Is Tirzepatide a Peptide or Is Your Testosterone the Real Issue?
You are exhausted, gaining weight, and your labs say you are fine
You wake up tired even after a full night of sleep.
Your workouts feel harder than they should.
The scale keeps going up even though you barely eat.
You finally check your testosterone.
Your doctor glances at one number and says, “Looks normal.”
Patients say this all the time.
“I don’t feel normal.”
“I’m doing everything and nothing works.”
“I feel like my body is fighting me.”
If that sounds familiar, the problem may not be your effort.
It may be how your labs are being interpreted.
Total Testosterone vs Free Testosterone Explained Simply
This is where most people get confused.
Total testosterone
This is the total amount of testosterone in your blood.
Think of it like money in the bank.
It looks good on paper, but it does not tell you how much you can actually spend.
Free testosterone
This is the testosterone your body can actually use.
This is the part that affects energy, mood, muscle, and fat loss.
You can have normal total testosterone and still feel awful if your free testosterone is low.
Why You Can’t Lose Weight When Free Testosterone Is Low
This is a common frustration we hear on calls.
“I eat less than my spouse and still gain weight.”
“I work out but I look softer than before.”
“I feel tired all the time and unmotivated.”
When free testosterone is low, your body:
- Burns fewer calories
- Builds less muscle
- Stores more fat
- Feels more inflamed
Weight loss feels impossible because your metabolism is slowed down.
Why Conventional Medicine Misses This
In most insurance based care, only total testosterone is checked.
If that number falls inside a wide lab range, the conversation stops.
No one explains:
- How much testosterone is actually usable
- How stress affects hormone binding
- Why symptoms matter more than one number
You leave feeling dismissed and frustrated.
How Functional Medicine Looks at Testosterone Differently
Functional medicine looks at patterns, not just one lab value.
We use advanced testing to look at:
- Total testosterone
- Free testosterone
- Binding proteins
- Cortisol and stress levels
- Inflammation markers
We connect how these labs relate to your symptoms, your weight, and how your body feels day to day.
That is where real answers start.
Is Tirzepatide a Peptide and Why People Ask About It
Yes. Tirzepatide is a peptide.
Peptides are small messengers that tell your body what to do.
Semaglutide and tirzepatide help reduce appetite and control blood sugar.
Many people ask about these because they feel stuck.
Patients tell us:
“I don’t want a quick fix.”
“I’m scared of gaining the weight back.”
“I want to fix the root cause.”
Peptides can help some people short term.
They do not fix low free testosterone.
Supporting the Body, Not Just the Scale
In functional medicine, we also look at foundational support.
Things like sleep, stress, nutrition, and targeted support including peptides when appropriate.
Some patients benefit from tools like hydrolyzed bovine collagen peptides to support joints, gut health, and recovery so their body can respond better to exercise and healing.
Weight loss works best when the body feels supported, not forced.
Why Your Symptoms Matter More Than a Single Lab
If you feel tired every day, that matters.
If weight keeps climbing despite effort, that matters.
If you do not feel like yourself anymore, that matters.
You are not broken.
You are not lazy.
Your labs just may not be telling the full story.
