Well, exactly so mrtino. You're right.
What re46hp (an informative pseudonym - me, I use my name) reports on is the use of diffusable oil injections. Nothing new and it's true, they are quite widespread. But they are not muscle and cannot do what muscle does, which is hoist heavy weights in the gym or get defined down to, well, muscle. If all we saw was "injections " as he so fondly believes, then we wouldn't see these girls working their lungs out in gyms, pushing upwards of 100kg squats, and Bulgarian splits with 50kgs. Muscle works like muscle - fats doesn't and of course, neither can "oil". So, yes, it happens, but you have to know what you're looking at. By looking carefully, you can (and will sometimes) find the tell-tale bruising after recent administrations.
But if you think that people like Pamela Gouveia and Kirley Suenia and tons of others at that level are doing this sort of thing (ever) you'd be wrong. Now, if you're poorly developed , or lazy with your diet and training, these girls are going to be way better developed than their armchair critics in this forum. And I think that is where is where all these covert (or overt in this case) accusations of artificial augmentation comes from. They like the look but excuse their own shabby condition or lack of size and shape with a shrug of the shoulders and say, these chicks are basically cheating.
In summary, does it happen? Yes, sure it does. In IFBB and NABBA athletes? No. Only breast implants allowed in BB, all cats. Parenteral oil destroys definition anyway. Juice use as Cothon suggests, yes, definitely. Good or evil, that is always there.
