• Form: oil-based solution in a sealed vial (500 mg per ml)

What it is

How to use

• Follow the directions provided by your prescribing clinician and the product leaflet.
• Administration should be performed by a trained healthcare professional or under their instruction. Do not self‑administer unless instructed and trained to do so.
• Keep all dosing, injection sites and any follow‑up monitoring as directed by your healthcare team.

Why it works

• Multiple esters: combining esters with different release profiles produces a more gradual change in circulating testosterone compared with a single short‑acting ester.
• Predictable pharmacokinetics: each ester alters how the active hormone is released and cleared, affecting timing of action.
• Single vial concentration: a 500 mg/ml strength provides a known quantity of active ingredients per millilitre for accurate dispensing under supervision.

What to expect

• Onset, duration and effects vary between individuals and depend on clinical indications, dosing and monitoring. Any questions about expected outcomes should be discussed with your prescriber.
• Regular follow‑up and laboratory monitoring are typically used to assess response and safety when testosterone preparations are prescribed.

Good to know

• Do not use if you are pregnant or breastfeeding, under 18, or without medical supervision.
• Stop use and seek medical advice if you experience severe or unexpected reactions.
• Testosterone products can alter laboratory hormone results and may be detectable in sports or workplace drug testing; check relevant regulations before use.
