A clear, honest guide to who this service is for, what the process involves, and what to expect from the medical assessment.
Helix is designed for Australian men who are experiencing symptoms that may be related to low testosterone — and who want a proper medical answer, not guesswork. The service is available to men aged 18 and over, anywhere in Australia.
You don't need a GP referral to start. You don't need a prior diagnosis. You just need to be willing to go through a proper medical process — because that's the only way to know for certain.
Important: This page is a general guide, not a clinical assessment. Whether TRT is appropriate for you is determined entirely by a qualified doctor after reviewing your blood results and medical history. Beginning the assessment does not guarantee treatment.
Men come to Helix for different reasons. Some have a strong suspicion their testosterone is low. Others are simply tired, flat, or not performing the way they used to and want to understand why. Both are valid starting points.
The symptoms most commonly associated with low testosterone include:
These symptoms are not exclusive to low testosterone — they can have other causes. That's exactly why a proper blood test and medical review matter. Assessment identifies whether low testosterone is genuinely contributing, or whether something else is at play.
Based on established clinical guidelines, TRT is generally considered appropriate for men who have:
Helix follows RACGP and Endocrine Society of Australia guidelines. Treatment is only ever offered where it is clinically appropriate and where the doctor is satisfied it is in the patient's best interest.
TRT is not appropriate for everyone. There are situations where a doctor will advise against it or recommend an alternative approach. These include:
TRT suppresses sperm production and can affect fertility. Men planning to father children in the near future should discuss alternatives with their doctor before starting.
Men with a history of prostate cancer or significantly elevated PSA levels are generally not suitable candidates for TRT without specialist input.
Certain cardiovascular conditions may affect whether TRT is appropriate. Your doctor will review your medical history as part of the assessment.
If your blood results show testosterone levels within the normal clinical range, TRT will generally not be prescribed — regardless of symptoms. Other causes will be explored instead.
Untreated sleep apnoea can both mimic and worsen low testosterone symptoms. Your doctor will consider this as part of their assessment.
In younger men, TRT requires particularly careful consideration and specialist input, as testosterone levels may still be developing.
If TRT is not appropriate for you, your doctor will explain why clearly and outline what your actual next steps should be. You'll never be left without a plan.
If you decide to proceed after the assessment, here's what to expect:
Complete the confidential symptom questionnaire online. A Helix doctor reviews your responses and determines whether blood testing is the appropriate next step.
Your doctor sends you a pathology referral. You take it to any Sonic Healthcare or Australian Clinical Labs near you. Bulk billed — $0 cost to you.
A 20-minute telehealth consultation to review your results and symptoms. Your doctor gives you a clear verdict and outlines your options.
If you're clinically eligible and choose to proceed, your doctor prescribes a personalised protocol. Medication is delivered to your door. Ongoing monitoring is included.
A blood test is not optional — it is the medical foundation of this process. Without confirmed bloodwork, no doctor can responsibly prescribe testosterone therapy. The blood test is what separates evidence-based medicine from guesswork.
Helix orders a comprehensive hormone panel that includes total testosterone, free testosterone, LH, FSH, SHBG, oestradiol, PSA, and haematocrit. This gives the doctor a complete picture, not just a single number. See our blood testing guide for full details.
The assessment is free, takes three minutes, and won't commit you to anything. You'll know exactly what your options are before spending a dollar.
