That doesn't make sense , I could be wrong ,but bodybuilders usually try to enhance their weakest body parts not their strongest .
Many of the things don't make sense necessarily. Not saying wnhancing the quads does or doesn't make sense, there's different ways of looking at it. Putting enhancements in already huge bodyparts is "easier" as it doesn't look as obvious - like here, many can't spot it but it's obvious to me and many others. Try inflating weak rear delts or small biceps with a lot of oil and it's much more obvious.
Regarding Ramy's quads, even Palumbo said it looks like there's stuff in there and that he heard it's something "water based" that they use in Kuwait, which to me means hyaluronic acid. It was that obvious.
If Heath puts stuff deep in his arms, as I'm sure he has done, no one can tell necessarily.
People were saying how come Ernie Taylor put so much in his triceps, how come not in other parts like calves or chest? That means he didn't put oil in his triceps, would be idiotic. Idiotic or not, that's exactly what he did.
