TL;DR
- 1.SelfDecode covers 1,500+ health reports including peptides — it's a broad platform, not a peptide specialist.
- 2.Their peptide report requires a subscription ($418+/yr). Cancel and you lose access.
- 3.PeptidesDNA is $99 one-time for upload, includes CYP metabolism panel and evidence-tiered scoring that SelfDecode doesn't.
- 4.SelfDecode is better if you want broad health genomics. PeptidesDNA is better if your goal is specifically peptide protocol optimization.
SelfDecode is the most established name in consumer genomics health reports, with over 1,500 reports covering everything from sleep to cardiovascular risk. Their "Response to Peptides" report is one of those 1,500+ — and it's only accessible through a subscription that starts at $418/year.
If you're specifically interested in understanding how your genetics affect your peptide response, is SelfDecode the right choice? We compared their offering against dedicated genetic peptide tests to help you decide.
What SelfDecode Offers
SelfDecode is a broad health genomics platform. You either upload existing DNA data (23andMe, AncestryDNA, etc.) or order their proprietary test kit. From there, you get access to their library of health reports — organized by topic.
Their peptide report ("Response to Peptides") is one report within this library. It's not a standalone product — you need an active subscription to access it.
Subscription Tiers
- Essential: ~$29/month (billed annually at $348) — access to basic reports
- Essential+: ~$35/month (~$418/year) — access to all reports including peptides
- Ultimate: ~$70/month (~$840/year) — includes their DNA test kit + all reports
To access the peptide report specifically, you need at least the Essential+ tier at $418/year — and that subscription renews annually.
What You Get in the Peptide Report
SelfDecode's peptide report covers approximately 43 peptides with genetic associations. For each peptide, they provide:
- A general overview of the peptide's mechanism
- Gene variants that may affect response
- A personalized score based on your uploaded DNA data
- General recommendations
The reports use SelfDecode's proprietary polygenic scoring system and are generated automatically from their database.
What's Missing
SelfDecode is a general-purpose platform that happens to include peptides. This creates some specific gaps for peptide-focused users:
No CYP Metabolism Panel
The most clinically relevant genetic factor for peptide users is their CYP enzyme metabolism profile — specifically CYP2D6, CYP3A4, and CYP2C19 status. These determine how you metabolize not just peptides, but the prescription medications you're likely taking alongside them. SelfDecode's peptide report doesn't include a dedicated CYP metabolizer phenotype assessment in the context of peptide protocols.
No Stacking Interaction Analysis
Most serious peptide users don't take one peptide — they stack two or three. SelfDecode reports on each peptide individually but doesn't analyze how your genetics affect multi-peptide protocols (e.g., the Wolverine Stack, or BPC-157 + GHK-Cu combinations).
No Evidence Tiering
Not all genetic associations are equal. A CYP2D6 metabolizer status has decades of clinical pharmacogenomics data behind it (CPIC Level A evidence). A gene-peptide association from a single rat study is interesting but speculative. SelfDecode presents all associations at roughly the same confidence level.
Subscription Lock-In
If you cancel your subscription, you lose access to the peptide report. Your one-time genetic data requires an ongoing payment to view your results — even though your DNA doesn't change.
How does PeptidesDNA compare to SelfDecode for peptides?
| Feature | PeptidesDNA | SelfDecode |
|---|---|---|
| Price | $99 one-time (upload) / $299 (kit) | $418+/year (subscription) |
| Focus | Built entirely for peptide matching | Peptides as 1 of 1,500+ reports |
| SNPs | 120 peptide-relevant SNPs | Broader but less targeted |
| CYP panel | Dedicated CYP metabolizer assessment | Not contextualized for peptides |
| Evidence tiering | Tier 1/2/3 per association | Flat scoring system |
| Stacking analysis | Multi-peptide interaction analysis | Individual peptide reports |
| Data ownership | Permanent PDF report | Requires active subscription |
| Scope | Peptides only | 1,500+ health topics |
When SelfDecode Makes Sense
SelfDecode is the better choice if:
- You want a broad health genomics platform covering sleep, cardiovascular risk, nutrition, and hundreds of other topics — with peptides as a bonus
- You're already a SelfDecode subscriber and want to check their peptide report before buying a dedicated test
- You value their AI-powered health recommendations across all areas of health, not just peptides
When PeptidesDNA Makes Sense
PeptidesDNA is the better choice if:
- Your primary goal is peptide protocol optimization
- You want a CYP metabolism panel interpreted specifically for peptide use
- You use or plan to use peptide stacks and need interaction analysis
- You want evidence-tiered reporting so you know which results are clinically robust vs. exploratory
- You want a one-time payment and permanent access to your results
- You already have DNA data from 23andMe or AncestryDNA and want a $99 analysis
SelfDecode is the Swiss Army knife. PeptidesDNA is the scalpel.
SelfDecode is an excellent broad health genomics platform. If you want 1,500+ health reports, it delivers real value. But for peptide-specific genetic matching — with CYP panels, evidence tiering, and stacking analysis — a dedicated tool gives you deeper results at $99 one-time vs. $418/year recurring. Your DNA doesn't change. Your bill shouldn't have to either.

Frequently asked questions
Is SelfDecode worth it for peptide reports?
It depends on your goals. If you want a broad health genomics platform covering 1,500+ topics with peptides as one feature, SelfDecode delivers value at $418+/year. If your primary interest is peptide protocol optimization, a dedicated test like PeptidesDNA ($99 one-time) provides deeper peptide-specific analysis including CYP metabolism panels and stacking interaction analysis.
Can I use my 23andMe data with both services?
Yes. Both SelfDecode and PeptidesDNA accept raw genetic data uploads from 23andMe, AncestryDNA, MyHeritage, and other major providers. With SelfDecode you'll still need a subscription ($418+/year) to access the peptide report. With PeptidesDNA the upload analysis is a one-time $99 payment.
How many peptides does SelfDecode analyze vs PeptidesDNA?
SelfDecode covers approximately 43 peptides in their Response to Peptides report. PeptidesDNA analyzes 25+ peptides but with deeper analysis per peptide — including CYP metabolism impact, evidence tiering, and stacking interaction data. More peptides isn't always better; depth and clinical relevance of analysis matters more.
Do I lose access to my SelfDecode peptide report if I cancel?
Yes. SelfDecode operates on a subscription model. If you cancel your Essential+ or Ultimate subscription, you lose access to all reports including the peptide report. Your genetic data is retained, so you can resubscribe later to regain access. PeptidesDNA delivers a permanent PDF report with one-time payment.
