Don't think they are comparable. Cypro is a direct serotonin receptor antagonist while I am not aware of any androgen actually being able to bind a serotonin receptor. Testosterone, progesterone and allopregnanolone may act as functional 5-HT3 antagonists but only there and indirectly. So, don't think cyproheptadine can be replaced reliably by any steroid.
