The public just seems to know that Captain America was made all big and whatnot from his previous scrawniness via Murrican science. General Ross used something that was similar to the original, but still a different process to make Emil Blonsky all uber. There was no vita-ray treatments. It was all deep, painful injections of this alternative serum into the bone marrow and whatnot. They referenced it originated from World War Two but called it the Bio-Force Project.<br/><br/>Combining it with gamma rays is what made Bruce Banner the Hulk.
