More energy. More drive. More you.

Three steps. Free online assessment, then a blood test at any collection centre near you — free if you're 30 or over, $180 under 30. If your levels come back low, you have a phone consult with our doctor who goes through your results and sorts a treatment plan if it's the right call.

The blood test is free from your 30th birthday, and $180 if you're under 30. After that you only pay for the next step when you get there. A consultation with the doctor is $149. If you start treatment, membership is $119 a month for ongoing care, reviews and messaging. Medication is billed separately at pharmacy cost, with no markup from us.

No — Helix doctors can assess and prescribe without a GP referral.

At any partner collection centre near you — we'll send you a referral after your assessment.

Nine markers, not just testosterone. We measure your total testosterone and your free testosterone — the portion actually available to your body, which is often the more useful number. Then the two pituitary hormones, LH and FSH, which tell the doctor whether a low result is coming from the testes or from the signal telling them to work. SHBG is the protein that binds testosterone up; prolactin and oestradiol are the other hormones that shift the picture. Finally haematocrit, how thick your blood is, and PSA, a prostate marker — the two we monitor for safety if you go on treatment.

You'll get clear guidance from our doctor on what your results mean and any next steps.

Most men complete the assessment and book a test within a few days.
