I think many feel pretty damn good on it too, so I don't know where the "feel like shit" comes from.
Even if it doesn't agree with you you can't say it isn't effective as far as orals go. This "anti Dianabol" movement is all due to Victor Black, who said it goes in the trash lol. If just one top influencer/trainer said it's a great steroid you'd suddenly see many say how great it is lol. No one uses it in prep either, but it could work great, like any steroid could, even if supposedly a "wet" compound, Anadrol, Test, it can all be used.
