The short answer

GobyMeds wins on low-dose semaglutide if you prepay three months at a time and stay under 0.4 mg—$299 upfront yields a $99.67-per-month effective rate (captured September 4, 2026; gobymeds.com/getting-started/pricing). That advantage narrows as dose increases: the mid tier (up to 0.6–1.5 mg) costs $399 upfront for a $133 effective monthly rate, and the high tier (up to 1.9–2.3 mg) costs $499 upfront for $166.33 per month. PlexusDx charges $189 per month on a month-to-month basis for compounded semaglutide injection at any dose—no prepayment, no tier jumps—or $149 per month on a six-month commitment, still dose-independent. For tirzepatide, GobyMeds offers only a $299-per-month plan at any dose (no prepaid option), while PlexusDx charges $289 per month month-to-month or $249 per month on a six-month commitment. The decision hinges on whether you value the lowest possible prepaid semaglutide rate with dose restrictions or prefer flat-rate simplicity and stronger tirzepatide economics.

GobyMeds pricing captured September 4, 2026 (gobymeds.com/getting-started/pricing); competitive context captured July 17–23, 2026 (plexusdx.com/pages/glp-1-alternatives); PlexusDx pricing current as of September 13, 2026. All prepaid per-month figures are our calculation based on total upfront cost divided by commitment length.

GobyMeds pricing structure: dose tiers and prepayment

GobyMeds sells compounded semaglutide and tirzepatide injections through a tiered, prepaid structure for semaglutide and monthly billing for tirzepatide. Semaglutide bundles are paid three months at a time and sorted by dose ceiling:

  • Low tier (0.2–0.4 mg): $299 upfront for three months = $99.67 per month effective
  • Mid tier (up to 0.6–1.5 mg): $399 upfront for three months = $133 per month effective
  • High tier (up to 1.9–2.3 mg): $499 upfront for three months = $166.33 per month effective

Each bundle includes consultation, prescription, supplies, and overnight shipping (gobymeds.com/getting-started/pricing, captured September 4, 2026). A patient who starts at a lower dose and titrates up will move to the next tier and pay the corresponding upfront amount every three months. Over twelve months, a patient remaining in the low tier pays $1,196 total (four bundles × $299), a mid-tier patient pays $1,596 (four bundles × $399), and a high-tier patient pays $1,996 (four bundles × $499)—all our calculation.

Tirzepatide is offered only as a monthly subscription at $299 per month for any dose, billed monthly with no prepayment option. Over twelve months that totals $3,588 (our calculation).

PlexusDx pricing structure: flat rate at every dose

PlexusDx charges a single rate for compounded semaglutide or tirzepatide injection regardless of dose. Semaglutide is $189 per month on a month-to-month basis, $169 per month on a three-month commitment, or $149 per month on a six-month commitment. Tirzepatide is $289 per month month-to-month, $269 per month on a three-month commitment, or $249 per month on a six-month commitment. No membership fee, no tier jumps, no prepayment requirement on the month-to-month option. Over twelve months a patient on semaglutide pays $2,268 month-to-month or $1,788 on the six-month plan; a patient on tirzepatide pays $3,468 month-to-month or $2,988 on the six-month plan (all our calculation).

Twelve-month cost comparison: semaglutide

Because GobyMeds uses dose tiers and prepaid bundles while PlexusDx offers month-to-month and multi-month flat rates, the twelve-month totals depend on dose trajectory and commitment preference:

Scenario GobyMeds (prepaid 3-mo bundles) PlexusDx (MTM) PlexusDx (6-mo commitment)
Low dose (0.2–0.4 mg) all year $1,196
($99.67/month effective)
$2,268
($189/month)
$1,788
($149/month)
Mid dose (up to 0.6–1.5 mg) all year $1,596
($133/month effective)
$2,268
($189/month)
$1,788
($149/month)
High dose (up to 1.9–2.3 mg) all year $1,996
($166.33/month effective)
$2,268
($189/month)
$1,788
($149/month)

All twelve-month totals and effective monthly rates are our calculation. GobyMeds pricing assumes four three-month bundles per year at the stated tier; PlexusDx pricing assumes consistent monthly billing or a single six-month commitment renewed once.

GobyMeds delivers the lowest absolute cost if you remain in the low tier for the full year. At mid and high doses, PlexusDx's six-month commitment beats GobyMeds' prepaid bundles, and PlexusDx's month-to-month rate is higher than GobyMeds mid and high tiers but offers the flexibility to pause or cancel without forfeiting a prepaid bundle.

Twelve-month cost comparison: tirzepatide

GobyMeds offers tirzepatide only as a monthly subscription at $299 per month (any dose), which totals $3,588 over twelve months (our calculation). PlexusDx charges $289 per month month-to-month ($3,468 per year, our calculation), $269 per month on a three-month commitment ($3,228 per year, our calculation), or $249 per month on a six-month commitment ($2,988 per year, our calculation). PlexusDx wins at every commitment level, saving $120 per year month-to-month or $600 per year on the six-month plan relative to GobyMeds.

Service scope and logistics

GobyMeds includes consultation, prescription, medication, supplies, and overnight shipping in every bundle (gobymeds.com/getting-started/pricing, captured September 4, 2026). The company operates as a compounded-GLP-1 specialist and does not publish a broader formulary. A Trustpilot profile exists for GobyMeds (trustpilot.com/review/gobymeds.com, captured September 4, 2026), but rating and review volume were not captured in the indexed pass, so we cannot report aggregate sentiment or compare service quality to competitors on that dimension.

