What is P.S.P.?

This is one of the most advanced non stimulant pre-workout supplements on the market today.

P.S.P. is a dosed-controlled non-stimulant pre-workout product designed to improve your energy during your workout and fueling your recovery post-workout. Along with its energy delivering muscle stimulating power, P.S.P. reduces fatigue and allows you to finish your workout strong. Using Metabolic Nutrition's 1 to 3 scoop serving suggestion, you determine the amount you use so that you can dial in your need based on the workout you are doing. The scientifically engineered combination of blood-pumping rapid absorbing ingredients, P.S.P. provides laser-like focus without the high stimulant post-crash drop off commonly seen in other pre-workout products. With P.S.P., getting skin-ripping pumps and blowing past your PRs has never been so easy.

How Does It Work?

The rapid absorbing ingredients in P.S.P. help to increase the nitric oxide response which increases blood flow to the working muscles. The increased blood flow gives you vein-splitting pumps but also acts to help with during-workout recovery, as well as providing a constant nutrient supply while you exercise. Metabolic Nutrition's Tri-PEP and glycogen-loading specific ingredients help provide the critical constituents to enhance muscle-building during your workout and will help continue the process post workout as well. They added specific ingredients to give you clear focus as to the task at hand so that you can work out longer and stay engaged. When using P.S.P., you will notice your energy does not drop off, which helps maintain power and strength, allowing you to work harder and stronger all the way through your workout.

Benefits of Electrolytes

Potassium, magnesium, calcium, and sodium are added to assist in the electrolyte balance between the intracellular and extracellular environment. In particular, the maintenance of precise osmotic gradients of electrolytes is important. Such gradients affect and regulate the hydration of the body as well as blood pH, and are critical for nerve and muscle function. Both muscle tissue and neurons are considered electric tissues of the body. Muscles and neurons are activated by electrolyte activity between the extracellular fluid or interstitial fluid, and intracellular fluid. For example, muscle contraction is dependent upon the presence of calcium (Ca2+), sodium (Na+), and potassium (K+). Without sufficient levels of these key electrolytes, muscle weakness or severe muscle contractions may occur. But to further enhance uptake, Metabolic Nutrition used specific glycerol-bonded forms of these electrolytes to help penetrate your muscle tissue providing stronger muscle contractions.

What’s Inside?

The combined ingredients within P.S.P. utilize a non-stimulant to provide energy, muscle-building, and fatigue fighting properties through its use of beta alanine and creatine, along with its branched chain amino acid combination. Specific forms of fast absorbing, high efficacy arginine silicate and agmatine sulfate compounds along with citrulline and a highly extracted form of glycerol, enhance blood flow and provide serious vein pulsing pumps. To control anxiety and help with focus, nootropics are included to improve neurotransmitter activity giving you better coordination and attention during your workouts. And finally, key minerals and electrolytes, have been added using a specific bonding to glycerol and gluconic acid to help improve uptake, maintain hydration, and give the appearance of fuller muscles. In all, P.S.P. has taken all the aspects of the pre-workout dilemmas, conquered them, and combined specific ingredients into one powerful non-stimulant product.

Difference Between P.S.P. and E.S.P.

The main differences between E.S.P. and P.S.P. is found in the use of stimulants, specific branched chain amino acids and arginine based aminos, as well as use of creatine. E.S.P. is Metabolic Nutrition's highly effective stimulant-based pre-workout to help you get amped up and ready for battle, where P.S.P., is their non-stimulant pre-workout designed to help you fight the battle both during and on the backside. P.S.P. combines different nootropics for focus and adds the amino acids and creatine to help focus on muscle development. As well P.S.P. uses a specific form of glycerol and arginine along with citrulline to help improve blood flow and provide a pump for those looking for that muscle-engorged feeling.

    Great pumps

    Love this stuff! Great product that works well when cycling of stimulant based pre workout drinks.


    Cant get better than this...Great price, Great taste, and Great energy for my workout!!

    Love to Stack It

    Love to stack the PSP with almost anything. My favorite right now is stacking it with Dust Extreme from Blackstone Labs. I just ordered fruit punch from both companies and together the best pre workout stack you could ask for. Nothing better on the market for the pumps at the gym nothing. One exercise and by muscles are swelled up like no other.

    Awesome product

    This is a great tasting pre workout. The blue raspberry is the best! The energy from just one small scoop is great; it's clean & long lasting. No crash afterwards either. I also like how you can choose from the small scoop or the larger scoop to adjust the potency.


    Awesome product to use when you're cycling off of a stimulant based preworkout.

    Taste really good

    PSP Pre Workout is a great pre workout. I had amazing pumps (up to 2 hours after my workout), lets of energy, increased Vascularity. I use 2 scoops 30 mins before workout and it starts kicking in during my workout. The pump was super crazy, it felt like my arms were gonna pop. This product doesnt have stimulants so it is a good product to try. Overall a good product.
