[AMG]

Has anybody ever used injectable Metribolone or Dimethylnandrolone my friend just let me have to vials one of each and told me that he was getting masive strength and gains of of the two and a little test he says that it has given more strength and size then a tren and Dbol or Anadrol cycle. Does anyone have any knowledge on either of these?
