After you complete your online health evaluation, a US-based physician will review your information and recommend a treatment plan. Once you approve your plan, we will ship your medication.

At Healthspan, we are committed to ensuring the effectiveness of the medications we prescribe. This commitment extends to addressing the challenges of bioavailability, which can notably impact the usage and efficiency of certain drugs, including rapamycin. To tackle this, we employ a robust testing program to select the formulations and brands of rapamycin that offer the best absorption levels.

Bioavailability is a key pharmacokinetic parameter that quantifies the percentage of the administered drug dose that successfully reaches systemic circulation and becomes available to exert its therapeutic effect. It’s a measure of the rate and extent of a drug’s absorption.

In assessing the bioavailability of our medications, we measure two critical pharmacokinetic parameters: Cmax and Tmax.

Cmax, or ‘maximum concentration,’ signifies the highest concentration a drug achieves in the body following administration and prior to the introduction of a second dose.

Tmax, or ‘time to maximum concentration,’ denotes the duration it takes for a drug to reach its Cmax post-administration, providing a measure of the drug’s absorption rate.

We believe in personalized care and thus, offer our patients the option to test their individual rapamycin levels. This enables us to understand each patient’s unique absorption profile of the medication, taking into account the variability of their biology. This approach ensures that our patients receive the most effective therapeutic regimen tailored to their individual needs.

Your health protocol includes unlimited access to physicians, pharmacies, and labs as needed, as well as your prescription(s).

Because the use of rapamycin to treat cellular senescence is an off-label use of the medication, we are unable to bill any insurance plan. However, you may want to contact your insurance provider directly to see if you are eligible to file a claim.
