Stimulant-free pre-workouts, do you use them?

Although there are many products for that critical moment, stimulant-free pre-workout supplements also help maximize performance.

These stimulant-free pre-workout supplements will improve pumps, increase power, and enhance blood flow during every repetition, but the difference is that they contain no caffeine or other popular stimulants used in conventional products.

A non-stimulant supplement is a good option if you are sensitive to stimulants or simply want to obtain the benefits associated with non-stimulant ingredients such as those mentioned above. And although these products taken before training are almost synonymous with ingredients such as yohimbine, synephrine, or caffeine, many competitive bodybuilders use them.

Why use pre-workout supplements

They work in several ways to ensure that the hard work you do in the gym is supported by key nutrients.

• The first thing they do is generally increase energy through caffeine, although others also contain creatine and citrulline malate, which help build strength and muscle.
• Next, they increase concentration and mental focus, which is essential for neuromuscular connection from the first repetition, including the warm-up beforehand.
• These ingredients are also available or used for other purposes, such as burning body fat, whose thermogenic properties are excellent, especially during a cutting phase.

However, when it comes to supplements, proprietary blends are also used, even though the problem may lie with the label.

The critical problem may be the lack of information about each ingredient.

In certain cases, this may work for both well-known products and, in the case of less reliable brands, unknown ones.

Obviously, at MASmusculo we avoid marketing supplements with dangerous ingredients, whether because of their addictive potential or side effects such as hypertension and mood changes, as well as synthetic ingredients that do not even appear in stimulant-free pre-workout supplements.

How stimulants work

Here, we discuss three examples of stimulant ingredients;

Caffeine is the most widely consumed central nervous system stimulant because it increases energy metabolism throughout the brain while simultaneously decreasing cerebral blood flow, inducing relative cerebral hypoperfusion.

• This compound, which is not present in stimulant-free pre-workout supplements, activates norepinephrine neurons and appears to affect local dopamine release.
• Many of caffeine’s alertness effects may be related to the action of methylxanthine on serotonergic neurons [1].

Another compound is yohimbine, which is made from herbs; it is an ingredient that has been widely used in African medicine, especially for sexual performance.

• Many believe that yohimbine works by blocking receptors in the body called alpha-2 adrenergic receptors [2].
• These receptors play an important role in inhibiting erections, but they can also promote the release of nitric oxide. This could cause the blood vessels to dilate and increase blood flow to the muscles.

Brands also use proprietary compounds to increase strength and performance, stimulating the nervous system so that adrenaline rises during hard workouts.

• These stimulants activate the central nervous system to increase alertness, intensify focus, and accelerate the heart rate.
• In this way, they increase energy and the mind-muscle connection, benefiting the athlete with every repetition of every set while also reducing fatigue.

There is no doubt that this type of supplement is great; however, its ingredients may irritate you or, for example, keep you awake.

Stimulant-free pre-workouts: what are they?

The phrase “stimulant-free” is clear, but these products are also formulated to achieve spectacular pumps and increase blood flow, delivering the explosiveness you need as well as transporting nutrients to your muscles; therefore, they may also aid recovery.

The basic non-stimulant ingredients found in several stimulant-free pre-workout products include agmatine sulfate, beta-alanine, creatine, and citrulline malate, among others, which we will examine later based on their properties.

A key point is the use of nitric oxide (NO2), which is not a stimulant; these products help with vascularization and promote a hyper-pump.

• They do this by opening the blood vessels and expanding the nutrient-delivery systems to the muscles while you train.
• This means that the nutrients that help nourish and grow your muscles are delivered more quickly and efficiently.

Regarding stimulant-free pre-workouts, your muscles need blood and oxygen to transport these essential nutrients so they can function, grow, and recover effectively.

When vascularity expands, amino acids and nutrients can be transported to the muscle more efficiently.

Now, the reason a pump is effective is that increased blood flow causes hydration to stimulate protein synthesis rather than its breakdown, thereby helping create the perfect anabolic environment for muscle hypertrophy.

Stimulant-free pre-workouts: what are their benefits?

First of all, you should ask yourself a few questions to determine whether a stimulant-free pre-workout is right for you:

• Do you prefer pumps over the energy from stimulants?
• Are you sensitive to stimulants?
• Do you exercise at the end of the day or at night?

Understanding what these supplements offer will determine whether or not you should use them in certain circumstances. In any case, you should know their benefits to compare your pre-workouts:

• They increase endurance and reduce fatigue.
• They improve pumps and blood flow.
• They promote hydration and prevent cramps.
• They provide muscle fullness and hardness.
• They increase power output

Without a doubt, they can be great for promoting muscle growth, and this is where your mind generally starts to get confused, right?

