PlexusDx publishes this comparison and is one of the providers discussed. We use the same evidence rules for our own program and competing programs.

The short answer

PlexusDx undercuts TrimRx at every plan length we could verify side-by-side. TrimRx advertises semaglutide at $199/month on its blog, but at checkout on July 18, 2026, the month-to-month rate was $299—$110 higher than PlexusDx's $189 month-to-month price. The gap persists across 3-month and 6-month prepaid plans; over twelve months of 6-month cycles, PlexusDx costs $1,788 for semaglutide versus TrimRx's $2,536, a $748 difference. TrimRx offers a 12-month prepaid option ($2,218 semaglutide, $3,518 tirzepatide) that PlexusDx does not match, but that 12-month semaglutide total is still $430 more than PlexusDx's two 6-month cycles. Both programs use dose-flat pricing—every dose costs the same—so the advertised-versus-checkout discrepancy and the per-month floor are the only price variables that matter. Neither charges membership fees; both include shipping and provider visits. PlexusDx adds oral capsule formats and optional genetic testing; TrimRx is injections only. If you want the lowest cash price with no advertised-versus-actual surprises, the checkout-verified evidence favors PlexusDx.

At-a-glance comparison

Pricing verified July 18, 2026 and September 4, 2026. All figures are checkout-confirmed or documented at the respective sites.

Advertised versus checkout pricing

TrimRx advertises semaglutide at $199/month on its blog (captured September 4, 2026). At checkout on July 18, 2026, the month-to-month rate was $299—a $100 gap between the advertised figure and the price a buyer actually pays. TrimRx has advertised tirzepatide at various rates: the blog references tirzepatide "starting at $299/month" (captured September 4, 2026), the site had previously advertised $349, and at checkout on July 18, 2026, the month-to-month price was $399. These discrepancies mean you should verify the current checkout price before committing; the advertised rate may not carry through to payment.

PlexusDx lists semaglutide injection at $189/month and tirzepatide injection at $289/month with no advertised-versus-actual gap. The price shown on the product page is the price charged at checkout, confirmed July 18, 2026.

Like-for-like plan pricing and twelve-month totals

Both programs offer month-to-month, 3-month prepaid, and 6-month prepaid plans; TrimRx also offers a 12-month prepaid option. Below are the checkout-verified rates and the cost over twelve months for each matching plan length. All twelve-month totals are our calculation unless the program offers a single 12-month package.

Month-to-month (paid monthly, twelve successive months)

3-month plans (four cycles over twelve months)

6-month plans (two cycles over twelve months)

TrimRx offers a 12-month prepaid plan: $2,218 for semaglutide and $3,518 for tirzepatide (checkout verified July 18, 2026). PlexusDx does not offer a 12-month option. TrimRx's 12-month semaglutide plan is $430 more than two cycles of PlexusDx's 6-month plan ($2,218 versus $1,788), and the 12-month tirzepatide plan is $530 more than PlexusDx's two 6-month cycles ($3,518 versus $2,988). However, these are not matching plan lengths; the 12-month plan locks in supply and price for a full year, while cycling 6-month plans requires re-enrollment every six months.

What dose-flat pricing means in practice

Both PlexusDx and TrimRx use dose-flat pricing: every dose of semaglutide costs the same per month, and every dose of tirzepatide costs the same per month, regardless of milligram strength. Whether your clinician prescribes 0.25 mg, 1 mg, or 2.4 mg semaglutide, you pay the same monthly rate. This structure eliminates dose-escalation surcharges and makes budgeting straightforward. The only price variables are which molecule you use and which plan length you choose.

Dose-flat pricing is especially relevant during titration. Many patients start at a low dose and increase every four weeks until they reach a therapeutic or maintenance level. Under a dose-tiered model, each escalation would trigger a price increase. Under a dose-flat model, your monthly bill stays constant from the first 0.25 mg dose through maintenance at 2.4 mg (or higher, if your provider prescribes it and the pharmacy can compound it).

Billing and refund policies

PlexusDx and TrimRx both bill prepaid multi-month plans as a single upfront total. If you select TrimRx's 6-month semaglutide plan, you pay $1,268 at checkout (verified July 18, 2026); if you select PlexusDx's 6-month semaglutide plan, you pay $894 at checkout (verified July 18, 2026). Month-to-month plans charge each month separately.

