Gp Mhn and tren combine in the same cycle?

MOHN (Methylhydroxynandrolone) is an orally derived version of nandrolone.

So does that mean that MOHN is a 19-nor compound and shouldn't be stacked with tren which is a 19-nor compound?

I have read that the compound MOHN is converts to a DHT compound (such ad anavar, winny)once digested. I don't know how much truth this is. Can an oral change its properties once digested?

Can anyone shed some light on this.

Thank guys
