Shelf Life

Hey guys,

    Havent posted in a while so probably only the oldest members around here will recognize me. 

Im going to finally be doing the First Cyle! next spring... Still kicking around different cycle ideas as I will be wanting to put on a lot of quality muscle, 3 on 4 off with stuff like test prop and primo (im getting really mixed info on the HL of primo) or test prop/nand phenyl OR go all out and do a test/eq long cycle (12 weeks). So if anyone has some advice opinion about it let me know. 
But to the real reason I posted... how long of a shelf life does this stuff have??  would getting it now if I can find a good source and storing it for 6-12 months be a problem??  Thanks again.