PlexusDx similarly bundles provider visit, prescription, compounded medication, and shipping into a single monthly charge with no separate membership fee. 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). PlexusDx works with licensed 503A compounding pharmacies and ships medication in temperature-controlled packaging; delivery timing is not instant but typically arrives within a few business days of approval.

Broader competitive context

Other compounded-GLP-1 providers captured in July 2026 include:

  • Eden: $99 medication fee plus a required $99-per-month membership, totaling $198 per month for semaglutide or $298 per month for tirzepatide (plexusdx.com/pages/glp-1-alternatives, captured July 17–23, 2026).
  • Embody: $299 per month for semaglutide, $349 per month for tirzepatide, no membership fee.
  • Peak Wellness: $249 per month for semaglutide, $349 per month for tirzepatide, no membership fee.
  • Found: $289 per month cash-pay for semaglutide, $359 per month for tirzepatide; "from $99" figures refer to an insurance track, not cash pricing.

Within this field, GobyMeds' prepaid low-tier semaglutide bundle ($99.67 effective per month) is the lowest advertised cash rate for patients who stay under 0.4 mg and are comfortable prepaying. PlexusDx's six-month semaglutide rate ($149 per month) is lower than Eden's ongoing cost ($198), Embody's rate ($299), and Peak Wellness ($249), and PlexusDx's tirzepatide six-month rate ($249) undercuts every listed competitor except Eden's medication-plus-membership structure ($298 total).

Choose GobyMeds if…

  • You expect to remain at a low semaglutide dose (0.2–0.4 mg) for an extended period and can prepay $299 every three months without financial strain.
  • You value overnight shipping and are willing to accept dose-tier pricing in exchange for the lowest possible prepaid rate at lower doses.
  • You do not require tirzepatide or are comfortable paying $299 per month for it on a monthly billing cycle.

Choose PlexusDx if…

  • You want the same price at every dose—no tier jumps when you titrate up.
  • You prefer month-to-month flexibility or are willing to commit to six months for a lower rate without prepaying the entire period upfront.
  • You are considering tirzepatide and want a lower monthly cost than GobyMeds offers ($249 or $289 vs. $299).
  • You value a provider with a published Trustpilot rating (4.3 stars, 83 percent four-star-or-higher) and want transparency on service quality.

What about oral semaglutide or microdose options?

GobyMeds does not publish oral semaglutide or microdose GLP-1 offerings in the captured pricing (gobymeds.com/getting-started/pricing, September 4, 2026). PlexusDx offers oral semaglutide capsules at $289 per month month-to-month, $269 per month on a three-month commitment, or $249 per month on a six-month commitment, and a microdose semaglutide injection protocol at $129 per month for patients seeking a lower-dose maintenance option after initial weight loss. Patients considering oral or microdose routes should confirm availability and eligibility directly with each provider, as clinical appropriateness varies by patient history and current weight-management phase.

Methodology and freshness

GobyMeds pricing was captured September 4, 2026, from the company's published pricing page (gobymeds.com/getting-started/pricing) and includes plan structure, upfront amounts, dose tiers, and inclusions (consultation, prescription, supplies, overnight shipping). PlexusDx pricing is current as of September 13, 2026, and reflects the canonical rate card provided in company documentation. Competitive context (Eden, Embody, Found, Peak Wellness) was captured July 17–23, 2026, from plexusdx.com/pages/glp-1-alternatives. All twelve-month totals and effective monthly rates are our calculation, derived by multiplying the stated monthly or bundle cost by the number of billing cycles in a year. Trustpilot data for PlexusDx was captured September 9, 2026; GobyMeds' Trustpilot profile was confirmed to exist but rating and volume were not indexed. We advise confirming current pricing, dose availability, and prepayment terms at checkout, as telehealth providers may adjust rates or launch new plans between publication and your enrollment date.

Frequently Asked Questions

Does GobyMeds charge less than PlexusDx for semaglutide?

GobyMeds charges less if you stay in the low tier (0.2–0.4 mg) and prepay three months at a time—$299 upfront yields a $99.67 effective monthly rate vs. PlexusDx's $189 month-to-month or $149 six-month. At mid and high doses, PlexusDx's six-month commitment ($149/month at any dose) beats GobyMeds' prepaid mid tier ($133 effective) and high tier ($166.33 effective) over twelve months.

Can I pay monthly with GobyMeds for semaglutide?

No. GobyMeds sells semaglutide only in prepaid three-month bundles ($299, $399, or $499 upfront depending on dose tier, captured September 4, 2026). Tirzepatide is available on monthly billing at $299 per month. PlexusDx offers true month-to-month billing for both semaglutide ($189) and tirzepatide ($289) with no prepayment requirement.

Which provider is cheaper for tirzepatide?

PlexusDx is cheaper at every commitment level. PlexusDx charges $289 per month month-to-month or $249 per month on a six-month commitment; GobyMeds charges $299 per month with no prepaid option (captured September 4, 2026). Over twelve months PlexusDx saves $120 month-to-month or $600 on the six-month plan, our calculation.

What happens if I need to increase my semaglutide dose on GobyMeds?

You move to the next tier and pay the higher upfront amount on your next three-month bundle. For example, if you start in the low tier ($299 for 0.2–0.4 mg) and titrate to 0.6 mg, your next bundle costs $399 for the mid tier. PlexusDx charges the same rate at every dose, so titration does not trigger a price increase.

Are GobyMeds and PlexusDx medications FDA-approved?

No. Both providers dispense compounded semaglutide and tirzepatide, which 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. Patients should confirm compounding-pharmacy credentials and state licensure with any provider before enrolling.
