The short answer
IVIM Health's cash-pay model splits cost into two pieces: a prepaid medication bundle (four or six months) and a separate $75-per-month membership fee. For compounded semaglutide, the advertised $100-per-month equivalent requires $600 upfront for six months of medication, plus membership billed monthly; with the first membership month free, the effective 12-month cost is $2,025, or $168.75 per month (our calculation). For compounded tirzepatide, a six-month bundle is $1,100 upfront ($183.33/month equivalent, prepaid), yielding a 12-month cost of $3,025 or $252.08 per month with membership. That structure delivers a lower total than many competitors if you stay the full year, but you bear upfront payment risk and sacrifice monthly flexibility. Month-to-month alternatives—such as PlexusDx's $189 semaglutide or $289 tirzepatide with no membership and no prepayment—cost more per shipment but eliminate commitment and simplify budgeting. The right choice depends on your cash position, confidence in tolerating the medication, and preference for predictable monthly charges versus bulk savings.

Breaking down IVIM Health's cash-pay structure
IVIM Health separates medication cost from ongoing service. You prepay for a four- or six-month supply of compounded semaglutide or tirzepatide, then pay a $75 membership fee each month (the first membership month is free). The advertised per-month figures—$100 for semaglutide, $183.33 for tirzepatide—apply only when you commit to the six-month bundle and exclude the membership fee (ivimhealth.com/glp1-pricing/, captured September 4, 2026).
For compounded semaglutide, the six-month medication bundle costs $600 upfront; purchasing two bundles over 12 months totals $1,200 in medication charges. Add 11 months of membership at $75 (the first month is free), and the 12-month cost is $2,025, or an effective $168.75 per month (our calculation). For compounded tirzepatide, two six-month bundles cost $2,200; with 11 months of membership the 12-month total is $3,025, or $252.08 per month (our calculation).
IVIM Health also offers four-month bundles—$499 for semaglutide ($124.75/month equivalent, prepaid), $900 for tirzepatide ($225/month equivalent, prepaid)—but those yield a higher per-month rate and require three purchases to cover a year, so most cash-pay patients gravitate toward the six-month option if they are confident in tolerating the medication (ivimhealth.com/glp1-pricing/, captured September 4, 2026).
Like-for-like 12-month cost comparison
Because IVIM Health bundles medication in advance and bills membership separately, a fair comparison requires calculating total outlays over 12 months and dividing by 12 to derive an effective monthly rate. The table below shows that arithmetic for IVIM Health's six-month bundles and PlexusDx's month-to-month plans.

All derived figures are our calculation. IVIM Health pricing captured September 4, 2026 (ivimhealth.com/glp1-pricing/); PlexusDx pricing captured July 17, 2026 (plexusdx.com). IVIM Health membership calculation assumes first month free, then $75 × 11 months.
Over a full year, IVIM Health's prepaid model delivers a lower total cost for both compounds—$243 less for semaglutide, $443 less for tirzepatide (our calculation)—but you must front six months of medication cost ($600 or $1,100) and commit to staying on the program. If you stop early, pause for side effects, or switch medications, you bear the financial risk of unused months. PlexusDx's month-to-month structure costs more in aggregate but lets you stop or change anytime without forfeiting a prepaid balance, and every dose tier costs the same $189 or $289 with no membership fee.

