Men's Testosterone, Muscle and Metabolism Testing
Tired, softer through the middle, training hard with nothing to show for it. One lab value will not explain that. A full picture will.
One testosterone number is not a workup
Most men who come in have had a single total testosterone drawn, been told it is within range, and left with no explanation for how they feel. Total testosterone says nothing about how much is free and usable, how much is converting to estradiol, whether the signal from the brain is intact, or whether insulin resistance and thyroid function are suppressing the whole system. We test all of it, then build the plan from what the results actually show.
What we measure
- · Total and free testosterone
- · SHBG and estradiol
- · DHEA-S, LH and FSH
- · Full thyroid panel
- · Fasting insulin and hemoglobin A1c
- · Inflammatory markers
- · Vitamin D, zinc and full nutrient status
These are panels, not single values. Most of the labs we run report more than twenty markers each, and several run well over a hundred, so we read patterns across the whole picture rather than one number in isolation.
What we work on
- · Energy and mental sharpness
- · Libido and drive
- · Muscle building and strength
- · Fat loss and body composition
- · Training structure and recovery
- · Sleep quality and stress load
- · Long-term metabolic health
Coaching alongside the labs
Paul Berens works with men on the training and nutrition side of this: strength programming, body composition, protein and meal structure, and the habits that decide whether lab improvements last. Testing without a plan you can hold for a year is just information. Meet him on the provider page or review our full lab testing menu.

Common questions
What are the signs of low testosterone?
Persistent fatigue that sleep does not fix, loss of morning erections, low libido, difficulty adding or holding muscle, weight settling around the midsection, irritability or flatness of mood, poor recovery from training, and brain fog. Most men notice several of these together over a year or two rather than one dramatic change.
What testing do you run for men?
A full hormone panel rather than a single total testosterone value: total and free testosterone, SHBG, estradiol, DHEA-S, LH and FSH, plus thyroid, fasting insulin, hemoglobin A1c, inflammatory markers, and a full nutrient picture. Testosterone almost never drops in isolation, and treating the number without the context rarely holds.
Can testosterone be raised naturally?
Frequently, yes. Insulin resistance, poor sleep, chronic stress load, low vitamin D and zinc, excess body fat, alcohol, and toxic burden all suppress production. When testing identifies which of those apply to you, correcting them can move numbers meaningfully. Testing tells us whether your case is a production problem, a conversion problem, or a lifestyle-driven suppression.
Do you help with muscle building and fat loss?
Yes. Paul Berens works directly with men on strength, body composition, training structure, and nutrition alongside the lab work. The plan pairs hormone and metabolic testing with a training and nutrition strategy you can actually keep, rather than a generic cut-and-bulk template.
Why does estrogen matter for men?
Testosterone converts to estradiol through the aromatase enzyme, and that conversion runs higher with more body fat, higher insulin, and higher alcohol intake. A man can have adequate total testosterone and still feel terrible because too much of it is converting. That is why we measure estradiol and SHBG rather than testosterone alone.
