Bioavailable Testosterone

• Bioavailable Testosterone — the testosterone your body can actually use. This is your main number.
• Total Testosterone — everything in your blood, usable or not. What a standard test shows.
• Free Testosterone — the small fraction floating completely unbound.
• SHBG — the protein that locks testosterone away. High SHBG means less for you.
• Albumin — the carrier that holds testosterone loosely and releases it easily.

• Your drive is gone — low libido or erection problems
• You’re tired all day and your head feels foggy
• You’re losing muscle, gaining fat, recovery has stalled
• Your testosterone came back “normal” but you still feel low
• You’re being checked for low testosterone or fertility
• You’re on TRT and need to check your dose

• A real answer — why you feel flat, even if your last test said normal
• The number that matters — bioavailable testosterone, not just the total
• Same-day clarity — results in 4–6 hours, not a week of waiting
• A doctor to explain it — included, so you’re not left reading a PDF
• A safe TRT baseline — the right number to start or adjust a dose

1. Book a morning slot — 7 to 10 AM gives the most accurate reading.

2. Don’t eat for 8–12 hours — sleep through most of it, book early.

3. Skip the night before — heavy workouts, alcohol, smoking.

4. Nurse comes to you — a normal blood draw at home or office, 10 minutes.

5. Results in 4–6 hours — in your app, with a doctor call to explain them.
