It doesn't show the effects of consuming the contaminated drink in the movie but, in the script, the victim is a woman.
KID (CONT’D) Mom? WHIP PAN:
Mom is on the floor, her body in a spasm,
eyes rolled back
KID (CONT’D) MOM!!!
INT. GENERAL ROSS’S OFFICE - DAY
GEN. T. ROSS at his desk. Lost in thought. Snaps out of it when his
female aide, MAJOR CABOT, puts some forms on his desk. She moves him
through signing boring requisition orders...
CABOT ...and here’s
something a little more interesting.
He holds out his hand, not that
she hands him a two page fax..
CABOT (CONT’D) Possible
gamma sickness. Milwaukee. Woman drank one of these guarana sodas.
Had more kick than she was looking for.
ROSS Last three were
irradiated fruit, not Gamma...
CABOT Look at the spectrograph in that
path report. Even the FDA didn’t approve that. Whatever it was it
was concentrated. Got less than a tenth of a milliliter and it
almost killed her.
In the usual annoying and insufferable way of finding Stan Lee a part, they shoe-horned him into this scene and re-wrote it a little but he didn't "hulk-out", it just made him very ill.
At the time of the report to the general it is very clear that he didn't die as the line in the script maintains that it almost killed him.
There is nothing in the movie to confirm that he died and the screenplay is quite clear about the womans fate at the time of the report.
