NPP/Nandrolone PhenylPropionate：Lean Muscle Gainer&Anti-Muscle Loss

$85.00

Nandrolone Phenylpropionate (NPP) is an anabolic-androgenic steroid (AAS) derived from testosterone. It is a short-ester version of Nandrolone, designed for faster absorption and a shorter half-life than its longer-ester counterpart, Nandrolone Decanoate (Deca-Durabolin). First developed in the late 1950s, NPP was used medically for muscle wasting, anemia, and osteoporosis. Today, it remains a compound of interest in both clinical and performance enhancement contexts.

Characteristics

Property Details
Molecular Formula C₂₇H₃₄O₃
Molecular Weight 406.57g/mol
CAS Number 62-90-8
Appearance Yellow to off-yellow Oil Injection

NPP binds to androgen receptors in muscle tissue, triggering an increase in protein synthesis, nitrogen retention, and red blood cell production. Its anabolic effects are higher than its androgenic effects, making it popular for building lean mass without excessive androgenic side effects like severe acne or hair loss (though these risks still exist).

Because of the phenylpropionate ester, the compound enters the bloodstream quickly after injection but also clears relatively fast—requiring more frequent dosing compared to Deca-Durabolin.

Benefits

When used under proper guidance, NPP may offer:

  • Lean muscle gain with minimal water retention compared to some other steroids.
  • Improved recovery from intense training sessions.
  • Increased joint comfort due to collagen synthesis and synovial fluid enhancement.
  • Enhanced endurance from elevated red blood cell count.
  • Reduced muscle wasting in medical scenarios.

Common Uses

Medical Uses

  • Primary: Treatment of advanced breast cancer in women
  • Adjunct therapy: Management of senile or postmenopausal osteoporosis in women
  • Proposed (recent): Androgen replacement therapy for men with androgen deficiency (due to high anabolic-androgenic ratio, lower risk of prostate issues and hair loss vs. testosterone)

 

Non-Medical Uses

  • Physique enhancement: Used by bodybuilders for muscle growth and body composition improvement
  • Performance enhancement: Utilized by competitive athletes and powerlifters to boost athletic performance
  • Popularity driver: High anabolic-androgenic ratio + weak propensity for androgenic/estrogenic side effects (making it a top choice among AAS users)

Possible Side Effects

Like all anabolic steroids, NPP can cause serious health risks if misused or taken without medical supervision:

  • Estrogenic side effects (water retention, gynecomastia) due to aromatization into estrogen.
  • Androgenic side effects (acne, hair thinning, body hair growth) depending on genetic sensitivity.
  • Suppression of natural testosterone production leading to hormonal imbalance.
  • Cardiovascular strain (negative changes in cholesterol levels, increased blood pressure).
  • Liver strain is minimal compared to oral steroids, but still possible with long-term high-dose use.
