Scientific Overview

Nandro F 150 contains nandrolone phenylpropionate (NPP), a short/medium-acting ester of nandrolone.

Nandrolone is a 19-nor testosterone derivative with a strong anabolic profile and moderate androgenic activity in laboratory models.

NPP’s faster ester kinetics make it suitable for experiments requiring tighter timing, repeated exposures, or controlled pharmacokinetic curves compared with long esters like decanoate.

This compound is widely used in research on muscle protein metabolism, nitrogen balance, bone density, connective-tissue repair, and endocrine suppression.

Nandrolone and all its esters are prohibited anabolic agents under WADA rules.

Key Research Details

• Ester: Phenylpropionate — short/medium half-life
• Strength: 150 mg/ml
• Form: Oil-based injectable for IM research use

Laboratory Research Themes:

• Anabolic vs. androgenic signaling
• Nitrogen retention & protein turnover
• Muscle mass, strength, and anabolic modeling
• Bone mineral density & collagen synthesis
• Endocrine suppression & HPG-axis studies
• Short-acting AAS pharmacokinetics

WADA Status: Prohibited at all times (S1 Anabolic Agents)

Mechanism of Action

Androgen Receptor Binding

Nandrolone phenylpropionate is hydrolysed to free nandrolone after injection. Nandrolone binds the androgen receptor (AR), initiating transcription of genes involved in protein synthesis, nitrogen retention, muscle hypertrophy, and erythropoiesis.

Reduced Aromatisation & 5- Reduction

Compared with testosterone, nandrolone aromatises less and is reduced to a weaker androgen (DHN), influencing androgenic outcomes in tissues such as the prostate, skin, and scalp.

Metabolic & Hematologic Effects

Nandrolone influences lipid metabolism, bone turnover, glucose handling, and red-blood-cell production—contributing to its use in hematology and osteoporosis research.

Research Overview

Research Area

Typical Findings

Muscle wasting & cachexia

Improved lean mass, strength, and nitrogen balance; endocrine suppression as a trade-off.

Bone density

Increased BMD and improved collagen structure in glucocorticoid-induced models.

Erythropoiesis

Elevated hemoglobin/hematocrit via EPO stimulation.

HPG-axis impact

Suppressed LH, FSH, and endogenous testosterone with dose-dependent recovery delays.

Cardiometabolic markers

Reduced HDL, increased LDL, blood pressure changes in longer-term exposure models.

These outcomes are observed in clinical and preclinical research; not recommendations for human enhancement.

Potential Research-Level Applications

• Lean mass and skeletal muscle anabolism models
• Joint and connective-tissue research (collagen, tendon, cartilage)
• Bone-density and osteoporosis exploration
• Hematology and erythropoietic studies
• Short-ester pharmacokinetic modeling

Applies only to controlled laboratory environments.

Known Side Effects & Safety Considerations

• Endocrine suppression: LH/FSH inhibition, lowered natural testosterone, infertility in male models
• Cardiovascular: Decreased HDL, increased LDL, BP elevations, thrombosis risk
• Hepatic/Renal: Possible liver enzyme elevation; renal strain at high exposure
• Androgenic: Acne, oily skin, hair loss, virilisation effects in females
• Estrogenic & Progestogenic: Potential water retention or gynecomastia mechanisms
• Neuropsychiatric: Mood changes, irritability, libido changes

These effects are identified in AAS research literature and do not serve as guidance for human administration.

Compliance & Legal Status

Classified as an anabolic agent under WADA S1 — prohibited at all times.

Controlled/prescription-only substance in many jurisdictions (EU/UK/US).

Supplied strictly as a research chemical by Royal Pharmaceuticals.

Not approved by EMA, MHRA, FDA, or similar authorities.
