Transparent Labs PreSeries Lean Pre Workout Review


Transparent labs lean pre workoutHow can you not love this pre-workout from Transparent Labs?

Transparent Labs PreSeries Lean Pre Workout gave me an energy boost like you will not believe!

I want to start off by giving a huge thank you to Matt from Transparent Labs for sending me a bottle of the PreSeries Lean Pre Workout to Review.

I’ve been involved in the supplement industry for a long time and have tried thousands of different pre-workouts. To be honest, only a few out of all the different supplements I have tried actually did what they claimed to do.

What I really like about Transparent Labs is just how “Transparent” they really are.

On Transparent Labs PreSeries Lean Pre Workout, every single ingredient is listed directly and they show you exactly how much of each ingredient is in this product. Transparent Labs actually does this with all of their products.

This is why Transparent Labs is doing so well and making a major impact in the supplement industry.

Who else is sick of proprietary blends and shady supplement companies?

Transparent Labs is owned and operated by good people who actually want to help you with your goals. Not many other companies list off every single ingredient on their product because they know if they do, no one would buy them.

No bunk fillers and never will you see a proprietary blend with a Transparent Labs Product.

Am I a little biased….Sure I am. I have a great relationship with one of the co-owners but this relationship developed after the fact.

Let me dive in and give you a brutally honest review of Transparent Labs PreSeries Lean Pre Workout.

PreSeries Lean Pre Workout Review

Let’s start from the top…

I didn’t order this product directly from their website because I was in contact with them. They did send me a bottle of the PreSeries Lean for no cost but it was shipped like any other order processed on their website.

I live in Chicago and the company is based somewhere out of California. Transparent Labs shipped the product through USPS and it arrived within two days. The packaging was tight and compact keeping the pre-workout from getting damaged during shipping.

My first impression from picking up the bottle of PreSeries Lean was great. The bottle is much bigger than your typical pre workout container and was filled pretty much to the top.

I’m so tired of buying a 30 serving pre workout that has a tiny scooper and is filled with air. The Transparent Labs PreSeries Lean Pre Workout was filled to the brim!

The bottle was actually heavy…

PreSeries Lean Taste and Flavor

Now Transparent Labs PreSeries Lean is offered in a Blue Raspberry Flavor and I believe that is the only current flavor offered at this point in time.

What I noticed, when I first opened the bottle, was an initial smell which resembled a vanilla protein powder smell. I had my girlfriend smell it too and she disagreed with me.


I filled my shaker cup with about 24 ounces of water, I basically always max it out to the top because I like my pre workout watered down, and then turned on my turbo blender mixer. The mixability was great, within seconds the whole thing was mixed very well and I noticed very little debris on the bottom.

One thing I want to mention is the color of this pre workout.

Transparent Labs PreSeries Lean features zero colored dyes which is unlike most other popular pre workout supplements. When you mix this pre workout, you are not going to notice much of a color difference.

It’s almost like a cloudy, water color and not a deep rich blue that you might be use to with other Blue Raspberry Flavored Supplements.

Now let’s talk about the taste…

To be perfectly honest, it’s not the best tasting pre workout I have ever had. You definitely can taste the Blue Raspberry Flavor however it’s not very rich in flavor like an Amino Energy by Optimum Nutrition for instance.

Since there are absolutely no fillers or harmful additives, the flavor isn’t going to be as strong as supplements that use artificial flavoring.

Don’t get me wrong, I have had way worst tasting pre workouts. This is definitely not that bad.

PreSeries Lean Ingredient Profile

In my opinion, Transparent Labs PreSeries Lean Pre Workout has an incredible ingredient profile. The ingredients listed are perfect for weight loss and contain great stimulants.

Check out the ingredients in this pre-workout formula…

  • Citrulline Malate 2:1 – 6,000 mg
  • BCAA 2:1:1 – 2,000 mg
  • Beta-Alanine – 1,500 mg
  • Betaine HCL – 1,000 mg

  • Synephrine HCL – 50 mg
  • Hordenine – 25 mg
  • BioPerine – 5 mg
  • Chromium Picolinate – 200 mcg
  • Thyroid Support – 156.5 mg

As you can see above, every single one of these ingredients featured in Lean are written out and properly dosed.

PreSeries Lean Energy & Effectiveness


I decided to stop taking any form of stimulants, even just caffeine, before trying out Transparent Labs PreSeries Lean Pre Workout. I wanted to really get a feel for this product and see how great these ingredients stack up.

I typically work long hours and will occasionally drink a pre-workout supplement in place of coffee in the morning to get going. My first time trying PreSeries Lean, I did just that.

I was extremely exhausted and it was early in the morning so I filled my blender cup to the top with water and then did one scoop of the Lean Pre-Workout. I decided to just chug the entire thing all at once and waited to see what would happen.

I would say within 15 minutes I started feeling an energy boost.

The first thing I noticed was the tingling feeling of the Beta-Alanine on my arms and other parts of my body. Some people don’t like that feeling but I love it. It makes me feel like I’m in the zone.

Fast forward to 5 hours later and I was still feeling energized. Time flew by while I was working and I accomplished so many things throughout the day.

The energy is a constant, feel good energy that doesn’t give you a crash later on.

Transparent Labs PreSeries Lean has 180 mg of Caffeine which is actually much less then you will see in most modern pre workout supplements today.

However all the ingredients combined gave me a wonderful energy boost and I honestly can say I felt good the entire day.

Every since I received this bottle of Lean, I have been taking it daily. It’s great before my lifting days at the gym and also great just to have energy throughout the day.

I highly recommend Transparent Labs PreSeries Lean and I can’t wait to see what else this company comes out with in the future.