TrimRx states explicitly that multi-month packages "will not be refunded for unused medication or remaining months" (verified July 18, 2026). Cancellation stops future charges but does not recover prepaid funds. The site notes that 0% financing is available through Klarna, Afterpay, and Affirm, though "TrimRx is not a party to those agreements" (verified July 18, 2026). If you finance a prepaid package and then stop treatment, you remain liable to the lender.

PlexusDx's current refund and cancellation terms should be confirmed at checkout. The general principle is the same: prepaid multi-month plans reduce the per-month cost in exchange for upfront commitment.

Included services and format options

Both programs include shipping and provider consultations in the monthly price; neither charges a membership fee (verified July 18, 2026). PlexusDx adds named PharmD support and an optional genetic testing add-on (verified July 18, 2026). The genetics panel analyzes how your body metabolizes GLP-1 and other medications, which can inform dose and molecule choice; it is not required and carries a separate fee.

PlexusDx offers semaglutide and tirzepatide in both injectable and oral capsule formats, plus a microdose GLP-1 injection option for maintenance (verified July 18, 2026). TrimRx offers compounded injections only (verified July 18, 2026). If you prefer oral administration or want to step down to a microdose after reaching goal weight, PlexusDx provides those pathways within the same program.

Review and transparency record

PlexusDx holds a 4.2-star rating on Trustpilot, with 76% of reviews at five stars and 81% at four stars or higher (captured September 4, 2026). TrimRx's review profile was not captured in the evidence packet; confirm current ratings on Trustpilot or similar platforms before committing to a prepaid plan.

TrimRx's advertised-versus-checkout pricing gap is a transparency concern. When the blog advertises $199 semaglutide and checkout shows $299, a prospective patient may budget incorrectly or feel misled. PlexusDx's advertised prices match checkout prices (verified July 18, 2026), eliminating that friction.

Choose PlexusDx if…

• You want the lowest verified month-to-month price for semaglutide ($189) or tirzepatide ($289) with no advertised-versus-actual gap.
• You prefer a 6-month prepaid plan and want to minimize twelve-month cost ($1,788 semaglutide, $2,988 tirzepatide over two cycles).
• You value format flexibility: injectable, oral, or microdose options within one program.
• You want optional genetic testing to inform dose and molecule choice.
• You prefer named PharmD support rather than general customer service.
• You appreciate pricing transparency—advertised price equals checkout price.

Choose TrimRx if…

• You want to prepay for twelve months in a single transaction and lock in supply for a full year ($2,218 semaglutide, $3,518 tirzepatide).
• You prefer injections and have no interest in oral or microdose formats.
• You are comfortable with TrimRx's no-refund policy for prepaid packages and can commit upfront without flexibility to exit early with a refund.
• You want to use third-party financing (Klarna, Afterpay, Affirm) to split the prepaid cost into installments, understanding that you remain liable to the lender even if you stop treatment.
• You have verified the current checkout price and confirmed it matches your budget, regardless of advertised rates.

Where PlexusDx fits in the dose-flat landscape

PlexusDx entered the compounded GLP-1 market with dose-flat pricing as a core principle. The $189 semaglutide month-to-month rate and $149 6-month rate are among the lowest checkout-verified prices in the cash-pay space (as of July 18, 2026). The program adds oral capsules, microdose maintenance, and genetics without charging a membership fee or splitting medication cost from consult fees. For patients who want predictable monthly costs, no advertised-versus-checkout surprises, and the option to switch formats mid-treatment, PlexusDx offers a clear value proposition. The absence of a 12-month plan may be a drawback for patients who want to lock in a full year at once, but two cycles of the 6-month plan still cost less than TrimRx's 12-month package and preserve the option to reassess every six months.

Frequently Asked Questions

Does TrimRx charge the advertised $199 semaglutide price at checkout?

At checkout on July 18, 2026, TrimRx's month-to-month semaglutide price was $299, not the $199 advertised on its blog (captured September 4, 2026). Verify the current checkout price before selecting a plan; advertised rates may not carry through to payment.

How much do I save with PlexusDx over twelve months on a 6-month plan?

PlexusDx's 6-month semaglutide plan costs $894 per cycle; two cycles total $1,788 over twelve months (our calculation). TrimRx's 6-month plan costs $1,268 per cycle, totaling $2,536 over twelve months. Over two 6-month cycles, PlexusDx saves $748 on semaglutide and $848 on tirzepatide.
