I don't think it gets a bad report on this board at all, actually it gets a pretty good one.
Anytime you read or hear bad things about deca on any board, it's usually coming from those who do not properly use it, or from those who have heard of horror stories of deca use by others who did not properly use it.
I'm of the opinion that deca is one of the best substances we have to pick from, besides test it is by far my favorite AAS. Some might say that the only reason I say this is because I haven't experienced the negative sides only positive. This would be a true statement, but it's true because I use it the way it was intended.
