The short answer

TrimRx's 12-month prepaid plan costs $2,218 for compounded semaglutide injection and $3,518 for compounded tirzepatide injection—$1,370 and $1,270 less, respectively, than paying month-to-month for a year. The six-month plan saves $1,052 and $952 versus monthly billing. Every prepaid plan requires full upfront payment and is non-refundable for unused medication or remaining months. If you're certain you'll continue treatment for the full term and can afford the lump sum, the prepaid tiers deliver measurable savings; if you want flexibility to pause or stop without forfeiting prepaid funds, month-to-month at $299 semaglutide or $399 tirzepatide is the safer structure despite the higher annual cost.

TrimRx plan options at a glance

All figures recorded at TrimRx checkout July 18, 2026. Prepaid per-month equivalents are our calculation. All plans include shipping; no membership fee. Same price at every dose.

Twelve-month cost comparison: month-to-month versus prepaid

To evaluate which structure costs less over a full year, we calculated the total paid under each plan assuming continuous treatment for twelve months.

Semaglutide

• Month-to-month: $299 × 12 = $3,588
• 3-month prepaid: $748 × 4 cycles = $2,992 (saves $596, or 16.6%)
• 6-month prepaid: $1,268 × 2 cycles = $2,536 (saves $1,052, or 29.3%)
• 12-month prepaid: $2,218 single charge (saves $1,370, or 38.2%)

Tirzepatide

• Month-to-month: $399 × 12 = $4,788
• 3-month prepaid: $1,068 × 4 cycles = $4,272 (saves $516, or 10.8%)
• 6-month prepaid: $1,918 × 2 cycles = $3,836 (saves $952, or 19.9%)
• 12-month prepaid: $3,518 single charge (saves $1,270, or 26.5%)

All 12-month totals and savings percentages are our calculation based on recorded per-plan pricing.

The 12-month prepaid plan delivers the lowest annual cost for both medications. If you renew a six-month plan twice instead, you pay $318 more over the year—still hundreds less than monthly billing, but the annual plan's edge is clear when the upfront capital is available.

What you commit to with each plan

TrimRx prepaid plans require the full payment upfront and are billed as a single transaction, not spread across the subscription period. According to terms recorded at checkout in July 2026, multi-month packages will not be refunded for unused medication or remaining months, and cancellation stops future charges only—it does not recoup prepaid funds.

Zero-percent financing is available through Klarna, Afterpay, or Affirm, which can divide the lump sum into installments, but TrimRx is not a party to those financing agreements; you enter a separate contract with the lender, and approval, terms, and fees (if any after promotional periods) are the lender's responsibility.

Month-to-month billing charges your payment method each cycle. You can cancel before the next billing date without forfeiting future months, making it the only structure that preserves optionality if your treatment plan changes, side effects emerge, or insurance coverage becomes available mid-year.

Advertised versus checkout pricing

TrimRx's website advertises $199 per month for semaglutide and $349 per month for tirzepatide. In a complete signup flow captured July 18, 2026, the checkout presented $299 and $399 month-to-month rates with no appearance of the advertised figures at any stage. We document both sets of numbers here; the $299 and $399 rates are the verified ongoing charges recorded at the point of purchase, while the $199 and $349 figures remain published on marketing pages. If you are considering TrimRx, confirm the applicable rate at your own checkout before committing, especially for prepaid plans where the total is charged immediately.

Decision factors: prepaid savings versus month-to-month flexibility

Prepaid plans offer lower effective monthly rates but require certainty

The 12-month plan's $1,370 semaglutide savings (or $1,270 tirzepatide savings) over monthly billing is significant if you are confident treatment will continue for a full year. The six-month plan captures most of that discount—$1,052 and $952, respectively—with half the upfront capital and half the commitment window. The three-month plan saves $596 and $516 but approaches the flexibility threshold where the dollar advantage may not justify the loss of optionality for some users.

All prepaid tiers assume stable tolerability, no insurance changes, no pregnancy, no contraindications that emerge during treatment, and no clinical decision to pause or switch medications. If any of those contingencies materialize, the prepaid amount is non-refundable.

Month-to-month preserves optionality at a higher annual cost

Paying $299 or $399 each month costs $1,370 or $1,270 more over twelve months than the annual plan, but every dollar spent buys one month of medication with no further obligation. If you stop after six months on the monthly plan, you've paid $1,794 semaglutide or $2,394 tirzepatide; if you'd prepaid the 12-month plan and stop at six months, you've paid $2,218 or $3,518 with no recourse for the unused half.

