im goin go ahead n say arnold calves was his...
Who knows? Here is an interesting interview DC did with Duchaine in his old Hardcore Muscle newsletter where Duchaine mentions guys in the 70's using silicone injections in certain bodyparts:
HM: Some people get nerve damage from …
Dan: Well, Nadler showed me step-by-step instructions on how to put silicone in your calves. Just long small amounts in your calves, not large amounts, and your muscle will encapsulate it. And you can keep building it up and building it up. You could do biceps too.
HM: How do you put the silicone in though?
Dan: A needle, but of course it is not legal to do it in this country. But you could easily do it in Tijuana.
HM: Could be dangerous with the silicone though – like it is with breast implants.
Dan: That’s a little different; you’re only using small amounts. When they originally did silicone in the 70′s before they put it in the sac, they put a massive amount in the gland. But if you used a small amount and let the body encapsulate it, you could do it. I would do it.
HM: Will it move with the muscle though?
Dan: Yes it will. That’s the nice thing about it. Nadler can’t do it in this country but I could ask him – if he went to Tijuana, would he do it there? You would have to go back and forth because you couldn’t do it all at once.
HM: Could someone do it themselves?
Dan: (Dan got a good chuckle out of that one.) I could probably do it. I have no fear of needles. I’ll ask him.
