How and When Do I Take It?

As per the manufacturer’s recommendations you are to take one scoop of Transparent Labs Stim-Free Pre-Workout in 6 – 8 oz of water approximately 20 – 30 minutes prior to training.

When you first use this product you are advised to begin with a half serving so that you can test your tolerance to ingredients like Beta-Alanine; once you are satisfied you tolerate the ingredients well you can graduate to a full dose for increased intensity.

Benefits of PreSeries Stim-Free Pre-Workout

The most immediate benefit of a product like Transparent Labs Stim-Free Pre-Workout is that it contains absolutely no stimulants.

This makes it an ideal pre-workout supplement for any of you who cannot tolerate caffeine well or otherwise looking to minimize your consumption of stimulants on a daily basis.

Aside from this, you will notice that there are 6 g of BCAA in every serving, giving your body exactly what it needs to kick start muscle protein synthesis and assist in the recovery process before you even train.

When you are training hard on a consistent basis you will be breaking down your muscle tissues, which can be incredibly catabolic and lead to muscle wasting if the rest of your diet and supplementation are not in check.

By stimulating muscle protein synthesis with BCAA you will be minimizing the catabolic effects associated with this type of intense training, helping you to make progress in both size and strength gains more rapidly than ever before.

Creatine HCl is another fantastic ingredient that you will find in Transparent Labs Stim-Free Pre-Workout.

Creatine helps to increase intracellular concentrations of what is known as adenosine triphosphate or ATP.

ATP is a naturally occurring substance within the human body that acts as a kind of medium or currency for the exchange of energy between cells. Simply put, more ATP in your body means that more energy will be available, promoting greater strength, power, and overall endurance.

An additional benefit of Creatine is that it helps to pull fluids into the muscle tissues, enhancing pumps and providing a greater delivery of nutrients into your muscles when you need them most.

Citrulline Malate is a precursor to the production of nitric oxide, a naturally occurring compound within the body that is crucial to the health of your cardiovascular and the circulatory system.

Increasing your nitric oxide levels by taking Citrulline Malate ensures that you will have amazing skin-splitting pumps and greater vascularity while you train. This also means that more nutrients will be delivered to your muscles.

Beta-Alanine is a hugely popular amino acid that acts as a buffer to attenuate the accumulation of lactic acid within your muscles. This helps to increase endurance and expedite the recovery process by flushing out metabolic waste products from your muscles while reducing acidity throughout the body.

Another ingredient that is worth mentioning is the Black Pepper Fruit Extract. This also stimulates the circulatory system and provides a much-needed boost to your blood flow, improving the absorption and utilization of the ingredients in this product.

I am thoroughly impressed with what the manufacturers achieved with Transparent Labs Stim-Free Pre-Workout.

This product not only delivers great quality but the number of ingredients included in every serving will ensure that you are receiving a clinically effective dose that will do what is promised on the label.

There are far too many pre-workout supplements on the market that use proprietary blends, and this basically means that you have no idea how much of each substance you are receiving. How are you supposed to know the product works if you don’t even know that you are receiving an effective dosage?

Thankfully this is definitely not the case with the excellent Transparent Labs Stim-Free Pre-Workout as you can clearly see exactly how much of each ingredient is in each serving.


This product comes in the form of a powder which can be very easily mixed into water, so if you train in the early evening after work like most people then you can simply throw scoop of Transparent Labs Stim-Free Pre-Workout into a shaker and then add some water when you are ready to leave the office and head for the gym.

There may be some of you out there thinking that it would be better to have a product like this in the form of a capsule that this is simply not feasible because the serving sizes very large due to the vast number of ingredients in the formula.

Taste / Composition / Mixability

This product tastes absolutely fantastic, which comes as little surprise because Blue Raspberry is a very easy flavor to get right.

The composition of Transparent Labs Stim-Free Pre-Workout is second to none, mixing smoothly into water and leaving a translucent liquid with very little in the way of gritty texture or sediments floating on the bottom.

Is it Worth the Money?

By now it should be quite obvious to you that you will be receiving great value for money if you purchase Transparent Labs Stim-Free Pre-Workout.

High-quality ingredients are provided in effective doses, and the manufacturer has placed a great deal of emphasis on minimizing the use of unnecessary fillers, binders, and other artificial ingredients.

Transparent Labs Stim-Free Pre-Workout is definitely worth the money.

Wrapping Up

Transparent Labs Stim-Free Pre-Workout offers amazing value for money and is almost guaranteed to give you some of the best workouts of your life.

I have never been a fan of pre-workout supplements that use proprietary blends because of the lack of transparency provided by the manufacturer raises a lot of questions about the overall quality of the product.

Transparent Labs definitely lives up to its name by clearly displaying what ingredients they use and how much you will find in your supplement.

Pre-workout supplement really don’t get much better than Transparent Labs Stim-Free Pre-Workout, and if you need a product is free from stimulants and won’t cause you it is or anxiety then you really can’t go wrong with this one.
