OUR MISSION & VISION

We give men the full picture on TRT — real research, real benefits, and real risks — so you can make informed decisions and take control of how you age.

We believe real stories spark real change. When men understand their options and take charge of their health, their transformations inspire others to do the same.

TRUSTED REVIEWS

“Before getting my testosterone level checked and starting treatment, I would drag my feet trying to get through my day. Now I pursue life with the same vigor and excitement as I had in my youth. My treatments have shed all the years of wear and tear from life and has reinvigorated me to show the person I always knew was inside, but buried by years of living life to the fullest…Thanks to The Mark.”

“I've been a client for about 6 months. My sleep has really improved, I no longer rely on daily energy drinks, I've been more consistent in the gym, and I'm down 15lbs. Of course results will vary but if you're a couple of decades from 18 and have some low T symptoms, I recommend everyone at least get their testosterone labs to see where they stand. The guys in the clinic are all great people, very personable, knowledgeable and professional... 10/10!”

LOW T LABS FAQ’s

  • An appointment is not required, and walk‑ins are welcome. However, booking ahead lets us prepare for you and usually gets you in and out much faster.

  • Stop taking biotin (Vitamin B7) three days before your testosterone test—it can falsely raise testosterone levels. Check supplements, energy drinks, and protein powders for biotin.

    Avoid natural testosterone boosters (ashwagandha, tribulus, shilajit, maca) for a week to ensure accurate results.

    Fasting is not required for testosterone testing.

  • Testosterone labs typically result in 24hours.

  • Testosterone lab results from the past six months may be valid. Contact us to confirm.

  • Currently with another provider? Contact us to discuss transferring your care.

  • We apologize for the inconvenience, but we are a self-pay clinic only. We accept Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA).
