Time off AFTER PCT sounds more like it.
I actually experianced true "overtraining" after my last cycle. I kept killing it into pct and started waking up tired as F every day and sore as SHIT for days. If thats not overtrained I dont know what is.
That being said, my nutrition is NEVER what it should be. Honestly I eat like shit and IF I get enough calories in the day, alot of will come from fats(not good ones either)
I think with someone who is eating how they should be, it would be VERY hard to be "overtrained".
This is an exaggeration but you'll get the drift............THERE IS NO SUCH THING AS "OVER-TRAINING" just "UNDER-EATING!!!!"
now you can "over-train", but most likely.....your just under eating
