i was having a discussion with my friend about a deca durabolin cycle. he says its ok to have a deca only cycle. i showed him the profile of anthony roberts about deca. and he disagrees with it and says: on the graph on anthony roberts profile of deca durabolin its Phenylpropionate? he says this substance has a half life of a few days and deca durabolin has a half life of 2 weeks. if you shot 100mg of deca in 2 weeks 50mg would be active. how exactly is that going to shut you down in one day...?
