old deca??

hey bros, ive got some old decas (Exp. 06 2005). Ive read that test wont go bad its just not concentrated as it was before the Exp. date, but is it the same for deca? (its deca from Norma Hellas).

I also got a multidose vial from a ugl lab, ive used it a couple of times about 8months to a 1year ago, is it also good ?? :scratch:

i would use the deca it should be fine, but as for the ugl lab stuff i wouldnt use it if its been open for a year.

is there a way to figure out the concentration of the decas???
