THE Panel

Why You Feel Off -- Down to the Marker.

  • Full hormone health, sleep & stress, muscle growth & recovery
  • Cardiovascular, inflammation, metabolism, immunity, longevity & nutrients
  • MD review + 1:1 consult to explain what's actually wrong

Mitochondrial Function & Efficiency

Energy, Aging, physique all start in your cells, measure it.

  • First & only mitochondrial function & efficiency at-home test
  • Diagnoses what bloodwork can't: oxidative stress, NAD+ decline, cell-level burnout
  • Retest in 90 days -- prove your protocol, peptides, or NMN are actually working

Real feedback from real men.

★★★★★

“I had tried supplements and workout programs. TRT finally helped me regain control over my energy. Within the first month I felt stronger, more motivated.”

Free T: 8.2 -> 22.4 pg/mL

John M., 38 . Tampa, FL

★★★★★

“Before peptide therapy I was constantly tired. OTMH dialed in the right protocol. Better sleep, better recovery, better everything.”

Vitamin D: 28 -> 68 ng/mL

Kyle R., 32 . Austin, TX

★★★★★

“Didn't realize how much low T was affecting my daily life. Within weeks, drive, mood, and performance improved.”

Total T: 280 -> 920 ng/dL

The Answers Your Doctor's Panel Can't Give You

One draw. Full picture.
Finally, why you feel off.

Energy, sleep, libido, mood, weight, recovery, heart risk, hormones, thyroid, inflammation -- measured to the marker, reviewed by a board-certified MD, and explained on a 1:1 consult.

Is your protocol working?
Measure it. Don't hope.

Peptides, NAD+, rapamycin, TRT, fasting, cold plunge -- every protocol promises cellular optimization. mescreen™ is the only at-home test that directly reads mitochondrial ATP output, oxidative stress, and mitochondrial network so you can prove your stack is delivering -- or pivot before you waste another quarter.
