Hormonal Health
Most hormone testing stops at the wrong number.
Key takeaways
- Total testosterone alone is one of the least informative hormone numbers in isolation.
- Free testosterone, SHBG, estradiol, LH, FSH, DHEA-S, thyroid, and cortisol are read together as a pattern.
- Assay method matters: free testosterone and estradiol need sensitive assays to be trustworthy.
- The goal is restoring your functional pattern, not maximizing a single value.
Hormonal health covers how well your body produces and regulates key hormones like testosterone, estrogen, cortisol, and thyroid hormone, the signals that drive energy, mood, recovery, and vitality.
Free testosterone, SHBG, cortisol, DHEA-S, estradiol, LH, and FSH together tell a far more complete story than total testosterone alone. Baseline's hormonal protocols are built around a comprehensive panel, not a single marker.
Hormonal optimization at Baseline is not about maximizing any one number. It is about restoring the pattern associated with how your body functions best, assessed against your own data and adjusted over time.
Biomarkers tracked here: Free Testosterone, Total Testosterone + SHBG, LH and FSH, Estradiol E2, DHEA-S, PSA Total and Free, IGF-1, Cortisol (AM). Full detail on each in the Biomarker Hub below.
Why one number is not an answer
Most testosterone is bound to SHBG and albumin and is biologically unavailable. Free testosterone, the small unbound fraction, is what tissue actually sees. Two people with identical total testosterone can have very different free levels, and very different symptoms, because their SHBG differs.
This is why a man can be told he is normal at 550 ng/dL total while functionally running low, and why a woman's panel cannot be interpreted at all without cycle phase or menopausal status in the picture.
The panel we actually read
- Free and total testosterone, with free measured by equilibrium dialysis or ultrafiltration.
- SHBG, which explains the gap between total and free and is itself moved by thyroid status and insulin resistance.
- LH and FSH, which separate a primary gonadal cause from a pituitary one and change what a protocol should be.
- Estradiol by sensitive LC-MS/MS, relevant in both sexes.
- DHEA-S, an adrenal marker whose levels fall steadily from early adulthood onward.
- Morning cortisol, drawn 8 to 9am, for stress-axis context.
- Full thyroid: TSH, free T3, free T4. Free T3 is frequently the missing explanation.
- IGF-1 and, in men, baseline PSA before anything testosterone-adjacent begins.
Symptoms are data, but they are not specific
Fatigue, low libido, poor recovery, mood flattening, and stubborn central weight gain map onto low testosterone, low thyroid output, high cortisol, iron deficiency, poor sleep, and insulin resistance more or less equally. Treating the first plausible cause without measuring the rest is how people end up on therapy that does not resolve the complaint.
The sequence is measure, interpret as a pattern, then intervene where the pattern points.
What optimization looks like in practice
Foundations first: sleep duration and consistency, resistance training, adequate protein, zinc and vitamin D sufficiency, alcohol reduction, and addressing insulin resistance, which suppresses SHBG and distorts the entire panel.
Where a hormonal protocol is indicated, an independent licensed provider prescribes and monitors it, and we recommend follow-up labs roughly quarterly rather than as an afterthought.
What this means for you
If you have had a single total testosterone drawn and nothing else, you do not yet have a hormonal picture. A full panel with free testosterone, SHBG, thyroid, and cortisol usually changes the conclusion.
