Biomarkers measured on this test

TSH (Thyroid Stimulating Hormone)

Your thyroid's control signal, and closely tied to your testosterone. High TSH, a sign of an underactive thyroid, is linked to lower testosterone, low libido, erectile issues, and reduced sperm quality. Fixing your thyroid can help restore all of them.

Free T4 (Thyroxine)

Your main thyroid hormone, which affects how much testosterone your body can actually use. Too much T4 raises SHBG, a protein that binds testosterone and leaves less free T available. That can mean low sex drive, fatigue, and even breast tissue growth.

Free T3 (Triiodothyronine)

The active hormone that drives your strength, muscle recovery, and fat burning. Aggressive cutting and long periods of low calories can drop your T3, which can stall fat loss and leave you flat in the gym even when you're doing everything right.

TPO-Ab (Thyroid Peroxidase Antibodies)

A sign your immune system is targeting your thyroid. Autoimmune thyroid disease is less common in men, so it's rarely tested for and often missed. Raised antibodies can flag Hashimoto's years before symptoms, giving you time to get ahead of it.

How do I know if this test is for me?

Thyroid problems are less common in men, which is exactly why they're so often missed. If you feel off and nobody has checked your thyroid, this test gives you answers from home.

Linked to Low Testosterone

Low energy, low libido, erectile issues, or losing muscle. These symptoms often get blamed on testosterone, but an underactive thyroid can cause them too and can even lower your testosterone.

Weight & Energy Changes

You're gaining non-muscle weight despite eating well and training, or you're dragging through the day. Your thyroid sets your metabolic rate, so if it slows down, so do you.

Wired, Anxious or Racing

You feel restless, anxious, sweat more than usual, or notice your heart pounding. An overactive thyroid speeds everything up and is easy to mistake for stress or too much caffeine.

Proactive / Family History

A parent or sibling has a thyroid condition, or you just want a full baseline. TPO antibodies can flag risk early, and knowing your numbers makes it easier to track changes over time.
