PreSeries STIM-FREE Review: Make Gains And Increase Performance Without Stims

By Nader Qudimat / Mar 18, 2016

Will the remake be as good as the original?

Cycling and going through days without stimulants is important if you want to keep up the energy and performance in the gym.

PreSeries STIM-FREE by Transparent Labs makes it easier as it's full of ergonomic ingredients that'll not only increase pumps but overall performance as well. It's the perfect pre workout for anyone who wants to make gains without the stims.

Effectiveness

Increases mental function, focus and overall performance without stims.

Ingredients

With fully dosed ergonomic ingredients, you can't go wrong with this one.

Price

It may seem expensive, but you're really getting your dollars worth.

Availability

Not hard to find but still relatively new to the supplement industry.

We like

  • Full dosage of citrulline malate (6g)
  • Helps increase strength and muscle size
  • Testosterone support
  • BCAA's and a few others to decrease soreness and increase recovery​​​​
  • Research backed ingredients (and fully disclosed)
  • Increases mind to muscle connection

We Don't Like

  • Foamy
  • Fillers are not disclosed (Suppose to be 100% transparent)

Transparent Labs is a pretty fresh company that hasn't been around for too long.

But one look at their supplements and you'll understand why they are beginning to be one of the most popular choices.

​​​​STIM-FREE is no different.

We recently reviewed their PreSeries Bulk, which you can see here, but this is basically the stim-free version.

Now it may seem expensive at first glance, and rightfully you've got doubts.

But compare it to any of the many pre workouts, and you'll see why it's probably going to be one of the most preferred supps out there.

For one it's got a 21 gram scoop filled 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. 

What is PreSeries STIM-FREE?

Everyone knows that you can't take stimulant-based pre workouts on a daily basis without facing some kind of consequences.

You'll feel drained, your sleep quality will drain, and you just won't be as motivated to workout as you once were.

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.

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

What makes PreSeries STIM-FREE Special?

Compared to other stim-free blends, this one is a bit different:

  • 23.4 grams of active ingredients
  • Excellent Dosages of Citrulline Malate, Beta Alanine, and BCAA's
  • Testosterone Support (with vitamin D, Mucuna Pruriens, and Zinc)
  • 3g of creatine HCl
  • Nitric Oxide Boosters
  • Natural sweeteners (Stevia) and coloring

All this comes at a price though and since it is super packed with beneficial, ergonomic ingredients, it's a bit expensive.

It's priced at 49$ but if you sign up to their email newsletter, you can knock off 10%.

If you're looking for the strongest pre workouts or if you're not sure and you want to go through our buying guide for pre workouts)

Looks like we're ready for some gains...

The size of the bottle is about 4 times bigger than a 60 serving of C4 but yet it's around the same price.

So before you jump into any pre workout, check out the ingredients and make sure you understand what you're getting and that you're not getting a pre workout that has servings filled with pixie dust dosed stuff!

PreSeries STIM-FREE Ingredients 

preseries stimfree

While Transparent Labs promises to be super transparent, they do not disclose their filler amounts like NutraBio would.

But they do disclose everything else so that's alright.

The scoops are almost as big as protein scoops, so you know you're getting everything you need just before a hard workout.

It's got everything from nitric oxide (6 grams of citrulline malate), testosterone support to BCAA's and betaine anhydrous for strength and muscle gains.

And it's stim-free, so there are no stimulants, or you can add your own stims to it.

But unlike PreSeries Bulk, it has 3g of creatine, and a 2.5g of betaine anhydrous instead of 4.

We got a guide if you'd like some help finding the perfect pre workout for yourself. 

Same applies for pre workouts 😉

Testosterone Support

  • Vitamin D3 (3,000IU)
  • Zinc (30mg)
  • Boron Citrate (5mg)
  • Mucuna Pruriens (70mg)

Most pre workouts have vitamin B complexes, C, and maybe some electrolytes.

But only a very few actually have testosterone supporting vitamins like what you see here.

Vitamin D3 (3,000IU)

Vitamin D is one of the most common vitamins that people are deficient with. (It's the sunlight vitamin that most of us miss out on)

It's important for bone health, maintaining the immune system, and most importantly, it helps increase testosterone levels.

It's important for bone health, maintaining the immune system, and most importantly, it helps increase testosterone levels.

With vitamin D3 being the most bioavailble form of vitamin D, you'll want to have the D3 version when supplementing.

Zinc (30mg)

Zinc may as well maybe one of your favorite ingredients. If you exercise intensely, you're most likely to be low on this.

With high exertion (both in the gym, and in life; stress), your testosterone levels naturally decrease but research has found that supplementing with zinc prevents that, as it helps promote higher free testosterone levels and not to mention improved endurance and thyroid levels.

Zinc is one of the essential minerals that is involved with maintaining many of the normal body functions.

If you're serious about making gains or just being healthy, you'll want to have this in your supplement arsenal.

Maybe so...

Boron (5mg)

Another essential mineral that you should be using. It's been shown to maintain and improve bone health.

An interesting find on this mineral in studies, is that it tends to decrease SHBG (sex-hormone-binding globulin), a protein that binds to testosterone in the blood.

Decreasing SHBG means that you can have more testosterone free and help you make more gains. It's basically like an anti-estrogen which is perfect in any testosterone booster.

