That's right I was already tapped into the 2nd bottle. I've had this Tren in my stock pile for about 3 years from a domestic source I've been using for over 10 years.. Used Tren para/hex, E plenty of x's thru-out the years. Sure there were sides and were tolerable. I read your question, but has nothing to do with the sides intensifying the longer your on it. Don't know if you ever done Ace, but I'm sure you've read posts how the sides were too much and had to get off and posts because of the side will never use the stuff again..
