Marvel Super-Heroes #50

While being transported to the planet of Wundagore II, the Hulk finds himself transforming once again into puny Banner. Arriving at the base of the High Evolutionary who needs the power of the Hulk to battle his bestial New Men, the Evolutionary is disappointed to find a normal human instead of a gamma spawned powerhouse but decides he can still use Banner as an ally by evolving him a thousand years into humanity's future.
