The short answer

GobyMeds sells compounded semaglutide injections exclusively in prepaid three-month bundles ranging from $299 to $499—per-month equivalents of $99.67 to $166.33, depending on dose tier—and requires the full bundle cost upfront. Tirzepatide starts at a $399 three-month prepaid starter bundle ($133 per month equivalent) then shifts to a $299 monthly refill for any dose. There is no first-month promotional rate: the same prepaid tier pricing repeats for every refill bundle, and patients who need dose increases must move to higher-priced tiers. Over 12 months, the total cost depends entirely on which tier(s) a patient occupies; low-dose semaglutide users who never titrate pay $1,196 annually ($99.67/month average), while those who titrate from starter through mid to high tiers pay $1,696 ($141.33/month). The advertised per-month figures are our calculation from the upfront bundle prices; the structure favors patients comfortable with prepayment and confident they will remain in a single low tier.

At-a-glance: GobyMeds pricing structure

All GobyMeds pricing captured from gobymeds.com/getting-started/pricing on September 4, 2026. Every bundle includes consultation, prescription, supplies, and overnight shipping. No membership fee.

Normalized 12-month cost: like-for-like comparison

To understand long-term treatment cost, we calculate total expenditure over 12 months under two scenarios: a patient who remains in one tier all year, and a patient who titrates through multiple tiers.

Scenario 1: Static tier (patient never titrates)

PlexusDx pricing current as of September 16, 2026; month-to-month billing, same price at every dose, no prepayment. GobyMeds pricing from September 4, 2026. All 12-month totals and monthly averages are our calculation.

For patients who remain in GobyMeds' low tier all year, the $1,196 annual cost is lower than PlexusDx's $2,268—a difference of $1,072, or $89.33 per month. However, that advantage depends on never needing more than 0.4 mg weekly and accepting $299 upfront every three months. GobyMeds does not offer a month-to-month semaglutide option, so patients cannot pause or cancel mid-bundle.

PlexusDx charges the same $189 per month whether a patient takes 0.25 mg or 2.4 mg; GobyMeds increases the per-month equivalent by $33 (mid tier) or $66.66 (high tier) as dose rises. For tirzepatide, PlexusDx undercuts GobyMeds' monthly refill rate by $10 per month ($289 vs. $299), a $120 annual difference.

Scenario 2: Titration through multiple tiers

Most patients titrate dose over time. The table below models a patient who starts in the starter tier and moves upward as their provider adjusts the prescription.

Titration scenario for semaglutide assumes one bundle each at starter, mid, and two at high tier. Tirzepatide assumes one starter bundle then nine monthly refills. All totals are our calculation.

Under titration, GobyMeds semaglutide costs $1,696 over 12 months ($141.33/month average)—still $572 less than PlexusDx, but the gap narrows as higher tiers come into play. GobyMeds tirzepatide, after the starter bundle, costs $3,090 annually ($257.50/month average), $378 less than PlexusDx. The tirzepatide advantage comes from the $399 starter bundle lowering the average across 12 months; once a patient is past month three, GobyMeds charges $299 monthly while PlexusDx charges $289 monthly, so PlexusDx's per-month cost is lower from month four onward.

Decision factors: prepaid savings vs. flexibility trade-offs

Where GobyMeds holds an advantage

Lower cost for low-dose, stable patients: A patient who never exceeds 0.4 mg weekly semaglutide pays $1,196 annually with GobyMeds vs. $2,268 with PlexusDx—a real $1,072 annual saving. That advantage is durable so long as the patient remains in the low tier and is comfortable with $299 upfront every quarter.

No monthly decision fatigue: Prepaid bundles eliminate the monthly renewal decision; once you pay, medication arrives automatically for three months.

All-inclusive overnight shipping: GobyMeds includes overnight shipping in every bundle, which may matter for patients in remote areas or those who value faster delivery.

Where the prepaid model introduces friction

Upfront capital requirement: Every semaglutide refill requires $299 to $499 upfront. Patients on tight monthly budgets may find the lump sum harder to manage than a $189 monthly charge, even if the per-month average is lower.

Dose-tier jumps penalize titration: Moving from 0.4 mg to 0.6 mg semaglutide increases the bundle cost by $100 (from $299 to $399), an immediate $33 per month jump. PlexusDx charges $189 whether the patient takes 0.25 mg or 2.4 mg, so titration never changes the invoice.

No mid-bundle exit: GobyMeds does not offer month-to-month semaglutide. If a patient experiences side effects in week two and wants to stop, they have already paid for 12 weeks. PlexusDx month-to-month billing lets patients pause or cancel at any renewal without forfeiting prepaid funds.

