Going caffeine free doesn't mean you need to avoid pre workouts. 

PreSeries STIM-FREE enhances workout performance without using stimulants. 

It's full of ergogenic ingredients that'll not only increase pumps but overall performance as well.

STIM-FREE the perfect pre workout for anyone who wants to make gains and it can increase strength and elevate mood without needing stims.

Stim-Free is completely free of caffeine and stimulants.

Using this pre workout will make cycling off stimulants effortless.

Or it can be used for evening workouts.

You'll great pumps, enhanced focus and improved endurance all while not using a single milligram of stimulants.

For one reason or another, whether you are sensitive to caffeine, or you simply have gone too long without cycling it, Stim-Free is the perfect choice.

The problem with heavy-stimulants is that you're burrowing energy from your future self, hence why you may crash, and have withdrawals that may last for days.

The other pre workouts by Transparent Labs include Lean, a fat burning pre workout, Bulk, a pre workout for gaining muscle, and Stim-Free, basically the same as Bulk but without the stimulants. 

Transparent Labs is a Utah-based company that grew to a top tier company that produces future-proof supplements.

Stim-free is no different.

This pre workout is the stim-free version of Bulk and contains all the good stuff without the caffeine.

What makes Stim-Free special isn’t the fact that it’s packed and fully disclosed with performance boosters, it’s that it’s been one of the best caffeine free pre workouts for a few years straight.

Without using any trendy or hyped up ingredients, Transparent Labs is able to keep this pre workout in the spotlight for a few years now.

All of their pre workouts are highly rated and praised.

It features a 21 gram scoop packed with performance enhancing ingredients.

And another is that they not only include a testosterone support blend, but also everything is disclosed so you know what you're getting.

I've used Stim-Free quite a few times now and typically I'd take it first thing in the morning. 

First thing that I've noticed is that the scoop is quite big. 

It's like a protein scoop, and it's no wonder seeing how large the servings are. 

Every serving is packed with nearly 23g and it's a completely stimulant free pre workout. 

This means it can be taken anytime and it won't disturb sleep. 

The ingredients are helpful for strength and muscle building as I noticed it has everything needed including beta alanine, betaine and elevATP. 

All of these ingredients have been shown to support muscle and strength in one way or another. 

Of course since it doesn't have stimulants, it wouldn't be fair to rate it's energy but it does have tyrosine and choline, which both support mental function. 

And huperzine A is also included, an ingredient that'll help prolong the effects of choline. 

And that it did. 

I was focused during my workout and long after as these nootropic ingredients can help with mental functions for hours at a time. 

I barely felt the tingles as well from the 4g of beta alanine but I am used to taking beta alanine so my body is probably saturated with it. 

And if you're not, don't worry, it'll take a week or two for the harmless tingles to subside, if it's something you're concerned about. 

PreSeries STIM-FREE is the exact same as PreSeries Bulk but without the stimulants.

It contains everything needed to make muscle gains and increase performance in the gym but just without caffeine.

This doesn't mean you can't add in your own caffeine source.

This means you can still drink your coffee along with your pre workout or that you can still workout with a pre workout that doesn't have any caffeine.

There are 2 reasons why you'd want to go stimulant-free…

One is that you want to use your own stimulants, maybe caffeine with something else or maybe you're on something like Adderall and can't use any sources of caffeine with it.

You can't take stimulant-based pre workouts on a daily basis without facing some kind of consequences.
The more often you take pre workouts, the more you'll develop tolerance and dependency to use them.

You'll eventually feel drained when you're not using them, your sleep quality will suffer, and you just won't be as motivated to workout as you once were without stimulants.

But if you cycle and control your stim intake, maybe even cut it all out for a short period of time, you'll get hit with the stimulants like the very first time you had them or at least close to it.

And you'll just feel overall refreshed and ready to pump it up at the gym.

Compared to other stim-free pre workouts, this one is a bit different.

Transparent Labs has formulated this pre workout to contain ingredients that increases power, improves recovery, boosts endurance, nitric oxide enhancement and testosterone support.

While most stimulant-free pre workout have a simple formula of mainly citrulline and glycerol, Stim-Free has gone above and beyond by covering all aspects of training.

This is an all in one pre workout, no matter if you’re doing cardio, cross fit or bodybuilding, every ingredient is going to help boost nearly every aspect of training. 

Creatine and betaine is at the top of the formula as they both are dosed the highest, and they are heavily researched and backed with studies proving their efficacy.

For endurance and power, beta-alanine is included, and you'll have maximum mental functions thanks to the big doses of nootropics.

Anyone who doesn’t want stimulants in their pre workouts will enjoy Stim-Free.

Such a pre workout is very flexible, it can be taken at 12 am and you’d still be able to fall asleep 10 minutes later.

But once you start training, you’ll feel focused and enhanced as this formula is packed with 10 ingredients that are all shown to work well.

As solid as this formula is, there’s not going to be any need to reformulate this pre workout because the ingredients are future-proof and have years (some have decades!) of research and use behind them.

Here's some advantages to using Stim-Free:

Cycling Off Stimulants

Since Stim-Free is completely stimulant free, but yet contains everything else that is needed to increase power, strength, performance and endurance, it is the perfect choice.

