Like Milos Sarcev said, intra workout nutrition is extremely important. Opus is epic in this area.*

Absolutely love this product. Although I already take preworkout. , this gives my workout a huge kick and I go on overdrive!! Be careful though and start with 1 scoop if you are already taking a strong preworkout. However, this may be enough on its own. Nevertheless, YOU WILL feel the difference.*

This dissolves well and does the job. For sensitive palates the flavor can be intense but if you're like me and taste doesn't matter just function it's a good choice.*

The twister pop flavour is delicious. I like the fact that is is stimulant-free so I can use it during my late night workouts.*

This is normal intra- workout, do not expect anything special, you need 2-3 tablespoons so that it starts to work.*

I have tried many intra workout products, but this is hands down my favorite. When I'm working out this is my go to drink. And it gives a good boost of energy for times when I dont do any stimulants.*

I am taking a stim break after my show and so I decided to try out Opus for my pre workout. Its done a great job of giving a solid pump and helps me fight fatigue during the workout. Tastes pretty good but you definitely can feel the beta alanine as it hits your tongue.*

Opus is truly an amazing intra-workout. It gives you tons of energy with having any atoms if your body is sensitive to that. Both flavors are great!!!!*
