Primoxyl 100

What is Primoxyl 100 (Methenolone Enanthate)?

Primoxyl 100 by Kalpa Pharmaceuticals delivers 100mg/ml of Methenolone Enanthate, better known as injectable Primobolan. This long-ester anabolic is a favorite for athletes seeking clean, sustainable muscle growth without water retention or harsh androgenic effects. It provides steady results, making it an ideal option for cutting, recomposition, or lean bulking cycles where quality gains are prioritized over sheer size.

Main Effects

• Enhances recovery and nitrogen retention
• Improves muscle density and definition
• Delivers steady, long-lasting anabolic activity
• Mild on the body with minimal estrogenic risk

How Bodybuilders Use It

Primoxyl 100 is typically dosed at 400–800mg weekly, split into 1–2 injections due to its long ester. Cycles run 10–12 weeks, often in combination with other Kalpa compounds. It's commonly used by athletes who want a refined, lean physique without excessive mass gain or bloating.

Recommended Stacks

• Primoxyl 100 + Testoxyl Enanthate 250 for lean size and stability

Side Effects and Control

Primoxyl 100 does not aromatize, so estrogenic effects like water retention or gyno are not a concern. It's mild compared to most injectables, but users should still monitor liver health and overall well-being during long cycles. Cycle support supplements enhance safety and results.
