My gut feeling is they put it in their for the same reason most use it in PCT and that's a libido boost. It's shutdown is only mild...but hey, let's be honest, I'd not pay much attention to what underground labs which are really just people brewing in their bathtub do or take that as gospel. Ok I'm sure they have half decent 'set ups' But you will forgive me for not taking the word of drug dealers on the what/how a drug should be used lol. I'd rather go on scientific research. As for my case being in the minority, very possible however everyone's experience with medication will vary from user to user so it's a given some won't be suppressed and others will. The thing with proviron is its testosterone suppression is minimal/not significant and that is documented in scientific reports. If one is trying to recover then I don't see why they would risk prolonging that process with the addition of and androgen. Each to their own.
