The short answer

10Rx charges $299 every three months for compounded semaglutide with B12, and $450 every three months for compounded tirzepatide with B12—prepaid quarterly with no membership fees, no add-on charges, and the same price across all available strengths. The quarterly structure includes medication, clinician evaluation, next-day shipping, and support. While the per-month arithmetic works out to $99.67 for semaglutide and $150 for tirzepatide when prepaid quarterly, the actual billing is a single $299 or $450 charge every three months. The quarterly prepaid model delivers a lower effective monthly rate than most month-to-month competitors, but it requires committing three months of cash up front and lacks the flexibility to pause or adjust between refills without forfeiting the prepaid period.

Confirm totals at checkout before committing.

Breaking down the quarterly prepaid model

10Rx operates on a prepaid quarterly package model. You pay $299 or $450 up front, and the service ships three months of medication at once. The package price includes the clinician evaluation, all available strengths at the same cost, next-day shipping, and ongoing support—no membership fees, no per-visit charges, no add-on costs.

The effective monthly rate when prepaid quarterly is $99.67 for semaglutide and $150 for tirzepatide (our calculation). That arithmetic is straightforward—divide the quarterly charge by three—but the billing reality is a single $299 or $450 payment every three months, not a true monthly subscription.

The quarterly structure creates predictability: you know the total cost for three months, and the same price applies at every dose strength. It also removes the monthly payment friction—one charge per quarter, done. But it also means you commit the full amount up front, and if you need to pause, adjust, or stop mid-quarter, you've already paid for the remaining weeks.

What the cash-pay package covers

The $299 semaglutide and $450 tirzepatide quarterly charges are all-inclusive. The package covers:

  • Medication: Compounded semaglutide or tirzepatide injection with B12, three-month supply shipped at once.
  • Clinician evaluation: A licensed provider reviews your intake and determines whether a prescription is appropriate.
  • Next-day shipping: Included in the package price, no separate shipping fee.
  • Support: Access to the 10Rx support team throughout your quarterly cycle.

There are no membership fees, no per-visit charges, and no separate consultation costs. The flat quarterly price is the same whether you're starting at a low dose or moving to a higher strength later—dose increases do not increase the package price.

12-month cost comparison: quarterly prepaid vs. month-to-month

To compare 10Rx's prepaid quarterly model with month-to-month and other commitment structures, we calculate the total cost over 12 months. All figures below are our calculation unless otherwise noted.

Provider & Medication Billing Model Effective Monthly 12-Month Total
10Rx semaglutide injection (with B12) Prepaid quarterly ($299 every 3 months) $99.67 $1,196
PlexusDx semaglutide injection Month-to-month $189 $2,268
PlexusDx semaglutide injection 6-month commitment $149 $1,788
10Rx tirzepatide injection (with B12) Prepaid quarterly ($450 every 3 months) $150 $1,800
PlexusDx tirzepatide injection Month-to-month $289 $3,468
PlexusDx tirzepatide injection 6-month commitment $249 $2,988

All 12-month totals and effective monthly figures are our calculation. 10Rx figures calculated as quarterly charge × 4 quarters. PlexusDx figures calculated as monthly rate × 12 months. 10Rx pricing captured September 4, 2026; PlexusDx pricing captured July 17–23, 2026. Confirm all rates at checkout.

10Rx's prepaid quarterly model delivers the lowest effective monthly cost for both semaglutide ($99.67/month, $1,196 over 12 months) and tirzepatide ($150/month, $1,800 over 12 months) among the options above. PlexusDx's month-to-month rates are higher—$189 for semaglutide, $289 for tirzepatide—but carry no prepayment requirement and allow you to pause or cancel at any time without forfeiting unused weeks. PlexusDx's 6-month commitment options ($149/month semaglutide, $249/month tirzepatide) fall between 10Rx's quarterly prepaid rate and PlexusDx's month-to-month rate, requiring a longer upfront commitment but still costing more over 12 months than 10Rx's quarterly packages.

The prepayment trade-off: lower rate, less flexibility

The quarterly prepaid model creates a clear trade-off. Prepaying three months at once locks in a lower effective monthly rate, but it also locks in your commitment. If you experience side effects in week four and want to pause, or if your insurance coverage changes mid-quarter, you've already paid for the remaining weeks. Month-to-month billing costs more per month, but it lets you stop, adjust, or switch without forfeiting prepaid time.

