i agree synthol will ruin you!!! i was in a show recently and this kid had tons of synthol in his delts.....man everybody just laughed at him. if you want this response to your physique then by all means do so. i will be right there to laugh at your dumb ass.
thx to those who answered w/o flaming. i don't fuckin use synthol jackasses. my friend uses it in his biceps/triceps and he keeps it in his car and asked me if heat would ruin it.
jackasses? we are the ones that are jackasses for laughing at someone who cant workout to make their muscles bigger. i think you friend is the jackass with oil for muscle mass.
