I've taken TREN EXTREME before and got some pretty good results, but it was kind of pricey. I recently just got a couple of bottles of TREN-250, which stated on the website was the same as TREN EXTREME, however upon receiving the bottle, I realized that the ingredients are slightly different on the TREN-250 bottle. It has Estra 4 9-Diene, which I think is the main ingredient in TREN EXTEME. Can anyone discipher this shit. It says that it contains 1 potent class steroidal compoud. Recommended dosage: 1 pill x2 daily. Where as Extreme TREN is 3 pills a day and TREN Extreme is 6 pills a day.
