I have injected sustanon 250 for 4 weeks- 6 1ml ampules overall. But, I have decided not to run it longer: do I need to run some pct? Or the cycle is too short to need for a pct?
If I run a pct, though, are 3 weeks enough, to wait, before starting it (I heard, that undecanoate stays in human body even for 5 or 6 weeks)?
