Primeval Labs EAA Max: A Full-Spectrum Intra Workout

Primeval Labs EAA Max

After much anticipation and fan demand, Primeval Labs has finally released a comprehensive essential amino acid intra workout in EAA Max.

The intra workout category of sports supplements have exploded in recent years, and now rival pre workouts and protein as the most sought after products around. The problem is, the vast majority of intra workout products on the market are comprised solely of BCAAs, which while beneficial, aid muscular energy sources, but not as much in the way of total muscle building.

Primeval Labs has been on a tear recently with their new products such as Pyretic, the new flavors of Adrenal Rush V2, and the Gray Matter nootropic, but some customers wanted a lower-carb intra workout supplement than BIOS3 Intracell 7 that came without the pump ingredients.

Well, that day has finally arrived as Primeval has released EAA Max, a truly superior intra workout supplement that not only boosts endurance, but also supports lean muscle growth thanks to the full spectrum of essential amino acids the formula provides.

EAA Max Ingredients

EAA Max is substantially different from your typical BCAA-only intra workout you usually see pedaled around the industry. In addition to the gold standard 5g dose, EAA Max also contains a full complement of essential amino acids, hydration aids, and endurance boosters to provide a product that truly does enhance workout performance and muscle building.

By saving costs in removing the expensive Cluster Dextrin carbs and NitroSigine NO booster from BIOS3 Intracell 7, Primeval was able to take that and add in the EAAs — but don’t miss the last ingredient, ribose either!

  • BCAA 2:1:1 (5g)

    Primeval Labs EAA Max Ingredients

    EAA Max includes a full spectrum of BCAAs and EAAs to support muscle endurance AND muscle growth during your most intense workouts.

    Primeval starts off EAA Max the research-backed ratio of 2:1:1 BCAAs, which provides you with 2.5g of Leucine, 1.25g of Isoleucine, and 1.25g of Valine.

    Leucine is well-known as the primary stimulator of the mTOR pathway in the body[1], that keeps you anabolic (muscle-building) during your workouts. This helps spur muscle growth without having to consume endless amounts of protein. Plus, BCAA consumption also helps speed recovery and prevent the onset of muscle soreness, also known as DOMS.[2,3]

  • Essential Amino Acids

    Enter the section of things you get in complete proteins, but you don’t get in your standard BCAA-only drink:

    • L-Lysine HCl (300mg)

      L-Lysine is an essential component in the production of carnitine — a compound used by the body for converting fat to usable energy and cholesterol level regulation. In EAA Max, lysine aids in muscle protein synthesis, calcium absorption, and recovery.[4,5]

    • L-Threonine (225mg)

      Threonine is ɑ-amino acid necessary for the construction of proteins. Specifically, threonine is needed for the synthesis of glycine and serine, which is then used to stimulate muscle protein synthesis (MPS) in the body.[6]

    • L-Phenylalanine (200mg)

      Phenylalanine is a precursor to Tyrosine that’s subsequently converted other more potent neurotransmitters including the likes of epinephrine (adrenaline), norepinephrine (noradrenaline), and L-Dopa. These 3 powerful neurotransmitters improve mood and energy, both of which will be needed during intense workouts.[7]

    • L-Tryptophan (50mg)

      Primeval Labs EAA Max Adrenal Rush V2

      The perfect workout combo — Adrenal Rush V2 for pre and EAA Max for intra!

      Tryptophan is a welcome ally during tough workouts as it increases pain tolerance levels. Additionally, this essential amino acid boosts overall mood.

      Don’t get scared about the whole “tryptophan makes you tired” Thanksgiving nonsense. Just because it increases serotonin doesn’t mean it’ll make you tired in the middle of the day – especially when in workout mode!

      And just so you know, 3oz of turkey has 250-300mg tryptophan, so this is just a small dose to make sure it doesn’t bottleneck your body’s biological reactions that may be requiring it.

    • L-Histidine (25mg)

      If you’re a beta alanine user, then listen up! We all know that Beta Alanine boosts endurance via increasing levels of the intracellular buffer carnosine, but BA is only ½ of the carnosine “equation”.

      In order to form carnosine, beta alanine must bind to histidine in skeletal muscle. Histidine deficiency prevents adequate carnosine production[8], which leads to less than optimal endurance. Suffice it to say, that if you’re wanted the benefits of BA, make sure you’re getting enough Histidine as well, either through diet or supplementation!

