I used the old stuff to "jump" me back into the gym and I really liked it. As long as the new stuff is the same ingredients I'm sure itll be fine. Read on the site and check it out. Personally I used a knock off brand from ebay that was called E-STANE and i ran 45mgs a day for 4weeks. The gains were shocking. I packed on about 20 pounds but at least half of it was fat because I ate like garbage. However, the muscle gains have been almost entirely retained. You have to consider that I have not been lifting long enough to really lose gains yet though. I know the E-STANE was identical to epi accept the pills were 15mgs instead of 10 and they were roughly 40.00 shipped. Only drawbacks I had on it were that regardless of what people may say I lost a ****E load of hair. It regrew in almost a month but also I have baldness in my family. As far as PCT went I used an OTC PCT ASSIST ran liv-52 2 weeks before and throughout the cycle. I didn't have any trouble bouncing back at all and never really shut down a bit. It may have been a bit chancy to do this though and I'm keeping a real serm on hand if i run it again. I'll happily answer anything else as this is one pro hormone I know a decent amount about.
