Key Benefits of Using a Stimulant Free Pre-Workout

Key Benefits of Using a Stimulant Free Pre-Workout

Posted by Medical Research Institute on 9th Sep 2022

When it comes to pre-workout supplements, many people automatically think of formulas that contain caffeine or other stimulants. However, there is another type of pre-workout available that can be just as effective without the use of stimulants. Stimulant-free pre-workouts are designed to enhance pumps, increase power, and improve blood flow to maximize your workout without the use of caffeine or other popular stimulants.

If you are sensitive to stimulants or only want the benefits associated with non-stimulant ingredients, then a stim-free pre-workout is a good option for you. Some of the benefits of using a stim-free pre-workout include bigger pumps, endurance, and muscle growth.

What Is a Stim Free Pre-Workout?

A stim free pre workout is a supplement that does not contain caffeine or other stimulants. Stimulant free pre workouts are ideal for those who prefer pumps while working out or want to avoid the effects of stimulants. High-stimulant pre-workouts activate the central nervous system to increase alertness, intensify focus, and speed up heart rate. Caffeine is the most widely consumed central-nervous-system stimulant. Caffeine increases energy metabolism throughout the brain but decreases at the same time cerebral blood flow, inducing a relative brain hypoperfusion. Caffeine activates noradrenaline neurons and seems to affect the local release of dopamine. Non stim pre workouts provide similar benefits without the side effects of caffeine such as increased heart rate, jitters, anxiety, and crash. If you are looking for a stim free option that will give you energy and pumps during your workout, check out our list of the best stim free pre workouts!


Below are a few questions to help you determine if a non stim pre workout is right for you:

  • Do you prefer pumps more than energy from stimulants?
  • Are you sensitive to stimulants?
  • Do you workout late in the day or evening?

Understanding what the best stim free pre workouts offer will determine if supplementing with it is right for you.


Aside from avoiding some of the effects of stimulant based products than may be undesirable to you, below is a list of benefits that the best stim free pre workouts provide.

  1. No Stimulant Jitters Or Crashes
  2. Increase Endurance & Stamina
  3. Enhance Pumps & Blood Flow
  4. Increase Hydration & Avoid Cramps
  5. Muscle Fullness & Hardness
  6. Increase Power Output
  7. Support For Muscle Growth & Recovery

Key Ingredients for Stim Free Pre-Workouts

Nitric oxide is key to a pump occurring and there are agents that aid in its production. Below is a list of the most powerful NO producing ingredients that effective non stim pump pre workouts should include.

Arginine: Arginine is an amino acid that is a precursor to Nitric Oxide (NO). This means it is necessary to actually create NO. While arginine can help increase NO production, Nitrosigine is a patented complex of silicon and bonded arginine which can increase NO production more than arginine can alone. Here's why Nitrosigine is more effective that just Arginine: Nitrosigine’s patented complex of silicon and bonded arginine is scientifically proven to boost NO life in the body by up to six hours. So far, at least 19 studies support its ability to help improve performance, increase pumps, and reduce muscle damage.

Citrulline Malate: Citrulline Malate is a potent amino acid combo that has been shown in studies to boost endogenous nitric oxide production better than Arginine. It works by first converting into L-arginine once inside the body and then subsequently into nitric oxide. Not only does citrulline malate increase nitric oxide better than arginine, but it also does so without any of the negative side effects (such as gastrointestinal issues) that sometimes occur with supplemental arginine.

Agmatine Sulfate: Agmatine sulfate is another compound that can increase nitric oxide production by inhibiting enzymes that break down nitric oxide. This results in increased levels of circulating nitric oxide, leading to improved blood flow and nutrient delivery as well as reduced inflammation. In addition to its benefits for pumps, agmatine sulfate has also been shown to enhance cognitive function and support healthy insulin levels.

HydroMax: Glycerol is a simple sugar alcohol that has a long history of use in the food industry as a sweetener, thickener, and preservative. In recent years, it has also become popular in sports nutrition for its ability to increase blood flow and hydration. HydroMax is a new form of glycerol that is nearly 6x as concentrated as glycerol monostearate. This makes it one of the most potent forms on the market today. When taken before exercise, it can help to improve blood flow and hydration levels, resulting in better pumps and improved performance. If you're looking for a new way to take your training to the next level, HydroMax is definitely worth considering.
