High-end serums often required only the simplest preparation methods.
After two busy hours, Master Wick obtained a flawless sample of the Extremis Virus.
Both the Evolution Serum and the original Extremis Virus worked by altering genes.
As such, they achieved similar results through different means, both serving as ways to strengthen the body.
The Evolution Serum was a weaker version of the super-soldier serum, but it could still give someone a peak human physique.
