AminoLean is a unique supplement that combines amino acids, micronutrients, and metabolism-boosting ingredients to help you get leaner, stronger, and healthier.


Each serving of RSP Nutrition Amino Lean contains all of the essential amino acids needed to repair your muscles after training sessions.

AminoLean provides 5g of amino acids per serving, and unlike BCAA supplements, it contains all nine essential amino acids that make a complete protein.

Although the label does not state exactly how much of each amino acid it contains, AminoLean contains these amino acids:

  • L-Glutamine
  • L-Arginine
  • L-Leucine
  • L-Isoleucine
  • L-Valine
  • L-Citrulline
  • L-Histidine
  • L-Lysine
  • L-Threonine
  • L-Methionine
  • L-Tyrosine

The presence of EAAs in AminoLean is crucial for muscle growth and recovery, as these amino acids aid in protein synthesis and help reduce muscle breakdown during exercise, enabling users to build and maintain lean muscle mass.

Along with these amino acids, RSP Amino Lean also contains Beta-Alanine and Taurine.

Beta-Alanine is especially useful as it has consistently been proven as an effective supplement for improving athletic performance, increasing exercise capacity, and reducing muscle fatigue.

Weight Management Ingredients

Another reason I believe that AminoLean is an excellent product is that it contains four natural fat burners with evidence to suggest they can improve weight loss efforts.

The four weight management ingredients are:

Green Tea Extract:

Green tea extract is rich in antioxidants, particularly catechins, which have been shown to positively impact weight loss and management.

The most well-known catechin is EGCG (Epigallocatechin gallate), which has been found to increase fat oxidation and improve thermogenesis (the process by which the body generates heat and burns calories).

Green Coffee Bean Extract:

Green coffee bean extract is derived from unroasted coffee beans and contains a high concentration of chlorogenic acid.

Chlorogenic acid has been shown to influence glucose and fat metabolism, which can help reduce the absorption of carbohydrates and support the breakdown of fat.

CLA (Conjugated Linoleic Acid):

CLA is a naturally occurring fatty acid found in meat and dairy products.

Research suggests that CLA may help promote weight loss by influencing the body’s energy metabolism, reducing body fat storage, and increasing fat breakdown.

Some studies also indicate that CLA can help preserve lean muscle mass while promoting fat loss, which is essential for maintaining a healthy body composition.


L-Carnitine is an amino acid vital in transporting long-chain fatty acids into the mitochondria, where they can be burned for energy.

By facilitating the use of stored fat as fuel, L-Carnitine can help increase fat oxidation, thereby supporting weight loss and weight management efforts.

Additionally, L-Carnitine has been shown to reduce fatigue and improve exercise performance, leading to more effective workouts and increased calorie burning.


Amino Lean contains a combination of natural sources of caffeine, such as green tea extract and green coffee bean extract, to provide sustained energy, mental alertness, and additional metabolism-boosting effects.

RSP Nutrition Amino Lean is one of my favorite supplements due to its versatility and multiple benefits, making it one of the best supplements for weight loss and muscle gain.

Its unique ingredient blend not only supports muscle building and fat reduction but also contributes to overall health optimization.

Improved Muscle Recovery and Muscle Growth

AminoLean’s comprehensive formula, containing both EAAs and BCAAs, supports muscle growth and recovery.

These amino acids facilitate protein synthesis and help minimize muscle breakdown during exercise, allowing users to effectively build and maintain lean muscle mass.

By incorporating AminoLean into their fitness routines, athletes and fitness enthusiasts can experience faster recovery and enhanced muscle growth, resulting in improved overall performance.

Increased Fat Burning

Thanks to its unique weight management and appetite control blend, which includes ingredients such as CLA and L-Carnitine, AminoLean promotes the breakdown of stored fat and helps suppress appetite.

This makes it easier for users to achieve a calorie deficit, leading to more efficient fat-burning and weight loss.

