First off time on=time off.
And second even if you dont do the full time off: I did an 8 week cycle, 3 weeks PCT of Clomid/Nolva and then I took two months off and started another cycle. Even that in reality wasnt long enough.
The Fact is your last test shot coincided with your Superdrol intake. And SD is not an "oral" persay in Gear talk. Your bodies natural test production was already down because you were injecting a foreign chemical into your blood stream via the muslce. Now as the test youve injected over 8 weeks tapers off, you've just ingested orally SD which will keep your body's HPTA down. Test keeps dwindling and still your body isnt producing its own test because you continue to ingest SD and inhibit the HPTA from kicking in. Next day, more SD...test levels drop further. You become lethargic, moody, develop acne, loose muscle mass.
Dude research your stuff. Eat right. come off right. pct. continue to train. Otherwise, its doing dumb stuff like that, that gives gear a bad name and messes peoples systems up.
If you're gonna "bridge" which it looked like you wanted to do, i think? Stick to DB not SD. IMO
