Measure your sirolimus level to dial in your rapamycin protocol 
for safer, smarter, and 
long-term benefit.
Follow The Science

Peak Absorption

Measures maximum blood concentration post-dose to assess therapeutic uptake and dosing strength.

Trough Clearance

Captures the lowest drug level before the next dose to evaluate drug clearance and avoid mTORC2 inhibition.

Mid-Cycle Metabolism

Assesses how quickly sirolimus is cleared between doses to fine-tune frequency and reduce variability.

Individualized Pharmacokinetics

Accounts for unique differences in absorption, metabolism, 
and response to optimize dosing precision.

Sirolimus, Blood Serum

You choose one timing window below

image
(01)
Peak Level (3–4 hrs post-dose)Measures maximum drug absorption. Ideal for determining 
therapeutic exposure.
(02)
Trough Level (just before next dose)Measures minimum drug level. Helps prevent mTORC2 over-inhibition.
(03)
Mid-Cycle Level (72 hrs post-dose)Gauges metabolism and clearance rate between doses.

Great experience with Healthspan

I’ve had a great experience with Healthspan. All of the representatives have been extremely responsive when sending messages on the portal, and I had a great call reviewing my initial labs with Brandon Fell who was extremely knowledgeable and courteous. I’ve started the Rapamycin and Acarbose protocol, and I’m looking forward to seeing what my updated labs will show in a couple months!

Frequently asked questions

VIEW ALL FAQ
VIEW ALL FAQ
What is this panel for?

It measures rapamycin (sirolimus) in your blood to personalize your dose and track therapeutic absorption or clearance.

Why would I need this?

Rapamycin pharmacokinetics vary widely. Testing ensures you're not underdosing (ineffective) or overdosing (potentially harmful).

What’s the difference between peak, trough, and mid-cycle?

Peak = highest concentration (3–4 hrs after dose) Trough = lowest level (just before next dose) Mid-Cycle = level 72 hrs after dose to assess metabolism

How often should I test?

After your first 2–3 doses, and again after changes in dose, brand, or frequency.

Is it available nationwide?

Yes, at 2,000+ labs—except in NY, NJ, and RI due to lab regulations.

How long does it take to get results?

Typically 2–3 weeks after your lab draw.

Do I need to prepare for the test?

No fasting is required. Avoid strenuous exercise 12 hours before your appointment.

Can I use HSA/FSA?

Yes—this test is fully eligible and can be paid for using pre-tax health benefits.
