If it's like all of the other's we've seen thus far it's one and one. But it does seem to be a balance between the Serum+VitaRays of Erskine's method and the blue intravenous liquid given to the Hydra Operatives in CA: CIVIL WAR.Is the new serum one-and-done, or do they have to keep taking it?
Mostly I'm guessing due to the time between Walker palmed the serum he found and his capabilities on the next day (or two).
