Precision Peptide Genetic Test
Understand your peptide-related biology before you invest. 14 pathways, 49 peptides, 150+ genetic insights from one cheek swab.
Genetic Tests are a one-time purchase
The Precision Peptide Genetic Test turns one cheek swab into 150+ genetic insights across 14 peptide-related pathways, spanning 49 peptides analyzed at the DNA level, covering weight, longevity, muscle, skin, energy, immunity, tissue repair, mood, cognition, brain health, inflammation, reproductive health, sexual health, and sleep.
What your DNA reveals in this test
Weight & metabolic health
How your genes relate to weight management and energy metabolism pathways.
Muscle, growth & tissue repair
How your genes relate to muscle growth and tissue repair pathways.
Longevity, skin & aging
How your genes relate to longevity, aging, and skin health pathways.
Brain, mood, cognition & sleep
How your genes relate to brain health, cognition, mood, and sleep pathways.
Immune, inflammatory & hormonal health
How your genes relate to immunity, inflammation, reproductive, and sexual health pathways.
What this test covers
This test analyzes 151 genetic insights across 14 peptide-related biological pathways, spanning 49 peptides analyzed at the DNA level, grouped into five plain-language areas. Each shows how your genes relate to a pathway, not which peptides to use. Genetics is a guide, not a guarantee.

This test tells you about your biology. It does not tell you which peptides to use, and PlexusDx does not sell or supply peptides. Test before you invest, and consult a qualified healthcare provider before beginning any peptide protocol. For wellness and education, not diagnosis.