Caffeine / Stimulant Sensitivity

If you can’t stand stimulants or are super sensitive to stimulants, Stim-Free is perfect.

Women or Men

The testosterone blend here is only made out of minerals that women should be getting from their diet anyway so there isn’t anything here that makes it only exclusive for men.

Cardio / Endurance Training

Very few pre workouts can be recommended for cardio-based training since most of them contain a high amount of stimulants that would only do more harm than good.

Stim-Free is perfect for cardio training.

Normally, pre workouts shouldn’t be taken late in the afternoon and should only be used for a short period of time before cycling off.

This is because of the stimulants that are in pre workouts.

Stim-Free is different.

Since it has no stimulants, you guessed it, it can be taken at night, even before you sleep but you might be bothered by the tingles due to the beta alanine.

The nice thing with stimulant-free pre workouts, they can be taken as late or as early, and they still have the same effect.

With Stim-Free, the more it’s taken, the more it can saturate into your muscles.

Ingredients like beta alanine and creatine get better with more usage.

All the ingredients here get better with each use.

Because of this, there’s no reason to cycle off and it can even be taken for years.

If you’re a healthy individual and have taken the “ok” from your doctor on taking supplements with these ingredients, then you’re good to go.

And since the ingredients here are going to optimize and tune your body / muscles, from the testosterone support to the muscle building ingredients, Stim-Free can be taken many hours before your workout.

If you’ve made it this far down, then you know this pre workout is the best caffeine free choice.

Stim-Free wouldn’t be complete without some nitric oxide boosters.

And Transparent Labs has done it right with a decent dose of 6g.

Dosages can go as high as 8g, but 6g is the very minimum that we need to see to be happy.

This pump-inducing ingredient is the ultimate version of arginine as it’s much more bioavailable.

It buffers ammonia and lactic acid, letting you have more power in the tank to push through an intense workout while delaying fatigue.

By increasing nitric oxide, it will lead to more strength and power and improving overall athletic performance.

This powerful amino acid, beta alanine, is well known for increasing strength and power output.

Like citrulline, it works by removing and reducing lactic acid in the muscles.

The lactic acid builds up with muscle exertion and physical activity.

By reducing this acid, you'll be able to push harder for a longer period of time before feeling fatigued and you'll be able to lift more.

Since it is an intracellular buffer, it gets better overtime and it tends to saturate the muscles with each use.

The hefty 4g dosage will definitely lead to massive tingles, especially if you’re not used to this ingredient.

Don’t worry though, the tingles are completely harmless and they’ll reduce overtime once you're saturated with beta alanine.

BCAA’s is often used to help prevent muscle loss and improve anabolism.

It’s the building block of muscle protein synthesis.

By stimulating protein synthesis, it can decrease muscle soreness, help with recovery and increase muscle growth.

This means even if you’re on a strict diet with caloric restrictions, BCAA’s here will help you maintain the lean mass you’ve worked hard to get.

Betaine is a powerhouse ingredient that has been shown in multiple studies to increase muscle protein synthesis, strength and stamina.

It works in synergy with creatine they both enhances the body’s production of ATP.

The clinical dose here makes Stim-Free a powerful pre workout for strength and mass gains.

Taurine is a great muscle volumizers that’s highly underrated for its many benefits.

Like glycerol monostearate, it increases muscle size by increasing water in muscles, leading to more “wet pumps”.

It doesn’t make it any less important.

Taurine is found in the heart, brain and skeletal muscle, making it a conditionally essential amino acid.

When it’s combined with creatine, BCAA’s and betaine, it can increase recovery and decrease muscle soreness.

Tyrosine is an interesting ingredient and it's one of our favorite non-stimulant energizers. 

It’s mainly used for focus enhancement and improves dopamine production.

Not only can it decrease anxiety and stress, but it acts like caffeine as it can increase alertness and energy.

Choline Bitartrate is a nootropic that’s often combined with other focus enhancers, like caffeine and huperzine A.

Here it’s used to help enhance the mind to muscle connection, improving overall mental focus and concentration.

The 500mg dose is quite enough, although it’s a cheaper version of choline, you’ll certainly feel it’s benefits.

When it comes to strength boosting ingredients, you can consider ElevATP to be one of the best for this category.

This is one of the newer muscle building compounds to hit the market.

ElevATP is a combination of ancient peat and a proprietary apple extract. 

It can increase ATP production and power as it shows it can give significant gains in trained men for strength, power and performance. 

To help enhance bioavailability and absorption of all the ingredients here, BioPerine is included.

It can help improve digestion of other ingredients and thus maximizing their benefits.

This is definitely a must have in a monster pre workout like PreSeries Stim-Free.

A pre workout like this one can’t be cheap but it isn’t more expensive than all the other options out there.

It’s priced at $49.99, but you can knock off $5 with this coupon code FITFREK

You may find cheaper pre workouts but look at their serving sizes and ingredients.

Most of them will either require double serving to get the most out of the ingredients, or won’t even have close to what a pre workout like Stim-Free would have.

If you buy more than one bottle, that’s where the savings really start.
