Shelf life on opened PH's

[protein24]

I know that unopened bottles have a shelf life of several years but what about opened ones. The reason I ask is because my younger brother got into a bottle of my original super dmz(superdrol & DMZ). Didn't take anything thank god said he just wanted to smell them, dumbass. haha anyway i wasn't plan on using this any time if i save it for a year or two should it still be good? thanks

Should still be good bro. Opened or not. So long as you have them stored in a cool dark place. Epi is the only one that is said to degrade within 6 months of being opened.
