Boldenone Undecylenate — Equipoise 500 by Dragon Pharma
Equipoise 500 is Dragon Pharma's high-concentration formulation of injectable Boldenone Undecylenate at 500mg/ml — the same active substance and ester as EQ 300, at a significantly higher concentration for advanced users running higher weekly doses across extended 14-16 week cycles. Each 10ml vial in Dragon Pharma's MCT oil carrier delivers the same compound at a concentration that meaningfully reduces injection volume at higher weekly doses.

What Is Equipoise 500?
Equipoise 500 contains Boldenone Undecylenate — structurally testosterone with a C1-C2 double bond, producing a compound with approximately 50% of testosterone's androgenic activity, 50% of its aromatisation rate, and significantly stronger erythropoietic (RBC-stimulating) effects. The 500mg/ml concentration is the only meaningful difference from EQ 300 — the same extended 14-day half-life, the same cycle length requirements and the same monitoring considerations apply. For full compound background, see the EQ 300 product page.
Why Higher Concentration Matters for Long EQ Cycles
The practical case for Equipoise 500 over EQ 300 is more compelling for Boldenone than for most other compounds, specifically because of EQ's cycle length requirements:
- A 16-week EQ cycle at 600mg/week requires 9.6ml per week at 300mg/ml vs 1.2ml per week at 500mg/ml — a 5× reduction in volume per injection
- Over a full 16-week cycle, this translates to a significantly lower total injection volume and fewer injection site rotations
- EQ is already one of the more viscous injectable compounds — at 500mg/ml in MCT oil, warming the vial before drawing is particularly important to maintain flowability
Effects and Benefits
- Steady lean mass gains with lower water retention than testosterone at equivalent doses
- Pronounced appetite stimulation — one of the strongest of any AAS, useful in caloric surplus phases
- Improved endurance and work capacity through RBC/haematocrit elevation
- High concentration reduces injection volume across extended 14-16 week protocols
- Lower androgenic activity and aromatisation rate than testosterone
Dosage and Administration
| Weekly Dose | Volume at EQ 300 | Volume at Equipoise 500 | Volume Saved |
|---|---|---|---|
| 300 mg/week | 1 ml | 0.6 ml | 0.4 ml/week |
| 600 mg/week | 2 ml | 1.2 ml | 0.8 ml/week |
| 1000 mg/week | 3.3 ml | 2 ml | 1.3 ml/week |
Weekly doses are split into 2 injections to maintain more stable blood levels despite the long half-life. Due to the high concentration, warming the vial gently before drawing is recommended to improve viscosity and reduce injection site discomfort.
Side Effects
- Haematocrit elevation — same concern as EQ 300, requiring periodic bloodwork; more pronounced at higher weekly doses possible with this concentration
- Suppression of natural testosterone — Post Cycle Therapy required; start PCT 3-4 weeks after last injection due to EQ's long ester
- Aromatisation at 50% testosterone rate — estrogen management may be needed via Arimidex at higher doses
- Pronounced appetite — a benefit for bulking but potentially counterproductive for cutting
- Higher concentration may increase post-injection discomfort compared to EQ 300
Equipoise 500 vs EQ 300
- Equipoise 500 (500mg/ml) — for advanced users running 600mg/week and above across long cycles, minimising injection volume
- EQ 300 (300mg/ml) — for most users, easier dosing precision at standard weekly amounts
Building a Cycle Around Equipoise 500
- Enantat 400 for matched high-concentration testosterone base
- Deca 300 for mass-focused cycles — Boldenone and Nandrolone pair well with different mechanisms
- Arimidex for estrogen management at higher doses
- Clomid or Nolvadex for Post Cycle Therapy
"Equipoise 500 delivers Boldenone Undecylenate at a concentration designed for extended high-dose protocols, reducing the injection volume burden across the long cycles this compound requires to reach its full potential."
Storage and Handling
Store Equipoise 500 at room temperature away from direct sunlight. Due to its higher concentration, warm the vial gently before drawing to improve viscosity. Use sterile technique for every draw.
