Boldenone Undecylenate 300 mg
Description
What is Boldenone Undecylenate 300 (Astera Labs)?
Astera Labs boldenone undecylenate at 300mg/ml, in a 10ml vial. Equipoise at the highest concentration we stock, for the long cycles it needs.
Also sold as Equipoise, EQ or boldenone undecylenate.
Boldenone is a testosterone derivative with a double bond that makes it far milder. It aromatises at roughly half testosterone’s rate, so estrogen is manageable rather than absent, and it is best known for two side effects that people actively want: a sharp increase in appetite, and a rise in red blood cell count that shows up as better endurance.
Boldenone Undecylenate 300 benefits
- Steady, lean gains rather than the rapid weight a stronger compound puts on
- A noticeable increase in appetite, which is the point during a bulk
- Higher red blood cell count, which most people feel as improved endurance
- Mild enough on side effects to run for the long cycles it needs
- 300mg/ml, so a 600mg week is 2ml rather than 2.4ml at the standard 250
Boldenone Undecylenate 300 dosage
- Beginner
- 400mg per week, which is 1.3ml
- Intermediate
- 400 to 600mg per week
- Advanced
- 600 to 800mg per week
- Run alongside
- Testosterone as the base
- Frequency
- Once or twice weekly
- Half-life
- About 14 days
- Cycle length
- 16 to 20 weeks
At 300mg/ml a 600mg week is exactly 2ml, usually split into two injections.
Short cycles waste this compound entirely. The ester is slow and boldenone is mild, so a twelve-week run is mostly spent waiting for it to start.

Who is Boldenone Undecylenate 300 for?
People running long bulking cycles who want steady gains rather than rapid ones. At sixteen to twenty weeks, the volume saved by the higher concentration adds up.
EQUIMED 250 is the same compound at 250mg/ml in sealed ampoules if you prefer that format.
How to use Boldenone Undecylenate 300
Intramuscular injection, once or twice weekly. Wipe the stopper before every draw and rotate sites. The injection technique guide covers the technique.
Frequently asked questions
How long does boldenone take to work?
Longer than almost anything else. The undecylenate ester is slow and boldenone itself is mild, so most people see nothing meaningful before week six and judge it properly around week ten.
That is why boldenone cycles run sixteen to twenty weeks. Running it for twelve is running it for the part where it has not started yet.
Does boldenone really increase appetite?
For most people, markedly. It is one of the few side effects people run a compound for rather than despite, and it is the reason boldenone turns up in bulking cycles for anyone who struggles to eat enough.
It is not universal. A minority report no change at all, and a few find it goes the other way.
Why does it raise red blood cell count?
Boldenone stimulates erythropoiesis more strongly than most anabolics. More red blood cells means more oxygen carried, which is why endurance often improves noticeably.
The flip side is thicker blood. Haematocrit and haemoglobin are the markers to watch, and this is the compound where ignoring them has consequences.
How long does boldenone stay detectable?
Exceptionally long. The undecylenate ester and boldenone’s own metabolites have been detected many months after the last injection, in some cases beyond a year.
If you are tested at any level, boldenone is one of the compounds to think hardest about.
Which boldenone ester should I choose?
Undecylenate unless you have a specific reason not to. It is the standard, it needs the fewest injections, and it matches the long cycles boldenone requires anyway.
Acetate and cypionate exist for people who want a faster clearing option, but boldenone is a slow compound regardless of what ester carries it, so the benefit is smaller than it looks.
