Today I will be talking about a brand new pre-workout product called OPUS released by Magnum Nutraceuticals. This product is not being sold anywhere in stores or online yet (**Update: It is now online at BodyBuilding.com!) and I am one of the lucky few to test it out. I will try to be as helpful and informative as I can but if I have missed anything or if you have any comments please do so at the bottom of the page.
Magnum Nutraceutical’s OPUS Rating
Overall, I give OPUS a 9.5/10.
Completely caught me off guard with the energy a stim-free formula can provide while having an extremely solid performance enhancing formula. My favourite stim free formula I have taken to date.

“So what is OPUS?”
OPUS is a completely stimulant free, powdered pre-workout product designed to enhance performance, energy, pH balance, blood flow and hydration. Its directions are to take it only 5-15 minutes prior to training, which is a bold statement considering it is a stimulant free formula but they put those directions there for a reason, the product delivered. As you can see from where the majority of my reviews come from, my favourite thing to try out and review are pre-workouts, and when you look at how many I’ve taken and the doses I take them in you could say I have a pretty high tolerance for caffeine which made me overall the perfect candidate to critically review a stim-free formula.
But I really can’t.
I genuinely felt a solid energy rush within 10 minutes of consuming this product that I was not expecting. I got all the same feelings you get from a stimmed pre-workout such as the eyes start to widen and don’t feel as heavy, your focus starts dialling in, energy levels climb up and you feel like you want to go lift something heavy. From an energy standpoint, this product delivered more stim-free energy than Omega Sports Ultima, which is saying a lot.
Aside from the stim-free energy the formula itself is that of what you would want in your pre-workout nutrition. All larger dosed ingredients are instantized for quick mix ability. As you can see below, I received the “Cellular Punch” flavour and it mixed up with no effort and had no ruminants on the bottom:
With a completely instantized formula including (in order of most abundant to least) L-leucine, Beta alanine, L citrulline malate, Glycine, Calcium and sodium bi carbonate we have a much more modern performance enhancer. Though extremely important to the muscle building / performance enhancing process, ingredients like Leucine, Beta alanine and citrulline can be found in many other competitive products. In my opinion what stood out was the emphasis on pH balance and the inclusion of bicarbonates. Using bicarbonates to buffer lactic acid build up is a fantastic addition to the formula allowing your muscles to push harder for longer. For those of you with a bit of an exercise physiology background, you can think of bicarbonates as pushing down on the hydrogen ions and maintaining a much more alkaline environment. Raising the muscles pH level and allowing your body to be much more equipped to handle the hydrogen ions produce during training.
With leucine kick starting anabolism, beta-alanine / glycine / bicarbonates working with each other to allow for greater endurance, lots of electrolytes and citrulline supporting proper blood flow to working muscles I would say we have a very well rounded formula.
Try OPUS out by itself first, even if you are an avid caffeine user, because I am and I could honestly use this product pre-workout without additional stimulants and have the same energy levels. If necessary you could stack it with a stimulated pre-workout product and have an even larger formula, but in my opinion it is unnecessary. If you do want to stack it I would stack it with something very basic, such as Animal Rage. They will compliment off of each other with caffeine rush from another product combined with the real physiological benefiting formula of OPUS. I found when used as directed it tasted great, so no recommendations for taste here.
