I second this, used some tren Ace brewed in 2012 using gso, it was still potent with no pip or lumps/infection.Cooked and bottled it myself in 2010.... Just run a cycle in 2023.... Test P and NPP, zero issues with it, no infection and worked just fine!
You can believe it or not, its really meaningless to me. Just giving some real world experience's to dispel the "bro science".
I stored it in my bedroom closet away from any heat or extreme cold.
