Nandrolone Administration and Uses:
Nandrolone is entirely injectable, so if you want the muscle-building benefits, go with 300-600mg per week, 100mg 1-2 times per week for therapeutic, and 400mg per week max for performance enhancing.
For shorter, faster acting esters such as, Nandrolone Phenylpropionate (NPP), every other day injections are required at the least. 100-300mg injected three times per week will suffice, depending on goals and previous steroid usage experience.
Nandrolone should always be used in combination with a testosterone based anabolic steroid like Testosterone Enantahte or Testosterone Cypionate. This will ward off the low sex drive related side effects when endogenous testosterone is at hypogonadal levels (zero).
