My opinion is based off of my experience with dbol and that shit shuts you down pretty hard...i dont agree with using any dose in post cycle but especially not 30 to 40mgs plus
"Dosing of Dianabol is somewhat interesting, in that for most anabolic steroids it is a rather gray area as to what constitutes the maximum useful dose. In the case of Dianabol however, there has long been general agreement that while 50 mg/day is clearly more effective than anything substantially less, more than 50 mg/day adds nothing further, or nothing that can be noticed. This has been my own finding as well.
It is established that 50 mg/day Dianabol taken morning-only causes little HPTA suppression." - Bill Roberts
Since I'm guessing you never used it morning only and by itself, you're actually just basing your opinion from pure conjecture on your part. That would make me tend to believe the research. Also, I have used it only in the morning and by itself, and I tend to agree that it doesn't shut you down. The problem is, it doesn't give much in the way of gains either. If you are only using it to maintain while recovering, I think it may have some merit.
