what you are thinking of is a product called Synthol. its not a steroid but its an oil that some bodybuilders inject straight into the muscle that makes it swell up like a balloon. it looks ridiculous and is damaging to the muscle fascia. when you see pictures online of these skinny guys with huge cartoon biceps its because they have used synthol. google Greg valentino to see what a synthol using moron looks like.

lol. You are a moron and if you think like that, steroids are the last thing you should ever try.

The other guy is flat out wrong! lol @ tricking your body to produce more muscle LOOOOOL STUPID.

Don't do steroids. And don't ask anyone in this forum about steroids, they have no idea what they are talking about.

That's not how it works, they don't just pump it into the arm to make it look bigger. People aren't water balloons and their bodies don't work like that. Steroids work by tricking the mind into producing extra muscle

xylocaine is steroid...just dont know how floyd applies it

Is there a steroid that just fills up a certain part of the arm? I can't understand why body builders who use steroids can't flex their muscles. Is it because there's a synthetic material they put in their arms to make it look bigger?
