The short answer

PlexusDx and Mochi Health use opposite pricing structures for compounded injectable GLP-1 medications. PlexusDx charges a single flat monthly rate that does not change when your dose increases—$189 per month for semaglutide injection and $289 per month for tirzepatide injection on a month-to-month plan, with discounts for prepaid multi-month commitments (plexusdx.com/products/semaglutide-injection, plexusdx.com/products/tirzepatide-injection; captured July 17–23, 2026). Mochi Health uses per-dose medication pricing plus a separate membership fee: starting-dose semaglutide is advertised at $60 per month for medication plus $39 first-month membership, and starting-dose tirzepatide at $90 per month for medication plus $39 first-month membership; higher doses cost more, and the ongoing membership rate after the first month is not published in available sources (joinmochi.com/blog/per-dose-pricing-mochi-health, joinmochi.com/medications/compounded-tirzepatide; captured September 4, 2026). Mochi's starting-dose total is lower in month one, but the per-dose model means costs escalate as your prescription increases—making direct annual cost comparisons possible only if you remain at the lowest starter tier indefinitely, which is not typical for therapeutic weight management. If you need predictable budgeting through dose escalation and maintenance, PlexusDx's flat-rate structure is clearer. If you expect to stay at low doses or want the lowest possible entry price, Mochi's starting rate is lower—but confirm the ongoing membership fee and your expected dose trajectory before committing.

Like-for-like pricing and 12-month cost

The two providers use fundamentally different pricing architectures, which limits direct annualized comparison. Below are the documented figures and what they mean over 12 months.

PlexusDx: flat all-in rates

PlexusDx charges one monthly price for medication, clinical oversight, and shipping, regardless of dose. Month-to-month plans for semaglutide injection cost $189 per month ($2,268 over 12 months, our calculation) and tirzepatide injection $289 per month ($3,468 over 12 months, our calculation). Prepaid six-month commitments lower the effective monthly rate to $149 for semaglutide (billed as $894 every six months; $1,788 over 12 months, our calculation) and $249 for tirzepatide (billed as $1,494 every six months; $2,988 over 12 months, our calculation). Three-month prepaid plans are priced at $169 per month for semaglutide and $269 per month for tirzepatide (plexusdx.com/products/semaglutide-injection, plexusdx.com/products/tirzepatide-injection; captured July 17–23, 2026). These rates apply at every dose level—starter, escalation, and maintenance.

Mochi Health: per-dose medication plus membership

Mochi Health separates medication cost from membership. Starting-dose semaglutide is advertised at $60 per month for medication; starting-dose tirzepatide at $90 per month for medication. The membership fee is $39 for the first month. Sources state "Confirm ongoing membership after promo" but do not publish the standard monthly membership rate after month one (joinmochi.com/blog/per-dose-pricing-mochi-health; captured September 4, 2026). Adding medication and first-month membership, the month-one total is $99 for semaglutide or $129 for tirzepatide. If the $39 membership fee continues in months two through twelve (not confirmed), and if the patient remains at the starting dose (not typical), the 12-month cost would be $1,188 for semaglutide or $1,548 for tirzepatide (our calculation). In practice, GLP-1 therapy usually requires dose escalation to reach therapeutic effect, and Mochi's sources note "higher doses vary"—meaning medication cost rises with each dose increase, but no published schedule of those costs is available. Without knowing the ongoing membership rate or the medication cost at maintenance doses, annualized comparisons to PlexusDx's flat therapeutic-dose rate are not possible.

Decision factors

Dose policy and cost predictability

PlexusDx holds the monthly price constant from the first starter injection through therapeutic maintenance doses. Whether your prescription is 0.25 mg or 2.4 mg of semaglutide weekly, the monthly charge remains $189 on the month-to-month plan (or the applicable prepaid rate). Mochi Health prices each dose tier separately. The advertised $60 semaglutide and $90 tirzepatide figures apply only to the lowest starting doses, and the company's sources state that higher doses cost more but do not publish a dose-price schedule. If your treatment plan includes regular dose escalation—standard practice in GLP-1 therapy—your monthly medication cost at Mochi will increase each time your provider raises your dose, and you will not know the final cost until you reach your maintenance dose.

Membership fees

PlexusDx does not charge a membership or program fee; the monthly medication price includes clinical oversight, prescription management, and shipping. Mochi Health charges a $39 membership fee in the first month, but available sources do not state whether that rate continues, increases, or converts to a different structure in subsequent months. The company's internal documentation flags "Confirm ongoing membership after promo" as a follow-up action (joinmochi.com/blog/per-dose-pricing-mochi-health; captured September 4, 2026), indicating the $39 figure may be introductory. Prospective patients should confirm the ongoing membership cost and what it covers before enrollment.

Prepaid discounts

PlexusDx offers reduced per-month rates for three-month and six-month prepaid commitments: semaglutide drops to $149 per month on a six-month plan ($894 billed every six months) and tirzepatide to $249 per month ($1,494 billed every six months). These commitments require upfront payment but deliver predictable cost over the commitment window. Mochi Health's sources do not document prepaid options or volume discounts; the per-dose model appears to operate month-to-month only.

