Sure, PCT might not work, but why take the chance? There have been studies done on long-term shut-down former steroid users who's natural test levels were restored to normal with PCT, so it's a good bet that it does work.
I would always go by the active life of the substance and run PCT the following times from the last administration of the drug:
Anadrol/Anapolan: 12 hours
Deca: 21 days
Dbol: 12 hours
EQ: 21 days
Fina: 3 days
Primo depot: 14 days
Sustanon: 18 days
Test Cyp: 18 days
Test Enan: 14 days
Test Prop: 3 days
Winstrol: 12 hours
I know a lot of you guys are saying leave a lot longer than this, and I'm not sure if it's a coincidence or not, but you guys leaving longer than the active lives are often the guys who are admitting to be hard recoverers. Hmmm go figure ;)