It is a matter of trying them and comparing them based on your well-being both at the gym and at home, while sleeping and during your daily activities.

Stimulant-free pre-workouts: key ingredients

Nitric oxide is key to the muscle pump, so we will analyze which ones help produce it, even if it is repetitive.

Arginine is the amino acid precursor to nitric oxide (NO), par excellence.

Meanwhile, nitrosigine, a patented complex of silicon and bonded arginine, may be more effective in all these respects.

• This complex has been scientifically shown to increase the lifespan of NO in the body by up to six hours, which boosts performance, increases blood flow, and improves concentration and energy [3].

L-citrulline derived from arginine; is it understood?

• As arginine is converted into nitric oxide, L-citrulline is also produced; therefore, they work synergistically to improve blood flow.
• The point is that when arginine is taken directly, it is degraded in the liver, leaving little to be absorbed by the gastrointestinal tract.
• Citrulline can bypass the liver and be converted into arginine in the gastrointestinal tract, allowing your body to use more arginine.

Agmatine sulfate, for its part, prevents the breakdown of NO so that you can improve your endurance during training.

• Agmatine blocks NOS synthase, which breaks down (NO).
• This means that when your body produces more nitric oxide, it will help prolong the pumps and the benefits associated with nitric oxide.

High-concentration glycerol powder ingredients are also used, recognized for their ability to induce a pump. Because it is a water-attracting molecule, it can carry water to your muscles and fill muscle cells.

The same applies to L-ornithine, an amino acid that widens blood vessels and plays a role in detoxification processes.

This allows you to have more energy and a better pump.

Stimulant-free pre-workouts: core ingredients

Obviously, there are stimulant-free pre-workout products that have been used for a long time and do not contain some of the compounds analyzed above, and that are popular for their effectiveness.

Among the core ingredients, we consider:

• Creatine: a well-tested strength precursor and muscle builder; remember that it also supports mental function.
• Citrulline malate: another muscle builder that also increases aerobic performance and muscular endurance.
• Beta-alanine: it helps increase endurance during intense exercise, promotes protein synthesis, and increases lean muscle mass.
• Anhydrous betaine: it is effective for building muscle mass and strength, but it also reduces fatigue in most cases.
• Bioperine: this compound helps your body absorb more ingredients from stimulant-free pre-workout supplements instead of simply passing them through your system.

To conclude, let's talk about the well-known BCAA—branched-chain amino acids that help you not only reverse fatigue through the tryptophan pathway, but also recover faster or increase production of the HGH growth hormone from the very first set.

And how does tyrosine work?

Since reduced dopamine levels within the central nervous system decrease motivation and performance, leading to fatigue, there are new ways to increase dopamine production, thereby improving performance.

• It was recently demonstrated that consuming the dopamine precursor tyrosine provides this benefit, confirming that it influences the ability to tolerate prolonged exercise.
• Combining tyrosine with folic acid can further increase dopamine by raising levels of tetrahydrobiopterin (BH4), a cofactor of tyrosine hydroxylase that facilitates the conversion of tyrosine into L-dopa.

Conclusions

Adrenaline activates several biochemical pathways that increase glucose and fatty acid levels in the blood, providing energy to muscle cells.

Some stimulant-free pre-workout products increase adrenaline and dopamine, providing an even more robust neurochemical environment in the brain, which enhances training performance.

The various basic and key ingredients work synergistically to stimulate the sympathetic nervous system, resulting in the release of adrenaline.

This is generally achieved through improved gastrointestinal absorption and systematic nutrient utilization.

Likewise, these compounds work to maintain cell volume and fluid balance in stressful situations such as dehydration.

Many of these stimulant-free compounds have also proven effective at increasing muscle protein synthesis during training, as well as influencing protein breakdown.

Obviously, the nitric oxide (NO) signaling molecule also comes into play, improving performance by increasing blood flow caused by enhanced vasodilation.

• Increased blood flow due to vasodilation provides more essential nutrients and oxygen to working muscles while simultaneously removing metabolic waste.
• These compounds can vigorously increase endogenous arginine levels and boost NO production, helping to achieve spectacular pumps.

Likewise, ammonia accumulation reduces energy production while increasing lactic acid production.

This has a negative influence on exercise performance.

Non-stimulant ingredients can also reduce ammonia accumulation, thereby reducing lactic acid accumulation.

To conclude, we have compiled it into a video made at MASmusculo about peri-workout drinks, which you will surely be pleased to share.
