Frequently asked questions

What is the GLP-1 & Peptide Pathways Genetic Test?

It is an at-home cheek-swab DNA test that analyzes how your genes influence 14 peptide-related pathways, returning 151 genetic insights across 49 genes and 58 SNPs. Weight Management is the largest pathway and covers GLP-1 and incretin-related biology. Genetics is a guide, not a guarantee.

Does this test tell me which peptides to take?

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, and it does not predict how you will respond to any medication. Consult a qualified healthcare provider before beginning any peptide protocol.

How does the test work and how long does it take?

You collect a quick cheek swab at home, mail it back in the prepaid envelope, and results post to your PlexusDx Results Portal in 2 to 4 weeks. No doctor visit is required. If the test is for a minor, an adult completes registration.

Is this a diagnostic test?

No. The test is for education and wellness, not diagnosis or treatment. It shows long-term genetic tendencies across peptide-related pathways, not a medical condition. Genetics is a guide, not a guarantee. Always consult a qualified healthcare provider about your health.

What genes and pathways does this test analyze?

49 genes and 58 SNPs across 14 peptide pathways.

Weight Management, 34 insights. The largest pathway. Genes: ADIPOQ, CD36, FTO, GIPR, IGF1, LEPR, MC4R, PPARG, TCF7L2.

Longevity and Aging, 17. Muscle Growth, 15. Skin Health, 14. Featured genes include FOXO3, MSTN, and COL1A1.

Ten more pathways: energy, immunity, tissue repair, mood, cognition, brain health, inflammation, reproductive health, sexual health, and sleep.

Does this test cover GLP-1 pathways?

Yes. Weight Management is the largest of the 14 pathways at 34 genetic insights, and it covers GLP-1 and incretin biology.

Eight compounds analyzed at the DNA level, including Semaglutide, Tirzepatide, and Retatrutide.

Key genes include FTO, MC4R, GIPR, TCF7L2, and ADIPOQ.

It does not predict your response. The test does not recommend, prescribe, or determine which peptides or medications you should use, and PlexusDx does not sell or supply peptides. Genetics is a guide, not a guarantee.

Some compounds analyzed are investigational and are not approved by the FDA.
