Hhhhmmm, interesting. My serum has an oddball affect. While some patients have not survived the operation. Some lived for an average of one year. Some like me, have lived on for years. The biggest size effect would be the regeneration process, otherwise know as the healing affect, and what I call the rage mode. The serum allows the patient to heal their wounds faster than a normal human being. Even if the individual has lost a limb, it will grow back. As if their senses have improved tremendously through out the process, some have acquired the ability to "rage". To use their ability to increase their fighting abilities ten fold.

Interesting. Further test would be needed, as those survival odds are not promising enough.
