Currently into week 6 of EQ 400/wk. and Test E 375/wk., both Stealth. So far have gained 6 lbs., virtually no retention, strength increase decent. My endurance is through the roof. It is only just barely kicking in. Very slow cycle. Planned on going 16 weeks, now leaning toward 20 if all is well. It is most definately the real deal, and the price just can't be beat. Also, my brother is on identical cycle, has made slightly better strength and weight gains, but is quite a bit smaller than me to begin with. Both pretty happy so far.
