Full head-to-head: PlexusDx vs Fridays →
Someone comparing Brello and Fridays is really asking a pricing-and-structure question: two GLP-1 telehealth brands, similar molecules, different terms. This piece lines them up as of April 2026, leans on published rates only where a brand states them, and points you back to each source for anything that can move overnight.

Brello at a glance
Brello (Brello Health) runs a telehealth-plus-compounding model. A licensed provider evaluates the patient, and eligible prescriptions are filled either as branded FDA-approved GLP-1 products or as compounded semaglutide or tirzepatide through a 503A pharmacy. Check Brello's own site for its current menu and terms at the time you read this.
Fridays at a glance
Fridays (Fridays Health) operates the same telehealth-plus-compounding structure, with published rates on its official website. As of Fridays' own pricing page (joinfridays.com/pricing, verified 2026-07-20), it advertised compounded semaglutide at $249/mo and compounded tirzepatide at $359/mo as ongoing month-to-month rates, with $0 membership, free shipping, and coaching and dietitian support included. Prepaid multi-month bundles lower the per-month equivalent; a paid-annually plan worked out to roughly $150/mo for semaglutide and $240/mo for tirzepatide.
Where the money goes
Fridays' rates moved materially within a single day, which is exactly why secondhand figures age badly — verify both brands at their own pricing pages before deciding. For reference, PlexusDx leads with month-to-month pricing of $189/mo for Semaglutide Injection and $289/mo for Tirzepatide Injection, roughly $60 to $70 below Fridays' advertised month-to-month for each compound; Fridays also sells prepaid 3- and 6-month bundles. The right answer depends on whether you prefer flexibility or a prepaid commitment.
The pharmacology both share
Neither brand owns the science. GLP-1 receptor agonists (semaglutide, liraglutide, dulaglutide) and the GIP/GLP-1 dual agonist tirzepatide modulate appetite, satiety, and gastric emptying identically regardless of storefront. The trial record — STEP for semaglutide (NEJM, 2021), SURMOUNT for tirzepatide (NEJM, 2022), and SURMOUNT-OSA (NEJM, 2024) — belongs to the compound, not the platform.
Flexibility versus commitment
The core trade-off between these programs is contractual, not chemical. Month-to-month billing keeps you free to pause or switch, while prepaid multi-month bundles trade that freedom for a lower effective rate. Fridays' own annual figures show how steep that discount can be. Decide which you value more before letting a per-month number settle the question. If you are early in a trial-and-error phase, flexibility usually wins; once you are settled on a compound and dose, a prepaid plan can reward that certainty with real savings.
The genetic context neither includes
Both brands prescribe into a biology they never chart. TCF7L2, tied to glucose homeostasis and GLP-1 secretion, sits alongside GLP1R, FTO, and MC4R as pathway-level markers of your baseline metabolic terrain. They do not predict any compound's effect, but they describe what a clinician is prescribing into. The PlexusDx Precision Peptide Genetic Test reads 14 pathways, 49 peptides, 150+ genetic insights. PlexusDx also offers the compounds themselves through its Weight Management Protocols — Semaglutide Injection, Semaglutide Oral, Tirzepatide Injection, and Tirzepatide Oral — and the genetic test does not predict response to any specific medication.
Independence note: PlexusDx is not affiliated with Brello or Fridays and reviewed both as market education.

Editorial disclaimer: This comparison is educational. PlexusDx has no tie to Brello or Fridays but sells semaglutide and tirzepatide through its own protocols, so treat this as a disclosed, interested viewpoint. The Precision Peptide Genetic Test maps gene-pathway influences and does not predict medication response. Consult a qualified provider before starting any protocol.

Frequently Asked Questions
Is Brello or Fridays cheaper?
It depends on commitment. As of its verified 2026-07-20 pricing page, Fridays listed compounded semaglutide at $249/mo and tirzepatide at $359/mo month-to-month, with prepaid annual plans lowering those to roughly $150 and $240. Brello posts its own rates, so compare both at the source before deciding.
Do month-to-month or prepaid plans cost less?
Generally prepaid multi-month bundles reduce the per-month figure while month-to-month keeps flexibility. Fridays' annual plan illustrates the trade-off clearly. PlexusDx leads with month-to-month pricing of $189 for Semaglutide Injection and $289 for Tirzepatide Injection; weigh flexibility against a longer commitment.
Does the genetic test change which brand I should pick?
No. The Precision Peptide Genetic Test analyzes pathway-level variants in TCF7L2, and related genes describing baseline metabolism. That context applies whichever brand prescribes, and it never predicts how you will respond to a specific compound or which program suits you best.
