This is a 2 part question relating to IBE Epistane that i have not been able to get a clear awnser on through my hours and hours of google searching so far. While doing research on Epistane i came across several different discussions about shelf-life of Epi. Could anyone here clarify what the actual shelf-life is? I got my hands on a couple bottles with an expiration date of 4/13 so i was figuring i was ok but then i started to debate how i was going to dose it, if it truely has a short shelf-life then i would run it @ 40 straight through, if not then i was thinking of pulsing @ 60 every other day so i could run the cycle a little longer, also any ideas on the half-life on Epi? Most discussions conclude that half-life is 6-8 hours but any info would be appreciated.
