Omnadec Drug Classification:
Analgesic; non-steroidal anti-inflammatory drug (nsaid)
Active substance: omnadec (naproxen)
Form: 400mg tablet
Active half-life: 12-15 hours
Dosage: adults 200-400mg twice daily after meals
Classification of Omnadec 400 mg 10 ml
Omnadec 400 mg 10 ml is classified as an anabolic-androgenic steroid (AAS) blend.
It contains multiple testosterone esters, typically Testosterone Decanoate, Testosterone Cypionate, Testosterone Phenylpropionate, and Testosterone Isocaproate, combined to deliver a sustained-release testosterone profile.
This injectable compound belongs to the androgen receptor agonist class, designed to elevate serum testosterone levels and promote muscle hypertrophy, strength, and recovery.
What is Omnadec 400 mg 10 ml?
Omnadec 400 mg 10 ml is a multi-ester testosterone solution produced by Rohm Labs, a pharmaceutical manufacturer known for high-purity performance formulations.
Each 10 ml vial delivers 400 mg of testosterone per ml, making it a concentrated, long-acting anabolic preparation favored during bulking and strength cycles.
The multi-ester design provides:
- Immediate release (short esters) for rapid onset
- Gradual, stable hormone delivery (long esters) for prolonged activity
This composition minimizes injection frequency while maintaining steady blood-testosterone levels.
Recommended Dosage for Omnadec 400 mg 10 ml
Dosage depends on experience, training goal, and hormonal tolerance.
| User Level | Recommended Weekly Dosage | Injection Frequency |
| Beginner | 400–500 mg | 1 injection per week |
| Intermediate | 600–800 mg | Split into 2 doses (3–4 days apart) |
| Advanced | 800–1,000 mg | 2 injections per week |
Typical cycle length: 10–14 weeks.
A post-cycle therapy (PCT) using SERMs such as Clomiphene Citrate or Tamoxifen Citrate is recommended once endogenous testosterone suppression occurs.
How Does Omnadec 400 mg 10 ml Work?
Once injected, the esterified testosterones undergo enzymatic hydrolysis, releasing free testosterone into the bloodstream.
The hormone binds to androgen receptors within muscle tissue, activating gene transcription responsible for:
- Increased protein synthesis
- Enhanced nitrogen retention
- Elevated red blood-cell (RBC) production
The result: greater muscle recovery, strength, and endurance.
Benefits of Taking Omnadec 400 mg 10 ml
Primary Physiological Benefits
- Accelerated muscle growth through amplified protein metabolism
- Increased strength output and neuromuscular efficiency
- Reduced muscle breakdown (anti-catabolic) under heavy training
- Improved red-blood-cell count, enhancing oxygen delivery
- Enhanced libido and mood stabilization via optimized testosterone levels
Performance Outcomes
- Noticeable strength gains within 3–4 weeks
- 3–6 kg lean-mass increase possible during 12-week cycles with proper nutrition
- Faster recovery between training sessions
When Should You Take Omnadec 400 mg 10 ml?
Because Omnadec contains multiple esters, its pharmacokinetic profile supports weekly or bi-weekly administration.
Injection schedule example:
- 1 ml (400 mg) on Monday and Thursday for a balanced release pattern.
Maintain consistent timing each week to ensure stable hormone concentrations.
Should You Not Take Omnadec 400 mg 10 ml?
Avoid Omnadec use if you have or are at risk for:
- Prostate or breast carcinoma
- Cardiovascular disease or hypertension
- Liver or kidney impairment
- Sleep apnea or cholesterol imbalance
It is not recommended for women, as even small doses can cause virilization effects (voice deepening, hair growth, etc.).
Mechanism of Omnadec 400 mg 10 ml
Omnadec’s mechanism mirrors endogenous testosterone function.
The hormone interacts with androgen receptor (AR) sites in muscle cells, initiating:
- mRNA transcription for contractile-protein synthesis
- Inhibition of glucocorticoid activity, reducing catabolism
- Enhanced IGF-1 expression, aiding muscle and bone density growth
- Stimulation of erythropoietin, increasing RBC count
This cascade produces sustained anabolic effects lasting up to 10 days post-injection due to the long esters like Decanoate and Cypionate.
Uses of Omnadec 400 mg 10 ml
Therapeutic Applications (Clinical Context)
- Treatment of androgen deficiency
- Hormone replacement therapy (HRT) in adult males
- Support for muscle wasting conditions
Athletic and Bodybuilding Contexts
- Bulking cycles for rapid lean-mass gain
- Stacking foundation compound with Deca-Durabolin, Dianabol, or Trenbolone
- Base testosterone in multi-compound stacks
Warnings and Precautions for Omnadec 400 mg 10 ml
- Do not exceed recommended dosage to avoid estrogenic and cardiovascular stress.
- Periodic liver function and lipid profile tests are advised.
- Aromatase inhibitors (AIs) such as Anastrozole may be used to control estrogen-related side effects.
- Inject intramuscularly (IM) only into gluteal muscles under sterile conditions.
- Rotate injection sites to prevent tissue irritation or abscess formation.
Side Effects of Omnadec 400 mg 10 ml
Like all testosterone esters, potential side effects include:
Estrogenic Effects
- Gynecomastia (male breast tissue growth)
- Water retention and bloating
- Elevated blood pressure
Androgenic Effects
- Acne and oily skin
- Accelerated hair loss in predisposed men
- Increased body hair growth
Metabolic and Hormonal Effects
- Natural testosterone suppression
- Altered cholesterol ratios (HDL ↓ / LDL ↑)
- Mood swings or aggression (“roid rage”)
Mitigation Tips
- Employ on-cycle support supplements (e.g., milk thistle, omega-3s).
- Follow PCT protocols after the cycle to restore endogenous hormone balance.
Storage for Omnadec 400 mg 10 ml
To maintain potency and sterility:
- Store at room temperature (15–25 °C).
- Keep away from direct light and moisture.
- Do not refrigerate or freeze.
