the nice benefit of this drug is that it does not hang around like deca. if you are in a precontest cycle, you can run it alot closer to the show, and not have to worry about it floating around when you need to be hard. same thing goes for when you come off cycle-- it will not stay around for 5 weeks at a level to low to give growth but high enough to shut you down.
for this reason i think it has a good place even when you are using deca. you can run deca early in the cycle, and then switch to the nandro phenprop later.
every 3rd day should be fine
there used to be a nandro cyp (syd?). that stuff was cool!
