PlexusDx works with licensed 503A compounding pharmacies. A licensed clinician determines whether a prescription is appropriate for an individual patient.

The short answer

IVIM Health sells compounded semaglutide and tirzepatide in prepaid 4-month or 6-month medication bundles—$600 upfront for six months of semaglutide, for example—with a separate $75/month membership fee (first month free). PlexusDx offers the same compounded injections month-to-month at $189 for semaglutide or $289 for tirzepatide, no membership, no upfront commitment. To switch without missing a dose: complete your PlexusDx intake one week before your final IVIM dose runs out, coordinate your first PlexusDx shipment to arrive as IVIM supply ends, and cancel IVIM membership after your prepaid medication bundle is exhausted. IVIM's prepaid structure means you own the medication already paid for; the timing challenge is ensuring the new provider's prescription and shipment slot into your existing schedule.

IVIM Health vs PlexusDx at a glance

All IVIM Health pricing verified 2026-09-04; PlexusDx pricing verified 2026-09-07.

The full cost picture: effective monthly rates over 12 months

IVIM Health advertises a $100/month semaglutide rate, but that figure represents only the medication portion of a 6-month prepaid bundle ($600 upfront) and excludes the separate $75/month membership fee. Over six months, assuming the first membership month is free, you pay $600 medication + ($75 × 5 months) = $975 total, or $162.50 per month (our calculation). If you renew the 6-month bundle twice over 12 months and the first-month-free membership benefit repeats, the 12-month cost is $1,200 medication + $750 membership = $1,950 total, or $162.50 per month (our calculation). If the first-month-free benefit applies only once, membership costs $825 over 12 months and the medication $1,200, raising the 12-month total to $2,025 and the effective rate to $168.75/month (our calculation).

PlexusDx charges $189/month for compounded semaglutide injection on a month-to-month basis—medication, provider access, and shipping included, no membership. Over 12 months that is $2,268 total, or $189 per month. On a 6-month commitment, PlexusDx semaglutide drops to $149/month, or $1,788 over 12 months (our calculation).

For tirzepatide, IVIM's 6-month prepaid bundle costs $1,100 upfront ($183.33/month medication equivalent) plus the $75/month membership (first month free). Over six months, that is $1,100 + ($75 × 5) = $1,475 total, or $245.83 per month (our calculation). Over 12 months with two renewals and assuming the first-month-free benefit repeats, the total is $2,200 medication + $750 membership = $2,950, or $245.83 per month (our calculation).

PlexusDx tirzepatide costs $289/month month-to-month ($3,468 over 12 months, our calculation) or $249/month on a 6-month commitment ($2,988 over 12 months, our calculation).

The table below normalizes these figures to like-for-like 12-month totals:

All 12-month totals and effective monthly rates are our calculations based on verified pricing as of 2026-09-04 (IVIM) and 2026-09-07 (PlexusDx). IVIM calculations assume the first-month-free membership benefit repeats with each 6-month medication bundle renewal; if the benefit applies only once, add approximately $6/month to the IVIM effective rate.

Step-by-step: switching without a gap in medication

1. Check your current IVIM dose and remaining supply. Log in to your IVIM account or review your last shipment label to confirm your current dose of semaglutide or tirzepatide and how many weeks remain. IVIM bundles are prepaid, so you own the medication already delivered.

2. Start your PlexusDx intake one week before your final IVIM dose. Complete the online intake at PlexusDx. A licensed provider will review your information, current dose, and medical history. If approved, the provider writes a prescription for the same compound (semaglutide or tirzepatide) and determines the appropriate starting or continuation dose. PlexusDx does not guarantee dose continuity—the prescribing clinician makes an independent determination—but the intake form allows you to document your current regimen.

3. Coordinate shipment timing. PlexusDx ships via USPS Priority Mail; delivery typically takes 2–4 business days after the pharmacy dispenses. Request that your first PlexusDx shipment arrive within a few days of your last IVIM injection. If your IVIM supply runs out on a specific date, initiate the PlexusDx intake process at least 7–10 days in advance to allow time for provider review, pharmacy compounding, and transit.

4. Cancel your IVIM membership after your prepaid bundle is exhausted. Because IVIM medication bundles are prepaid, you do not need to cancel immediately. Use your remaining IVIM supply, then cancel the $75/month membership before the next billing cycle. Review IVIM's cancellation policy in your account settings or contact their support to confirm any notice requirements. No documentation of IVIM's refund or rollover policy was available as of September 4, 2026; confirm directly with IVIM if you have unused months in a prepaid bundle.

5. Adjust your dose schedule if the new provider prescribes a different starting dose. If the PlexusDx provider adjusts your dose—either to match your current IVIM dose or to follow a different titration protocol—follow the new prescription exactly. GLP-1 medications require careful dose escalation to minimize side effects; do not self-adjust.

Why people switch from IVIM Health

Upfront cost and cash-flow timing. IVIM's prepaid bundles require $600 (semaglutide) or $1,100 (tirzepatide) upfront, plus the first month's $75 membership fee, before the first dose ships. That is $675 or $1,175 out of pocket at enrollment. PlexusDx charges $189 or $289 for the first month only, no bulk prepayment, making the initial financial commitment lower.

Separation of medication and membership fees. IVIM bills medication and membership separately. If you pause or stop medication but forget to cancel the membership, you continue paying $75/month with no medication benefit. PlexusDx has no membership layer—the monthly fee covers medication, provider access, and shipping in a single line item.

Month-to-month flexibility. PlexusDx month-to-month plans allow you to pause or cancel after any monthly cycle without forfeiting a prepaid bundle. If your insurance situation changes, if you reach your goal weight, or if side effects require a break, you are not locked into a multi-month prepaid commitment.

