When you arrive to the gym, you want to get the most oout of your workout. Having the right exercise regimen and the right mindset – pushing yourself to your absolute limits – are an essential part of the equation. Diet and supplementation also play a huge role – you need an intra-workout that will be replenishing what you need while supporting your gains in mass and strength. That is why Performax Labs has developed IntraMaxTM, the ideal formula for your intra-workout. First, we start with whey hydrolysate and leucine, which will maximize your muscle protein synthesis while digesting quickly and easily so you don’t slow down. Next, we deliver next-level osmolytes, which have the dual action of hydrating and swelling the muscle which instigates further growth! To finish off with replenishment, IntraMaxTM contains equal parts sodium and potassium, so that you are fortifying your body in a balanced way.


  • Amino Acid/mTOR – Combining 6g of a fast-digesting protein with added leucine is as effective at increasing muscle protein synthesis as 20g of whey protein.
  • 3 forms of creatine – Different forms of creatine utilizing different transport pathways to ensure maximal uptake and growth in muscle mass and strength.
  • L-Alanyl-L-Glutamine – A dipeptide that improves hydration and intestinal absorption of nutrients while lowering fatigue.
  • Betaine – A tripeptide that improves workout volume and hydration
  • Hydromax – A patented, super-concentrated form of glycerol that drives superhydration for intense, prolonged workouts.
  • Sodium/Potassium ratio – Essential to replenish electrolytes that are lost in sweat.

IntraMaxTM is an ideally formulated product that gives you exactly what you need to sustain and maximize your workouts. What truly sets IntraMaxTM apart is the combination of 6 grams of whey hydrolysate plus leucine – an ideal combination of the exact amount of amino acids needed to maximize muscle protein synthesis while being light on your digestive tract so you can feel energized rather than bogged down. Add to that the multiple hydration enhancers, from creatine to betaine to Hydromax, and you will experience maximal muscle hardness and fullness, which translates to lean mass and strength gains. Once you add IntraMaxTM to your supplement regimen, you will not want to lift without it again.

Supplement Facts


Whey Protein Hydrolysate

A hydrolyzed protein means that water has been used to break up the protein into smaller components, such as di- and tri-peptides. This results in faster and easier digestion, allowing the body to absorb and utilize the amino acids more easily and efficiently.

  • Tang et al. (2009) demonstrated how ingestion of hydrolysate increases protein synthesis at rest and during exercise significantly more than other milk and plant proteins.
  • Buckley et al. (2010) showed that hydrolysate improved recovery of muscle strength after intense exercise better than whey isolate.



Leucine is an essential amino acid that is required as a building block for building muscle. More importantly, it activates muscle protein synthesis via the mechanistic target of rapamycin (mTOR) signaling cascade.

  • Koopman et al. (2005) showed that protein with added leucine will increase post-exercise protein synthesis significantly more than protein alone.
  • Anthony e al. (2000) investigated the mechanisms behind leucine’s role in muscle growth and demonstrated that leucine can activate eIF4F, a component of the mTOR signaling cascade.


Creatine Monohydrate

More evidence exists that creatine is safe and effective for exercise performance than any other supplement on the market. Hundreds of studies support that creatine improves power, strength, muscle mass, hydration, and performance of high-intensity exercise. Creatine monohydrate is the most researched form of creatine available.

  • A meta-analysis (2003) of 100 studies showed significant benefits on body mass and lean body mass from creatine supplementation.
  • Del Favero et al. (2012) showed that 10 days of creatine supplementation significantly increases the 1-repetition maximum in both bench press and squat, indicating that both upper and lower body strength increase after creatine consumption.


Magnesium Creatine Chelate

Magnesium creatine chelate is a unique form of creatine that is absorbed into the muscle through a different transport mechanism than monohydrate. Pairing it with monohydrate produces synergistic benefits by increasing overall transport and effectiveness of creatine.

  • Consumption of magnesium creatine chelate for two weeks increased quadriceps strength and muscular hydration compared to creatine plus magnesium, suggesting that the chelate increased transport into the muscle.

Creatine Anhydrous

Creatine anhydrous is the same as creatine monohydrate, but without the water molecule attached. Therefore, each gram of creatine anhydrous contains more creatine than creatine monohydrate. Creatine anhydrous is the purest form of creatine available.



