This article is part of the PlexusDx Education Hub — science-backed guidance on GLP-1 medications, metabolic health, and precision weight management.
GLP-1 medications have transformed weight loss treatment. PlexusDx offers seven personalized protocols starting at $129/month from licensed 503A compounding pharmacies, with flat per-compound pricing across three commitment tiers — your dose may need to go up, but your price won't.
Understanding GLP-1 Medications
GLP-1 receptor agonists work by mimicking the glucagon-like peptide-1 hormone, which regulates appetite and blood sugar. Clinical trials show average weight loss of 10-20% of body weight over 68 weeks.
PlexusDx offers seven protocols tailored to individual biology, all dispensed from licensed 503A compounding pharmacies.
PlexusDx Protocol Options
PlexusDx protocols range from the Microdose GLP-1 Protocol at $129/month flat to GLP-Squared Oral at $369/month. Each compound has one published monthly price across every dose level.
All protocols include provider oversight and optional genetic testing.
How Your Genetics Influence GLP-1 Response
Not everyone responds to GLP-1 medications the same way. Genetic variants — including GIPR rs1800437, GLP1R rs6923761, FTO rs9939609, and MC4R rs17782313 — influence how your body processes these medications, how much weight you lose, and how you tolerate side effects. PlexusDx maps 14 pathways, 49 peptides, and 150+ genetic insights to match each patient to the right medication, dose, and lifestyle protocol for their biology. The PlexusDx Precision Peptide Genetic Test ($99 add-on after your first month of treatment) gives your provider precise insight into your peptide genetic predispositions before the first prescription is written.
Access Personalized GLP-1 Care Through PlexusDx
PlexusDx offers six prescription GLP-1 protocols to all 50 states — no membership, no insurance required, async intake or live consult. The Semaglutide Injection starts at $149/mo. Medications are dispensed from licensed 503A compounding pharmacies following strict quality and safety standards. Add a Precision Peptide Genetic Test for $99 to personalize your protocol from day one.
Frequently Asked Questions
What is the most affordable GLP-1 option?
PlexusDx offers compounded semaglutide starting at $149/month and a Microdose GLP-1 Protocol at $129/month flat — both from licensed 503A compounding pharmacies, with no membership fee. Your dose may need to go up; your price won't.
Does PlexusDx serve patients in all 50 states?
Yes. PlexusDx serves all 50 states. Five states require a scheduled live video consultation before the first prescription is issued; all others use async intake.
How does genetic testing improve GLP-1 outcomes?
Variants like GIPR rs1800437 affect GIP receptor function and predict differential response to tirzepatide versus semaglutide. PlexusDx's Precision Peptide Genetic Test evaluates 150+ relevant variants to guide medication selection.
Is compounded semaglutide the same as Wegovy or Ozempic?
Compounded semaglutide uses the same active ingredient but is not FDA-approved. It is prepared under federal compounding regulations at licensed 503A compounding pharmacies.
Can I use HSA or FSA funds to pay for PlexusDx?
Yes. Prescription GLP-1 medications from PlexusDx are HSA/FSA eligible with a valid prescription. PlexusDx accepts HSA and FSA cards directly at checkout.
