Let’s look at the ingredients in detail.

Transparent Labs LEAN Supplement Facts

Citrulline Malate

Citrulline Malate is the powerful ingredient in this product and is a dominant part of pre-workout supplements. It helps improve strength and muscle endurance. Preferred over L-arginine due to better efficacy, it can improve leucine use during exercise, allowing for a better workout. It improves the athlete’s overall performance because of its ability to assist in fatigue and performance during high-interval training.

According to one scientific publication, Citrulline has cardiometabolic health benefits and was found to increase growth hormone post-exercise. There is also scientific evidence showing that Citrulline increases anaerobic activities such as weightlifting and reducing post-workout pain.


Betaine can set going muscle growth in the absence of testosterone, resulting in greater power and reducing tiredness to interrupt an athlete’s continuance during a workout. Due to this, the athlete sees an increase in the total number of reps and weight lifted, which works well for muscle growth.


BCAAs (branched-chain amino acids) constitute three of the nine essential amino acids that our bodies require to make proteins. Without an adequate quantity of all nine essential amino acids, you won’t be able to make the best use of protein synthesis, which leads to muscle growth.

That also means just supplementing with BCAAs alone with not help much. But it’s important to know that leucine is the most important BCAA for protein synthesis. Leucine activates mTOR, the gene that carries out protein synthesis, and has been found to boost strength and performance and prevent lean muscle decay.

Isoleucine and valine also promote muscle growth and increases metabolism. Apart from the muscle-building benefits, BCCA’s have also shown to provide positive effects on the workout, fatigue, pain, and muscle recovery.


Beta-alanine is a non-essential amino acid that makes carnosine, reducing the amount of lactic acid in the muscles. High levels of lactic acid accumulate in the muscles during exercise, resulting in pain, discomfort, and the burning that you experience while performing intense workouts.

Carnosine acts as causes a barrier against lactic acid build-up and reduces soreness and fatigue, which improves workout capacity. Many pre-workout supplements do not incorporate Beta-Alanine, but LEAN does due to its ability to increase carnosine levels which can go down considerably during workouts.

N-Acetyl L-Tyrosine

L-tyrosine aims more on your energy and awareness to ensure a better workout all the time. It helps provide relief from stress and offers a good mental focus and sharpens memory, and improves performance, giving you overall good mental health.

Choline Bitartrate

Choline bitrate is a focus ingredient, although when compared with Alpha GPC, it may not be as effective as a nootropic. Nevertheless, the 500 mg of choline bitartrate is good enough to improve focus.


Theanine is a stimulant whose effects are like caffeine but are most effective when used alongside caffeine. The synergistic effect of these two bits of help lessens some side effects like jitters which result because of the consumption of high dosage caffeine products.

Caffeine Anhydrous

Honestly, 180 mg of caffeine is a low dosage as compared to most pre-workout supplements. However, it does not matter much in this case as it is combined with the other stimulants. But if you’re searching for a high-stimulation pre-workout, LEAN is not for you. If you need a solid pre-workout that can support daily or regular usage, then LEAN is good for you.

Mucuna Pruriens

Mucuna pruriens helps reduce cortisol (the stress hormone) and boost mental health.
However, the 70 mg here is considerably lower than the generally recommended dosages. The recommended dosages can range from 300 mg to 1,000 mg per day. However, the fact is that there is very little research around this ingredient in the context of a pre-workout supplement, so it’s difficult to assess whether 70 mg is a sufficient dosage or not.

Chromium Picolinate

Chromium is an effective mineral that plays a very vital role in regulating the metabolism of glucose. It also regulates insulin sensitivity. It has been shown to create a minor reduction in blood glucose in diabetics, but this effect is not observed in people without diabetes. 200 mcg is enough to be an effective dosage, but again, only for individuals with diabetes.

Thyroid Support

Lean pre-workout also has ingredients for thyroid support. It’s important to keep the thyroid healthy as it plays a vital role in the body’s metabolism. Other important Transparent Labs LEAN Pre-Workout Ingredients

The ingredients listed above make up the major portion of LEAN. However, other ingredients are present, such as L-norvaline, BioPerine, hordenine, synephrine, zinc, and guggulsterone. These are beneficial to help in muscle growth and increase metabolism, energy, and cognitive function.

Benefits and effectiveness of Transparent lap LEAN pre-workout supplement

After learning about all the ingredients present, most of the users would like to ask about the presence of caffeine intake in the product. And surprisingly, the amount of caffeine in this pre- workout supplement is 180 milligrams per scoop, which is just little more in what you would get in a small Starbucks coffee.  

So Following are the benefits of using Transparent Labs LEAN Pre – Workout

  • Improved Focus 

The theanine and tyrosine are natural chemicals that may have an effect in reducing the jitteriness associated with a big hit of caffeine. The  theanine in particular can be useful when consumed before hitting a caffeine high, because it can mitigate the effects of caffeine and keep you from feeling overstimulated.

  • Endurance is Improved 

The common thing in most of the pre-workouts is the presence of beta-alanine. Sometimes this thing can give some small harmless tingling sensation in the body. So the presence of citrulline and norvaline could certainly help mitigate this. Also the branched chain amino acids could also help improve endurance.

  • Improvement in Power 

Citrulline has shown improvement in power specially in cyclist and tennis players. Betaine, compound found in few plants and in beets, also said to improve power.

  • Improved Digestion 

Black pepper extract helps other ingredients within the medication absorb more effectively, which leads to a faster absorption process and increased effectiveness.

  • Fat loss

The biggest USP of the product is this. Well a study conducted on 40 subjects interestingly found that  50 milligrams of the product did improve metabolism rate by over 65 Calories that to without increasing the hunger. This product when combined with food can certainly increase the amount of calories in accordance to the food we eat. 

  • Improved Thyroid activity 

The presence of guggulsterones actually improves and conduces the thyroid activity. It is harder to lose fat if your thyroid is not working optimally.

How to Use Transparent Labs LEAN Pre-Workout Supplement?

You should take LEAN at least 20-30 minutes before your workout. The company suggests you start with 1/2 scoop and 6-8 fl. oz of water to check its suitability. If using a full scoop, mix it in 12-16 oz of water to reduce its typical sour taste.


As you’d probably expect with a pricey workout like LEAN mixes pretty well. You can mix it by shaking or use a spoon to dissolve all the powder.

Transparent Labs LEAN Pre-Workout Pricing

Transparent Labs LEAN Pricing

You can buy 30 servings (that’s a little over 1 lb.) for $49. That means one scoop costs $1.63, which is expensive as compared to most other pre-workout supplements. That said, nearly every LEAN ingredient is dosed reasonably higher than most of its competitors, so the high price is justified

Taste of Transparent Labs LEAN Pre-Workout

The taste of Green Apple is more like sour apple candy, which is quite obvious as one of its ingredients includes citric acid, which is pretty tart. Transparent Lab suggests you mix one whole scoop with 1.2 cups of water (10 fluid ounces), but the drink turns out to be pretty sour. So if sour is not what you like, try mixing it with two cups of water.
