ERGOGENIC TRAINING & FAT-LOSS FORMULA
Select a Flavor
LEAN was developed for a single purpose: to be the most exceptional cutting pre-workout supplement, ever.
Lean contains citrulline malate, beta-alanine, and betaine—as well as a potent fat burning and thyroid support complex including acetyl-L-carnitine, chromium picolinate, and zinc—perfect for those looking to target stubborn fat, while simultaneously preventing lean muscle loss.
There's a reason PreSeries LEAN comes in jumbo-sized jugs! Each serving exceeds 15 grams and includes 21 active ingredients synergistically designed to provide a high-intensity pre-workout experience, while focusing systematically on fat loss and additional energy expenditure.
No Artificial Sweeteners
No Artificial Coloring

|We formulated LEAN with ingredients that are supported by clinical studies. For a comparison of LEAN vs other pre-workouts and a full pre-workout buying guide, click here.|
When will my order be shipped out?
All orders ship out the following business day.
How should PreSeries LEAN be taken to maximize its effectiveness?
In terms of timing, we recommend taking PreSeries BULK 20-30 minutes prior to your workout. In terms of how much water to drink with PreSeries BULK, we recommend mixing 8-12 fl. oz of water with 1/2 scoop (to assess tolerance) and mixing 16-24 fl. oz of water with 1 full scoop.
How does PreSeries LEAN compare to other pre-workouts?
Back in 2014 we set out to make the best pre-workout supplement, regardless of price, without the artificial nasty ingredients so common in packaged goods. We wanted something WE would be comfortable taking daily, and confident that it would get the job done.
I am subjected to drug testing for my sport, can I take PreSeries Pre-Workout?
Yes, absolutely. Transparent Labs contains zero illegal drugs of any kind. Depending on how rigorous your drug-testing procedures, we recommend showing your coach or administration our supplement facts panel.
Why doesn't PreSeries LEAN contain creatine?
Large doses of caffeine negates the ergogenic effects of creatine. PreSeries LEAN contains 180 mg of caffeine anhydrous.
What is the difference between PreSeries BULK, PreSeries LEAN, and PreSeries STIM-FREE?
PreSeries BULK is designed to support lean muscle growth and includes a testosterone support complex, while PreSeries LEAN is designed to support fat loss and includes a thyroid support complex. PreSeries STIM-FREE, as the name suggests, contains zero stimulants and has added elevATP.
I don't live in the United States, can I still buy PreSeries LEAN?
Yes - our fulfillment center allows us to ship worldwide. Standard shipping for international orders typically takes 10-14 business days to arrive.

|Citrulline Malate 2:1 | 6,000 mg|
From a performance standpoint, citrulline malate is the “star child” of pre-workout science.
We chose citrulline malate over L-arginine because it provides better absorption, higher plasma arginine levels, and has been found to:
PreSeries LEAN contains 6,000 mg (6 grams) of citrulline malate per serving.
|Beta-Alanine | 2,000 mg|
Supplementing with beta-alanine has been proven to increase cellular carnosine levels, which are quickly depleted during intense exercise [28, 29].
A majority of pre-workout supplements contain beta-alanine, but at significantly underdosed levels. Supplementing with proper dosing, as found in PreSeries LEAN, is shown to:
PreSeries LEAN contains 2,000 mg (2 grams) of beta-alanine per serving.
|BetaPure™ Betaine Anhydrous | 1,500 mg|
Recent clinical studies suggest that betaine supplementation triggers a significant muscle growth response. This response is independent of testosterone and is significantly advantageous alongside typical supplementation protocols.
Betaine supplementation has also been shown to:
PreSeries LEAN contains 1,500 mg of betaine anhydrous per serving.
*(PreSeries LEAN does not contain any form of creatine, as caffeine negates its absorption when taken in synchrony)
|Acetyl L-Carnitine HCl | 1000 mg|
ALCAR is a bioavailable form of L-carnitine readily absorbed across the blood-brain barrier. L-carnitine is an essential molecule required to transport fatty acids across the mitochondrial membrane in cells. In other words, it is a bona fide “vehicle” that carries fats into mitochondria so they can be converted to chemical energy (ATP). Recent evidence suggests that ALCAR also upregulates dopamine receptor expression and protects against neurodegeneration .
PreSeries LEAN contains 1000 mg of Acetyl L-Carnitine per serving.
|Choline Bitartrate | 500 mg|
|L-Theanine | 180 mg|
L-theanine is an amino acid used by the body. When combined with caffeine, L-theanine demonstrates many benefits for athletes, like:
PreSeries LEAN contains 180 mg of L-Theanine per serving.
|PurCaf® Organic Caffeine | 200 mg|
Preseries LEAN contains all-natural caffeine sourced from organic green coffee beans. Caffeine, along with many of the complimenting stimulants and focus-enhancing ingredients in PreSeries BULK are clinically proven to reduce the sensation of effort. Approximately 200 mg of caffeine has been found and confirmed to significantly increase repetitions to failure and readiness to invest effort in athletes [22, 23].
Moderate doses of caffeine have also been found to not negatively interfere with natural thermoregulation like higher (300 mg+) caffeine-infused pre workouts do .
|Theobromine | 50 mg|
Theobromine is the primary alkaloid found in cocoa beans, and is essentially the “little brother” of caffeine. Its functions in the body are suggested to be complementary to those of caffeine, acting as a phosphodiesterase inhibitor and central nervous system stimulant . Research has also found that theobromine has differential contributions to mood and cognitive function when compared to caffeine, providing further insight into the distinct, yet synergistic nature of these naturally occurring stimulants .
PreSeries LEAN contains 50 mg of Theobromine per serving.
|BioPerine® | 5 mg|
BioPerine® is a patented extract obtained from black pepper fruits (Piper nigrum) standardized minimum to 95% Piperine. BioPerine® may be co-administered with various nutrients to enhance their bioavailability in both human and animal. In general, BioPerine® was found to enhance absorption of nutrients by at least 30%.
PreSeries LEAN contains 5 mg of BioPerine® per serving.
