Key Differences Between Bulk and Lean
Transparent Labs Bulk focuses on ingredients that aid building muscle, while Transparent Labs Lean focuses on ingredients that support weight loss. Both have similar ingredients for performance and energy.
Transparent Labs’ PreSeries Bulk and Lean share many similarities, but their key differences lie in their ingredients, dosages and overall purpose.
Transparent Labs Bulk has more beta-alanine (4,000 mg compared to 2 g in Lean), more BCAAs (4,000 mg to 2,500 mg in Lean), and more betaine HCL (2,500 mg to 1,000 mg in Lean).