Review and support visibility. PlexusDx holds a verified 4.3-star rating on Trustpilot with 79% of reviews at five stars and 83% at four stars or higher (captured September 9, 2026). IVIM Health has a Trustpilot profile, but detailed rating and review volume were not available in our capture as of September 4, 2026. Prospective switchers who prioritize transparent service feedback may weigh this asymmetry.

Where IVIM Health may still fit

Lower effective monthly rate for semaglutide if you can prepay and stay the full term. IVIM's 6-month semaglutide bundle, including membership, costs approximately $162.50 per month over six months (our calculation, assuming first-month-free membership repeats). PlexusDx month-to-month semaglutide costs $189. If you have the upfront cash, expect to stay on semaglutide for at least six months, and value the lower recurring rate, IVIM's prepaid structure delivers a cost advantage. PlexusDx's 6-month commitment ($149/month) is lower than IVIM's effective rate, but requires you to commit in advance; IVIM requires upfront cash, PlexusDx requires a forward commitment.

Tirzepatide cost advantage. IVIM's 6-month tirzepatide bundle costs approximately $245.83 per month (our calculation, including membership). PlexusDx month-to-month tirzepatide costs $289, and the 6-month commitment is $249. IVIM's effective rate is lower if you prepay and use all six months, though the difference narrows when compared to PlexusDx's 6-month commitment.

Existing multi-month commitment. If you are midway through an IVIM 6-month bundle, you have already paid for that medication. Switching immediately forfeits the prepaid cost unless IVIM offers a prorated refund (policy not documented as of September 4, 2026). In that case, finish your current IVIM bundle, then evaluate switching before the next renewal.

Choose IVIM Health if…

• You have $600–$1,100 available upfront and prefer the lowest possible effective monthly rate for semaglutide or tirzepatide over a 6-month horizon.
• You are confident you will stay on the same medication for at least six months and do not need month-to-month flexibility.
• You are comfortable managing two separate billing lines (medication bundle + membership) and will remember to cancel the membership if you stop medication.
• You are already midway through a prepaid IVIM bundle and want to exhaust your prepaid supply before considering alternatives.

Choose PlexusDx if…

• You prefer month-to-month flexibility with no upfront bulk payment—pay $189 or $289 for one month, then decide whether to continue.
• You want a single all-inclusive monthly rate (medication, provider access, shipping) with no separate membership fee to track or cancel.
• You value transparent service feedback and want to work with a provider that has a verified 4.3-star Trustpilot rating with 83% of reviews at four stars or higher.
• You want the option to commit to a multi-month plan (6-month semaglutide at $149/month, 6-month tirzepatide at $249/month) for a lower rate than IVIM's effective cost, without requiring the full sum upfront.
• You are exploring additional compounded options—oral semaglutide or tirzepatide capsules, or microdose GLP-1 protocols—that IVIM does not offer.

Methodology and freshness

IVIM Health pricing, plan structure, and membership terms were captured from the IVIM Health website on September 4, 2026. PlexusDx pricing and service details were verified on September 7, 2026. The 12-month cost calculations, effective monthly rates, and side-by-side comparisons in this article are our calculations, derived from the verified per-month and prepaid bundle figures using standard arithmetic. We assume IVIM's first-month-free membership benefit repeats with each new 6-month medication bundle; if the benefit applies only once per customer, IVIM's effective monthly rate rises by approximately $6. IVIM's cancellation, refund, and rollover policies were not documented in available sources; readers should confirm these directly with IVIM before enrolling or switching. PlexusDx review data (4.3 stars, 79% five-star, 83% four stars or higher) was captured from Trustpilot on September 9, 2026. IVIM Health has a Trustpilot profile, but detailed rating and volume data were not available in our capture. All prices apply to compounded semaglutide and tirzepatide injections; neither IVIM nor PlexusDx compounded medications are FDA-approved. Readers should confirm current pricing, eligibility, and shipment lead times at enrollment, as telehealth policies and compounding pharmacy capacity can shift.

Frequently Asked Questions

Can I transfer my current IVIM dose directly to PlexusDx?

PlexusDx providers review your intake independently and determine the appropriate dose based on your medical history and current regimen. You can document your current IVIM dose in the intake form, but the prescribing clinician makes the final decision. Dose continuity is not guaranteed—the provider may match your current dose, adjust it, or restart titration depending on clinical judgment.

What happens to my unused IVIM medication if I switch early?

IVIM medication bundles are prepaid, so you own the doses already delivered. Use your remaining supply on schedule, then start PlexusDx when that supply is exhausted. If you want to switch before finishing your IVIM bundle, contact IVIM support to ask about refund or prorated credit policies—these were not documented as of September 4, 2026.

Do I need to cancel my IVIM membership before starting PlexusDx?

No. You can run both simultaneously while transitioning. Once your IVIM medication is exhausted and your first PlexusDx shipment has arrived, cancel your IVIM membership to stop the $75/month charge. Review your IVIM account for any notice requirements or billing-cycle cutoffs.

How long does PlexusDx take to ship the first order?

After provider approval and prescription, the compounding pharmacy typically dispenses within 1–3 business days, then ships via USPS Priority Mail (2–4 business days in transit). Plan for 7–10 days total from intake submission to delivery. Start your intake at least one week before your final IVIM dose to avoid a gap.

Does PlexusDx offer the same first-month-free membership that IVIM does?

PlexusDx has no membership fee at all—month-to-month or multi-month. The single monthly charge covers medication, provider access, and shipping. IVIM charges $75/month membership separately from medication (first month free). Over time, PlexusDx's no-membership structure often offsets the difference in advertised medication rates.
