Frequently asked questions

It's a simple finger-prick using a spring-loaded lancet — takes about 2 minutes at home. Most people say it's much easier than expected. There are no needles or syringes — just a quick prick and a small blood sample collected in a tube.

First thing in the morning, ideally fasted (water only for 8-12 hours). Testosterone levels peak in the morning and decline through the day, so morning collection gives the most accurate baseline. Avoid testing the day after heavy exercise — it can temporarily elevate liver enzymes and inflammation markers.

Warm your hands under hot water for 2 minutes before testing — this increases blood flow significantly. Hold your hand below your heart and gently massage from your palm towards the fingertip. If you still have trouble, our kit includes spare lancets to try a different finger.

Typically 5 working days from when the lab receives your sample. You'll get an email notification when your results are ready. Results include clear explanations of every marker in plain English — not just a spreadsheet of numbers.

Every result is reviewed by a GMC-registered doctor. If any marker requires medical attention, we'll flag it clearly and recommend you speak to your GP. We provide the clinical context your GP needs. For urgent findings, we'll contact you directly.

NHS reference ranges tell you if you're likely free from disease — they're designed to catch illness. Our optimal ranges, based on sports medicine and longevity research, tell you where you'd function best. You can be 'in range' but far from optimal — which is why you might feel tired, foggy, or sluggish despite your GP saying everything is 'normal'.

Only if your blood test shows something is genuinely low or suboptimal. We never recommend supplements you don't need. If your levels are fine, we'll tell you to save your money. Every recommendation is based on what your blood actually shows — not guesswork.
