Skull Labs Skull Crusher Stim-Free - 350 g
Skull Labs Crusher Stim-Free is an excellent option for individuals seeking a pre-workout supplement without stimulants. The formula is free from caffeine and other energizing ingredients, making it ideal for evening workouts without disrupting sleep. The supplement is a well-thought-out blend of nitric oxide boosters, amino acids, glycerol, nootropics, and B vitamins, ensuring multidimensional support during training sessions. It is recommended for physically active individuals—both amateurs and professionals—who aim to push their limits and overcome obstacles on the path to achieving their goals.
The formula’s inclusion of citrulline malate is particularly beneficial for increasing nitric oxide levels in the body. This leads to improved blood flow, which results in better muscle pumps and more efficient nutrient delivery during workouts. The addition of beta-alanine helps buffer acid buildup in muscles, reducing fatigue and allowing for longer, more intense training sessions. Meanwhile, the presence of AAKG (arginine alpha-ketoglutarate) works synergistically to support vasodilation and enhance the muscle pump. Together, these ingredients create a powerful combination that promotes increased strength, stamina, and recovery.
The product delivers uncompromising pre-workout effects thanks to the optimal proportions of 12 active ingredients. Its stimulant-free formula offers a perfect alternative to pre-workout supplements containing energizing components. For example, supplementation with citrulline malate has beneficial applications for increasing nitric oxide (NO) levels. This contributes to improved overall performance, enhanced exercise capacity, positive effects on the circulatory system, and reduced signs of fatigue associated with physical activity.
Beta-alanine, a key precursor of carnosine, enhances its production and increases its presence in the muscles. This supports optimal muscle pH levels, induces an ergogenic effect, and aids in building lean muscle mass. AAKG (arginine alpha-ketoglutarate) may assist in improving body composition, supporting certain exercise parameters, and influencing hemodynamic factors, such as blood pressure.
Betaine supplementation is believed to play a valuable role for physically active individuals, aiding in their performance and recovery. Niacin and vitamin B6 support the proper functioning of the nervous system, help maintain optimal energy metabolism, and contribute to reducing fatigue. Additionally, choline and vitamin B6 assist in maintaining proper homocysteine metabolism.
The supplement contains taurine, which aids in energy metabolism and helps prevent muscle breakdown, while betaine supports muscle protein synthesis and circulatory health. The nootropic effects from ingredients like L-tyrosine, choline bitartrate, and alpha-GPC further optimize mental clarity and focus during training. These compounds work together to improve cognitive function, reduce stress, and maintain mental resilience, ensuring that users can train with full concentration and energy. The formula is rounded off with vitamins like B6 and niacin, which support overall metabolic function and help reduce fatigue, making Skull Crusher a comprehensive and balanced pre-workout option for those seeking to maximize their physical and mental output.
The Skull Labs Skull Crusher Stim Free pre-workout booster is a solution created for those starting out with pre-workouts. Its formulation is more akin to a no-booster, but the nootropic additives will also support nervous system function. Skull Labs Skull Crusher Stim Free will effectively intensify the muscle pump effect, allowing you to feel your muscles fill with blood during exercise. The increase in strength and endurance allows you to perform an even stronger workout!
Skull Labs Skull Crusher Stim Free composition:
- Citrulline malate - a very high dose of citrulline is a guarantee of maximum muscle pump. Its action effectively supports the synthesis of arginine in the body, which translates into an increase in nitric oxide levels. Citrulline also increases endurance, allowing you to perform a much harder workout. A huge muscle pump is an irreplaceable motivation when lifting weights.
- Beta-alanine - a typical endurance ingredient. Allows increased levels of carnosine, which guards long-term muscle performance. beta-alanine contributes to improved recovery. It allows for shorter intervals between series, which in turn increases the intensity of training.
- L-arginine alpha ketoglutarate (A-AKG) - extended duration arginine, or the popular AAKG, perfectly complements the overall Skull Labs Skull Crusher Stim Free pre-workout. AAKG effectively intensifies NO synthesis in the body, dilates blood vessels and allows a greater influx of blood into the muscles. This action, in addition to the sensation of a maximum pump, supports muscle nutrition and improves muscle recovery.
- Betaine - is an ingredient that perfectly supports the work of the circulatory system. Its action not only has health-promoting properties such as lowering homocysteine levels. Betaine also has a no-booster effect, increasing blood flow through the training muscles. Betaine also has the effect of promoting an increase in muscle protein synthesis. Studies show that regular use of betaine builds muscle. In sports supplementation, betaine is often added to pre-workout supplements, where it shows a synergistic effect with keratin, arginine and l-citrulline.
- Taurine - a substance from the anticatabolic and anabolic group. Its action allows the inhibition of the process of muscle tissue breakdown. taurine influences a number of metabolic processes, mainly concerning energy resources. Its use prior to training allows for more efficient use of glucose.
- Glyceryl monostearate - glycerol is an excellent way to increase cell volume. Its action intensifies the increase of water in muscle cells, which indirectly gives a significant muscle pump feeling. However, it is not an increase in nitric oxide synthesis. The action of glycerol is to increase cellular sarcoplasm.
- L-tyrosine - the amino acid l-tyrosine has a metabolism-enhancing effect. In sports supplementation, it is often used on reduction to improve thyroid hormone function. Tyrosine also has a nootropic effect. It helps to increase focus and concentration.
- Choline bitartrate - choline also helps brain tissue to work more efficiently. Choline used to be classified as a B vitamin. Today, this compound has a much broader meaning. Choline allows neurotransmitters to work more efficiently and is also involved in the formation of myelin sheaths.
- Glucuronolactone - in terms of its chemical structure, glucuronolactone belongs to the metabolites of glucose. Its action will primarily support the extraction of energy from nutrients, which translates into better functioning of the body. Glucuronolactone also has antioxidant effects, as well as supporting liver function. Many people indicate that it can contribute to an improved sense of wellbeing, feeling less tired. It adds energy and allows us to do longer work.
- Niacin - classified as a B vitamin and is soluble in water. Niacin influences the formation of many coenzymes and is involved in protein formation. Its effects in sports supplementation are mainly linked to its health-promoting effects on cholesterol levels. Niacin also influences the correct functioning of the metabolism, allows energy to be obtained and improves the functioning of the nervous system. Some sources indicate that niacin may have a nootropic effect.
- Choline alphoscerate (alpha-GPC) - choline alphoscerate is a natural precursor of acetylcholine, which is a neurotransmitter that supports cognitive development and also promotes memory improvement. Choline is a component of cell membranes of neural tissues, including the brain and other nervous tissues. Alpha-GPC is a highly bioavailable form of choline. Alpha-GPC is able to reduce the negative effects of stress and irritability as it stimulates the parasympathetic (calming, sedative) system, increases GABA (inhibitory neurotransmitter) and growth hormone levels.
- Vitamin B6 - a water-soluble vitamin with broad metabolic effects. Vitamin B6 will primarily affect the capacity of the nervous system, which in turn will translate into better muscle performance. Pyridoxine also affects more than 100 different enzymes. Its peri-exercise action helps to improve nutrient utilisation. Among other things, vitamin B6 influences protein synthesis, which promotes the building of muscle mass. It influences the production of haemoglobin, which will promote improved oxygenation of the body and better functioning.
