Frequently Asked Questions About Genetic Peptide Testing
What does the GLP-1 & Peptide Pathways Genetic Test actually analyze?
The GLP-1 & Peptide Pathways Genetic Test analyzes your DNA across 14 peptide-related biological pathways, generating 150+ genetic insights covering 49 unique peptides, 58 unique SNPs, and 49 unique genes. The test is processed on the Illumina Global Screening Array in CLIA-certified laboratories. Results are delivered through your PlexusDx Results Portal as the GLP-1 & Peptide Pathways Report — organized by pathway so you can understand which areas of your biology carry the most genetic variation.
Who should take this test?
The GLP-1 & Peptide Pathways Genetic Test is designed for adults who want to understand their genetic predispositions across peptide-related biological pathways before beginning any peptide protocol. It is also valuable for existing PlexusDx customers who want to add peptide pathway analysis to their Results Portal without retesting — available as the GLP-1 & Peptide Pathways Report add-on. This test is intended for educational and wellness purposes. It is not diagnostic and does not replace guidance from a qualified healthcare provider.
Can this test tell me which peptides to use?
No. The GLP-1 & Peptide Pathways 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 prescription programs are a separate service: an independent, U.S.-licensed provider decides whether a medication is right for you, and a state-licensed pharmacy dispenses any prescription. On the testing side, our role is to provide the most specific, accurate genetic map of your peptide-related biology available.
What does "test before you invest" mean?
It means getting your genetic baseline before committing to any peptide protocol. The peptide space involves a significant financial and biological commitment. Understanding your genetic predispositions across 14 relevant pathways — before you begin — gives you and your qualified healthcare provider a precise, personalized starting point. It eliminates a significant category of biological guesswork and gives your provider actionable genetic data to work with. Genetics is a guide, not a guarantee — but a precise guide is worth more than no guide at all.
What are the 14 peptide-related biological pathways in the test?
The GLP-1 & Peptide Pathways Genetic Test analyzes genetic insights across the following 14 pathways: Weight Management (34 insights), Longevity and 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). Total: 150+ genetic insights.
How is this different from other genetic tests?
The GLP-1 & Peptide Pathways Genetic Test is the only direct-to-consumer genetic test that maps all 14 peptide-related biological pathways with 150+ genetic insights across 49 unique peptides — with published counts. Most genetic wellness tests analyze broad health categories without publishing the specific panel composition. PlexusDx publishes exact pathway counts, SNP counts, gene counts, and peptide counts because specificity is what makes genetic data actionable. The test is processed on the Illumina Global Screening Array — the same platform used in clinical and research settings — in CLIA-certified laboratories.
Important: The GLP-1 & Peptide Pathways 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. Results are delivered through the PlexusDx Results Portal. Your DNA does not change — results remain relevant for life.
