Package report and all individual reports are also available as standalone documents.
Don't start peptides until you know how your body will respond.
A one-time DNA test scores 43 therapeutic peptides — cognition, recovery, GLP-1s, longevity — as Highly Optimal, Optimal, or Less Optimal based on your unique markers.

Peptides are not one-size-fits-all
The same peptide can be Highly Optimal for one person and Less Optimal for another. Your report is built around your genotype — not a generic protocol.
Across the report it scores 43 peptides scored. Your DNA doesn't change. Test it once and you stop guessing.
What you can actually do with this
Walk into your appointment with something specific
Genotype-level detail is a different conversation than “something feels off.” Bring the specific variants your provider can act on.
Know which risks are worth monitoring earlier
A genetic tendency isn't a diagnosis. It's a reason to screen ahead of the standard age, or ask for the marker nobody was going to check.
Recommendations tied to your genotype
Every insight is scored against your own DNA — no more one-size-fits-all protocols.
What this report changes for you
Stop guessing. Every recommendation is tied to your specific genotype — not generic wellness advice.
Personalized, not generic
Every insight is scored against your own DNA — no more one-size-fits-all protocols.
Know what actually works
Skip the trial-and-error. See which supplements, foods and habits your genes respond to.
Catch risks early
Genetic risk flags let you take preventive action years before symptoms appear.
Save time and money
Stop buying supplements that won't help you. Prioritize the ones that will.
Actionable next steps
Every trait comes with a clear, plain-English recommendation you can start today.

Common questions
Do I need a separate DNA test if I already ordered another Marrow report?+
No. One cheek swab powers every DNA report you order — now and in the future. If you already sent a sample, we'll run this report from your existing data.
Is my genetic data safe?+
Yes. Your DNA is encrypted, never sold, and never shared with insurers or employers. You can delete it any time.
How is this different from 23andMe or Ancestry?+
Consumer DNA kits tell you about your heritage. Marrow analyzes the same DNA against peer-reviewed clinical research to give you specific health guidance for your genetics.
Do I need a doctor to order this?+
No prescription needed. This is a direct-to-consumer wellness report — though we recommend discussing significant findings with your physician.
Will results change over time?+
Your DNA is fixed for life, so your genotype won't change. As new research is published, we update your report at no extra cost.
Peptide scoring is mechanism-based. The laboratory notes that these claims have not been verified by scientific research — they are hypotheses derived from each peptide's known pathways, and few genetic variants have been shown to modify therapeutic peptide effectiveness. Treat this report as a starting point for a conversation with your provider, not a clinical recommendation.
One cheek swab. Lifetime of insight.
