Equipoise, also known as Boldenone, is a powerful anabolic steroid originally developed for veterinary use—most notably in horses. Today, it’s popular among bodybuilders and athletes for its lean muscle building, increased vascularity, and strength-enhancing properties.
Boldenone comes in two main esters:
- Boldenone Undecylenate (long-acting)
- Boldenone Propionate (short-acting)
Let’s break down everything you need to know about these two forms of Boldenone—and whether it fits your performance goals.
🔍 What Is Boldenone Undecylenate?
- Long ester (injectable oil-based)
- Known as Equipoise (EQ)
- Half-life: ~14 days
- Injected 1–2 times per week
- Slow and steady gains in lean mass, appetite, and vascularity

🔥 What Is Boldenone Propionate?
- Short ester
- Half-life: ~2–3 days
- Injected every other day or daily
- Faster acting, potentially more painful injections
- Quicker results but more frequent administration

💪 Benefits of Boldenone (Both Esters)
- Promotes lean muscle growth
- Enhances vascularity without extreme water retention
- Increases red blood cell count for better endurance
- Improves appetite (great for bulking phases)
- Mild androgenic effects = lower chance of hair loss, acne (compared to Tren/Test)
📆 What’s a Safe Boldenone Cycle?
🔹 For Boldenone Undecylenate:
- Beginner: 300–400 mg/week (12–14 weeks)
- Intermediate: 500–600 mg/week (12–16 weeks)
- Advanced: 700–800 mg/week (can stack with Test E or Deca)
🔹 For Boldenone Propionate:
- 100–150 mg every other day
- Cycle length: 8–10 weeks
- Often used in cutting or lean bulking stacks

❓ Common Questions Answered
1. What Results Can I Expect from Equipoise?
- 8–15 lbs of lean mass gains (over 12–14 weeks)
- Dry, hard muscle look with added vascularity
- Noticeable increase in appetite and recovery
2. Does Boldenone Cause Side Effects?
Yes, although it’s milder than many steroids:
- Mild estrogenic activity (rarely causes gynecomastia)
- Possible increased blood pressure or RBC count
- Acne or oily skin in some users
- Aggression in high doses
Boldenone is generally well-tolerated with smart dosing.
3. Do I Need PCT After Equipoise?
Absolutely. Post Cycle Therapy helps restore natural testosterone.
- Use Clomid or Nolvadex for 3–4 weeks
- Begin 2–3 weeks after last injection of Undecylenate
- Begin 3–5 days after last Propionate shot
4. Can Women Use Equipoise?
Not recommended. Due to strong anabolic nature, virilization risk is high (deep voice, body hair, etc.)
5. Can You Stack Boldenone?
Yes. Common stacks include:
- Boldenone + Testosterone Enanthate (bulking)
- Boldenone + Winstrol (cutting/vascularity)
- Boldenone + Trenbolone (recomp, strength)
Always match ester length when stacking for smooth levels.
6. How Often Should I Inject Boldenone?
- Undecylenate: Every 5–7 days
- Propionate: Every 1–2 days
7. Is Boldenone Legal?
In most countries, Boldenone is a controlled substance, only available with a prescription. However, underground labs and research chemical suppliers often carry it for “research purposes.”
📊 Who Should Use Boldenone?
✅ Ideal for:
- Intermediate to advanced users
- Looking for slow, quality muscle gains
- Cutting without water retention
- Enhancing appetite and endurance
❌ Not ideal for:
- Complete beginners
- Women
- Users wanting rapid mass like with Dianabol or Anadrol
📈 Conclusion: Is Equipoise Worth It?
Equipoise (Boldenone) is one of the most underrated steroids for building lean muscle mass with minimal side effects. Whether you choose Undecylenate for long cycles or Propionate for faster action, it delivers dry, vascular gains that are easier to keep post-cycle.
Stack it smart, use proper PCT, and respect its long half-life—especially with Undecylenate.
