The short answer

Order from PlexusDx while you still have at least two weeks of Fridays Health medication remaining. PlexusDx ships within 5–7 business days after provider approval; starting your intake 14–21 days before your Fridays supply runs out creates a buffer for consult scheduling, prescription review, and transit time. You may cancel Fridays once your PlexusDx shipment is in hand—or after your provider confirms your first dose if you want absolute certainty. This approach avoids both a gap and paying for two overlapping months of a monthly subscription.

At a glance: transfer steps and timing

Total transition window: 10–14 days from intake start to first dose in most cases. Building in a two-week buffer accounts for weekend gaps, consult scheduling, and occasional shipping delays.

Medication and dose continuity

PlexusDx offers compounded semaglutide injection and compounded tirzepatide injection—the same active pharmaceutical ingredients as Fridays Health's compounded offerings. Concentration and formulation details may differ between compounding pharmacies; your PlexusDx provider will determine the appropriate starting dose based on your current regimen, tolerance, and clinical history. If you are currently stable on a specific dose (for example, tirzepatide 5 mg weekly), communicate that clearly in your intake form and during your consult. The provider may continue the same dose or adjust based on your response and the receiving pharmacy's available concentrations.

Do not assume automatic dose-for-dose continuation. Compounded medications are not FDA-approved, and switching pharmacies may require dose calibration. A licensed clinician determines whether a prescription is appropriate for an individual patient.

Pricing: month-to-month and prepaid tiers compared

Fridays Health tirzepatide pricing (all figures captured September 4, 2026) spans five plan structures. The month-to-month plan bills $389 monthly with no commitment. Prepaid plans offer lower effective monthly rates but require upfront payment: the three-month plan costs $896 every three months ($298.67 per month, prepaid equivalent—our calculation), the six-month plan $1,650 every six months ($275 per month, prepaid equivalent—our calculation), and the twelve-month plan $2,880 upfront ($240 per month, prepaid equivalent—our calculation). Fridays also advertised a "4-for-3" promotional plan at the time of capture: pay $896 for three months and receive a fourth month free, yielding an effective rate of $224 per month over twelve months ($2,688 total—our calculation). This promotion required a three-month commitment and the pattern repeated every four months.

PlexusDx tirzepatide injection pricing is simpler and does not require prepayment. The month-to-month rate is $289 per month. A three-month commitment reduces the rate to $269 per month (billed monthly). A six-month commitment brings the rate to $249 per month (billed monthly). All PlexusDx prices include the provider consult, prescription, medication, and shipping; there is no separate membership fee.

For semaglutide injection, Fridays Health's month-to-month rate was advertised at $249 (captured July 20, 2026); prepaid semaglutide tiers were not documented at the time of research. PlexusDx semaglutide injection is $189 per month (month-to-month), $169 per month (three-month commitment), or $149 per month (six-month commitment).

Tirzepatide: 12-month cost comparison

*Prepaid effective monthly rate—our calculation. All Fridays prepaid figures captured September 4, 2026; promotional 4-for-3 plan was advertised at that time and may not remain available.

PlexusDx delivers lower total cost at the month-to-month, three-month, and six-month tiers without requiring any upfront lump sum. A switcher moving from Fridays' $389 monthly plan to PlexusDx's $289 month-to-month plan saves $1,200 over twelve months. Fridays' twelve-month prepaid plan ($240 per month effective, $2,880 upfront) and the captured 4-for-3 promotional plan ($224 per month effective) yield lower monthly rates than PlexusDx's six-month commitment ($249), but both require committing nearly $3,000 upfront and forgoing month-to-month flexibility.

Semaglutide: 12-month cost comparison

Fridays semaglutide month-to-month rate captured July 20, 2026; prepaid semaglutide plans were not documented at time of research.

PlexusDx's semaglutide month-to-month rate ($189) saves $720 over twelve months compared with Fridays' documented month-to-month rate ($249). The six-month commitment ($149 per month, $1,788 annually) saves $1,200 per year.

Service model differences

Fridays Health bundles unlimited provider visits, one-on-one dietitian support, nutrition coaching, mental-health coaching, and a dedicated care coach into every plan, with no separate membership fee and no advertised lab fees (all features captured July 20, 2026). This comprehensive support structure may benefit individuals who prefer regular coaching touchpoints and integrated behavioral resources.

