🧪 What is NTD 400?
NTD 400 is a fixed-ratio research-grade combination of three long-acting anabolic–androgenic steroids (AAS):
- Nandrolone Decanoate – 150 mg/ml
- Testosterone Enanthate – 150 mg/ml
- Drostanolone Enanthate – 100 mg/ml
All three compounds are esterified androgens designed for intramuscular depot release. After injection, esterases gradually cleave each ester, resulting in prolonged exposure suitable for in-vitro, ex-vivo or controlled in-vivo research models.
🔬 Key Research Details
| Parameter | Nandrolone decanoato | Testosterone Enanthate | Drostanolone Enanthate |
|---|---|---|---|
| Chemical Class | 19-nor testosterone derivative | Esterified endogenous androgen | DHT-derived non-aromatising androgen |
| Concentration in Blend | 150 mg/ml | 150 mg/ml | 100 mg/ml |
| Primary Receptor Target | Androgen receptor | Androgen receptor | Androgen receptor |
| Notable Features | Strong anabolic, low aromatisation, progestogenic behavior | Aromatises to estradiol; reference androgen | Non-aromatising; mild anti-estrogenic behavior |
🧬 Meccanismo d'azione
All components act as androgen receptor (AR) agonists. Once released from their esters, they bind intracellular ARs, migrate to the nucleus and regulate transcription of genes tied to:
- Protein synthesis
- Nitrogen retention
- Muscle fibre growth
- Erythropoiesis (RBC production)
- Bone and collagen metabolism
Nandrolone decanoato
Enhanced anabolic:androgenic ratio; weak aromatisation; studied for anemia, wasting, and bone density models.
Testosterone Enanthate
Long-acting aromatising androgen; foundational model for androgen + estrogen interactions.
Drostanolone Enanthate
Non-aromatising DHT-derivative; investigated for androgenic effects without estrogenic conversion.
📚 Research Overview
- Lean mass & strength: Increased muscle protein synthesis and fibre size in controlled models.
- Bone density: Effects on mineral density, osteoblast activity and collagen turnover.
- Erythropoiesis: Higher hemoglobin, hematocrit and reticulocyte counts.
- Endocrine suppression: Significant reductions in LH, FSH and endogenous testosterone.
- Mixed-androgen interaction: Useful in research comparing aromatising vs. non-aromatising androgens.
- Pharmacokinetic mapping: Modeling of staggered ester-release curves.
⚠️ Side Effects & Safety Considerations
(Based on class-wide AAS data; not specific to this product.)
- Endocrine: HPG-axis suppression, infertility, testicular atrophy.
- Androgenic: Acne, seborrhoea, hair loss, virilisation in females.
- Cardiovascular: ↓HDL, ↑LDL, BP elevation, thrombosis risk.
- Hepatic/Metabolic: Enzyme elevations, altered glucose and lipid metabolism.
- Neuropsychiatric: Mood swings, aggression, sleep disturbances.
- Gynecomastia: Driven primarily by testosterone aromatisation; nandrolone may contribute via estrogenic/progestogenic pathways.
- Local reactions: Irritation, swelling or infection if aseptic technique is not followed.
🛑 Compliance & Legal Status
- All components (nandrolone, testosterone esters, drostanolone) are controlled substances in many countries.
- Classified under WADA S1 Anabolic Agents — prohibited at all times.
- Supplied strictly as a research chemical by Royal Pharmaceuticals.
- Not approved for therapeutic, bodybuilding, or performance use.
