For darkroom users, I highly recommend to obtain glut in 2.5% or lower
concentrations, preferrably in acidified solution of pH 4 or
below. Don't try to save pennies by buying more concentrated stuff and
dilute them yourself.

I routinely handle 25% stock of glut, but when I touch that stuff, the
glut stock is refrigerated very cold to minimize the fume, but still I
use a face mask for transporting the bottles, and work in a fume hood
until the stock is diluted. If you are not set up properly, I'd pay a
few extra bucks to buy a ready-to-use stocks.
