Opus Ingredients

Magnum OPUS Ingredients

OPUS provides your body with the raw materials to ignite your anabolic furnace and keep it churning through the duration of your whole workout. Note the scoop/serving sizes – 1 for “budget” mode, 2 for “max” mode!

Opus is much different from your typical BCAA / intra workout supplement. It contains a unique mix of other amino acids, ergogenic aids and hydration agents to help you grind out those all important final muscle-building reps.

Important note regarding dosing: Below, we write what’s in each scoop. But note that there are 48 scoops, and the preferred serving size is two scoops. So you can multiply everything by two if you want the max dosing. You can stick to 1.5 scoops for “budget mode”.

Opus used to contain a partial prop blend, but they’ve updated the label to make it now completely 100% transparent, something we’re HUGE fans of here! We used to think we were getting plenty of the important ingredients in OPUS, but now we’re definitely certain we like what we see:

  • Instantized L-Leucine (2g / 4g)

  • Leucine is one of the three Branched-Chain Amino Acids (BCAAs), and perhaps the most heavily researched. It’s known as the “anabolic trigger”[1].

    Leucine kick starts the mTOR Pathway[2], which stands for Mammalian Target of Rapamycin, the all-important muscle-building pathway in the body.

    Leucine is also heavily involved in energy metabolism and glucose uptake in the body.[3] Supplying your muscles with a healthy dose of leucine just prior or during your workout will provide them with the essentials they need to avoid going catabolic and set you on the path to a great workout.

  • Instantized CarnoSyn Beta Alanine (1.6g / 3.2g)

    We’re always happy to see beta alanine, whether it be a pre, intra, or post supplement. We’re big fans of it in nearly any athletic or performance situation since it acts as a pH lactic acid buffer. This reduces lactic acid breakdown and heightens muscular endurance and power.[4,5]

    As there is only 1.6g in one scoop OPUS, we’d recommend adding at least 2g of extra beta alanine at some other point in the day. OR, just take the recommended two scoops!

    The good news is that either way, pre workouts typically offer an extra bit, so OPUS is a great way to fill the gaps from those too!

  • Instantized L-Citrulline Malate (1.5g / 3g)

    Krebs Cycle Acids

    OPUS supplies the necessary acids to keep the Krebs Cycle in constant motion so your never without energy during your workout.

    This combination of L-Citrulline and Malic Acid has become incredibly popular with nearly all new pre and intra workouts hitting the market over the past 18 months. Much like beta alanine, we’re big fans of this ingredient as well.

    Citrulline Malate (CM) is a key factor in the urea cycle which helps to remove ammonia buildup from the body. The end result of this increased energy production, improved stamina, better recovery, less fatigue and increased blood flow to muscle.[6,7,8,9] All of this adds to improved workout performance and more muscle-growth!

  • Instantized L-Glycine (1.25g / 2.5g)

    Glycine is a non-essential amino acid that is readily available in most high-protein foods. It also happens to be the simplest of the 20 amino acids. This doesn’t mean it’s not important though.

    Glycine is involved in a number of functions in the body, most notably: converting glucose into energy and increasing the body’s creatine levels.[10,11] Better glycogen storage frees up glucose for energy needs during your workout making sure you never “bonk” and have to end the workout early due to depleted energy levels.

  • Instantized Calcium Carbonate & Sodium Carbonate (500mg / 1g each)

    Carbonates are molecules that act as buffering agents in the body. Similar to beta alanine, carbonates prevent the accumulation of acidity in the muscles leading to higher endurance and increased performance.[12,13,14]

  • OPUS’ Remaining Ingredients

    The remaining constituents inOPUS contains electrolytes, vitamins, and minerals to help sustain your energy and hydration levels ensuring optimal performance.

    The Krebs Cycle is one of the most important cycles in the body that’s responsible for the breakdown of glucose, fatty acids, and amino acids. The breakdown of these components yields energy for the body. To keep the cycle running at optimal levels, there are several acids that must be used during the various reactions.[14] These acids (Citric Acid, Alpha-Ketoglutaric Acid, Malic Acid, Fumaric, and Succinic) just happen to be the same ones Magnum has included in OPUS.

    More phosphates to get more done

    As we all know, ATP (Adenosine Tri-Phosphate) is the molecule that the body uses as its energy source when exercising.[15] When ATP is broken down for energy, it’s the phosphate molecule that’s severed from ATP and is needed to replenish in order to regenerate your energy reserves. For this reason, Magnum included several different phosphates to keep ATP levels topped off ensure you have to end a set early due to fatigue.

    Finally, Magnum includes the B-complex vitamins to round out the formula. The B vitamins are heavily involved in energy metabolism and production in the body. They don’t call them essential vitamins for nothing. In addition to helping breakdown carbs for glucose use in the body, B vitamins are also used as co-enzymes to breakdown proteins and fats which helps support optimal nervous system functioning.

Flavors Available

Magnum Nutraceuticals OPUS Orange Dreamsicle

Orange Dreamsicle is the newest flavor of OPUS sure to whet your appetite and fuel those intense workouts.

As we highlighted above, OPUS is available in the brand new Orange Dreamsicle, but that’s not all, it’s also available in Blue Yasberry and Cellular Punch. Each bottle contains 48 scoops to help “pHuel” your workouts.

If that’s not enough, Magnum provides dosing instructions based on your weight. If you’re under 130lbs, take 1 scoop and if you’re over 130 lbs, it’s recommended to use 2 scoops.

A stimulant-free pre workout alternative?

Some of the best intra workouts can even be used as a non-stimulant pre-workout (especially for night trainers) — and OPUS is definitely in that kind of category. So if you’re tired of getting stimmed out or have to work out at night, this may easily get you through a rough workout.

For an even greater anabolic firestorm, consider stacking it with the Hi5 BCAA supplement!


Magnum has delivered one stellar intra workout product that not only provides your body the raw materials to ignite your anabolic furnace but also supply the critical nutrients your body needs to keep all of its energy producing cycles functioning at their highest levels. This is definitely one of the most unique and intriguing formulas we’ve seen from an intra workout standpoint.

Our key takeaway is that this is a product that’s really meant for those who bust their butts in the gym or on the field. If you have lazy workouts and never work up a sweat, this probably isn’t for you. But if you get doggedly tired through incredible, self-punishing workouts — and you know who you are — then OPUS is an intra workout that will put a lot back into your tank.

The effects should be quite noticeable and it’s this unique blend that really separates it from the typically BCAA-focused intra workout supplement. Give it a try today if you feel your energy levels have been waning during your recent workout sessions and let us know how it helps!
