Ingredients: What’s In Transparent Labs Lean Pre Workout?
Lean Pre Workout’s active ingredients are two types of caffeine, theanine, citrulline, beta-alanine, betaine, BCAAs, ALCAR, choline, and theobromine.
These give Lean a few strong effects, built on smart design. Let’s look at what each of them does…
- Caffeine Anhydrous: you know it – better performance, more energy, and more fat loss
- DiCaffeine Malate: like caffeine, but longer lasting and better in the gut
- Theanine: the best synergist to improve the energy of caffeine and offset the side effects
- Citrulline: improves blood flow to muscles for better performance and pumps
- Beta–alanine: the best endurance buffer to help you work harder for longer and perform better
- Betaine: a synergist for citrulline, further boosting nitric oxide levels and recovery between sets
- BCAAs: a mild endurance supplement and muscle protector, but also underpowered
- ALCAR: a fantastic brain and muscle energy support compound to synergize with caffeine and B-alanine
- Choline: a compound to support acetylcholine, which improves cognitive function and mood
- Theobromine: circulation support to reinforce the blood flow benefits of citrulline and betaine
These are excellent groups of synergistic ingredients. This means that each benefit has 2 or more ingredients supporting it, giving you the most robust and reliable results…