With Amino Lean, individuals can build lean muscle and effectively shed excess pounds, paving the way for a more sculpted physique.

Energy & Focus

One of the standout features of AminoLean is its natural caffeine and energy blend, which provides a steady and sustained energy source throughout the day.

This energy boost enables users to maintain focus and mental alertness during workouts, translating to more effective and productive training sessions.

But the benefits of Amino Lean don’t stop at physical performance; its unique formulation may also offer cognitive advantages.

By combining natural caffeine, amino acids, and other ingredients, AminoLean helps improve focus, mental alertness, and overall cognitive function, resulting in not only better workouts but also increased productivity in daily life.

Side Effects

While RSP Amino Lean offers numerous benefits, it’s essential to be aware of the potential side effects of Amino Lean and how to minimize risks.

As with all dietary supplements, some individuals may experience unintended or undesirable effects.

Although Amino Lean is not a medication and does not have “side effects” in the traditional sense, there are still potential risks.

To minimize the potential side effects of Amino Lean, it’s crucial to read and follow the instructions on the label carefully.

If you’re unsure whether Amino Lean suits your needs, consult a healthcare provider before incorporating it into your fitness routine.

Insomnia: Amino Lean contains caffeine, which can interfere with sleep if consumed too close to bedtime.

To avoid this issue, avoid taking it before or during a nighttime workout or within a few hours of your intended sleep time.

Nausea and Upset Stomach: Some users may experience mild nausea or stomach upset when first taking Amino Lean.

To minimize this risk, consider starting with a lower dose and gradually increasing it as your body adjusts to the supplement.

Additionally, taking Amino Lean with a small meal or snack may help reduce gastrointestinal discomfort.

Headache: In rare cases, users may experience headaches when taking Amino Lean.

This side effect may be attributed to the caffeine content or individual sensitivity to specific ingredients.

If headaches persist or worsen, consider reducing the dosage or discontinuing use.

Dizziness: A small number of users may experience dizziness after taking Amino Lean.

This side effect is generally temporary and may be due to individual sensitivity to certain ingredients. If dizziness continues or becomes bothersome, consult a healthcare provider before continuing the supplement.

How to Use RSP Amino Lean

To get the most out of Amino Lean, it’s essential to follow best practices for usage, dosage, and stacking:

Recommended Dosage and Timing

The recommended dosage of Amino Lean is one scoop mixed with 8-10 ounces of water, taken once or twice daily.

Each dosage of Amino Lean contains 5 grams of EAAs and 120mg of caffeine, and one dosage of this supplement is two “scoops.”

I take two doses or four “scoops” of AminoLean pre workout or one dosage (two scoops) as an afternoon pick-me-up as needed.

You can use this supplement in multiple ways, but using Amino Lean as a pre workout supplement is an excellent way to maximize its benefits.

In fact, taking AminoLean pre workout is one of my favorite ways to get more out of my workouts.

For optimal results, I recommend consuming Amino Lean pre workout 15-30 minutes before your training session.

This timing ensures you receive a boost in energy and support for positive body composition changes during your workout.

Drinking Amino Lean pre workout has advantages over many other pre workout supplements because it has a moderate amount of natural caffeine per serving that won’t make you jittery.

Additionally, Amino Lean can be consumed during your workout, as the amino acids in the formula help fuel your body throughout longer training sessions.

This, in turn, can help reduce muscle breakdown, initiate the recovery process, and minimize muscle soreness.

Beyond its workout applications, you can also consider using AminoLean as an alternative to your daily cup of coffee, whether as a morning pick-me-up or a mid-day energy boost.

However, you should avoid consuming it too close to bedtime, as the caffeine content may interfere with sleep.

Mixing Instructions and Best Practices

Mix one scoop of Amino Lean with 8-10 ounces of water and shake well. Adjust the water amount to achieve your desired taste and consistency.

Consuming Amino Lean on an empty stomach may cause gastrointestinal discomfort for some users. If this occurs, try taking the supplement with a small meal or snack.

