Dosage & Usage Guidelines

The suggested dosage of Duraxyl 100 is 200–700 mg per week, typically injected every 3–4 days due to its short half-life. Cycle duration ranges from 6 to 8 weeks for optimal results. For experienced users, it is commonly stacked with compounds like Testoxyl Propionate, Masteroxyl 100, or Dianoxyl.

Side Effects

Duraxyl 100 has a low risk of estrogenic or androgenic side effects, but users may still monitor for acne, changes in libido, or mood fluctuations. As a progestin, it may also increase prolactin levels in sensitive individuals.

Post-Cycle Therapy (PCT)

To restore natural testosterone levels, a standard PCT protocol using Clomixyl or Nolvaxyl is recommended starting 2 weeks after the last injection.

Who Should Use Duraxyl 100?

This steroid is suitable for intermediate and advanced users aiming for lean mass with faster clearance. It is especially ideal for shorter cycles or pre-contest prep phases where fast action and less fluid retention are preferred.
