Do you offer Hormone Replacement Therapy (HRT)?
Yes! BLI has been specializing in advanced Bioidentical Hormone Replacement Therapy since our inception in 2006. We believe hormone replacement is critical to healthy aging, and it is even more critical to ensure safe hormone replacement therapy by monitoring hormone metabolism using testing like the DUTCH Test. Hormones are only available to clients under our ongoing care Programs to ensure safe management and ongoing oversight of their hormone replacement therapy and care.
Do you work with peptides?
Yes! BLI was one of the first clinics in the nation to create a formal Medically Managed Peptide Program. We believe that just like hormones, peptides decline with age and need replacing. Peptides offer another critical tool in the overall longevity toolkit. We only source our peptides from FDA-regulated compounding pharmacies, ensuring the highest quality and safest ingredients.
How are your services structured?
Our core foundational health services have two key components: Assessment → Program
Prior to enrolling in a BLI Program, you will need to complete a BLI Assessment. The Assessment is a standalone, one-time cost that includes an Initial Consult, a comprehensive lab panel, and a Lab Review & Protocol Recommendation appointment. Upon completing your Assessment, you have the choice to then continue with a Program (or not).
What is included in a BLI assessment?
An Assessment includes 2 appointments and a curated, comprehensive lab panel. The Assessment process is as follows:
- You will meet with a BLI Provider for an Initial Consult to discuss goals, concerns, and medical history.
- Then, you will be given a Lab Order for a curated Lab Panel designed specifically to provide the baseline information needed to define a safe, medically managed treatment protocol.
- Once your lab results are in, you will meet with your Provider for your Lab Review and Protocol Recommendation visit to define your fully personalized treatment protocol moving forward.
- After this appointment, your Assessment is complete. Our commitment to you is you will know more about your baseline physiological health than ever before. Now you can decide if you want to continue with BLI in an ongoing Program, just keep your Assessment for future reference, or even take your information to another provider. It’s your call.
After the Assessment, the overwhelming majority of Clients typically move into an Optimization Program with BLI. BLI’s ongoing Programs provide continued care and generally run for the calendar year (prorated for mid-year start dates). While in a Program, you will have unlimited provider access, follow-up lab reviews for your specific treatment protocol, and prescription management. Our Programs do not include medications, the cost of follow-up labs, or supplements.
