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
  • Betaalanine: 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…
