Frequently Asked
Questions

What’s the difference between Bulk and Lean pre-workouts?

Bulk is our clinically dosed pre-workout powder for athletes, bodybuilders, and gym-goers looking to build lean muscle mass. Lean is an advanced thermogenic pre-workout formula that supports fat-burning pathways while increasing athletic performance.

Which Transparent Labs supplements stack well together?

Are Transparent Labs' best-selling supplements third-party tested?

Yes, you can view the results on our Third-Party Tests page.

What makes Transparent Labs supplements different from other brands?

You get what you pay for, and many supplement companies are just in it to move as much product as possible at the expense of quality, efficacy, and safety. We’re proud to offer industry-leading formulas with an unmatched commitment to using high-quality raw materials, natural ingredients, and full-disclosure labeling practices.
