Nandrolone Phenylpropionate was developed in the 1950s
for the treatment of muscle atrophy and bone loss. The FDA approved it as a
short-acting form of Nandrolone that is released faster than the Decanoate.
Today, it is used to maintain muscle mass and accelerate recovery. PCT is
necessary, as it strongly suppresses endogenous testosterone production. It was
introduced in 1959 by Organon and remains a popular compound in the off-season.
