How to Get TRT in Australia in 2026 — A Step-by-Step Guide

Is TRT Legal in Australia?

Yes. Testosterone replacement therapy is a legal, TGA-approved medical treatment. Testosterone preparations are classified as Schedule 4 (prescription-only) substances under the Therapeutic Goods Administration. This means:

• You must have a valid prescription from a registered Australian doctor (AHPRA)
• Testosterone cannot be legally possessed or supplied without a prescription
• Importing testosterone without authorisation is a criminal offence
• All prescriptions must be based on a confirmed clinical diagnosis, supported by pathology

Step 1: Recognise the Symptoms

The Endocrine Society's 2018 Clinical Practice Guidelines specify that treatment should only be considered in men with both consistent symptoms and confirmed low testosterone on blood testing — not symptoms alone.

Common presentations include persistent fatigue, reduced libido, erectile dysfunction, loss of muscle, increased abdominal fat, mood changes, and brain fog. See our full symptom guide for the complete clinical picture.

Step 2: Get a Morning Blood Test

The cornerstone of testosterone deficiency diagnosis is a morning blood test, collected before 10am. Testosterone follows a diurnal rhythm — levels peak between 7–10am and can fall 20–40% by afternoon.

A comprehensive pre-assessment panel includes:

• Total testosterone — primary screening measure
• Free testosterone — critical when total testosterone is borderline
• LH and FSH — identifies primary vs secondary hypogonadism
• SHBG — affects free testosterone calculation
• Oestradiol — elevated levels suppress testosterone
• Prolactin — elevated prolactin from a pituitary adenoma is a reversible cause
• Full blood count, liver function, lipid profile, PSA (men over 40) — safety baseline

The Endocrine Society guidelines require at least two morning samples confirming low testosterone before commencing treatment.

Step 3: Understand the Diagnosis Criteria

Testosterone deficiency in Australian clinical practice is typically defined as total testosterone below the laboratory reference range — approximately below 8–10 nmol/L — in the context of symptoms.

The Pharmaceutical Benefits Scheme subsidises testosterone for men with total testosterone ≤5 nmol/L on two separate morning tests. Men with levels between 5–12 nmol/L may be clinically appropriate for TRT but will not qualify for PBS subsidy.

Step 4: Find the Right Doctor

In Australia, TRT can be prescribed by:

• General practitioners — the most accessible pathway; GPs can diagnose hypogonadism and prescribe without specialist referral for most patients.
• Endocrinologists — appropriate for complex cases or suspected secondary causes.
• Urologists and sexual health physicians — also authorised to diagnose and prescribe.

Telehealth GP services — including TRT GP Australia — can arrange pathology, conduct assessments via video consultation, and prescribe where clinically appropriate, without an in-person visit or specialist referral.

Step 5: Commencing TRT

Prescriptions are sent electronically (eScript) to your preferred pharmacy. For PBS-listed formulations (primarily Reandron), you pay the standard PBS co-payment.

Your GP schedules a follow-up at 6–8 weeks to review testosterone levels, haematocrit, and symptom response. Once stable, monitoring continues every 3–6 months.
