Enanthate 400 by Dragon Pharma
What Is Enanthate 400?
Enanthate 400 is Dragon Pharma testosterone enanthate concentrated at 400 mg per mL - 4,000 mg in one 10 mL vial. The hormone, ester and effects are identical to the classic Enanthate 250; only the concentration is higher.
The point of 400 mg/mL is practical: a full cycle base in fewer vials and smaller injections. Half a mL already delivers 200 mg, so a 500 mg weekly dose is just 0.6 mL twice a week. It is aimed at experienced users who know their dose; beginners are usually better served by the 250 mg/mL version.
At 400 mg/mL the dosing math is simple: 0.5 mL equals 200 mg, 1 mL equals 400 mg. The standard 500 mg per week is about 0.6 mL twice a week.
| Weekly Dose | Per Injection (2x / week) | One Vial Lasts |
|---|---|---|
| 400 mg | 0.5 mL | 10 weeks |
| 500 mg Most common | 0.6 mL | 8 weeks |
| 600 mg | 0.75 mL | 6.5 weeks |
| 750 mg | 0.9 mL | 5.5 weeks |
Doses are small, so use a 1 mL or 3 mL syringe with fine markings - precision matters more at 400 mg/mL than at 250 mg/mL. A typical cycle runs 12-16 weeks.
Enanthate 400 is a high-dose testosterone base. Every partner below is from the same Dragon Pharma line, so the whole cycle comes from one source.
| Stack | Goal |
|---|---|
| Enanthate 400 + Deca 500 | Big mass cycle |
| Enanthate 400 + EQ 300 | Quality mass, endurance |
| Enanthate 400 + Anavar 10 | Strength and hardness |
| Enanthate 400 + Masteron 100 | Dry, conditioned look |
Prefer standard 250 mg/mL for easier dose control? See Enanthate 250 or Cypionat 250.
At higher doses the estrogen load is higher too, so control matters. Testosterone aromatizes: keep an aromatase inhibitor on hand, watch for water retention and confirm with bloodwork.
- Suppression - natural production shuts down on cycle; PCT is required.
- Estrogen sides - water retention, mood swings, sensitive nipples; manage with an AI.
- Hair and skin - possible in genetically prone people.
- Bloodwork - testosterone, estradiol, hematocrit, lipids mid-cycle.

This one hits hard. Running 400/week and strength went up fast, especially on bench and deadlift. Oil is a bit thick so I warm it up before pinning, after that no issues. Ordered through GASProids, came well packed in about 17 days.

High concentration is no joke, definitely stronger than lower dosed versions I’ve tried. Had some PIP at first but mixing it with another oil solved it. Gains are clean and steady. Delivery was smooth and discreet.
Who is Enantat 400 best suited for?
It's typically chosen by experienced athletes running advanced mass or strength cycles.
Is this mainly a bulking compound?
Yes, it's most often used for size and power, though some run it in lean gain phases.
Can it be used as a test base?
Yes, it's commonly used as the primary testosterone foundation in many advanced stacks.
Does it require anti-aroma support?
Many users include one, as testosterone can convert to estrogen.
Is this better than lower-dose versions?
It offers more hormone per milliliter, which some athletes prefer for high-demand cycles.
What is Dragon Pharma Enanthate 400?
Enanthate 400 is Dragon Pharma's high-concentration testosterone enanthate - 400 mg per mL in MCT oil, 4,000 mg per 10 mL vial. Same ester and effects as standard enanthate, but more mg per vial and smaller injection volumes.
Enanthate 400 or Enanthate 250 - which should I buy?
Both contain the same testosterone enanthate. Enanthate 250 is better for beginners and moderate doses; Enanthate 400 suits experienced users who want 4,000 mg per vial and less volume per injection at higher weekly doses.
How much Enanthate 400 should I take per week?
At 400 mg/mL, 0.5 mL equals 200 mg. The most common protocol is 500 mg per week - about 0.6 mL twice a week. Beginners should usually start with the 250 mg/mL version instead.
How often do I inject Enanthate 400?
Twice a week, like all long-ester testosterones. The half-life is about 7 days, so two evenly spaced injections keep levels stable.
How long does one vial of Enanthate 400 last?
One 10 mL vial holds 4,000 mg. At 500 mg per week it lasts about 8 weeks; at 400 mg per week about 10 weeks.
Is Enanthate 400 more painful to inject than Enanthate 250?
Higher mg/mL oils are often slightly thicker, which can feel a bit more noticeable at the injection site. Dragon Pharma uses MCT oil, which keeps this manageable - inject slowly and rotate sites.
When should I start PCT after Enanthate 400?
About 2 weeks after the last injection - the enanthate ester clears slowly. Standard PCT uses SERMs such as clomiphene or tamoxifen.
Does Enanthate 400 cause estrogen side effects?
Yes - testosterone aromatizes into estrogen at any concentration. Keep an aromatase inhibitor on hand and confirm estrogen management with bloodwork.
Is Enanthate 400 lab tested?
Yes. This listing was third-party lab tested at 418.88 mg/mL - 104.7% of the 400 mg/mL label claim. Check the batch on your vial against the published report.
Can beginners use Enanthate 400?
Not recommended as a first product - the high concentration makes dose control harder for someone new. Beginners are better served by Enanthate 250 or Cypionat 250 at standard 250 mg/mL.
