Label Claims

  • Builds muscle.
  • Raises pH levels for more muscular endurance.
  • Increases the rate at which the body produces energy while training and/or while under stress.

Here’s what I’ve found

  • First, I was impressed with Opus’s ingredients. Lots of good stuff.
  • Mixes well in my shaker cup; no grit.
  • Some pre workouts taste gross, but I love Blue Yaspberry’s tangy sweet flavor. I haven’t tried Cellular Punch yet.
  • I take 1 scoop early in the morning on an empty stomach and it doesn’t bother my gut. I have taken others before that bother my stomach.
  • It’s definitely helping with my energy levels during training.
  • I find I am stronger and able to squeak out a couple of extra reps.
  • Unlike other pre workouts I have tried in the past, this one doesn’t give me jitters.
  • No tingles.
  • Helps keep my hydrated during my workout.
Beastly Tips

I drink Opus on the way to the gym and HI5 intra workout.


Overall I give this product a 5/5.

This product does just what it says and then some. I absolutely love Opus! I feel stronger during and after my training session. Opus has fast become a permanent fixture in my pre workout stash.

I would definitely recommend Opus to anyone looking to take their training to the next level. But I would also highly encourage you to give it a try if you have a sensitive gut, or gastrointestinal issues. I personally feel you’ll have success with this product.
