Let me rephrase: How can a bb organization or any bb for that matter frown upon any bb injecting anything into their body?
No you idiot. Get it right.
It doesn't have anything to do with the injection or what was injected in the first place.
BBing is a visual sport, and it's based on what you look like. If you have lumps, no matter from it being an allergic reaction to grapefruit, a bad injection site or a bee sting....you should be marked down for it.
In this case, Iris Kyle has been rumored to have these lumps and been warned about it before this. It's more on the obvious side of why the the lumps are there, but Chick is trying to say to you thick headed dimwits, that he and the IFBB don't care HOW the lumps got there. But if it's obvious and distracting from your physique (it is a BBing show afterall, right?), then you'll be marked down for it.
