Yes — genetic testing can guide hormone replacement, but "guide" means something more precise than "predict" or "prescribe." The Precision Peptide Genetic Test maps six Reproductive Health insights across 14 pathways, 49 peptides, and 150+ genetic insights that give providers and patients a defined biological starting point before any hormone support protocol begins.

In the Precision Peptide Genetic Test, the Reproductive Health pathway delivers 6 insights across the genes governing estrogen Phase 1 metabolism, Phase 2 clearance, methylation supply, and receptor sensitivity. Part of 14 pathways, 49 peptides, and 150+ genetic insights, these 6 variants map women's estrogen biology as a connected system — not a checklist of isolated traits.

HRT works differently for every woman because the biological systems that process estrogen are individually variable — and genetics is the layer that explains those differences most precisely. The Precision Peptide Genetic Test maps six variables across 14 pathways, 49 peptides, and 150+ genetic insights that determine how your body handles any hormone support protocol.

Multiple genes shape estrogen levels in women — from production through metabolism to clearance and receptor response. The Precision Peptide Genetic Test analyzes the key variants across 14 pathways, 49 peptides, and 150+ genetic insights, giving providers the genetic picture that estradiol blood tests alone cannot deliver.

Two women begin the same hormone support protocol on the same day. Weeks later, one feels significantly better — symptoms eased, energy restored. The other notices little change or unwanted effects. The Precision Peptide Genetic Test maps six biological variables across 14 pathways and 150+ genetic insights that explain this gap — not chance, but genetics.

The Precision Peptide Genetic Test analyzes SULT1A1 — the sulfotransferase enzyme that runs a methylation-independent route to estrogen clearance. Part of 14 pathways, 49 peptides, and 150+ genetic insights, your SULT1A1 Arg213His genotype determines how quickly sulfation neutralizes estradiol and its metabolites for excretion — a parallel Phase 2 pathway that COMT genetics alone cannot capture.
