The short answer

Yes—for semaglutide three-month bundles. GobyMeds bills compounded semaglutide in three dose tiers: $299 for the low-dose tier (0.2–0.4 mg), $399 for the mid-dose tier (0.6–1.5 mg), and $499 for the high-dose tier (1.9–2.3 mg), each covering a three-month supply. Your quarterly charge increases by $100 every time your provider moves you to the next tier. Over 12 months, low-dose semaglutide costs $1,196, mid-dose costs $1,596 (+$400/year), and high-dose costs $1,996 (+$800/year from the low tier). GobyMeds' tirzepatide monthly plan is flat at $299/month for any dose. PlexusDx charges $189/month for semaglutide and $289/month for tirzepatide at every dose, with no tiers and no prepayment. This breakdown shows the arithmetic at each tier, the break-even points, and when predictable flat-rate billing matters more than low-dose savings.

At a glance: GobyMeds dose tiers vs. flat-rate pricing

GobyMeds prepaid equivalents are our calculation from three-month upfront bundles. All prices captured September 4, 2026 (gobymeds.com) and July 17–23, 2026 (plexusdx.com).

How GobyMeds dose tiers work

GobyMeds sells compounded semaglutide injections in three-month prepaid bundles, with each bundle assigned to a dose range. The starter and low-dose tier (0.2–0.4 mg) costs $299 upfront for three months. When your provider increases your dose to the mid-range (0.6–1.5 mg), your next three-month bundle costs $399. If you move to the high-dose tier (1.9–2.3 mg), the three-month cost rises to $499. Each jump adds $100 to your quarterly charge—$33.33/month in effective cost—regardless of where within the tier your actual dose falls. Overnight shipping, supplies, and the provider consultation are included; GobyMeds does not charge a separate membership fee.

GobyMeds' tirzepatide program uses a different structure: a monthly subscription billed at $299/month for any dose. There are no dose tiers for tirzepatide, so your price stays flat even as your dose climbs.

Both medications are compounded; they are not FDA-approved. 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. PlexusDx works with licensed 503A compounding pharmacies.

Twelve-month cost at each dose tier

Most GLP-1 patients titrate gradually across multiple dose levels over several months. To see the real expense, we calculate 12-month costs assuming you stay within a single tier for the full year. (In practice, many people spend part of the year in one tier and part in another; we address that scenario below.)

GobyMeds semaglutide (three-month bundles)

• Low-dose tier (0.2–0.4 mg): $299 × 4 quarters = $1,196/year ($99.67/month prepaid equivalent, our calculation)
• Mid-dose tier (0.6–1.5 mg): $399 × 4 quarters = $1,596/year ($133/month prepaid equivalent, our calculation)
• High-dose tier (1.9–2.3 mg): $499 × 4 quarters = $1,996/year ($166.33/month prepaid equivalent, our calculation)

Moving from low-dose to mid-dose adds $400/year; moving from mid-dose to high-dose adds another $400/year. If you begin in the low tier and reach the high tier, your total annual increase is $800.

PlexusDx semaglutide (month-to-month, every dose)

• $189/month × 12 = $2,268/year (same at 0.25 mg, 1.0 mg, 2.4 mg, or any dose in between)

GobyMeds tirzepatide (monthly, any dose)

• $299/month × 12 = $3,588/year

PlexusDx tirzepatide (month-to-month, every dose)

• $289/month × 12 = $3,468/year

Break-even analysis: when does flat-rate pricing cost less?

GobyMeds wins on low-dose semaglutide. At the low tier, GobyMeds costs $1,196/year versus PlexusDx at $2,268/year—a $1,072 annual advantage for GobyMeds. At the mid-dose tier, GobyMeds costs $1,596/year, still $672 less than PlexusDx. But at the high-dose tier, GobyMeds costs $1,996/year, only $272 less than PlexusDx.

