Some bodybuilders and athletes use trenbolone for its muscle-building and otherwise performance-enhancing effects. [ citation needed ] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone as a Schedule III controlled substance under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , metenolone , and trenbolone. 
Dawkins thinks it odd that Christians don’t look eagerly forward to death, given that they will thereby be ushered into paradise. He does not see that Christianity, like most religious faiths, values human life deeply, which is why the martyr differs from the suicide. The suicide abandons life because it has become worthless; the martyr surrenders his or her most precious possession for the ultimate well-being of others. This act of self-giving is generally known as sacrifice, a word that has unjustly accrued all sorts of politically incorrect implications. Jesus, Dawkins speculates, might have desired his own betrayal and death, a case the New Testament writers deliberately seek to rebuff by including the Gethsemane scene, in which Jesus is clearly panicking at the prospect of his impending execution. They also put words into his mouth when he is on the cross to make much the same point. Jesus did not die because he was mad or masochistic, but because the Roman state and its assorted local lackeys and running dogs took fright at his message of love, mercy and justice, as well as at his enormous popularity with the poor, and did away with him to forestall a mass uprising in a highly volatile political situation. Several of Jesus’ close comrades were probably Zealots, members of an anti-imperialist underground movement. Judas’ surname suggests that he may have been one of them, which makes his treachery rather more intelligible: perhaps he sold out his leader in bitter disenchantment, recognising that he was not, after all, the Messiah. Messiahs are not born in poverty; they do not spurn weapons of destruction; and they tend to ride into the national capital in bullet-proof limousines with police outriders, not on a donkey.
In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields.  In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system.  The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position.  In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.
