Testosterone Enanthate — Enantat 400 by Dragon Pharma
Enantat 400 is Dragon Pharma's high-concentration formulation of injectable Testosterone Enanthate — the same active substance and ester as Enantat 250, delivered at 400mg/ml instead of 250mg/ml. Each 10ml vial in Dragon Pharma's MCT oil carrier provides a more concentrated hormonal load, allowing advanced users to reach higher weekly doses with fewer total injections or smaller injection volumes.

What Is Enantat 400?
Enantat 400 contains Testosterone Enanthate — the same long-acting ester used in Enantat 250 — at a higher 400mg/ml concentration. The pharmacology is identical to standard Testosterone Enanthate: the enanthate ester extends the hormone's release over approximately 7-8 days, with the same anabolic and androgenic activity as any other testosterone ester. The only practical difference between Enantat 400 and Enantat 250 is concentration — at 400mg/ml, a given dose is delivered in less than two-thirds the injection volume required by the 250mg/ml version.
Effects and Benefits
- Substantial increases in muscle mass and strength when paired with adequate training and nutrition
- Improved recovery between training sessions and reduced cumulative fatigue across a cycle
- High concentration allows higher weekly doses without proportionally larger injection volumes
- Fewer total injections required for the same weekly dose compared to lower-concentration testosterone
- Serves as the base compound supporting every other compound added to a cycle
Dosage and Administration
| Use Case | Typical Dose | Frequency |
|---|---|---|
| Standard cycle (intermediate) | 300–500 mg/week | Weekly, split into 2 injections |
| Advanced cycle | 500–1000 mg/week | Weekly, split into 2 injections |
| High-dose advanced protocols | 1000 mg/week and above | Weekly, split into 2 injections |
With the same ~7-8 day half-life as standard Testosterone Enanthate, Enantat 400 is dosed on the same twice-weekly schedule. The practical advantage of the 400mg/ml concentration becomes apparent at higher weekly doses — for example, a 1000mg/week protocol requires 2.5ml total per week at 400mg/ml versus 4ml at 250mg/ml, reducing injection volume and the number of injection sites needed.
Side Effects
Enantat 400 carries the same side effect profile as any Testosterone Enanthate product — concentration does not change the pharmacology, only the dose-per-ml:
- Water retention and potential gynecomastia at higher doses — managed with an aromatase inhibitor such as Arimidex or Aromasin if needed
- Suppression of natural testosterone production — requires Post Cycle Therapy after the cycle
- Possible elevation of blood pressure and red blood cell count — routine bloodwork is recommended throughout use, particularly at higher weekly doses
- Increased post-injection discomfort at the injection site due to the higher concentration, more so than with 250mg/ml formulations
Enantat 400 vs Enantat 250
Dragon Pharma offers Testosterone Enanthate in two concentrations:
- Enantat 400 (400mg/ml) — for advanced users running higher weekly doses who want to minimise injection volume
- Enantat 250 (250mg/ml) — the standard concentration, suited to most users and easier to dose precisely at lower weekly amounts
The active substance and effects are identical between the two — the choice comes down to weekly dose and injection volume preference. Users running 300-500mg/week often find Enantat 250 more practical for dose precision, while those running 750mg/week and above benefit from Enantat 400's reduced injection volume.
Building a Cycle Around Enantat 400
As a high-concentration testosterone base, Enantat 400 pairs with:
- Deca 500 for high-dose mass cycles requiring matched injection efficiency
- Equipoise 500 for lean mass cycles at advanced dose ranges
- Anavar 50 for added strength and definition in advanced protocols
- Clomid or Nolvadex for Post Cycle Therapy
"Enantat 400 is formulated to the same MCT oil standard as our other testosterone products, simply at a higher concentration. It gives advanced users the ability to run higher weekly doses without a proportional increase in injection volume."
Storage and Handling
Store Enantat 400 at room temperature, away from direct sunlight and heat. Due to its higher concentration, warming the vial gently before drawing can help with viscosity and reduce injection discomfort. Use sterile technique for every draw.
