This goes back to the debate of "various degrees of being shut down".... IMO, test will shut you down, tren will shut you down, etc. I don't believe there are various degrees of being shut down (though I think Nelson argues that Primo doesn't shut you down in the same way). The difference arises in recovery and that comes down to how long the compound remains active in your system. Obviously those with higher active lives will keep the body shut down longer.
Personally, I've used tren a bunch of times and didn't notice any harder recovery from that than say test. Deca is always a bitch to recover from, at least for me. Regardless of deca's active live, it can be detected for months after that, which I'm guessing is why people feel its after-effects for many months later.
