Performax PowerMax XT: Clinical Gains Now During Your Workout

Performax Labs PowerMax XT

Performax Labs has tweaked its daily muscle builder PowerMax XT to be a more comprehensive intra workout supplement.

Performax Labs has been on our radar for several years now, and we’ve really been impressed with the brand by its most recent releases including the revised formula for their pre workout HyperMax XT, and powerhouse nootropic formula NootropiMax.

Earlier, we covered the brand’s stim free pre workout / muscle building supplement PowerMax XT, which was incredibly well dosed and provided efficacious doses of all the daily muscle builders like creatine and betaine. Now, the brand has gone back and revamped PowerMax XT to be an intra workout formula.

This means you now take it during your workout as an “advanced sports drink”, as opposed to “any time of the day to get your creatine in”, although you can still do that if you wish.

The ingredient breakdown is just ahead, but first, take a moment to check the best deal and sign up for PricePlow alerts:

PowerMax XT Ingredients

Performax Labs PowerMax XT Ingredients

The new PowerMax XT has some notable changes and headlined by the addition of 9g of hydrolyzed whey.

The new version of PowerMax XT has several notable changes from the previous formula. The biggest changes come to PowerMax XT’s creatine, glutamine, creatinol-o-phosphate, and amentoflavone. Performax has traded creatine monohydrate and for a 3g blend of monohydrate, MCC, and creatine anhydrous. Additionally, they’ve completely removed amentoflavone and COP. So, let’s see what the new formula looks like..

  • Amino Acid / mTOR Activation (9g)

    The most notable addition to PowerMax XT is the addition of 9g of Whey Protein Hydrolysate containing all the essential amino acids, including the 3 BCAAs and headlined by a full 3g of Leucine.

    We reached out to Performax HQ to see why they included this particular form of whey, and they responded with:

    We used Whey Hydrolysate because the di/tri peptides can actually be utilized more efficiently than free form aminos, providing all the BCAA/EAA necessary in a better form. I see this formula being comparable to the old school SizeOn Pre Contest, except its open labeled and covers more bases.

    — Performax Labs Formualors

    Performax may be onto onto something here, as research has shown that consuming 6g Whey Protein + 3g/5g Leucine outperformed 25g straight whey in terms of myofibrillar protein synthesis.[1] Other research demonstrates that increasing the leucine content of EAAs (from 1.87g to 3.5g) and taken intra-workout increased post-workout muscle protein synthesis by 33% compared relative to the lower leucine content.[2]

  • Power – Strength – Recovery

    • Creatine (3g)

      Performax Labs Stack

      Performax has everything you need for all kinds of gains.

      Here’s an interesting little change from the original PowerMax XT — the brand has switched from 5g of pure creatine monohydrate to a 3g blend of monohydrate, magnesium creatine chelate (MCC), and creatine anhydrous.

      The most well known, and proven, muscle builder of all time, creatine monohydrate, leads off this cast of characters in PowerMax XT. Sure, Performax could have gone with one of the sexier forms of creatine such as Magnesium Creatine Chelate (which was in the original PowerMax), but instead they’ve gone with the form of creatine shown time and again to be the superior form. No other form of creatine has continually been documented to:

      • Increase power and strength[3,4]
      • Support lean mass gains[5,6]
      • Decrease fatigue[7]
      • Improve cellular hydration[8,9]

      You get the minimum full clinical dose of creatine (3g) from the three forms, but it’s important to remember that you’re not getting a full 3g of pure creatine, so you may want to add a little extra creatine to your pre or post workout drink.

      We often don’t see creatine in intra workout drinks, but we don’t see why not – any time is the best time. Glad to see it stuck, even with the switch to an intra.

    • Betaine Anhydrous (2.5g)

      Not enough love for Performax Labs out there. These guys are worth the attention!

      Betaine Anhydrous, a.k.a. trimethylglycine, is a proven power-booster that’s become a stalwart in most pre workouts hitting the market these days. There’s a good reason for this, as numerous clinical trials have documented its ability to enhance power, endurance, as well as protein synthesis.[10,11]

      Furthermore, betaine supplementation has also been shown to alleviate muscle soreness[12] and support creatine production in the body.[13]

      No underdosing at 1.5g here like we often see. This is the legitimate clinical dose used in studies.

    • L-Glutamine, L-Alanine, L-Alanyl L-Glutamine (2.5g)

      Don’t settle for average. Always perform to your MAX with Performax!

      L-Alanyl L-Glutamine is a combination of the two amino acids L-Glutamine and L-Alanine. This ingredient is most frequently encountered in post workout formulas due to Glutamine’s ability to quicken recovery and prevent muscular soreness.[14] Alanine’s attachment to Glutamine is due to its ability to improve the bioavailability and absorption of Glutamine[15,16], which otherwise glutamine would be degraded in the stomach before it could reach the intestines for absorption, thereby negating its recovery benefits.

      Additionally, L-Alanyl L-Glutamine (a.k.a. Sustamine) is also great for increasing cellular hydration and electrolyte levels, which lead to increased endurance and time to exhaustion.[17,18] This ultimately allows you to get more work done before succumbing to fatigue.

  • Hydration and Electrolytes

    • Taurine (1.5g)

      Taurine is a conditionally essential amino acid that gets depleted rapidly during bouts of high exercise. Although it’s stored in the brain, heart and muscle, we’re mostly interested in its actions on skeletal muscle.

      In muscle, taurine acts as a cell volumizer helping draw water and nutrients into muscle cells.[19] This improves overall hydration and gives more fullness to the muscle resulting in what we like to call “water-based” pumps. Additional research shows that taurine can alleviate symptoms of delayed onset muscle soreness (DOMS)[20] as well as heighten focus.[21]

    • HydroMax (1g)


      HydroMax is a high-yield glycerol that improves cellular hydration, endurance, and water-based pumps.

      When companies typically include glycerol products in their pre workouts, it’s almost always glycerol monostearate (GMS), which contains at most 25% glycerol. That’s not good enough for Performax as they’ve opted to include a much higher quality form of glycerol powder that is 65% glycerol.

      Much like our previous ingredient, glycerol turns your muscles into a sponge and enables them to absorb a lot more water, thereby improving both hydration and endurance.[22,23] As before, you’ll also get some great “water-based” pumps and much rounder, fuller shaped muscles!.

    • Sodium Phosphate (200mg) & Potassium Phosphate (150mg)

      To round out the hydration component of PowerMax XT, Performax includes two of the most important electrolytes in the body: sodium and potassium. These two electrolytes are vital for nerve, muscle, and CNS function and even as little as a 2% drop in hydration levels can lead to impaired performance and other undesirable consequences, like severe cramping!

In summary, everything’s well-dosed! As always, not enough love for Performax Labs out there. These guys are worth the attention!

Flavors Available

Performax PowerMax XT Increase

PowerMax XT is a one-stop shop for better performance, strength and recovery.

As great as PowerMax XT looks, unfortunately, it’s still only going to be available in one flavor: Orange Dream. Hopefully, if the newer version of PowerMax XT is a big seller for Performax, they’ll consider adding some additional flavors to the lineup in the not too distant future.


Performax continues its streak of developing properly formulated products, and this intra workout / muscle builder is no different. More people need to know about this brand. Athletes need to get in here too.

If you’re looking for a great stim-free pre to use while on a stim break, looking for a comprehensive muscle-builder, or you really want to amp up HyperMax XT’s experience…. PowerMax XT fits any scenario you could imagine.
