Anadrol vs. Halo...which is more toxic??

Which is more toxic...need some proof if possible...i have a bet with a friend of mine

Thanks

I would have to say anadrol,

ANADROL 50: The principal drawback to anadrol 50 is that it is a 17alpha alklated compound. Although this design gives it the ability to withstand oral administrtion, it can be very stressful to the liver. Cautious users will also limit the intake of this compound to no longer than 4-6 weeks and have there liver enzymes checked regularly by a doctor Kidney functions may also need to be looked after during long use, as water retention/high blood pressure can take a toll on the body, one should know Anadrol 50 the respect it is due. Its is a very powerful drug, but not always a friendly one