Glutamine is the most abundant amino acid in the body, and is utilized for multiple functions, including muscle building, protein synthesis, cellular energy, and neurotransmitter production.

  • Street et al. (2011) found that glutamine supplementation improved recovery of strength and reduced muscle soreness in active men after intense exercise.
  • Legault et al. (2015) investigated the recovery benefits of glutamine in men and women and confirmed the findings from Street’s lab.
  • Sasaki et al. (2013) observed that immune system function – which can be compromised after intense exercise – was improved after glutamine supplementation in elite athletes.



Alanine is another abundant and important amino acid. Not only is it necessary for muscle building and protein synthesis, but it also plays a major role in fuel regulation by helping the liver to adjust glucose and nitrogen. In this way, it protects the muscle from being cannibalized during intense exercise.



A dipeptide of alanine and glutamine, L-Alanyl-L-Glutamine has demonstrated unique properties that can benefit hydration and intestinal health.

  • Hoffman et al. (2010) showed that L-alanyl-L-glutamine reduced fatigue and improved reaction time and shooting skill after a 40-minute competitive basketball game.
  • Leite et al. (2013) demonstrated that L-alanyl-L-glutamine improved intestinal permeability, which could improve the digestion and absorption of other biomolecules and improve immune health.


Betaine Anhydrous

Betaine, or trimethylglycine, is a tripeptide that can benefit athletes in multiple ways. As an osmolyte, it will improve whole body and intracellular hydration. It can also support anabolic hormones to keep you building muscle throughout the workout.

  • Trepanowski and colleagues (2011) observed an increase in training volume and oxygenation of the muscle.



Taurine is an organic acid that help the body in a variety of ways. It stabilizes membranes, which can benefit every cell in the body, especially regarding the heart and nutrient transport. Taurine is generating a lot of interest around its ability to improve carbohydrate delivery and lower blood glucose. It also improves antioxidant status.

  • Zhang et al. (2004) demonstrated that taurine supplementation can improve time to exhaustion, VO2Max, and lower oxidative stress in healthy young men.
  • In a study by Moloney et al. (2010), taurine increased blood flow via improved endothelial function.



Hydromax is a patented, super-concentrated form of glycerol, which is an osmolyte that will improve hydration via increased intracellular uptake into the muscle. The resultant swelling of the muscle will also stimulate satellite cell recruitment, resulting in muscle growth.

  • A recent meta-analysis by Goulet et al. (2007) concluded that hyperhydration with glycerol enhances prolonged exercise performance under hot conditions.


Sodium Phosphate

Sodium is such an important electrolyte, since over 90% of the electrolytes lost in sweat are sodium. Sodium is the “electrical power” of neurons, so every muscular contraction depends on proper sodium availability.

  • Hyponatremia can result from intense, prolonged exercise with hydration but without electrolyte replenishment. Symptoms include: nausea, headache, confusion, and fatigue.


Potassium Phosphate

The “yin” to sodium’s “yang,” potassium acts with sodium, so is equally necessary. When sodium rushes into a cell (powering neurons, for example), potassium rushed out, so both must be kept in perfect balance.

  • Though not as much potassium is lost in sweat as sodium, there are still losses, and it is not found in the diet as much as sodium – therefore many people have deficiencies. Low potassium, or hypokalemia, results in cramping, weakness, tiredness, and in severe cases, inability to move arms and legs.


Q: How do I take Performax Labs’ IntraMax?

A: Take one serving during each workout. All the ingredients are clinically researched for safety, so IntraMax can be taken multiple times per day.

Q: How does Performax Labs’ IntraMax differ from other intra-workouts?

A: Performax combines 6 grams of whey hydrolysate – a fast-digesting whey protein high in EAA’s – with leucine – a major stimulator of muscle protein synthesis. This combination has performed as well as 20 grams of whey protein for building muscle, but is much easier on the gastrointestinal tract – ideal for intra-workout use. No other intraworkout can replace your post-workout protein like IntraMax can.

Q: What other Performax Labs products can I stack with Performax Labs’ IntraMax?

A: Check out our Mass Stack, which combines IntraMax with SlinMax, AlphaMax, and MassMax XT to keep your body anabolic and building muscle. Also check out our Complete Stack and our Low Stim Stack.

Q: When is the best time to take Performax Labs’ IntraMax?

A: The best time is during your workout, whenever that happens to be. There are no stimulants in this product, so it can be effectively taken morning, noon, and night.
