ALPHARETTA, GA — April 6, 2026 — PlexusDx today announced the launch of the Precision Peptide Genetic Test — the first dedicated at-home DNA test designed to map individual genetic predispositions across 14 peptide-related biological pathways. Processed on the Illumina Global Screening Array in CLIA-certified laboratories, the test generates 150 genetic insights covering 49 unique peptides, 57 unique SNPs, and 48 unique genes. No other direct-to-consumer genetic test publishes these numbers.

The Problem This Test Solves

The peptide market has grown rapidly, but the tools available to consumers for making informed, biology-first decisions have not kept pace. People are committing to peptide protocols based on generic recommendations, community averages, and broad population data — with no individual genetic baseline to anchor those decisions. Understanding your own biology before investing in any protocol is not a luxury. It is the responsible starting point.

PlexusDx built the Precision Peptide Genetic Test around a straightforward principle: test before you invest. Getting a genetic baseline before beginning any peptide protocol gives you and your qualified healthcare provider a precise, personalized starting point that no generic protocol can provide. Genetics is a guide, not a guarantee — but a precise guide is worth infinitely more than none at all.

What PlexusDx CEO Jay Hastings Says

"People are spending thousands of dollars on peptide protocols without a single data point about their own biology," said Jay Hastings, CEO of PlexusDx. "Generic protocols are built on averages. The Precision Peptide Genetic Test gives you a precise, personalized genetic map across the 14 biological pathways most relevant to peptide protocols — so you can have a real, informed conversation with your healthcare provider before you invest in anything. That's the decision we built this product around."

What the Test Covers: 14 Pathways, 49 Peptides, 150 Genetic Insights

The Precision Peptide Genetic Test analyzes genetic predispositions across 14 biological pathways, generating 150 genetic insights across 49 unique peptides, 57 unique SNPs, and 48 unique genes — all processed on the Illumina Global Screening Array in CLIA-certified laboratories. Results are delivered through the PlexusDx Results Portal as the Peptide Pathways Report — a pathway-by-pathway breakdown of genetic variation organized for use in a conversation with a qualified healthcare provider.

The 14 pathways covered are: Weight Management (33 insights), Longevity & Aging (17 insights), Muscle Growth (15 insights), Skin Health (14 insights), Energy Metabolism (12 insights), Immunity (11 insights), Tissue Repair (9 insights), Mood (8 insights), Cognition (6 insights), Inflammation (6 insights), Reproductive Health (6 insights), Sexual Health (6 insights), Brain Health (4 insights), and Sleep (3 insights).

Two Ways to Access Peptide Pathway Analysis

PlexusDx is launching two products simultaneously to serve both new and existing customers:

  • Precision Peptide Genetic Test — The at-home cheek swab kit for new customers. One test maps your genetic predispositions across all 14 pathways. Available now at plexusdx.com/products/precision-peptide-genetic-test.
  • Peptide Pathways Report — An add-on for existing PlexusDx customers whose DNA is already on file. No retesting required. The full 14-pathway analysis is added directly to your existing Results Portal.

To support the launch, PlexusDx has published a 150-post Peptide Pathways Education Hub — organized across all 14 biological pathways and written to help customers understand their results and inform conversations with their healthcare providers.

Frequently Asked Questions About the PlexusDx Peptide Launch

What exactly launched today and what does the Precision Peptide Genetic Test cover?

PlexusDx launched the Precision Peptide Genetic Test — an at-home cheek swab DNA test that analyzes genetic predispositions across 14 peptide-related biological pathways, generating 150 genetic insights covering 49 unique peptides, 57 unique SNPs, and 48 unique genes. The test is processed on the Illumina Global Screening Array in CLIA-certified laboratories. PlexusDx publishes its full panel composition — pathway counts, SNP counts, gene counts, and peptide counts — because specificity is what makes genetic data actionable. No other direct-to-consumer genetic test publishes these numbers for a panel dedicated to peptide biology.

Does the Precision Peptide Genetic Test tell me which peptides to use?

No. The Precision Peptide Genetic Test analyzes how your genes influence peptide-related biological pathways. It does not recommend, prescribe, or determine which peptides you should use. The results are designed to inform a conversation with a qualified healthcare provider — not to replace one. PlexusDx does not sell, distribute, or recommend specific peptide compounds. Its role is to provide the most specific, accurate genetic map of your peptide-related biology available so you can make more informed decisions with your provider. Genetics is a guide, not a guarantee.

I'm already a PlexusDx customer — do I need to take a new test?

No. Existing PlexusDx customers whose DNA is already on file can add the Peptide Pathways Report directly to their Results Portal — no retesting, no new kit required. The Peptide Pathways Report delivers the complete 14-pathway, 150-insight analysis on top of any genetic test already completed. This is one of the core advantages of the PlexusDx connected platform: your DNA data works across the full product ecosystem.


Important: The Precision Peptide Genetic Test analyzes how your genes influence peptide-related biological pathways. It does not recommend, prescribe, or determine which peptides you should use. This test is designed for educational and wellness purposes and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. Results should be used alongside — not as a replacement for — guidance from a qualified healthcare provider. Consult a qualified healthcare provider before beginning any peptide protocol.
