Nandrolone Phenylpropionate (NPP) is a fast-acting anabolic steroid popular in bodybuilding for its ability to promote significant muscle growth and enhance recovery. It is often used in bulking cycles to help athletes and bodybuilders gain lean muscle mass efficiently.

Recommended Dosage
The ideal dosage of NPP for muscle growth typically ranges between 300-500 mg per week for men, administered in 2-3 injections per week to maintain stable blood levels. For beginners, starting at the lower end of this range is advisable to assess tolerance and minimize potential side effects. Advanced users may push the dosage to the higher end, but exceeding this can increase the risk of side effects. For women, a lower dosage of 50-100 mg per week is recommended due to the risk of virilization.

Cycle Duration
A typical NPP cycle lasts 8-12 weeks, depending on goals and experience level. It's often stacked with other compounds like Testosterone to maximize results. As with all steroids, proper Post-Cycle Therapy (PCT) is necessary to restore natural hormone production after the cycle.
