This is the legendary Pre-Workout in which valuable geranium was used as the first on the market, with enormous power, which definitely made it one of the most popular products in the world.<br \/>\nIt contains the most effective ingredients from each category, responsible for completely different parameters during training.<\/p>\n<p>The special formula makes it extremely effective, therefore providing solid support for the daily workouts of top athletes. The supplement works extremely quickly, after a few minutes you can feel its effect. Ingredients with a stimulating and pumping effect are effective in increasing motivation and training energy. The addition of yohimbine will also reduce body fat even in stubborn places such as the abdomen, lower back, thighs.<\/p>\n<p><strong>Arginine alpha-ketoglutarate:<\/strong> participates in the formation of nitric oxide and therefore has the ability to dilate blood vessels, allowing better blood supply to muscles and soft tissues. It indirectly participates in the synthesis of cGMP, which, together with ATP, participates in the process of muscle contraction and has anabolic effects. Affects the secretion of growth hormone, supports the liver regeneration process, is an important precursor to creatine. Unfortunately, but the traditional form of Arginine is easily broken down in the stomach and therefore a small amount reaches its destination.<\/p>\n<p><strong>Creatine Monohydrate<\/strong> \u2013 One molecule of creatine and one molecule of water combined into one molecule is the best proven form of creatine for energy, strength, and muscle mass. Thanks to the highest quality micronization, it is absorbed much better than a traditional monohydrate, greatly increasing strength and muscle mass. Creatine performs a number of important functions in the athlete&#8217;s body, participating in energy processes and creating and maintaining an anabolic environment conducive to muscle growth.<\/p>\n<p><strong>Beta Alanine<\/strong>: A non-protein amino acid formed in the liver in the process of breaking down uracil. Essential in the synthesis of pantothenic acid, anserine and carnosine. The improvement in sports results is mainly observed in the action of carnosine (\u03b2-alanyl-L-histidine), whose production limits the availability of beta-alanine and whose synthesis is reinforced by the administration of said beta-amino acid from the abroad . Carnosine by accelerating the elimination of hydrogen ions from the body reduces acidification of the body.<\/p>\n<p><strong>Cafe\u00edna:<\/strong> tiene un efecto termog\u00e9nico y suprime el apetito, gracias a una mayor producci\u00f3n de adrenalina y noradrenalina. Se ha demostrado que aumenta la formaci\u00f3n de neurotransmisores en el sistema nervioso central como la dopamina, la acetilcolina o incluso la serotonina, lo que ejerce un efecto estimulante y aumenta la funci\u00f3n cognitiva. El efecto general de la cafe\u00edna en el cuerpo le permite mantener la efectividad del entrenamiento y mantener un estado de \u00e1nimo positivo, a pesar del d\u00e9ficit de calor\u00edas.<\/p>\n<p><strong>2-Aminoisoheptane HCL:<\/strong> -is a stimulant that has other names, such as dmha or octodrine. <strong>DMHA<\/strong> works as a bronchodilator, which increases our aerobic capacity, in addition, it has decongestant activity (narrowing of blood vessels, causing an increase in the rate of oxygen flow), does not cause &#8220;stupidity&#8221; and sharpens the senses that could not always be experienced with the dmaa<\/p>\n<p><strong>Geranium Extract:<\/strong> \u00a0Stimulates the process of reducing body fat and helps increase training intensity.\u00a0Geranium, after penetrating the nervous system, stimulates the release of dopamine, thanks to which it provides concentration and a <strong>good mood<\/strong>, which is crucial during training.<\/p>\n<p>Remember that having this ingredient does not mean MADNESS in stimulation, it will not make you nervous. These products are not sold in a physical store.<br \/>\n(There are other pages that are copying even our description, nor do they take the time to put their own experiences or knowledge)<br \/>\nWe have been there for more than 9 years. Be careful.<\/p>\n<p><strong>Yohimbe Extract<\/strong>: a substance that is useful to combat the so-called refractory adipose tissue, located mainly in the chest and waist area in men, as well as on the hips, buttocks and thighs in women. Yohimbine works by <strong>blocking \u03b12 receptors<\/strong>, which clearly facilitates weight loss and is useful for carving weight loss-resistant body parts. It is worth remembering that the effect of yohimbine effectively reduces insulin. Therefore, taking this compound around carbohydrate meals does not make sense. Yohimbine is particularly effective when used on an empty stomach, before exercise.<\/p>\n<p><strong>Schisandra Chinensis<\/strong> &#8211; has a strengthening effect on the body, supports liver function, cleanses accumulated toxins. It has a positive effect on the heart, brain, lungs and kidneys. In addition, it accelerates the metabolism, which prevents the accumulation of unnecessary fat.<\/p>\n<p>\u2192 Before trying any new Pre Workout product, you have to have a <strong>MINIMUM of 4 days without Stimulants in your body<\/strong>, to keep the receptors fresh, <strong>THIS IS A BASIC that<\/strong> every consumer should know.<\/p>\n<p><strong>Dosage:<\/strong><\/p>\n<p><strong>1<\/strong> to<strong> 2<\/strong> servings 30 before training. <strong>1 scoop<\/strong> is to go very well with energy,<strong> 2 scoops<\/strong> is strong that some could not tolerate and <strong>3 scoops<\/strong> is only for those who are stim junkies.<\/p>\n<h6><\/h6>\n<p>American Muscle Fit is not responsible for health problems caused by incorrect dosage.<br \/>\nThese Products are NOT sold in a physical store<br \/>\nThe consumption of the products purchased on this page is entirely under your own responsibility.
