Primoxyl 100 is Kalpa Pharmaceuticals' injectable version of Methenolone Enanthate, dosed at 100 mg/mL. Known under the trade name Primobolan, this mild anabolic steroid is favored by athletes during cutting cycles or recomposition phases where lean muscle retention and minimal side effects are the goal.
Primobolan offers slow, steady gains in lean muscle tissue while improving vascularity and hardness. Its non-aromatizing nature means there is no risk of estrogenic side effects like water retention or gynecomastia. Clinical literature supports its mild androgenic profile and tolerability.
Primoxyl 100 is commonly dosed at 400–600 mg per week, split across two injections. A cycle can last 10–12 weeks. It is an excellent choice for users looking to maintain muscle mass during caloric deficits without bloating or fat gain.
For optimal results, stack Primoxyl with Testoxyl Cypionate or Masteroxyl 200 to support anabolic balance. Cutting agents like Oxandroxyl or Clenbutaxyl are also popular companions during fat-loss phases.
While Primoxyl is not highly suppressive, PCT is still recommended after a full cycle. Begin Clomixyl or Nolvaxyl approximately 14 days after your last injection to restore endogenous testosterone levels.
Yes, Primoxyl is considered one of the safest injectable anabolic steroids, making it a good option for beginners focused on cutting or lean bulking.
No, Methenolone Enanthate does not aromatize to estrogen, so it does not cause water retention or gynecomastia. It is often used for dry, lean gains.
