There are plenty of ingredients out there that can increase pumps, focus, and exercise capacity.

In this article, we’re going to show you the best stimulant free products to boost your workouts.

A caffeine-free pre-workout is a pre-workout supplement that does not contain caffeine or other forms of stimulants.

It’s also called a stim-free pre workout by many. 

These types of supplements are popular because they’re entirely free of any kind of stimulant.

Take caffeine, for example. Caffeine is a central nervous system stimulant. When ingested, it boosts alertness and energy.

Therefore, it’s found in a lot of bodybuilding supplements such as PWO’s and fat burners.

Best Stim Free Pre Workout Ingredients

What makes the products in our top 3 so unique is the set of ingredients behind them.

Especially Pump Serum was formulated well; it is on a whole different level compared to the rest.

The ingredients in a product are the deciding factor in whether you’ll have a good workout.

We’ve done a lot of testing and researching on caffeine free pre workout supplements.

This means we’ve done our homework when it comes to the ingredients they contain. Let’s take a look at a few of the most promising ingredients.

Glycerpump is a patented ingredient form of glycerol powder. It’s a naturally occurring sugar alcohol that is responsible for accumulating body fluids.

This ingredient is often used in caffein free pre workout supplements because it helps hydrate the muscle, causing a greater pump.

It has also shown to improve aerobic and anaerobic performance in athletes.

Another popular ingredient is Beet Root Extract (Beta vulgaris rubra). Besides being rich in antioxidants, Beet Root Extract is an excellent compound for boosting nitric oxide.

When nitric oxide (NO) is increased, more blood will get pushed into your muscles. Once this happens, you will experience a more significant muscle pump when working out.

Therefore, it is one of the key ingredients found in many stim free pre workouts.

L-Tyrosine is often added to supplements to function as a nootropic. It is said to boost alertness and focus. It’s great to get in the zone during a workout.

Agmatine Sulfate (4-aminobutylguanidine) is an amino acid with a wide variety of potential benefits.

Many users claim it to be great at increasing pumps, exercise performance, and focus.

Unfortunately, the clinical data on Agmatine Sulfate is limited.

Of course, these are just a few examples, and there are plenty of stimulant-free ingredients that work very well.

We advise buying one of the above products if you want to get in a proper workout.

If you decide to go with a different product, always make sure to check the ingredients.

We’ve also reviewd other products that do contain stimulants, check out Dark Energy and Bucked Up Review.

Should You Use Pre Workout Without Caffeine?

If you want to maximize your workout intensity and performance without wanting to use stimulants, you can use a pre workout without caffeine.

By doing so, you can still get that extra boost during a training session. In my opinion, the products work just as well.

They contain ingredients that have been proven to boost nitric oxide, focus, and energy. But, they won’t cause anxiety or insomnia like high stimulant pre workout supplements might do.

With a good product like Pump Serum, you’ll experience better muscle pumps, focus, and overall power.

We advise taking it about 20 to 30 minutes before hitting the gym so that the ingredients have plenty of time to kick in.
