Out of curiosity, do you get no effect from other medicines too? Whatever you take - tadalafil, blood pressure, pain killers, anti inflammatory, modafinil... I'm not interested in experimenting with opioids and benzos, but those few times I have taken them after surgeries, my head have been spinning (oxycontin, tramadol, diazepam etc.)
As for oral steroids, I have no problems to feel that my biceps are harder (relaxed state, not pumped) after a week on superdrol or turinabol, it's not just in my head, my wife can feel it too. I wouldn't call it insane or such hyperboles, but it is easily noticeable.
