NutraBio PRE Stim-Free, as the name implies, is our stimulant free version of our PRE formula. We created PRE Stim-Free for those individuals who are sensitive to ingredients such as caffeine, hit the gym late at night, or otherwise want a pre-workout with the performance boosting ingredients found in PRE minus the stimulants.
Clinical doses of 15 research-backed ingredients
Beta-Alanine to increase endurance and help counteract fatigue caused by hydrogen ion accumulation.
Pharmapure creatine monohydrate for greater strength, power, and muscle growth. Creatine MagnaPower for increased solubility and absorption.
L-Leucine to help stimulate muscle protein synthesis, prevent muscle catabolism, and lessen recovery time between sessions.
Huperzine A to promote a strong mind-muscle connection and supercharge mental focus.
Betaine anhydrous to support creatine production, increase power and strength output, and protect cells from dehydration.
Agmatine sulfate and Nitrosigine to stimulate nitric oxide pathways leading to greater vasodilation and bigger muscle pumps.
Electrolyte and hydration optimizer that helps maintain water balance in the muscle, facilitates motor neuron function, and increase exercise capacity.
Leucine is one of the essential branched chain amino acids (BCAA). By itself it can stimulate muscle protein synthesis; the process responsible for muscle growth and recovery. This is why it is often referred to as the "main" amino acid. NutraBio's leucine is derived from fermented vegetables sources as opposed to animal based sources.
Beta-alanine (BA) is a version of the amino acid alanine which serves as the precursor to carnosine (ß-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.
Creatine is an amino acid (broken down protein) derived compound produced in the body that serves as the primary fuel source (ATP) for short duration, high intensity activities such as sprinting and weight lifting. Creatine is stored primarily in muscle tissue, and it is used for rephosphorylating ADP into ATP. This means that when our muscles use up our energy stores, creatine helps to replenish those stores in a fairly rapid manner. Approximately 2 grams of creatine are found in individuals that do not supplement and maintain a diet including animal based proteins. Those who do supplement can increase their body's internal creatine pool by 10 to 40% depending on diet and total lean muscle mass.
Betaine, scientifically referred to as Trimethylglycine, is a metabolite of choline. Betaine's two main functions in the body are as a methyl donor and osmolyte. As an osmolyte, betaine protects proteins, cells, and enzymes from heat, dehydration, and other physiological stresses. As a methyl donor, betaine is used to convert homocysteine to L-methionine, and is therefore, a precursor to creatine.
Malic acid plays a vital role in the Krebs cycle where it helps turn carbs, proteins, and fats into energy.
L-Citrulline is an amino acid that plays an important role in nitric oxide metabolism and regulation. It is converted to L-Arginine in the body to support L-Arginine and nitric oxide levels.
Agmatine Sulfate is a byproduct of Arginine through decarboxylation. It produces other byproducts that are involved in cell growth, structural and metabolic support to the nervous system.
Nitrosigine is a bonded complex of arginine and silicon that helps enhance nitric oxide levels to a greater degree compared to arginine alone.
Tyrosine is an essential amino acid whose primary role in the body is as the direct precursor to thyroxine and to the hormones dopamine, epinephrine, and norepinephrine. Tyrosine may improve both endurance and anaerobic performance via metabolic and/or neurotransmitter upregulation.
Choline Bitartrate is formed when choline is combined with tartaric acid. This increases the choline's bioavailability and in turn, makes it more effective. Increasing choline levels can produce a nootropic type effect as well as create longer and stronger muscle contractions.
Huperizine A is a selective inhibitor of the neurotransmitter acetylcholinesterase (AChE), which means it prevents the breakdown and increases the amount of acetylcholine; an important neurotransmitter in the central nervous system involved in cognition and muscular contractions.
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.
Calcium, potassium, and phosphorus are vital electrolytes needed to maintain bodily water balance and facilitate motor neuron function. The combination of these electrolytes in CALCI-K are highly soluble and readily absorbed by the body. Electrolytes have been shown to prevent muscle cramps and are essential to normal muscular contractions.
Suggested Use:As a dietary supplement, mix 1 heaping scoop of PRE into 12-14 ounces of water and consume 30-45 minutes prior to resistance training. Vary the amount of water to achieve your desired flavor level. DO NOT EXCEED 1 SCOOP IN ANY 24 HOUR PERIOD OR USE MORE THAN 5 DAYS IN ANY 7 DAY PERIOD.
