What it is

How to use

• Follow the directions of a prescribing clinician or the product label. Do not exceed the dose recommended by a healthcare professional.
• Typical doses reported in literature vary; individuals should discuss appropriate dosing and monitoring with a clinician before starting.
• Take tablets with food if you experience stomach discomfort. Maintain regular medical follow-up while using androgenic products.

Why it works

• Mesterolone (active ingredient) — a non‑aromatising androgen that is reported to bind SHBG, which can affect the proportion of free circulating androgens.
• Oral dosing — daily oral administration offers a steady, short‑acting presence in the body when used as directed.
• Pharmacological profile — because it does not convert to oestrogens (non‑aromatising), its effects differ from aromatising agents; discuss implications with a clinician.

What to expect

• Individual responses vary. Any perceived changes in physical condition or symptoms can take several weeks and depend on many factors including dose, nutrition, training and baseline health.
• Monitor for side effects and report concerns to a healthcare professional promptly. Regular blood tests and clinical review are advisable when using androgenic agents.

Good to know

• Not for use by anyone under 18. Do not use if pregnant or breastfeeding. Discuss safety if you have known cardiovascular, liver, prostate or endocrine conditions.
• Stop use and seek medical advice if you experience persistent or worrying side effects, such as significant changes in mood, jaundice, or unexpected physical symptoms.
• Avoid self‑medicating or combining with other prescription medicines without professional guidance.
