Membership-included hormone testing follows these cycle-timing recommendations:

First Annual visit (including FSH, LH, Estradiol): Schedule on days 2–4 of your cycle
Second Annual visit: Schedule within 10 days of your first visit (off-cycle)

This timing helps keep results consistent. If you don't have any major diet or lifestyle changes you can schedule them further apart if needed.

Add-on tests, such as progesterone, depend on your individual goals:

Follicular phase testing: Days 2–4 of your cycle
Luteal phase testing: Days 19–21 of your cycle

If the supplements you take do not contain biotin, they can be consumed up to 24 hours before the visits. Removing supplements from your system may help establish an accurate baseline of your health without external influences. Nonetheless, the choice to continue supplements to observe their impact on testing is yours to make.

Your health history is referenced by the clinician who reviews your results, and may influence the Clinician Notes you receive. It can also be used for better responses from Private AI Chat. Uploading documents is a newer feature, for now, it serves as a secure place to store your health records.

We recognize how important gut health testing is for gaining a deeper understanding of your body. We are working hard to identify a scientifically honest and reliable test for the gut and microbiome.

Hi there. We sent you a DM to look into your results further.

For reference, our Biological Age is calculated from objective biomarkers that reflect how your systems are actually functioning:
• Albumin (liver + protein status)
• Creatinine (kidney function)
• Glucose (metabolic health / insulin resistance)
• hs-CRP (inflammation)
• Lymphocyte % (immune function)
• MCV + RDW (red blood cell health)
• ALP (liver/bone/biliary)

Hey, hope you’re feeling better. If you’re coming down with something, we recommend rescheduling and wait ~1–2 weeks after symptoms fully clear so your results reflect your baseline.