The evidence does not document 10Rx's cancellation or refund terms. If you need to cancel mid-quarter, confirm with 10Rx whether any portion of the prepaid charge is refundable or whether the charge covers the full three-month period regardless of when you stop.

Same price at every dose: the flat-strength policy

10Rx charges the same quarterly package price across all available dose strengths. Whether you're starting at a low dose or escalating to a higher maintenance strength, the $299 semaglutide or $450 tirzepatide quarterly charge remains constant. This contrasts with some competitors that tier pricing by dose or charge more as you move to higher strengths.

The flat-strength policy simplifies budgeting: your quarterly cost is the same throughout your treatment, regardless of dose changes. It also means you pay the full package price even at the lowest starting dose, where some month-to-month providers may charge less initially.

No membership fees, no add-on charges

10Rx does not charge a separate membership fee, consultation fee, or shipping fee. The $299 or $450 quarterly package price is the only charge. This all-inclusive structure is simpler than competitors that layer a membership fee (often $49–$99/month) on top of medication costs, but it also means there's no lower-cost access tier if you only need occasional support or want to pause medication while retaining provider access.

Evidence and limitations

The quarterly prepaid structure, inclusions, and flat-strength pricing policy are verified from 10Rx's primary pricing page (captured September 4, 2026). The specific dollar totals—$299 for semaglutide, $450 for tirzepatide—rely on secondary corroboration, as 10Rx's pricing page verifies the structure and inclusions but suppresses the numeric totals in the indexed evidence. Confirm these figures at checkout before committing.

No cancellation, refund, or mid-quarter adjustment terms are documented in the captured evidence. If these terms matter to your decision, confirm them directly with 10Rx before your first quarterly payment.

Review evidence: A Trustpilot profile for 10Rx was not located as of September 4, 2026. A Reddit search identified a launch discussion thread but no attributable negative themes or volume trends in the indexed results.

Choose 10Rx if…

  • You want the lowest effective monthly rate and are comfortable committing three months of cash up front.
  • You value simplicity: one all-inclusive quarterly charge, no membership fees, no separate add-ons.

  • You value transparent, pay-as-you-go billing where each month's charge reflects only that month's service.

Where PlexusDx fits

PlexusDx offers compounded semaglutide injection at $189/month month-to-month and compounded tirzepatide injection at $289/month month-to-month, with no membership fees and the same price at every dose. The month-to-month rate is higher than 10Rx's prepaid quarterly equivalent, but it carries no prepayment requirement—you pay only for the current month, and you can pause or cancel at any time without forfeiting unused weeks. PlexusDx also offers 3-month ($169/month semaglutide, $269/month tirzepatide) and 6-month ($149/month semaglutide, $249/month tirzepatide) commitment options that reduce the effective monthly rate while still costing more over 12 months than 10Rx's quarterly packages but less than PlexusDx's month-to-month rate.

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).

Frequently Asked Questions

Does 10Rx charge a monthly subscription or a quarterly package?

10Rx charges a quarterly package: $299 every three months for semaglutide, $450 every three months for tirzepatide. You prepay the full three-month amount at once, not a monthly subscription. The effective monthly rate when prepaid quarterly is $99.67 for semaglutide and $150 for tirzepatide (our calculation), but the actual billing is one charge every three months.

Are there any membership fees or hidden charges with 10Rx?

No. The $299 semaglutide or $450 tirzepatide quarterly package price includes medication, clinician evaluation, next-day shipping, and support. There are no separate membership fees, consultation charges, or add-on costs. The quarterly package price is the only charge you pay.

Does the 10Rx price increase when I move to a higher dose?

No. 10Rx charges the same quarterly package price across all available dose strengths. Whether you start at a low dose or escalate to a higher maintenance strength, the $299 semaglutide or $450 tirzepatide quarterly charge remains constant throughout your treatment.

Can I cancel 10Rx mid-quarter and get a refund?

The evidence does not document 10Rx's cancellation or refund terms. Since you prepay the full three-month package up front, confirm with 10Rx directly whether any portion of the prepaid charge is refundable if you need to cancel mid-quarter, or whether the charge covers the full period regardless of when you stop.

How does 10Rx's prepaid quarterly model compare to month-to-month billing?

10Rx's prepaid quarterly model delivers a lower effective monthly rate—$99.67 for semaglutide, $150 for tirzepatide—but requires committing three months of cash up front. Month-to-month billing costs more per month but lets you pause or cancel at any time without forfeiting prepaid weeks. The trade-off is cost savings versus flexibility.