Month-to-month is the rational choice when treatment duration is uncertain, when cash flow makes large lump sums impractical, or when you want the ability to pause without financial penalty.

Same price at every dose, injection format only

TrimRx charges one flat rate per medication regardless of dose strength—common among telemedicine GLP-1 programs. Only injection formats are offered; no oral or microdose options appeared in the recorded checkout flow. Shipping is included in every plan tier, and there is no separate membership or consultation fee layered on top of the medication price.

Choose TrimRx month-to-month if…

• You want the freedom to stop, pause, or switch without forfeiting prepaid funds.
• You are early in treatment and unsure how you will tolerate the medication over many months.
• Large upfront payments strain your budget or emergency reserves.
• You prefer to pay as you go and accept the higher annual cost in exchange for optionality.

Choose a TrimRx prepaid plan if…

• You are certain you will continue treatment for the full plan term.
• You can afford the lump-sum payment (or secure zero-percent financing) without financial stress.
• Lowering your effective monthly rate is a priority, and you're comfortable trading flexibility for savings.
• You've already been on GLP-1 therapy for months, tolerate it well, and want to lock in a lower cost for the next period.

The 12-month plan delivers the steepest discount; the six-month plan captures most of the savings with half the commitment; the three-month plan offers modest savings with the shortest lock-in window.

Where PlexusDx fits in this decision

PlexusDx does not offer a 12-month prepaid option, so readers weighing TrimRx's annual plan against other providers will find that structure only at TrimRx. For month-to-month and shorter prepaid tiers, PlexusDx pricing is lower across the board:

PlexusDx pricing recorded July 18 and July 20, 2026. TrimRx pricing recorded July 18, 2026. PlexusDx prepaid per-month figures are billed monthly at the stated rate; TrimRx prepaid equivalents are our calculation of single upfront totals.

PlexusDx month-to-month is $110 per month less for semaglutide and tirzepatide. Over twelve months of month-to-month billing, that difference totals $1,320—nearly the same absolute savings as switching from TrimRx monthly to TrimRx's 12-month prepaid plan, but with no upfront lump sum and no forfeiture risk.

PlexusDx also offers compounded semaglutide oral capsules ($289 month-to-month) and a microdose injection protocol ($129 month-to-month), neither of which TrimRx provides. All PlexusDx plans include the provider visit, prescription, compounded medication, and shipping in the stated price; no separate fees apply.

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 (captured September 9, 2026; trustpilot.com/review/plexusdx.com).

Frequently Asked Questions

Does TrimRx refund unused months if I cancel a prepaid plan early?

No. TrimRx's terms state that multi-month packages will not be refunded for unused medication or remaining months. Cancellation stops future charges for month-to-month subscribers but does not recoup prepaid funds for users on three-, six-, or twelve-month plans.

Can I spread the cost of a TrimRx prepaid plan into monthly payments?

TrimRx offers zero-percent financing through Klarna, Afterpay, and Affirm, which can divide the prepaid total into installments. TrimRx is not a party to those financing agreements; approval, terms, and any fees after promotional periods are determined by the lender. You remain obligated for the full prepaid amount even if you stop treatment early.

Why does TrimRx advertise one price but charge another at checkout?

TrimRx's website advertises $199 per month for semaglutide and $349 for tirzepatide, but the checkout flow recorded in July 2026 presented $299 and $399 month-to-month with no appearance of the lower advertised figures. We documented both sets of numbers; confirm the applicable rate at your own checkout before purchasing.

Does the price per month change if my dose increases on a TrimRx plan?

No. TrimRx charges the same flat rate regardless of dose strength. Whether you are on the starting dose or a higher maintenance dose, the monthly or prepaid total remains constant for the medication you selected at enrollment.

How much do I save over a year by choosing TrimRx's 12-month plan instead of paying monthly?

The 12-month prepaid plan costs $2,218 for semaglutide and $3,518 for tirzepatide. Paying month-to-month for twelve months totals $3,588 semaglutide or $4,788 tirzepatide, so the annual plan saves $1,370 and $1,270 respectively. Those savings require full upfront payment and are non-refundable if you stop early.
