When it comes to bodybuilding performance, Masteron (Drostanolone) and Equipoise (Boldenone Undecylenate) are two compounds often compared. The short answer is:
👉 Choose Masteron if your goal is cutting, muscle hardness, and competition aesthetics.
👉 Choose Equipoise if you want lean mass, endurance, and appetite support for bulking.
Both can be effective, but their purposes are very different, and stacking them strategically can provide the best of both worlds.
🧪 Chemical Breakdown
Steroid | 💊 Compound | ⏳ Half-Life | 💪 Main Purpose | 🌊 Water Retention |
---|---|---|---|---|
Masteron | Drostanolone (Propionate/Enanthate) | 2–3 days (Prop), 7–10 days (Enanthate) | Cutting, dryness, anti-estrogen | ❌ Very low |
Equipoise | Boldenone Undecylenate | ~14 days | Lean bulking, vascularity, RBC boost | ✅ Mild |
📌 Quick Note: Masteron works quickly but clears fast, making it ideal for contest prep. Equipoise, with its long ester, shines in extended bulking cycles.
