Boldenone 300mg/10ml SIS Labs – Boldenone Undecylenate Injection
Boldenone undecylenate (commonly known as Equipoise or EQ) is a long-acting injectable anabolic-androgenic steroid derived from testosterone. SIS Labs Boldenone 300mg/10ml is a high-concentration formulation designed for extended release and steady anabolic activity.
It is formulated as an oil-based intramuscular injection, widely referenced in bodybuilding and performance contexts for its gradual and sustained effects.
What Is Boldenone 300mg/10ml?
Boldenone undecylenate is a modified testosterone derivative that exhibits a relatively low androgenic profile and moderate anabolic activity. The undecylenate ester provides a slow release into the bloodstream over an extended period.
It is commonly associated with:
- Lean muscle gain discussions
- Endurance and performance narratives
- Gradual strength development
- Long-acting anabolic cycle bases
Key Features of SIS Labs Boldenone
- Injectable formulation (300mg/10ml vial)
- Active ingredient: boldenone undecylenate
- Long-ester slow release profile

(Independent testing has reported that some batches may not always match label concentration exactly, with measured underdosing observed in certain samples.)
How Boldenone Works
Boldenone undecylenate works by binding to androgen receptors, increasing nitrogen retention, protein synthesis, and red blood cell production, which can support oxygen delivery to tissues.

Because of its long undecylenate ester, it releases slowly and remains active for weeks.