Mucuna Pruriens (70mg)

Both a testosterone booster and a dopamine enhancer, mucuna pruriens is known for it's stimulating effects on testosterone, and it indirectly increases GH production.

With it in PreSeries STIM-FREE, you'll be more motivated as it also increases dopamine / pleasure.

But most importantly, it helps with testosteron​​​​e production and decreases stress.

The recommended dosage for Mucuna however, is 100mg 3 times a day, or at least a bit more than 70mg.

So while this seems low, remember that there's other testosterone increasing ingredients in here.

It's one of those ingredients that's nice to have but it won't be missed if it wasn't included.

Citrulline Malate (6g)

The everlasting ingredient of the bunch.

Citrulline Malate is awesome for endurance, pumps and delaying fatigue.

It's the super version of arginine as it's more bioavailable and much more effective.

Citrulline is the amazing ergonomic ingredient that can increase overall performance.

The increase in nitric oxide will lead to more endurance, increased overall performance and strength.

Like beta-alanine, it buffers ammonia and lactic acid, leading to greater output in performance and making you last through an intense workout more efficiently.

It has the perfect dosage as it's recommended to have anywhere from 6-8 grams of citrulline malate pre workout.

If you're looking for pure citrulline rather than the malate version, check out Pre-Kaged.

Beta Alanine (4g)

After learning what citrulline malate does (buffers lactic acid), including beta-alanine just further makes this pre workout nearly limitless for increasing performance and gains.

What beta-alanine does is that it binds to histidine and turns into carnosine, which is super effective for buffering lactic acid.

With 4 grams per serving, you'll undoubtedly experience a tingling sensation (some people naturally don't) but it's totally safe and temporary.

Rest assured though, you're getting the full clinical dosage. There are no pixie dust dosages here.

BCAAs (2g at 2:1:1)

Training without BCAA's is like leaving a pile of cash on the table hoping no one would steal it.

BCAA's is the building block of muscle protein synthesis and it can make the biggest difference in the world.

Not only can it speed up the fat loss process but it can help maintain and promote muscle synthesis.

It basically keeps you in a prime anabolic state.

Since it stimulates protein synthesis, it'll also increase recovery, decrease soreness and fight off catabolism so you keep growing and maintaining your gains.

(See our BCAA buying guide if you're looking for BCAA supplements)

Betaine Anhydrous (2.5g, BetaPure™)

Betaine Anhydrous... Ain't it pretty?

This here is another "household" ingredient that is a powerhouse for more gains.

Made popular in 2015, betaine has been shown to decrease muscle soreness, increase muscle, endurance and overall power.

It works perfectly with creatine, though there is no creatine present in this formula (there is if you go for the Stim-Free version).

The studied and proven dose is at 2.5g, so you're getting the full dosage here.

Taurine (1.3g)

Mainly a muscle volumizer (and a mental focus enhancer), taurine works to pull in more water and nutrients to the muscle.

It's not so much of a nitric oxide ingredient as it is a water filler.

It's like glycerol monosterate but it's a conditionally essential amino acid so your body does need it (it's present mainly in the heart, brain and skeletal muscle).

When taken alongside BCAA's, citrulline and the other soreness "fighters" here, it works much better in making you feel more recovered and fresh. 

N-Acetyl L-Tyrosine (600mg)

Like citrulline is to arginine, N-Acetyl L-Tyrosine is much more bioavailable than tyrosine.

It's used to enhance focus and promotes the production of dopamine to help you feeling good.

It decreases stress and anxiety, making you feel good during your workouts (no not as good as Driven Sports Craze, but you can check out our strongest pre workouts if that's what you want)

Most pre workout cheap out and only include half the dosage present here, so you're definitely getting what you pay for. 

Choline Bitartrate (500mg)

Known more of a nootropic than anything else, choline helps you feel more connected to your workouts, increasing more mental focus and concentration.

While choline bitartrate is the cheaper version of choline, it is still quite effective at 500mg and you'll definitely benefit from it here.

Jam packed scoops of active ingredients. Sorta like this...

L-Norvaline (60mg)

In case you've forgotten, we've got some massive dosages for muscle pumps and gains so far and having l-norvaline here is just going beyond all of our exceptions.

Derived from the amino acid l-valine, it helps improve blood flow (indirectly increases cardiovascular abilities).

It's a luxury to have when stacked with other nitric oxide boosters as it further enhances the benefits.

It stops nitric oxide (Arginase) from breaking down which means more and longer pumps, better nutrient delivery and increased blood flow.

BioPerine® (5mg)

BioPerine is the black pepper extract of this formula.

You've probably seen in more and more pre workouts these days and it's there for good reason.

It's to improve the overall digestion and bioavailability of all the ingredients in this formula.

It prevents the breakdown of the ingredients and helps maximize their benefits.

With the number of ingredients here and their benefits, BioPerine is here to make sure you make the most out of them.

  Features:

  • 30 full servings
  • Citrulline Malate (6g)
  • Combination of nitric oxide boosters
  • BCAA's and 2.5g of Betaine Anhydrous
  • 23 grams of active ingredients in each serving

Flavors Available

Blue Raspberry

Only one flavor, Blue Raspberry.

You shouldn't be disappointed, it's actually a good thing.

You won't be so obsessed with getting the best flavor. 

You're here to make gains, not to taste wine, right?
