It's possible that he took the finite formula and injected it in Cap, but I somewhat expect the serum to somewhat counteract that. Even if that's not the case, even if he took the finite formula and injected it into Cap, or removed the SSS and injected the finite formula simultaneously, it could not have been more poorly explained.
