Muscle
Even superheroes have days when they need a little extra strength. Grab a one quart can of all-natural, universally legal Muscle (accept no substitutes!), and get ready to rumble!
CAUTION: as with all Brooklyn Superhero Supply Co. Superpowers, we advise a) extreme caution when opening the container (in fact, we advise against ever opening it - are you really that keen to tamper with the essential nature of our universe?) and b) we would like to make very clear that this is not an edible product. Don't put it in your eyes, on your hair, or in your favorite food.
