Boldenone 300mg/ml (Equipoise)
Boldenone Undecylenate, commonly known as Equipoise, is a long-acting injectable steroid used for steady muscle gain, strength and longer bodybuilding cycles. It is a popular choice for users who want gradual, quality gains rather than rapid changes in bodyweight.
Each 1ml contains 300mg of Boldenone Undecylenate. Each 10ml bottle contains 3,000mg total.

Long-ester cycle
Boldenone is a long-acting injectable. Most cycles run 12–16 weeks so the compound has enough time to build up and produce steady results.
| Weekly Dose | Volume at 300mg/ml |
|---|---|
| 300mg | 1ml per week |
| 400mg | 1.33ml per week |
| 600mg | 2ml per week |
| 800mg | 2.67ml per week |
Steady muscle gain
What Boldenone Is Best Used For
Boldenone is mainly used for lean muscle, strength and gradual size gains. The gains are usually slower than with compounds such as Dianabol or Anadrol, which is why Boldenone is normally used in longer cycles.
It works particularly well when the goal is to keep building over time without relying on a short, aggressive cycle.
Appetite
Boldenone & Appetite
Many users notice an increase in appetite while using Boldenone. This can be useful during a bulking phase when eating enough calories every day becomes difficult.
Boldenone has also been described in published steroid research as having appetite-stimulating effects.[2]
Long-acting injectable
Why Boldenone Is Used for Longer Cycles
Boldenone Undecylenate uses a long ester, so it releases gradually after injection and remains active much longer than short-ester compounds.
This makes Boldenone well suited to longer bodybuilding cycles where the aim is steady progress over several months rather than fast changes over a few weeks.
Published pharmacokinetic research also confirms the prolonged release and persistence of Boldenone Undecylenate after intramuscular injection.[1]
Cycle combinations
Best Steroids to Stack With Boldenone
Boldenone is normally stacked rather than used by itself. The best combination depends on whether the goal is bulking or cutting.
| Goal | Common Boldenone Stack |
|---|---|
| Bulking | Testosterone + Boldenone |
| Faster Bulking | Testosterone + Boldenone + Dianabol |
| Heavy Bulking | Testosterone + Boldenone + Anadrol |
| Injectable Bulking Stack | Sustanon + Boldenone |
| Cutting | Boldenone + Trenbolone |
| Dry Cutting Stack | Boldenone + Winstrol |
For most users, Testosterone + Boldenone is the basic starting point. Dianabol or Anadrol can be added when faster size and strength are the priority, while Trenbolone or Winstrol are more suited to cutting-focused cycles.
Bulking
Boldenone for Size & Strength
For bulking, Boldenone is usually paired with testosterone. Because Boldenone builds gradually, users often add an oral steroid such as Dianabol or Anadrol at the beginning of the cycle when they want faster early strength and size.
This gives the cycle a faster start while Boldenone continues working throughout the longer part of the cycle.
Cutting
Boldenone for a Cutting Cycle
Boldenone can also be used during a cutting phase when the goal is to maintain muscle and strength while getting leaner.
Common combinations include Trenbolone or Winstrol, particularly for experienced users who want a harder, leaner look while dieting.
Bottle planning
How Long Does One 10ml Bottle Last?
Each bottle contains 3,000mg total Boldenone Undecylenate.
| Weekly Dose | Approximate Bottle Duration |
|---|---|
| 300mg/week | 10 weeks |
| 400mg/week | 7.5 weeks |
| 600mg/week | 5 weeks |
| 800mg/week | About 3.75 weeks |
For a full 12–16 week cycle, the number of bottles needed depends on the weekly dose used.