What the membership fee covers
IVIM Health's $75-per-month membership (first month free) includes ongoing clinician messaging, dose adjustments, and access to both compounded and brand-name GLP-1 options (ivimhealth.com/glp1-pricing/, captured September 4, 2026). That fee is billed separately from the prepaid medication bundles, so even in months when you already hold medication, the membership charge recurs. If you value frequent check-ins or anticipate switching between compounds, the separate service layer may justify the extra line item. If you prefer simplicity and rarely contact support, a single all-in monthly charge—such as PlexusDx's $189 or $289 that includes provider oversight, prescription, medication, and shipping—may be easier to budget and track.
Decision factors: prepaid savings versus monthly flexibility
Upfront commitment and cash flow
IVIM Health's six-month semaglutide bundle requires $600 at checkout; tirzepatide requires $1,100. That upfront outlay secures a lower effective monthly rate but demands liquid cash and confidence that you will tolerate the medication for at least six months. If your first dose causes nausea severe enough to stop, or if your provider advises switching compounds, you have prepaid for months you may not use. PlexusDx's month-to-month billing spreads the cost evenly and lets you pause or stop anytime; the higher per-shipment price is the trade-off for that liquidity and optionality.
Two-part billing versus all-in pricing
Separating medication from membership means two charges each month after your first: the prorated share of your prepaid bundle (which you already paid) and the $75 membership fee. That structure is transparent but introduces tracking overhead—did I already renew my six-month supply? Am I in the free membership month?—and complicates cost comparisons across programs. An all-in monthly rate collapses medication, provider access, and shipping into a single predictable charge, which simplifies budgeting and subscription management.
Dose escalation and titration
Both IVIM Health and PlexusDx adjust doses as you titrate upward; neither charges extra when you move from, say, 0.5 mg to 1.0 mg semaglutide. IVIM Health's prepaid bundles cover the full titration schedule within the bundle period; PlexusDx holds the same $189 or $289 rate at every dose tier. If you expect a slow, cautious ramp or plan to stay at a maintenance dose for months, the cost arithmetic favors IVIM Health's prepaid model; if you anticipate frequent changes, pauses, or switching between semaglutide and tirzepatide, month-to-month flexibility may prove more economical in practice.
Choose IVIM Health if…
You have $600–$1,100 in liquid cash to commit upfront, are confident you will tolerate the medication for at least six months, and prioritize the lowest possible total 12-month cost. IVIM Health's prepaid bundles deliver an effective monthly rate $20–$37 below PlexusDx (our calculation) if you stay the full year. The separate $75 membership fee adds ongoing clinician access and the option to switch to brand-name GLP-1s mid-program, which may appeal if you value frequent check-ins or foresee moving off compounded medications. Confirm dose availability in your state and review the bundle refund or pause policy before committing; prepaid structures shift financial risk from the provider to the patient, so understanding your exit options is essential.
Choose PlexusDx if…
You prefer predictable monthly charges with no upfront commitment, want the freedom to stop or change medications without forfeiting a prepaid balance, or value administrative simplicity—one charge, one shipment, one support channel. PlexusDx's $189 semaglutide and $289 tirzepatide rates are higher per month than IVIM Health's six-month equivalents but include provider visit, prescription, medication, shipping, and dose adjustments in a single line item with no membership fee. Every dose costs the same, so titration never triggers a price jump. You can pause, skip a month, or switch compounds without financial penalty. PlexusDx holds a 4.3-star rating on Trustpilot, with 79% of reviews at five stars and 83% at four stars or higher (captured September 9, 2026; trustpilot.com/review/plexusdx.com), and works with licensed 503A compounding pharmacies. If cash flow matters more than bulk savings, or if you are uncertain about tolerating GLP-1s long-term, month-to-month billing reduces risk and preserves optionality.
Methodology and freshness
We captured IVIM Health's pricing from ivimhealth.com/glp1-pricing/ on September 4, 2026. Prepaid bundle costs ($600 semaglutide six-month, $1,100 tirzepatide six-month), membership fees ($75/month, first month free), and medication options (compounded semaglutide, compounded tirzepatide) are documented as published on that date. PlexusDx pricing was captured July 17, 2026 from product pages on plexusdx.com. We performed 12-month cost arithmetic by multiplying prepaid bundles by the number of cycles required to reach 12 months, adding 11 months of IVIM Health membership (first month free), and dividing total outlay by 12; those derived figures are labeled "our calculation." Advertised per-month equivalents for IVIM Health's prepaid bundles exclude the membership fee and are labeled as prepaid throughout. All compounded medications are not FDA-approved; FDA does not review compounded drugs before marketing for safety, effectiveness, or quality. A licensed clinician determines whether a prescription is appropriate for an individual patient. We revisit commercial telehealth pricing monthly; if you notice a discrepancy, email research@plexusdx.com with the URL and current figure.
Frequently Asked Questions
Does IVIM Health's advertised $100 per month semaglutide rate include the membership fee?
No. The $100-per-month figure is the prepaid equivalent of the six-month medication bundle ($600 upfront) and excludes the $75-per-month membership fee. With the first membership month free, the effective 12-month cost is $2,025, or $168.75 per month when both medication and membership are included (our calculation, captured September 4, 2026).
What happens if I stop IVIM Health's program before my six-month bundle runs out?
IVIM Health's refund and pause policies are not detailed in the public pricing page we captured. Contact IVIM Health directly before purchasing to understand whether unused months of a prepaid bundle are refundable, transferable, or forfeited if you stop early. Prepaid structures generally shift financial risk to the patient, so clarifying exit terms is essential before committing $600 or $1,100 upfront.
Can I switch from semaglutide to tirzepatide mid-bundle at IVIM Health?
IVIM Health's membership includes access to both compounded and brand-name GLP-1 options, but the pricing page does not specify whether switching compounds mid-bundle requires purchasing a new bundle or adjusting the existing one. Ask IVIM Health's intake team whether a compound switch forfeits your remaining prepaid months or allows a prorated credit toward the new medication bundle (ivimhealth.com/glp1-pricing/, captured September 4, 2026).
Does PlexusDx charge more when I move to a higher semaglutide dose?
No. PlexusDx holds the same $189-per-month rate at every semaglutide dose tier, from 0.25 mg through 2.4 mg (and higher if prescribed). Tirzepatide remains $289 per month across all dose levels. Dose adjustments never trigger a price increase, so your budget stays predictable as you titrate upward (plexusdx.com, captured July 17, 2026).
Which program saves more money over 12 months for tirzepatide?
IVIM Health's six-month tirzepatide bundles total $3,025 over 12 months when medication ($2,200) and 11 months of membership ($825, first month free) are combined, yielding an effective rate of $252.08 per month. PlexusDx's month-to-month tirzepatide costs $3,468 over 12 months ($289 × 12), or $289 per month. IVIM Health saves $443 in total if you complete the full year (our calculation), but you must prepay $1,100 upfront and forfeit flexibility; PlexusDx spreads the cost evenly with no commitment.