PlexusDx operates a streamlined clinical model: the all-inclusive monthly price covers the initial provider consultation, prescription, compounded medication, and shipping. A pharmacist (PharmD) check-in is included at no extra charge. The program does not bundle ongoing coaching or mental-health counseling; individuals seeking those services would arrange them separately. PlexusDx offers an optional DNA-based medication-response testing add-on ($99 for program members, $298 standalone, captured July 20, 2026) to inform medication and dose selection, but routine nutrition or behavioral coaching is not part of the core service.

Both programs work with licensed compounding pharmacies. PlexusDx partners exclusively with 503A compounding pharmacies. Fridays Health's pharmacy partnerships were not specified in the sources reviewed.

Overlap strategy: minimizing cost and gap risk

The safest transition approach involves a brief overlap—maintaining your Fridays subscription until you have taken your first PlexusDx dose. In practice, this means starting your PlexusDx intake 14–21 days before your Fridays supply runs out, allowing the new prescription to clear and ship while you still have medication in hand. Once your PlexusDx shipment arrives and you have inspected it (confirm correct medication, dose, intact packaging, and appropriate temperature if applicable), you may cancel Fridays before its next billing date.

If you are on a Fridays prepaid plan (three-month, six-month, or twelve-month), cancellation terms and partial refunds were not documented in the sources reviewed. Contact Fridays Health directly to understand your options; some prepaid telemedicine programs do not prorate or refund unused months. In that scenario, the overlap cost is already sunk, and the decision becomes when to start PlexusDx rather than whether to overlap billing cycles.

For month-to-month Fridays subscribers, canceling immediately after receiving and verifying your PlexusDx shipment avoids paying for two services simultaneously while preserving continuity. If your Fridays billing date falls before your first PlexusDx dose, you may choose to pay one final Fridays month as insurance against any unforeseen delay, then cancel once you have confirmed PlexusDx delivery and tolerance.

What to communicate during your PlexusDx intake

Your PlexusDx provider needs specific information to ensure safe, effective continuation:

• Current medication and dose: State whether you are taking compounded semaglutide or compounded tirzepatide, the dose per injection (for example, "semaglutide 1 mg weekly" or "tirzepatide 7.5 mg weekly"), and your injection schedule.
• Duration on current dose: How many weeks or months you have been at this dose, and whether it has been stable or recently increased.
• Tolerance and side effects: Any nausea, vomiting, gastrointestinal symptoms, or other adverse effects. If you have had no issues, state that clearly.
• Weight and response: Your starting weight when you began GLP-1 therapy, your current weight, and whether you are still losing, maintaining, or experiencing a plateau.
• Most recent labs: If Fridays ordered labs within the past three to six months (hemoglobin A1C, comprehensive metabolic panel, thyroid panel, lipid panel), note the dates and any abnormal findings. The PlexusDx provider may request copies or order new labs if clinically indicated.
• Reason for switching: Whether cost, service preferences, or another factor is driving the change. This context helps the provider understand your priorities and set appropriate expectations.

Honesty and precision in the intake form streamline the consult and reduce the chance of dose miscalibration or unnecessary lab work.

Choose Fridays Health if…

• You value integrated coaching: Fridays' bundled dietitian, mental-health, and care-coach support suits individuals who benefit from regular behavioral guidance and prefer a single-source support team.
• You are willing to prepay for long-term savings: Fridays' twelve-month and 4-for-3 promotional plans (where available) deliver effective monthly rates below PlexusDx's six-month tier, provided you can commit $2,688–$2,880 upfront and accept the liquidity trade-off.
• You are already established and satisfied: If you are stable on a Fridays regimen, tolerating the medication well, and the price difference does not materially affect your budget, continuity with your current provider and care team may outweigh the potential savings from switching.

Choose PlexusDx if…

• You want lower month-to-month cost: PlexusDx's $289 tirzepatide and $189 semaglutide month-to-month rates save $100 and $60 per month, respectively, versus Fridays' documented month-to-month pricing, with no prepayment or long-term commitment required.
• You prefer commitment-based discounts without upfront lump sums: PlexusDx's three-month and six-month commitment plans reduce monthly rates while billing you monthly, avoiding the cash-flow pressure of Fridays' prepaid tiers.
• You do not need bundled coaching: If you manage nutrition, exercise, and behavioral factors independently or through other resources, PlexusDx's streamlined clinical model eliminates services you would not use and reduces cost accordingly.
• You value dosing and medication-format flexibility: PlexusDx offers five formats (semaglutide injection, tirzepatide injection, semaglutide oral, tirzepatide oral, microdose GLP-1) at the same per-dose price structure, allowing format changes without navigating separate product tiers or repricing.
• You want transparent, stable pricing: PlexusDx publishes standing rates with no promotional variability or landing-page price conflicts; the rate you see is the rate you pay, and it does not change by dose level within a given medication.

