PlexusDx Review
Genetics-led GLP-1 care with microdosing from $129/month
Microdose $129/month, semaglutide from $149/month, tirzepatide from $249/month — all-inclusive
Overview
PlexusDx approaches GLP-1 therapy from an angle nobody else on this list uses: it sells a Precision Peptide Genetic Test covering 151 genetic insights across 49 peptides, 57 SNPs, 48 genes and 14 health pathways, and builds its programs around what that test suggests about how you metabolise these drugs. Programs are all-inclusive with ongoing provider check-ins — microdose GLP-1 at $129/month, semaglutide from $149/month and tirzepatide from $249/month — in weekly injections or daily oral tablets. Disclosure is unusually strong: PlexusDx names its prescribing physicians, Dr. Ana Lisa Carr, MD (NPI 1689841744) and Dr. Kelly Tenbrink, MD (NPI 1346482684), and lists all six compounding partners — Belmar Pharmacy, Strive Pharmacy, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills Pharmacy. Intake takes about five minutes at no charge, clinicians cover all 50 states, and most orders arrive in five to seven business days. The genetic test is a $298 product discounted to $99 after a first program order, so treat it as an add-on rather than something bundled in.
Pros

Cons

- Genetic guidance for GLP-1 dosing is an emerging area, not settled standard of care
- Cancellation and refund terms are not published
- Shipping takes five to seven business days, slower than same-day competitors
