So Bob, since synthol is injected inside the muscle wouldn't it be rather difficult to determine?
it doesn't look like synthol to me, site injection, though, not so sure.
synthol - injecting of large amounts of oil into a muscle to increase it's volume
site injection - injecting a substance (certain steroids, caverjet) that causes temporary muscle inflammation to increase its volume
how can you determine if its either? muscle looks flexed (has a peak) even when relaxed
