives a good boost for working out and I like it that it mixes in really well.

this is a very strong pre workout that has a similar amount of caffeine to a cup of coffee. the beta alanine makes me very itchy, the first time i took it my ears and eyeballs itched. this pre-workout is effective and very sweet despite all the salt which i feel gives a more pronounced pump. this product only has twenty servings which i feel isn't enough for the price.

This is an ok pre-workout. It doesn't give me the same amount of boast of energy as other pre-workouts I have taken. This may be good for those that are caffeine sensitive. The taste is ok but not the best tasting as well.

Flavor is good enough for a pre-workout, enough caffeine to get you moving but not so much I got jittery. No tingling or other side effects. Just good energizing pre-workout. I don't usually use caffeinated pre-workout, but I'm keeping this as my go-to for when I need that boost.

I weight train three (3) days/week. Between those days, I fit in Pilates, swim, bike. I train for both strength and endurance; for me these are complementary goals and they help each other.For strength training, you want to hit a point of progressive overload. However leg day I sometimes run out of fuel before I run out of strength; this is NOT for lack of calories. I have tried pre-workout supplements for strength and have less “crash” although it still happens (again leg days). I tried some pre-workout supplements for endurance, but still some weeks simply not pushing through. Which is odd, because often the next workout of the same will power through like nothing? This is the opportunity I am seeking to leverage with Nitra Flex Sport; less workout crash on leg day.This contains caffeine; typically what you might get in a couple cups of coffee in a full scoop. Based on this, I will only include it in morning routines. Also, if you are using pre-workout supplement, you may already be using Creatine and caffeine can impact your Creatine absorption.For now, I just got this and really need some time before I can give results. Not my favorite flavor (very individual, no stars deducted), doesn't completely dissolve (typical, drink the powder clumps...). After a single workout, I do note that both my squat and deadlift are at new highs, but again that is correlation of a single data point. Fingers crossed; I certainly have a need I hope this will help with.Double sealed (under the lid, shrink-wrap lid), made in USA, GMP. Have some confidence in the quality of the product itself.

The flavor of this fruit punch isn’t great, can’t quite put my finger on it. Also, I did not notice any difference in my energy level before my workout. Kind of a waste, disappointing.

I have found that pre workout has been getting more and more expensive these days, so ~1.25 for a serving seemed like a good deal. This pre-workout is definitely a value buy to that end. I have had pre that would give me more energy or a better pump, but this stuff is definitely good enough for most days. I wouldn't take it if I were trying to hit a PR, but for most days it will be great. Taste is good enough, effecti is good enough, and for the money, you can't beat it.