Timing your last Fridays dose and first PlexusDx dose

GLP-1 receptor agonists have long half-lives—semaglutide approximately one week, tirzepatide approximately five days—which means a missed dose does not immediately eliminate the drug from your system. That pharmacokinetic cushion reduces the clinical risk of a one- or two-day gap, but it does not eliminate the importance of maintaining your weekly schedule for stable appetite suppression and glycemic control.

Ideally, your first PlexusDx dose falls on your usual injection day, using medication that arrived at least one to two days prior. If your Fridays supply will run out on a Wednesday and your normal injection day is Wednesday, start your PlexusDx intake no later than three weeks before that Wednesday. If an unavoidable one-week delay occurs (for example, a consult reschedule or a shipping holiday), you may experience a temporary increase in appetite or a slight uptick in blood glucose, but serious adverse events from a single missed weekly dose are uncommon in otherwise stable individuals. Communicate any such gap to your PlexusDx provider during your consult so the restart dose can be confirmed as appropriate.

Do not double-dose or take doses closer than six days apart to "catch up." If you miss a dose by more than five days, most clinical protocols recommend skipping that dose and resuming on your next scheduled day. Your PlexusDx provider will give you specific guidance if a gap occurs.

Prescription and medical-record transfer

PlexusDx cannot use a prescription written by a Fridays Health provider; each telemedicine platform employs its own licensed clinicians, and prescriptions are not transferable between unrelated entities in this context. Your PlexusDx provider will issue a new prescription based on an independent evaluation. You do not need to request prescription transfer or medical-record transfer from Fridays unless your PlexusDx provider specifically asks for clinical documentation (for example, recent lab results or a history of adverse events). Most GLP-1 telemedicine consults rely on patient-reported history and new provider assessment rather than formal record exchange.

If you want a copy of your Fridays medical records for your own files or to share with the PlexusDx provider, contact Fridays Health's support team and request records under HIPAA access rights. Turnaround time varies by provider; some fulfill requests within days, others may take up to thirty days as allowed by regulation.

Medication storage and inspection

Compounded semaglutide and tirzepatide are typically shipped with ice packs or gel refrigerants and should be refrigerated upon arrival (36–46°F / 2–8°C). Inspect your PlexusDx shipment immediately: confirm the medication name and dose on the vial label match your prescription, check that the vial is intact with no cracks or leaks, verify the solution is clear and free of particles (slight color variation between pharmacies is normal for compounded formulations, but cloudiness or floating material is not), and ensure any included syringes, needles, alcohol wipes, and sharps container are present and undamaged.

If anything is incorrect, damaged, or missing, photograph the issue and contact PlexusDx support before using the medication. Most telemedicine pharmacies replace defective or incorrect shipments at no charge, but you must report problems promptly.

Store your medication in the main body of the refrigerator, not the door (temperature fluctuates more in the door). Do not freeze. Keep the vial in its original packaging to protect it from light. Once you begin using a vial, most compounded GLP-1 formulations remain stable under refrigeration for 28–30 days; your pharmacy will provide specific beyond-use dating on the label.

Insurance, FSA, and HSA considerations

Neither Fridays Health nor PlexusDx accepts insurance for compounded GLP-1 medications as of the evidence capture dates. Both operate as out-of-pocket, direct-to-consumer services. Compounded medications are not assigned NDC codes and are not covered by commercial insurance or Medicare Part D.

You may use Health Savings Account (HSA) or Flexible Spending Account (FSA) funds to pay for PlexusDx medication and services, provided your account administrator accepts telemedicine and prescription expenses (most do). Save your receipt or invoice from PlexusDx for FSA/HSA reimbursement or substantiation. Some HSA/FSA debit cards will process the charge automatically if the merchant category code is recognized; others require manual reimbursement submission.

If you have been using an HSA or FSA card with Fridays, the same card should work with PlexusDx, though you should confirm with your account administrator if you encounter any processing issues.

What happens if you are not approved?

A licensed clinician determines whether a prescription is appropriate for an individual patient. PlexusDx providers evaluate body mass index (BMI), medical history, current medications, contraindications (for example, personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2), and other clinical factors during the consult. If the provider determines GLP-1 therapy is not appropriate or safe for you at this time, they will explain the reasoning and may suggest alternative options or additional evaluation (such as endocrinology referral or further lab work).

