PreSeries Lean Pre-Workout Overview

What Is PreSeries Lean Pre-Workout?

You only need to take a quick look at the ingredients list to see that Transparent Labs Lean Pre-Workout is likely one of the most effective pre-workout supplements that money can buy.

What sets this product apart from much of the competition is that it has been specifically formulated for those of you who are dieting and trying to shed body fat, so you’ll find a potent combination of thermogenic compounds to melt those pesky pounds right off.

If there is one thing that needs to be said about this product is that all of the ingredients are provided at dosages which have been shown to be effective, so you will find no vague “proprietary blends” on the ingredients list as full transparency is guaranteed.

How and When Do I Take It?

As per the manufacturer’s recommendations you are to take one scoop of Transparent Labs Lean 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 the stimulants it contains; once you are satisfied you tolerate the ingredients well you can graduate to a full dose for increased intensity.

Ensure you never use more than two scoops of Transparent Labs Lean Pre-Workout 24-hour period, and try to avoid using this product later in the day because the stimulant content may affect your quality of sleep.

Benefits of Preseries Lean Pre-Workout

When you are trying to lose considerable amounts of fat one of the most important things that you should take into consideration is the maintenance of your existing lean muscle mass.

It is all too easy to perform excess amounts of cardio, diet on insufficient calories, and end up losing all of the muscle that you have worked so hard to build.

With this in mind, the BCAA content of Transparent Labs Lean Pre-Workout is incredibly important because it helps to stimulate muscle protein synthesis and reduce the catabolic effects of tearing down your muscle tissues when you train intensely.

Remember that muscle is not built in the gym, and in fact, you are causing damage to your muscle tissues during training, so using BCAA ensures that you are not taking two steps back for every one step you take forward.

Another important aspect of retaining your lean muscle mass is to ensure that you are providing your body with sufficient stimulus so that it “knows” to hold onto the muscle it has rather than sacrificing it to meet the energy demands being placed upon it.

This is where some of the performance-enhancing ingredients come into play.

Beta-Alanine is an awesome ingredient that acts as a lactic acid buffer, reducing acidity in your muscles and helping to flush out the waste products that accumulate during workouts.

Citrulline Malate acts as a precursor in the production of nitric oxide, which helps to stimulate the circulatory system and increase blood flow throughout the body. This helps to enhance pumps while also increasing the delivery of nutrient-rich blood and other fluids into your muscles.

Aside from the performance-enhancing, and recovery aspects of Transparent Labs Lean Pre-Workout, you will also notice a potent combination of thermogenic ingredients that will keep your metabolism humming and help to mobilize your fat stores so that they can be burnt off.

Raspberry Ketones and Synephrine HCl promote fat mobilization and cause your body to burn more calories on a daily basis by popping your metabolic rate. These ingredients also give you much needed mental clarity to improve your focus and concentration in the gym.

Speaking of mental benefits, we are all familiar with just how effective Caffeine can be, so you will be pleased to see that there is a 180 mg dosage provided in every serving. This is roughly equivalent to 2 or 3 cups of coffee.

Are There Any Precautions?

Always follow the usage guidelines provided by the manufacturer on any supplement you purchase and speak with your doctor before taking any supplements.

Transparent Labs Lean Pre-Workout promotes stimulatory effects and contains caffeine so please exercise caution prior to use if you are particularly sensitive to caffeine or other stimulants.

Because of its vasodilatory effects, Transparent Labs Lean Pre-Workout should be avoided by anyone who has ever suffered a heart attack or other form of cardiovascular disease.

What’s more, Transparent Labs Lean Pre-Workout should not be used by pregnant or breastfeeding women, nor should it be used by individuals under the age of 18.

Consult your doctor or physician prior to using Transparent Labs Lean Pre-Workout if you have any pre-existing medical conditions or if you are currently using prescription medication.

Taste / Composition / Mixability

Transparent Labs Lean Pre-Workout comes in a very tasty Blue Raspberry flavor, and the powder mixes very quickly and easily into water without you having to stand there shaking it like a crazy person.

Even though there is a vast selection of ingredients in this product, they all seem to mix very nicely with water, with no other unpleasant sediment at the bottom or gross layer floating on top.

Once mixed, you should be left with a light translucent solution that you will find to be an absolute pleasure to drink.

Is it Worth the Money?

There is absolutely no doubt in my mind that Transparent Labs Lean Pre-Workout offers fantastic value for money.

As mentioned above, this product doesn’t use proprietary blends, nor does it hide any of the dosages of the ingredients it contains, so you know exactly what you are getting in every serving.

Wrapping Up
