Comparison · Lifeforce
Lifeforce is premium clinical-concierge: a performance physician, a health coach and quarterly panel draws, a clinician relationship with optimization protocols that are often hormone-forward. Merlin is a synthesis layer. You can stay with your Lifeforce team and use Merlin to read your panels across years and systems, including the surfaces Lifeforce doesn't focus on: gut, fertility, neuropsychiatric, musculoskeletal.

Concierge bio-optimization with a hormone-replacement lens.
Performance physician, health coach and quarterly panel draws. The model is premium clinical-concierge: a clinician relationship, optimization protocols, often hormone-forward. Strong if you want a clinician overseeing your data with a performance bias and the bandwidth to call you back.
Best for
Anyone with panels they haven't been able to make sense of.
A read, not a panel. Merlin reads whatever you already have - no required panel purchase - the way a functional and integrative medicine clinician would: cross-system reads across blood, imaging, genetics, body composition, gut, musculoskeletal, fertility and neuropsychiatric. Practitioner-friendly. The art-gallery model: the kind that keeps its doors open by keeping them low-cost. Your first month is $35 and reads your results together.
Tell us you're not happy within 30 days of your first charge, and we'll refund you. This covers your first month of Core.
Prices are each platform's own public price, checked in September 2026. Each platform's product evolves rapidly; if anything here is out of date, the underlying structural distinction (cross-source synthesis, surface breadth beyond blood) still holds.
Lifeforce is a clinical service; Merlin is a synthesis layer. You can stay with your Lifeforce team and use Merlin to read your panels across years and systems, including the surfaces Lifeforce doesn't focus on: gut, fertility, neuropsychiatric, musculoskeletal. The two don't have to be either-or.
None of these platforms are either-or with Merlin: the synthesis layer reads whatever panels you already have, no matter who ran them.
A real Cardiovascular surface from a real anonymized panel: a score, a narrative in plain language, 19 biomarkers read in context, a plan, the follow-up testing worth running, and the questions to ask your physician. Every system you have data for gets this depth.
Bring what you have, wherever it came from - PDFs, portal downloads, a photo of a printout. Your first month reads your results together, across every system, then shows you what they mean and what's worth finding out next. If there's a lot, Merlin tells you what order to bring it in.
If you don't feel the value of Merlin after paying for your first month, tell us and we'll refund you in full. Monthly Core, once per person, by email within 30 days. The terms
