While many companies boast about having a lot of fancy sounding ingredients in their formulas, we understand that quality and quantity matters too. It’s not always about cramming everything you can into one formula. You must have enough of the right ingredients for someone to feel their effects. MFX PRE is perfectly dosed to ensure that you’re getting more than just a name drop, you’re getting enough of everything you need to dig deeper and train harder through even the toughest workouts.


Arginine AKG 2:1

Arginine alpha-ketoglutarate (AAKG) is a salt formed by combining two molecules of the amino acid L-Arginine and one molecule of alpha-ketoglutarate. L- Arginine is a nonessential amino acid that influences several metabolic factors that are important to athletes. AKG (alpha-ketoglutarate) is the nitrogen-free portion of the amino acid and it is formed in the Krebs cycle; the energy-producing process that occurs in most body cells.

The alpha-ketoglutarate version of arginine is more efficient. When you combine these two things it’s more easily absorbed, plus you get the benefits of both compounds.

CarnoSyn® beta-alanine

CarnoSyn® Beta-alanine (BA) is a version of the amino acid alanine which serves as the precursor to carnosine (β-alanyl-L-histidine) in skeletal muscle. Supplementing with BA is a highly effective means of increasing muscle carnosine content. Increased muscle carnosine helps buffer the negative side effects of hydrogen ion accumulation in muscles as exercise intensity increases.

NO3-T® Betaine Nitrate

NO3-T® Betaine Nitrate increases vasodilation by metabolizing its nitrate molecules in the body into Nitric Oxide. 


AgmaPure® Agmatine

AgmaPure® is the unique green, high purity agmatine sulfate. It’s produced by a natural biological process and away from the neurohazard impurity Arcaine, which exists in almost all the other brands of Agmatine Sulfate. Agmatine Sulfate is thought to improve nutrient partitioning thus leading to more glycogen storage and increased water retention within the muscle. It also increases the level of nitric oxide (NO), which can increase the "PUMP" that athletes look for when weight training.


Taurine is one of the most important, useful, and safest amino acids.  Taurine is best known for its beneficial effects on the heart and cardiovascular system. Early clinical research also suggests that taurine, in combination with caffeine, can produce improvements in mental performance.  When the body engages in extreme physical activity, it no longer will be able to produce the necessary amounts of taurine, therefore supplementation becomes necessary.


L-Tyrosine helps to activate metabolic pathways that produce hormones epinephrine and norepinephrine. These hormones are typically produced during moments of stress on the body and provide a boost of adrenaline, giving you that fight or flight feeling. Epinephrine and norepinephrine are depleted quickly during these moments of stress due to a lack of L-Tyrosine.

The addition of this amino acid will help give you an extra PUSH and can make a big difference to help you FIGHT through your workouts and plateaus.


L - Alanine is a non-essential amino acid that plays a critical role in protein synthesis and other metabolic processes, including regulating blood sugar.
