We are MUTANT – Experimental Muscle Modifiers. MUTANT will deliver experimental musclebuilding formula’s that are designed to help you build freaky, mutated muscle. MUTANT MASS was the first to arm the Nation of MUTANTs with the world’s #1 weight gaining formula. Since 2006, MUTANT MASS has become the gainer of choice among bodybuilders and powerlifters in over 85 countries worldwide. After years of experimentation, the MUTANT R&D lab has developed new and powerful bodybuilding supplements. Their plan was simple – to modify your regular workout into absolute iron-crushing chaos that forces your muscle and strength into the freak zone! No “curls for the girls” or “coreball crunches” in the MUTANT lab – nope, MUTANT is for those who want massive size and strength, period.
