I'm a PL'er so i track my strength gains very very closely.
I finished a Test Prop / Var cycle almost exactly 3 weeks ago.
I increased my total (sq/bench/DL) by exactly 110lbs over the course of the cycle.
Ive kept around 70% of those strength gains at this moment in time, a net increase of 75lbs on my total due mainly to the cycle.
As long as i dont lose any more in this last week of pct i will be pretty happy with that. I would say most of the strength is down to the Var as when i ran test p only i got a lot less gains strength wise.
