Dosage & Usage Guidelines

Typical dosage ranges from 300–700 mg per week, split into injections every other day. Masteroxyl 100 is often stacked with Testoxyl Propionate or Trenboxyl Acetate for advanced cutting stacks. For best results, cycle duration is generally 6–8 weeks.

Stacking Advice

Many athletes combine Masteroxyl with compounds that aromatize to offset estrogenic effects. However, Masteroxyl itself has no conversion to estrogen, similar in behavior to Proviroxyl. This makes it ideal for hardening without added bloat.

Post-Cycle Therapy (PCT)

As with all suppressive AAS, include a proper PCT using Clomixyl or Nolvaxyl to restore natural testosterone function and maintain gains.
