- SelfDecode is a broad health genomics platform with a large library of reports. Its peptide report is one of them, not a standalone product.
- PeptidesDNA is a single report: it reads a 144-marker panel against the published research on 31 peptides, with every association labelled by the strength of the evidence behind it.
- PeptidesDNA analyses DNA data you already have for $99, one time. SelfDecode is sold by subscription or with its own kit; check its current pricing.
- Neither report is a guide to using any peptide. For most peptides, no study has tested whether any genotype changes response.
SelfDecode is one of the established names in consumer health genomics, with a large library of reports covering topics from sleep to cardiovascular risk. Its "Response to Peptides" report is one of those reports. If your interest is specifically what your genetics and the peptide research say together, here is how it compares with a dedicated peptide report.
Disclosure: This comparison is published by PeptidesDNA. We have tried to be accurate and fair, and we encourage you to check SelfDecode's current features and pricing on its own website, since both change.
What SelfDecode offers
SelfDecode is a broad health genomics platform. You either upload existing DNA data (23andMe, AncestryDNA and others) or order its own test kit, then access its library of health reports. The peptide report sits inside that library rather than being sold on its own.
Its peptide report covers a few dozen peptides and gives each a response rating based on your DNA. Like ours, it does not give instructions for using any compound.
What PeptidesDNA offers
PeptidesDNA is a single report built for one question. You upload DNA data you already have; we do not sell a kit. We read it against the published peptide research and show what that research does and does not show: a 144-marker panel, 31 peptides covered, every association labelled by the strength of the evidence, including where no study has tested a genotype at all. It is a one-time purchase, available in the US.
How do the two compare?
| Feature | SelfDecode | PeptidesDNA |
|---|---|---|
| Scope | Large library of health reports, peptides among them | Peptides only |
| How it is sold | Subscription or with its own kit (check current pricing) | $99 one-time for DNA data you already have |
| Upload existing DNA | Yes | Yes: 23andMe, AncestryDNA, MyHeritage and others |
| Peptides covered | A few dozen | 31 in the report; 46 in the public library |
| Evidence labelling | Response ratings per peptide | Every association labelled by evidence strength |
| Usage instructions | No | No |
Neither report is a guide to using any peptide, and no genetic report can predict how anyone responds to one. For most peptides, no study has tested whether any genotype changes response. A genetic report can show which variants you carry, what the human research has linked them to, and how strong that research is.
Who might choose SelfDecode?
- You want a broad health genomics platform covering many topics, with peptides as one of them
- You already subscribe and want to see its peptide report first
- You want a platform that also sells its own DNA kit
Who might choose PeptidesDNA?
- You already have DNA data and want it read against the peptide research for $99, one time
- You want each association labelled by the strength of the evidence behind it
- You want to see plainly where no study has tested a genotype
A broad platform against a single report.
SelfDecode is a broad health genomics platform, and if you want many reports in one place it is worth evaluating. PeptidesDNA does one thing: it reads the DNA file you already have against the published peptide research and says what that research does and does not show. Neither is a guide to using any peptide.
Frequently asked questions
Is SelfDecode's peptide report worth it?
It depends what you want. SelfDecode is a broad platform with many health reports, peptides among them. PeptidesDNA is a single report on 31 peptides for $99, one time, with every association labelled by evidence strength. Check SelfDecode's current pricing on its website.
Can I use my 23andMe data with both services?
Yes. Both accept raw genetic data uploads from 23andMe, AncestryDNA and other major providers.
Is either report a guide to using peptides?
No. For most peptides, no study has tested whether any genotype changes response, and neither report replaces a clinician. A genetic report can show which variants you carry, what human research has linked them to, and how strong that evidence is.