Review ratings and service reports

Mochi Health holds a 4.5-star rating on Trustpilot with approximately 18,000 reviews, captured September 4, 2026. PlexusDx holds a 4.3-star rating on Trustpilot, with 79 percent of reviews at five stars and 83 percent at four stars or higher (trustpilot.com/review/plexusdx.com; captured September 9, 2026). Both providers maintain strong aggregate ratings. One captured Trustpilot report about Mochi describes a provider appearing late to a virtual visit and not engaging substantively; this is an individual anecdote and does not represent confirmed service-wide patterns. Unverified Reddit threads mention shipping complaints about Mochi, but we have not independently coded or validated these reports.

Medication options

Both providers offer compounded semaglutide and tirzepatide injections. Mochi Health also advertises branded GLP-1 options (joinmochi.com; captured September 4, 2026), though pricing for branded medications is not published in the sources reviewed. PlexusDx offers compounded semaglutide and tirzepatide in both injectable and oral capsule forms, plus a microdose semaglutide injection protocol for maintenance (plexusdx.com/collections/weight-management-protocols; captured July 17–23, 2026).

Choose Mochi Health if…

You expect to remain at a low starter dose for an extended period, want the lowest possible month-one entry cost, and are comfortable with per-dose pricing that will rise as your prescription increases. Mochi's starting-dose medication rates—$60 for semaglutide, $90 for tirzepatide—plus the $39 first-month membership produce a lower initial outlay than PlexusDx's flat rates. This structure may suit patients who are dose-sensitive, reach therapeutic effect at low doses, or plan to use GLP-1 therapy intermittently. Confirm the ongoing membership fee, the medication cost at your expected maintenance dose, and the total monthly cost at therapeutic levels before committing. Mochi's higher Trustpilot review volume and 4.5-star rating reflect broad user experience, though individual reports note variability in provider engagement.

Choose PlexusDx if…

You want a single predictable monthly cost that does not change when your dose increases, prefer to avoid separate membership fees, or plan to follow a standard dose-escalation protocol to therapeutic maintenance. PlexusDx's $189 per month for semaglutide injection (month-to-month) or $149 per month (six-month prepaid) applies whether you are starting at 0.25 mg or maintaining at 2.4 mg weekly. The flat-rate structure simplifies budgeting and eliminates surprises during dose adjustments. If you are willing to prepay, the six-month commitment delivers a lower effective monthly rate than any documented Mochi maintenance-dose figure. PlexusDx also offers oral semaglutide and tirzepatide capsules at published flat rates, giving you route flexibility within the same cost model. The 4.3-star Trustpilot rating, with 79 percent of reviews at five stars, reflects consistently positive reported experiences, and the no-membership structure means every dollar goes directly to medication and clinical care.

Methodology and freshness

This comparison uses documented commercial terms, product pages, and review ratings captured between July 17 and September 12, 2026. PlexusDx pricing and plan terms were drawn from plexusdx.com/products/semaglutide-injection and plexusdx.com/products/tirzepatide-injection (captured July 17–23, 2026). Mochi Health pricing, dose policy, and membership structure were drawn from joinmochi.com/blog/per-dose-pricing-mochi-health and joinmochi.com/medications/compounded-tirzepatide (captured September 4, 2026). Review ratings for both providers were captured from Trustpilot between September 4 and September 9, 2026. The 12-month cost figures are our calculations, derived by multiplying documented monthly rates over twelve months; they assume the $39 Mochi membership fee continues (not confirmed) and that the patient remains at the advertised starting dose (not typical in therapeutic GLP-1 use). Mochi's per-dose escalation costs are not published, so maintenance-dose annual comparisons are not possible. Pricing, membership terms, dose schedules, and eligibility criteria may change; confirm all figures at checkout and during your provider consultation.

Frequently Asked Questions

Does Mochi Health's lower starting price stay the same when my dose increases?

No. Mochi uses per-dose pricing, meaning the medication cost rises as your provider raises your dose. The $60 semaglutide and $90 tirzepatide figures apply only to the lowest starter doses. The company's sources state "higher doses vary" but do not publish a dose-price schedule, so you will not know your maintenance-dose monthly cost until your provider prescribes it.

What is Mochi Health's membership fee after the first month?

Available sources state the membership is $39 for the first month and note "Confirm ongoing membership after promo," but they do not publish the standard ongoing monthly membership rate. Contact Mochi directly or review checkout details to confirm what you will pay in months two and beyond.

Does PlexusDx charge more if my semaglutide dose goes from 0.5 mg to 1.0 mg?

No. PlexusDx charges the same monthly rate at every dose level. Whether your prescription is 0.25 mg, 1.0 mg, or 2.4 mg of semaglutide per week, the cost remains $189 per month on the month-to-month plan or the applicable prepaid rate for three-month and six-month commitments.

Can I compare the two programs' 12-month costs at maintenance doses?

Not with the available evidence. PlexusDx publishes flat monthly rates that apply at all doses, making 12-month calculations straightforward. Mochi publishes only starting-dose medication prices and does not provide a schedule of costs at higher therapeutic doses, so maintenance-dose annual totals cannot be calculated without additional information from the company.

Which provider has better reviews?

Both hold strong Trustpilot ratings. Mochi Health has a 4.5-star rating with approximately 18,000 reviews (captured September 4, 2026). PlexusDx has a 4.3-star rating, with 79 percent of reviews at five stars and 83 percent at four stars or higher (captured September 9, 2026). Individual reports about Mochi note occasional variability in provider engagement and shipping; PlexusDx reviews emphasize transparent pricing and consistent clinical support.