If you expect to spend most of your time in the low- or mid-dose range and your provider has confirmed your target dose will stay within that bracket, GobyMeds' tiered pricing delivers measurable savings. If you anticipate reaching higher doses—or if you value predictable billing over chasing the lowest possible floor—PlexusDx's flat $189/month means no quarterly recalculations and no upward surprises.

For tirzepatide, PlexusDx costs $3,468/year versus GobyMeds at $3,588/year, saving you $120/year ($10/month). GobyMeds does not tier tirzepatide, so both programs offer dose-independent pricing; PlexusDx is slightly cheaper and bills month-to-month instead of requiring monthly recurring charges on a fixed schedule.

What happens when you titrate across tiers?

Most patients do not stay in one dose tier for the entire year. A typical semaglutide titration might start at 0.25 mg, climb to 0.5 mg after four weeks, reach 1.0 mg by week 12, and settle at 1.7 mg by month six. Under GobyMeds' structure, your first three-month bundle (covering 0.25–0.5 mg) would fall in the low-dose tier at $299. Your second bundle (0.5–1.0 mg) might span the low and mid tiers; if your dose crosses into mid-range, you pay $399 for the next three months. Your third and fourth bundles at 1.7 mg would cost $499 each.

In this scenario, your 12-month GobyMeds cost would be $299 (Q1) + $399 (Q2) + $499 (Q3) + $499 (Q4) = $1,696 (our calculation). PlexusDx would charge $189 × 12 = $2,268, a $572 difference in GobyMeds' favor. The gap narrows as you spend more months in higher tiers.

The trade-off: GobyMeds saves you money on the climb, but you lose the ability to predict your next bill until your provider confirms your dose tier. PlexusDx holds $189/month regardless of titration speed, side-effect-driven pauses, or late-stage dose adjustments.

Prepayment, cancellation, and month-to-month flexibility

GobyMeds requires $299, $399, or $499 upfront for each three-month semaglutide bundle. If you pause treatment, experience intolerable side effects, or decide to stop after six weeks, you have prepaid for medication you may not use. GobyMeds' cancellation and refund policies were not detailed on the public pricing pages captured September 4, 2026; confirm the policy at intake if early-stop flexibility matters to you.

PlexusDx bills month-to-month with no prepayment. You can pause or cancel before the next monthly charge without forfeiting future months. If you need to stop semaglutide after one month, you pay for one month.

Choose GobyMeds if…

• Your provider has advised that your target semaglutide dose will stay in the low or mid range (under 1.5 mg), and you expect to remain at that level for several months.
• You are comfortable prepaying $299–$499 every three months and accept that your next charge may rise by $100 if your dose increases.
• Upfront savings matter more than billing predictability, and you can absorb the liquidity cost of quarterly prepayment.
• You prefer overnight shipping as the default delivery speed (included in GobyMeds bundles).

GobyMeds' low-dose semaglutide tier delivers the lowest 12-month cost in this comparison for patients who stay below 0.5 mg. That advantage persists through the mid tier but shrinks as doses climb. If your clinical picture supports low-dose efficacy, GobyMeds' tiered structure rewards you.

Choose PlexusDx if…

• You want the same monthly price at 0.25 mg, 1.7 mg, 2.4 mg, or any other semaglutide dose—no recalculations, no tier surprises.
• You value month-to-month flexibility over prepaid quarterly bundles, especially if you are uncertain how your body will tolerate GLP-1 therapy or how quickly you will titrate.
• You prefer tirzepatide, where PlexusDx costs $289/month (every dose) versus GobyMeds' $299/month (every dose), saving $120/year.
• You want to avoid the liquidity cost of $299–$499 upfront charges every quarter and prefer paying one month at a time.

PlexusDx holds $189/month for semaglutide and $289/month for tirzepatide regardless of your dose. You know your cost on day one and on day 365. For patients who titrate to higher doses, reach maintenance quickly, or simply prefer predictable billing, PlexusDx eliminates dose-based pricing risk. The program works with licensed 503A compounding pharmacies and includes the provider visit, prescription, medication, and shipping in the single monthly charge—no membership fee, no separate consultation bill.