Stacking with Other Supplements

Amino Lean can be stacked with other supplements to support your goals.

For example, you may combine Amino Lean with a protein powder supplement to further promote muscle growth and recovery, or with a citrulline malate supplement to get a bigger “pump” during your workout.

Always consult a healthcare provider or a certified fitness professional before stacking supplements to ensure safety and compatibility.

Flavor Rating: 4.8/5

RSP Amino Lean offers a variety of delicious flavors that cater to different taste preferences, ensuring that there’s something for everyone to enjoy.

Personally, my favorite flavors are the Vegan Amino Lean Pineapple Coconut and Acai, which both taste fantastic.

I’ve never had any issues with the flavor or mixing of Amino Lean, as the supplement dissolves quickly in water, providing a smooth and enjoyable drinking experience without clumps or residue.

The Vegan Amino Lean has a more natural taste than the original formula, which I truly appreciate.

To get the best taste and texture, I recommend mixing one scoop of Amino Lean with 8-10 ounces of water and shaking well.

You can adjust the water amount according to your desired taste and consistency.

For a colder, more refreshing beverage, consider adding ice or using chilled water.

RSP Vegan AminoLean Review

Although the original RSP Nutrition Amino Lean formula is great, RSP Nutrition also makes Vegan AminoLean, a 100% vegan amino acid supplement that I believe is even better!

The main difference between RSP Vegan AminoLean and regular AminoLean is the source of the protein.

The classic AminoLean formula is made with amino acids taken from animal sources, while RSP Vegan AminoLean is made with plant-based amino acids.

This means that RSP Vegan AminoLean is suitable for vegans and vegetarians, while regular AminoLean is not.

Both supplements contain Green Tea Extract, Caffeine, and CLA.

However, Vegan AminoLean is free of animal products, artificial sweeteners, gluten, and soy, making it suitable for people with specific dietary restrictions.

Additionally, Vegan AminoLean contains better caffeine sources (guarana and organic matcha).

I prefer Vegan AminoLean because it is all-natural and does not contain anything artificial!

It is slightly more expensive but also a more natural product.

RSP AminoLean Max Review

Amino Lean Pre Workout Review

RSP AminoLean Max is RSP Nutrition’s newest pre workout supplement, with the highest caffeine content of any of their supplements.

I bought one bottle of RSP AminoLean Max as soon as it was released, and I have had a fantastic time using it so far!

Like Vegan AminoLean, AminoLean Max is vegan and contains no artificial flavors or dyes.

AminoLean Max contains a beneficial amount of BCAAs (1.5 grams in a 2:1:1 ratio) and a small quantity of other EAAs.

The amino acid content of AminoLean Max is lower than other AminoLean products, but it is still beneficial.

A key difference in RSP AminoLean Max is that it contains 1.6 grams of Beta-Alanine, a well-researched supplement for assisting with various goals.

Additionally, AminoLean Max contains 250mg of natural caffeine, 250mg of L-Tyrosine, and additional ingredients to help you “get a pump” in the gym and have energy for longer workouts.

AminoLean Max provides a nice jolt of energy for the start of long workouts and contains safe, effective ingredients to promote long-term muscle growth!

Concluding Thoughts – Should You Buy Amino Lean?

I have been using RSP Nutrition Amino Lean for years, and I believe it is a very beneficial supplement.

However, you should decide for yourself if you want to buy it.

When you spend your hard-earned money on a product that is supposed to improve your health, it better work! I have wasted (way) too much money in my life on useless supplements and products that I wish I could have back.

RSP Nutrition Amino Lean is well-formulated and has worked for me. It is one of my favorite supplements, and I believe it is the best EAA supplement and one of the best pre workout supplements.

In my experience, this supplement can provide energy for workouts and help improve your body composition.

If those are your primary goals, this would be a good supplement.

I hope my RSP Nutrition Amino Lean Review has helped you. Please let me know if you have any additional questions.
