Why the difference in forearm you ask?Why the are the fibers popping out like crazy?Why does he look "mutantnized"?Upped the dosage of Pharm Grade GH and slin?No.He abused Legit Kigtropin that has pharm grade IGF-LR3 in them.
Also notice his fingernails in the first video.That is how someone's nails on Pharma Grade GH and Insulin look like, also notice his forearm, exactly the same as the first picture where he is wearing his flex lewis shirt.Now compare that to the last picture where his head seemed to have shrunk on his body. This IS the effect you get on legit kigtropin, where your head doesn't look like it belongs on the body, with muscle fibers popping out of skin that is paper thin. Notice the difference in thickness of the skin too, and how the shirt sits different on the body, with the 3D effect full on even when covered in a shirt.
Flex Lewis's arms
This is not a discussion about what was in the legit Kigtropin. Everybody knows that what was in it changed a couple of times, and now it's sugarwater. But you are right, he's obviously using pharma GH and pharma grade IGF-1. The latter is what makes the difference in today's top bodybuilding, and the reason why Flex will win.
What is going on with Branchs arms? Why do they look so odd?
Flex's forearms make a big difference to the overall look. Branch is rapidly approaching Palumboism Stage II.
Flex should do the open division Olympia. He's better than Branch and would push for top 6.
