What is Nandrolone Phenylpropionate (NPP)?
Nandrolone Phenylpropionate (NPP) made its debut in 1959 as the pioneering nandrolone ester in medical applications. Initially, it found its purpose in treating conditions like breast cancer and osteoporosis among women. Over time, it gained significant popularity in the realm of bodybuilding. Despite its historical prominence in medicine, its usage has waned, yielding ground to nandrolone decanoate (Deca Durabolin), a longer-acting and more user-friendly nandrolone variant. Nevertheless, both nandrolone esters remain highly favored within the bodybuilding community.
NPP distinguishes itself by its shorter half-life, approximately 4 days compared to Deca’s 14 days. Consequently, NPP necessitates more frequent injections to maintain stable blood serum levels. Notably, NPP stands out as one of the mildest androgenic steroids available, leaning towards the anabolic end relative to testosterone. Its anabolic/androgenic rating sits at 125/37, marked by limited estrogenic activity. Although both nandrolone and testosterone aromatize, nandrolone does so at a mere 20% of the rate seen in testosterone.
The advantages of NPP are manifold, encompassing enhanced endurance and recovery, heightened Red Blood Cell count, accelerated glycogen replenishment, reduced joint discomfort, elevated protein synthesis, nitrogen retention, and increased production of IGF-1. NPP also acts to inhibit cortisol, fosters collagen synthesis, bolsters bone mineral content, and facilitates the acquisition and preservation of lean muscle mass. Many assert that nandrolone esters rank among the most popular anabolic androgenic steroids (AAS) employed by bodybuilders and elite athletes aspiring to augment their physique and performance. This preference may be attributed to their relatively low propensity for androgenic and estrogenic side effects, rendering them suitable for both male and female athletes. Nonetheless, while NPP is less likely to induce masculinizing side effects such as hair loss, acne, voice deepening, or increased body/facial hair in women, female users must remain vigilant regarding potential virilization effects and discontinue usage promptly if symptoms manifest.
What Does NPP Stack Well With?
For men seeking optimized results, it is advisable to incorporate Nandrolone Phenylpropionate (NPP) alongside a foundational testosterone compound like Testosterone Enanthate, Testosterone Cypionate, or Sustanon, ideally in a ratio of approximately 60% testosterone to 40% NPP. To further enhance muscle size and strength gains, an oral anabolic steroid like Dianabol, Anadrol, Turinabol, or Anavar can be considered as a supplementary option. Given the inclusion of testosterone, it is strongly recommended to also include an anti-estrogen compound. There are no specific recommended stacks for females in this context.
Usage and Dosage
The optimal NPP dosage can vary significantly depending on different perspectives. In our view, a prudent dosage for most athletes typically falls within the range of 100-400mg per week for males, with a customary cycle duration of 8-12 weeks. It is advisable not to extend a cycle beyond 16 weeks. For female users aiming to minimize virilization effects, a maximum of 50mg per week for no more than 6 weeks is recommended.
To optimize benefits, users should consider dividing their weekly dose into 2-3 injections.
