Tired of your pre-workout not giving you enough boost? StimMax is has been formulated to do exactly what the name implies, provide stimulants to the maximum! StimMax contains the most powerful ingredients and their analogs in highly efficacious doses. More than just a stimulant, StimMax contains potent nootropics for razor-sharp focus and attention as well as anxiolytic agents to give you all the blast you love without the feelings of stress and anxiety. Scientifically-validated ingredients in StimMax give you the burst of energy you need to perform at your MAX in the gym or any time you need a big pick-me-up.

Caffeine Anhydrous – The world’s most popular supplement in a whopping 425 mg per serving dose for superior energy, attention, and performance.

Choline Bitartrate – A precursor to the neurotransmitter, acetylcholine, which is responsible for neural signaling in the muscles and brain.

Huperzine A – Huperzine complements Choline Bitartrate by stalling the breakdown of acetylcholine, further increasing the nootropic and ergogenic effects of acetylcholine.

N,N-Dimethylphenethylamine Citrate – DMPEA is like DMAA, but safer. DMPEA increases neurotransmitter abundancy and function.

Methylliberine (as 40% Dynamine) – Methylliberine is a metabolite of caffeine and theacrine that has been reported as stronger than theacrine for even more focus.

These, along with 4 more, ingredients are the ultimate combination for the most powerful preworkout ever. StimMax is a real game-changer, firing on all cylinders for increasing energy, attention, focus, and performance in the gym. StimMax can also be used as a robust nootropic on any occasion that requires some serious productivity. Don’t allow yourself to miss out on the chance for an unparalleled preworkout experience – go with StimMax.


Choline Bitartrate

Choline is an important nervous system nutrient that serves as a precursor to acetylcholine. Supplemental choline can improve body composition, and it enhances several domains of cognitive function, such as attention and focus.

  • After one week of choline supplementation, weight-class athletes (martial artists) were able to rapidly lose weight in a safe manner while strength remained intact (Elsawy et al. 2014).
  • Knott et al. (2015) found a significant improvement in reaction speed, memory, and executive function in healthy participants.

Caffeine Anhydrous

Caffeine is the most popular stimulant in the world, and for good reason. Its effectiveness doesn’t stop at adrenaline and focus – it also improves power output, aerobic, and anaerobic exercise performance.

  • In trained athletes, Schneiker et al. (2006) observed that caffeine induced an increase in peak power of 7% and an increase in total work of 8.5%.
  • In rugby players, caffeine increased power output and testosterone by 21% (Beaven et al., 2008).
  • Brice and Smith (2001) observed an 18% improvement in alertness, supporting numerous other investigations on focus and attention.

N, N-Dimethylphenethylamine Citrate

N, N-Dimethylphenethylamine is a trace amine that is similar to DMAA. Due to its specific chemical structure, N, N-Dimethylphenethylamine is safer than DMAA without losing desirable focus and mood enhancement.

  • Xie and Miller (2008) have observed phenylethylamine as a potent dopamine agonist, increasing dopamine release and limiting reuptake, keeping more dopamine active in the system.
  • A meta-analysis of 20 studies has found improvement in gross cognitive ability following huperzine A supplementation (Yang et al., 2013).

Methylliberine (as Dynamine®)

Methylliberine is an alkaloid found in coffee and yerba mate and an analog of theacrine. Dynamine® is from the same ingredient supplier at Teacrine® and described by the supplier as a “harder hitting” Teacrine®.

  • Theacrine has been found to enhance the effects of coffee on feelings of attention, alertness, and focus (Kuhman, Joyner, and Bloomer, 2015).


Hordenine is an alkaloid that is an adrenergic and noradrenaline reuptake inhibitor. It increases the concentrations of noradrenaline, which improves focus, energy, and metabolism.

  • Frank et al. (1990) demonstrated adrenaline-like effects of hordenine in vivo, which support evidence that hordenine activates noradrenaline and its reuptake in an ex vivo model.
  • Important observations by Barwell and colleagues (1989) verified that oral hordenine is not broken down in the intestine and can be absorbed to increase active noradrenaline.


Higenamine is similar in structure to ephedrine and a powerful beta-1 and beta-2 adrenergic agonist that can enhance metabolism. Its acetylcholinergic effects also promote muscle and cognitive function.

  • Lee et al. (2013) found higenamine to increase lipolysis (+80%) and metabolic rate (+15%) vs. placebo.
  • Adrenergic-dependent release of acetylcholine by higenamine suggests higenamine is capable of improving motor function and muscular output (Nojima, Okazaki, and Kimura, 2000).

N-Phenylacetyl-L-Prolylglycine Ethyl Ester

Otherwise known as noopept, N-Phenylacetyl-L-prolylglycine ethyl ester is a nootropic similar to the racetam family but with better results.

  • A single dose of N-Phenylacetyl-L-prolylglycine Ethyl Ester has been found to produce a 70% increase in cognitive enhancement with an increase to 90% after 9 days (Ostrovskaya et al., 2001).
  • N-Phenylacetyl-L-prolylglycine Ethyl Ester also sensitizes neurons to choline, enhancing choline’s effects as well as neuroprotective factors like BDNF (Ostrovskaya et al., 2008; Tyler et al., 2002).

Sceletium Tortuosum (std. to NLT 0.5% alkaloids, 0.2% mesembrine)

Sceletium Tortuosum is an herb with anxiolytic effects. Supplementing with Sceletium Tortuosum or chewing its parent herb, Kanna, inhibits reuptake of serotonin.

  • Terburg et al. (2013) have found Sceletium Tortuosum supplementation to increase available 5-hydroxytryptophan, a metabolite of serotonin, which resulted in reduced anxiety.
  • Mesembrine is the primary active alkaloid in Sceletium Tortuosum, and effects are observed with as few as 0.35% alkaloids. The present contains at least 0.5%.

Huperzine-A (Huperzia Serrata 1% Extract)

Huperzine A is an acetylcholinesterase inhibitor, which means that less acetylcholine is metabolized, so high concentrations remain in the body. Acetylcholine in an important neurotransmitter for many parts of the central nervous system, including muscle contraction signals and cognition.

  • Zhao et al. (2002) demonstrated the high affinity of huperzine A to inhibit acetylcholinesterase and that it works as well or better than common pharmaceuticals.

Q: What is the best way to take StimMax?

StimMax is the most powerful preworkout available, so you may want to start with a half serving to assess your tolerance. Afterwards, take one serving in the morning or 30 minutes before training for increased energy and focus.

Q: What is N,N-Dimethylphenethylamine Citrate and is it dangerous?

N,N-Dimethylphenethylamine Citrate is an amine that is similar to DMAA. While still effective, N,N-Dimethylphenethylamine is much safer than DMAA due to its composition. It is recognized as safe by the FDA.

Q: What supplements pair well with StimMax?

For the total package in preworkout power, StimMax can be stacked with VasoMax for enormous boosts in energy and pump. StimMax is going to allow you to push your physical limits. A strong intra-workout like IntraMax will keep your muscles fed and anabolic throughout your workout.

Q: 425mg of caffeine sounds like a lot?

It sure does, but it’s actually within normal efficacious ranges for fit people. 3 – 6 mg of caffeine per kg of bodyweight is the recommended ergogenic dose, so anyone 71 kg (156 lbs) or heavier is right there at the top of the range. Some studies even suggest going up to 10 mg per kg.
