Twinlab: Mass Fuel Xtreme

Packed With Free-Form BCAA's!

Super Efficient Macro & Micro Nutrient Formula Promotes Lean Muscle Growth!*


ABOUT
REVIEWS

A powerhouse formula that delivers 600 incredibly efficient mass-promoting calories.* Formulated with our exclusive 4-stage time release carb blend for sustained energy, 50 grams of fast and slow release proteins packed with BCAAs, and super-efficient fats from MCT oil (Medium Chain Triglycerides) making it our best lean mass and muscle builder EVER.*

Xtreme Results

Protein Powder System: Infuse massive amounts of multi-sourced, enzyme-assisted (for easy digestibility) proteins to fuel growth and recovery. Whey Concentrates and Isolates, Caseinates, Milk Protein, L-Glutamine and Glutamine Peptides and free form BCAAs (L-Leucine, L-Valine, L-Isoleucine) to feed hungry muscles.*

Sustained Energy Carb Blend: We sweat the details on our next-gen carb matrix. Maltodextrin, Isomaltulose, Waxy Maize and Glucose flood muscles each in precisely timed waves generating a sustained energy band - not "spike and crash" - to help keep muscle fibers charged throughout your entire workout.*

Super Efficient Fats: Fat provides the most dense source of nutritional energy you can get, but if not used up by the body it is stored for future use.* Virtually all of the fats in Mass Fuel® Xtreme are Medium Chain Triglycerides (MCT), a unique "use it or lose it" fat that if not burned immediately during exercise, flushes out of the system...remember, there's a big difference between looking phat, not fat!*