    • L-Methionine (20mg)

      Methionine is first and foremost an antioxidant which helps prevent the spread of free radicals and oxidative damage brought on by intense periods of training. It also functions as a precursor to the amino acids L-Taurine and L-Cysteine, both of which aid performance.

  • Muscular Energy & Nutrient Delivery

    • Cluster Dextrin (2g)

      Primeval Labs EAA Max Ice

      Really want to accentuate the subtle flavors of EAA Max, serve it over ice — cocktail style!

      Cluster Dextrin is the patented form of highly branched cyclic dextrin (HBCD),the most popular intra workout carbohydrate around.

      HBCD is created from the the breakdown of amylopectin. It has a low osmolality and high molecular weight which means it passes through the stomach insanely fast, but doesn’t lead to any “heavy” feeling or GI upset.[9]

      This is exactly what you want for an intra workout carb. HBCD is in and out of the stomach quickly, and onto the small intestine, along with the rest of the amino acids in EAA Max, which mean faster absorption into the bloodstream and into your muscle where it helps prolong endurance, offset DOMS, and improve pumps![10,11]

      Now obviously 2g isn’t going to do much, but it’s here for a reason — as a shuttling agent, especially for the D-Ribose next. Note that this is still low enough to keep you in keto, so even if you’re an ultra-low-carb dieter, 2g won’t devastate your plans.

    • D-ribose (500mg)

      EAA Max StephFitMum

      You know Primeval athlete StephFitMum is getting in on this action for her lifts!

      Ribose is a sugar generated in the body from glucose. D-Ribose is a supplemental form of the sugar that when ingested combines with adenine to form ATP, the primary component of cellular energy. During intense exercise, ATP levels get rapidly depleted due to the demands placed on the muscle.

      D-Ribose has been shown to be extremely effective in rapidly replenishing ATP stores following exhaustive bouts of exercise.[12,13]

      This is one of the more unique ingredients here and it’s a bummer to see it last. Ribose is often sold to enhance energy (especially in “sluggish” people with poor diets), but isn’t often in these supplements where additional energy could be used.

      It’s a worthy ingredient to try in training mode, and you may get a good kick out of it.

Mike’s EAA Max Review

Mike took to the three flavors, and decided that strawberry mango was best for his sweet tooth. But here’s the real deal – we’re still sticking with BIOS3 Intracell 7.

On the Formula

As you noticed, EAA Max contains substantially more than just a simple 2:1:1 ratio — there’s also a full EAA profile, which makes it a much more effective product rather than just providing muscular energy from BCAA’s. We asked Primeval what was the driving force / inspiration for this particular formula, to which they responded:

“We really wanted to deliver a quality EAA to the market that both delivered in formula, as it should, and in taste as we know customers typically drink Amino formulas all day.”


Primeval enthusiasts have been clamoring for quite a while for an amino acid product and the simple fact of the matter was that the brand wanted to do something truly effective and not just copy the rest of the industry. Plus, Leucine is surprisingly hard to flavor, and Primeval wasn’t releasing a product until they had not only developed one of the most effective products on the market, but also one of the best tasting amino acid products on the market.

Well, EAA Max is well worth the wait, as it comes in the following flavors:

    Two intras from Primeval

    So now you have Intracell 7 / Intracell 7 Black and EAA Max. They can be stacked together if you got the funds, but we think this is a bit more of a “one or the other” situation. If you want to weight train with carbs, BIOS3 still brings the thunder there – 15g Cluster Dextrin and NitroSigine.

    But if you’re low-carbing it or doing endurance activities (and can handle your own carb game), EAA Max is likely the new intra workout go-to from Primeval!


    Intra workout supplements are often “poo pooed” by many in the community that see them as simply unnecessary given ample pre workout nutrition. Many people want complete proteins. BCAAs are fast but they’re not complete, and that’s not good enough for everyone. Those individuals may want to give intra’s another shot, the EAA Max way.

    Primeval Labs has developed a truly effective intra workout supplement that not only boosts endurance and decreases soreness, but also provides enough supporting ingredients to enhance natural muscle growth. And some people simply wanted BIOS3 IntraCell 7 but without so many carbs or pump ingredients – and if that’s you, then you’ve got it – and then some.
