Mr. Laredo is on the money but I have to say I really liked Tornel's Sust & Test-E -- no pain from either, gains from both but the Sust made my back break out like crazy... Go figure.
QV is my favorite. I also like Animal Power, Denkall, and Tornel for their test E. The T-200 is a great buy even if it's underdosed, it's cheap to use a larger amount.
