I did a cycle in Jan/feb and post cycle I lost a lot of size, most in fact. I did another cycle early summer, gained all the size back and then some, this time I used s4 in my post cycle and was amazed that I only lost the water weight from the test- it dropped overnight after test cleared my system. After that I didn't lose any muscle and even gained strength weeks after my cycle! I was only using 50 mg per day, 5 days per week. Now s4 is part of my pct/bridge. In fact, I believe that using s4 between my last and current cycle helped me maintain size so that I was able to hit 250 lbs for the first time ever this last cycle (night time weight after a meal

). What I'm saying is I still made gains on cycle after using s4 straight through.