Tirzepatide refill rate higher than PlexusDx: After the $399 starter bundle, GobyMeds tirzepatide costs $299 per month—$10 more per month than PlexusDx's $289. The starter bundle lowers the 12-month average, but from month four onward the per-month cost is higher.

Choose GobyMeds if…

• You are confident you will remain on a low semaglutide dose (0.2–0.4 mg weekly) for at least a year, making the $1,196 annual cost a clear win.
• You prefer to prepay in $299 increments and value the automatic three-month shipment cycle over monthly flexibility.
• You have already tried GLP-1 medication elsewhere, know your stable dose, and do not anticipate needing to titrate into higher tiers.
• Overnight shipping is a priority and you are willing to pay the bundle structure to secure it.

Where PlexusDx fits for patients evaluating prepaid models

PlexusDx month-to-month billing—$189 for compounded semaglutide injection, $289 for compounded tirzepatide injection—costs more per month than GobyMeds' low-tier semaglutide but eliminates upfront capital requirements, dose-tier pricing, and multi-month commitment. The same $189 (or $289) applies whether a patient takes a starter dose or the highest maintenance dose, so titration never triggers a price increase. Patients can pause or cancel at any monthly renewal without forfeiting prepaid funds.

For patients who anticipate dose adjustments, prefer smaller monthly outlays over quarterly lump sums, or want the option to stop without financial penalty, PlexusDx's flat-rate model offers predictability and exit flexibility that prepaid bundles do not. For patients confident they will remain in GobyMeds' low tier all year, the $1,072 annual saving is real and should drive the decision.

Methodology and freshness

All GobyMeds pricing was captured from the company's public pricing page (gobymeds.com/getting-started/pricing) on September 4, 2026, 13:49:55 UTC. We did not complete a checkout flow; the figures reflect the rates published by GobyMeds at that date. PlexusDx pricing is current as of September 16, 2026. The 12-month totals, monthly averages, and per-month equivalents for prepaid bundles are our calculation. We contacted GobyMeds for clarification on dose-tier boundaries and refill policies but did not receive a response by publication; the dose ranges (0.2–0.4 mg, 0.6–1.5 mg, 1.9–2.3 mg) are taken directly from the published pricing page as of the capture date. Patients should confirm current pricing, dose-tier definitions, cancellation terms, and any promotional adjustments at checkout before committing to any bundle.

Frequently Asked Questions

Does GobyMeds charge the same price for every refill, or does it go up after the first bundle?

GobyMeds repeats the same bundle price for every refill within the same dose tier. The starter bundle for semaglutide costs $299 for three months, and the low-tier refill bundle also costs $299 for three months. If your provider increases your dose into the mid tier, the next bundle costs $399; if you later move to the high tier, the next bundle costs $499. There is no separate "first-month promotional rate"—the bundle price is stable within each tier.

Can I switch from a prepaid bundle to month-to-month billing with GobyMeds?

GobyMeds does not offer month-to-month billing for semaglutide; all semaglutide is sold in prepaid three-month bundles. Tirzepatide offers both a prepaid starter bundle ($399 for three months) and a monthly refill option ($299 per month) after the starter period. If flexible billing is a priority, providers like PlexusDx that bill month-to-month may be a better structural fit.

What happens if I need to stop GobyMeds medication in the middle of a three-month bundle?

GobyMeds requires full payment upfront for each three-month bundle. If you decide to stop treatment after one month, you have already paid for all three months. The company's refund and cancellation policies were not detailed on the public pricing page captured September 4, 2026; you should confirm those terms directly with GobyMeds before purchasing any bundle if mid-cycle exit is a concern.

Does PlexusDx ever charge more if I increase my semaglutide or tirzepatide dose?

No. PlexusDx charges $189 per month for compounded semaglutide injection and $289 per month for compounded tirzepatide injection, regardless of dose. Whether your provider prescribes 0.25 mg or 2.4 mg semaglutide, the price remains $189. This dose-invariant pricing eliminates the tier-jump cost increases that prepaid bundle models sometimes introduce when a patient titrates upward.

Which provider is cheaper over 12 months: GobyMeds or PlexusDx?

It depends on your dose trajectory. If you remain in GobyMeds' low semaglutide tier (0.2–0.4 mg weekly) all year, GobyMeds costs $1,196 vs. PlexusDx's $2,268—a $1,072 annual saving. If you titrate from starter through mid to high tiers, GobyMeds costs $1,696 vs. PlexusDx's $2,268—a $572 saving. For tirzepatide, GobyMeds costs $3,090 over 12 months (starter bundle plus nine monthly refills) vs. PlexusDx's $3,468—a $378 difference. The trade-off is upfront payment and commitment (GobyMeds) vs. monthly flexibility and dose-invariant pricing (PlexusDx).
