NPP, like other anabolic steroids, can interfere with the body’s natural hormonal balance, potentially affecting fertility and reproductive health. While Nandro Phenylpropionate itself does not aromatize into estrogen as much as other steroids, it can still suppress the body’s natural testosterone production, which can lead to temporary infertility and reduced sperm quality. It is important to be aware of these potential effects and consider appropriate precautions, such as post-cycle therapy and consulting with a healthcare professional.
