Czech Virus m3/s PUMP 362.5 g - Description
Do you go to the gym in the evening, but have to take pre-workout supplements with stimulants because you can’t get a good muscle pump without them? Solution: m3/s PUMP Our m3/s PUMP product is the answer for an intense pump during your workout, while also promoting quality muscle growth and deep sleep. Pre-workout supplements with stimulants are great, but if you don’t hit the gym until after work, they can affect the quality of your sleep. Most pre-workouts also rely solely on stimulants and don’t contain anything substantial to promote extreme muscle blood flow. Yes, Beast Virus® is the ultimate pre-workout and offers everything for stimulation, increased energy, strength, and even a muscle pump—BUT—when it comes to comparing the muscle pump effect, a comprehensive pre-workout can’t even come close to the m3/s PUMP product. It contains 10 perfectly synergistic ingredients in their purest forms and at optimal doses (or even higher, if the law allowed it!!) for the best pump ever!
Unlike other stimulant-free pre-workout supplements that contain a “proprietary blend,” m3/s PUMP is completely transparent. The content of each ingredient is fully disclosed. After all, it’s your body that’s receiving this supplement, so you deserve to know that you’re getting only the best! We create every supplement with this philosophy in mind: to develop a fully effective and as pure as possible supplement that we’d feel comfortable giving to our own families.
For connoisseurs, we recommend the ultimate combo—1 scoop of Beast Virus and 1 scoop of m3/s PUMP.
Stimulant-Free Pre-Workout Pump m3/s PUMP contains a massive 10 active ingredients. The most interesting aspect is that the product doesn’t rely solely on the classics you’re familiar with from today’s market. Most blends rely on arginine, creatine, and sugar to induce a pump! We rely directly on 10 active ingredients—WITHOUT SUGAR OR CREATINE. Each has a logical role in the formula and they complement each other perfectly. Just the base formula alone targets the pump through various mechanisms—L-Citrulline, L-Ornithine, AAKG, L-Arginine, and L-Lysine. We left nothing to chance; every possibility must be maximized to pump blood into the muscles like a machine. All of this is supported by glycerol and Sabeet®—a beetroot extract with a standardized nitrate content. The formula is rounded out by vitamin C and malic acid, which extend your endurance and push you to pump “until you’re red in the face” even during your last set! BioPerine® rounds out the formula—significantly enhancing the absorption of all ingredients. Naturally, it contains natural flavoring and no synthetic dyes. Sweetened primarily with steviol glycosides (a naturally derived sweetener from the stevia plant), with a small amount of sucralose. 0 fillers, 0 thickeners, 0 nonsense—none of which belong in a high-quality product!
Manufacturing and Ingredients All ingredients in m3/s PUMP are laboratory-tested for purity and the absence of banned substances. Production then takes place at a company with over 20 years of experience in dietary supplements and its own EN ISO 9001 and 22000 quality certifications.
Ingredients Under the Microscope
L-Citrulline
In the body, it is converted to arginine and then to nitric oxide (NO). According to research, citrulline can increase arginine and NO levels in the body more effectively than arginine alone. Arginine is broken down further in the body, whereas citrulline is already ready for absorption and use. Citrulline malate has been proven to boost energy; according to research, it increases ATP by 35%.
L-Ornithine
Enhances the effects of L-Arginine (and, logically, L-Citrulline as well) and creates a synergistic combination for muscle pump (nitric oxide delivery to the muscles) and growth hormone secretion.
AAKG
Consists of arginine and alpha-ketoglutarate for enhanced anabolism. AAKG increases blood flow to the muscles and works synergistically with L-Ornithine and L-Lysine.
L-Arginine
In its pure form, it complements the effects of the more potent L-Citrulline and AAKG; together with L-Ornithine, it enhances growth hormone secretion and improves blood flow to the muscles.
L-Lysine
It aids in the production of hormones and enzymes. It effectively blocks the unwanted side effects of arginine, making this product a completely safe option. Products containing arginine but no lysine can be potentially dangerous!
Glycerol
It draws water into cells extremely effectively. More glycerol inside muscle cells enhances the maximum pump you can experience. It also draws more water into blood vessels, causing them to dilate and increasing vascularity.
Vitamin C
It is the most well-known antioxidant in the world. However, it can also help with muscle pump. Higher doses of vitamin C slow the breakdown of NO2 and NO3, thereby helping to maintain the muscle pump for longer.
Malic acid
Plays a crucial role in improving overall muscle performance, alleviates muscle fatigue after exercise, and delays the onset of fatigue during exercise.
Sabeet®
(Beta vulgaris, 20-25:1 extract) contains a standardized amount of natural nitrates—2%. Nitrates are converted into nitric oxide (NO) in the body and improve blood flow and vascularity.
BioPerine®
(95% piperine) improves the absorption of other substances by 30 to 2,000%.