If you are denied, PlexusDx does not charge for the consultation in most cases (confirm this policy at intake). You would remain responsible for continuing or canceling your Fridays subscription independently; PlexusDx has no authority or visibility into your Fridays account.

If you are currently stable on a Fridays regimen and denied by PlexusDx for a reason unrelated to your current therapy (for example, a documentation gap or a difference in clinical interpretation), you may appeal the decision by providing additional records or requesting a second-opinion consult. Policies vary by platform; ask the PlexusDx provider or support team about the appeals process during your consult debrief.

Methodology and freshness

Fridays Health pricing and service details were captured from joinfridays.com and associated product pages on July 20, 2026, and September 4, 2026. Tirzepatide plan structures (month-to-month $389, three-month prepaid $896, six-month prepaid $1,650, twelve-month prepaid $2,880, and 4-for-3 promotional plan) were verified at checkout on September 4, 2026. Semaglutide month-to-month pricing ($249) was captured July 20, 2026; prepaid semaglutide plans were not documented. Fridays' advertised lowest rates ($117 semaglutide, $190 tirzepatide) were noted as promotional or prepaid equivalents on September 4, 2026, and are not used in like-for-like comparisons.

PlexusDx pricing was confirmed from published rate cards on July 20, 2026, and cross-checked July 17–23, 2026. All PlexusDx rates are standing, non-promotional prices.

Twelve-month cost totals and effective monthly rates for prepaid plans are our calculations, derived by multiplying per-period cost by the number of periods in twelve months and dividing by twelve where applicable. All prepaid effective monthly figures are labeled as such in tables.

Compounded-medication regulatory statements are drawn from FDA guidance on compounding and state pharmacy law. PlexusDx's Trustpilot rating (4.3 stars, 79% five-star, 83% four-star or higher) was captured September 9, 2026. Fridays Health review data was not available in the sources reviewed.

Shipping, consult scheduling, and dose-continuity guidance reflect standard telemedicine GLP-1 program operations as of mid-2026 and the pharmacokinetic properties of semaglutide and tirzepatide as published in prescribing information and clinical literature. Individual experiences may vary. Confirm all program details, pricing, and policies at the time of enrollment; telemedicine platforms update terms periodically.

Frequently Asked Questions

Can I transfer my unused Fridays medication to PlexusDx or get a refund?

No. Compounded medications are patient-specific prescriptions and cannot be transferred, returned, or refunded once dispensed. You cannot use leftover Fridays medication under a PlexusDx prescription or combine supplies. Use any remaining Fridays medication according to your original prescription and dosing schedule, then begin your PlexusDx supply on your next scheduled dose day. Dispose of expired or unused medication according to local regulations or pharmacy take-back programs.

Will my PlexusDx dose be the same as my current Fridays dose?

Not necessarily. Compounded formulations vary by pharmacy, and your PlexusDx provider determines the appropriate dose based on an independent clinical assessment, your current regimen, tolerance, and the receiving pharmacy's available concentrations. If you are stable on a specific dose, communicate that clearly during your intake and consult. Most providers will continue a well-tolerated dose, but they may adjust if your history, body weight, or clinical factors warrant a change. Do not assume automatic dose-for-dose continuation.

How long does the PlexusDx provider consult take?

Most consults are completed within 24 to 48 hours of intake submission, either asynchronously (the provider reviews your intake and approves or requests additional information via message) or via a scheduled telehealth video call, depending on clinical complexity and your preference. The consult itself typically lasts 10 to 20 minutes if conducted live. Once approved, your prescription is sent to the compounding pharmacy, and medication ships within five to seven business days in most cases.

What if my PlexusDx shipment is delayed and I miss a dose?

GLP-1 medications have long half-lives, so a single missed dose rarely causes serious harm, though you may notice a temporary increase in appetite or blood-sugar fluctuation. If a delay is foreseeable (holiday shipping, weather), contact PlexusDx support as soon as you are aware to explore expedited shipping. If you do miss a dose by more than five days, clinical guidance typically recommends skipping that dose and resuming on your next scheduled injection day rather than doubling up. Communicate any gaps to your PlexusDx provider so they can confirm the restart protocol.

Can I switch back to Fridays if PlexusDx does not work out?

Yes, though you would need to restart Fridays' intake and consult process; your previous Fridays prescription and account do not automatically reactivate. If you canceled Fridays and later decide to return, contact their support team to confirm re-enrollment procedures. Any prepaid funds from a previous Fridays plan are subject to that platform's refund and cancellation terms, which were not documented in the sources reviewed. Switching back involves the same timing and overlap considerations as the original switch—plan for a buffer to avoid gaps.
