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.
