The short answer

GobyMeds sells compounded semaglutide injection in three-month bundles priced by dose tier: $299 upfront for starter or low-tier doses (0.2–0.4 mg), $399 for mid-tier doses (up to 0.6–1.5 mg), and $499 for high-tier doses (up to 1.9–2.3 mg). Every bundle is paid in full at the start of each quarter and covers provider consult, prescription, medication, supplies, and overnight shipping with no membership fee. Patients at maintenance doses renew the same tier every three months; over 12 months the low tier costs $1,196 total ($99.67/month prepaid equivalent), the mid tier $1,596 ($133/month), and the high tier $1,996 ($166.33/month). Tirzepatide is available as a $399 starter bundle or a $299/month ongoing plan.

The tier structure means your quarterly cost rises as your dose increases. If you remain on a stable maintenance dose, the prepaid-equivalent rate stays constant—but you commit $299–$499 every 90 days. Flat-rate programs that charge one price at every dose may cost less over 12 months if you reach higher doses quickly; GobyMeds' bundles can be more economical if you stay in the low tier or value overnight shipping and the simplicity of quarterly renewal.

Normalized 12-month cost: upfront bundles versus monthly billing

GobyMeds advertises per-month equivalents—$99.67, $133, $166.33—but every figure represents a three-month bundle paid upfront. To see true recurring cost, multiply the quarterly charge by four renewals:

  • Low tier (0.2–0.4 mg): $299 × 4 = $1,196 over 12 months ($99.67/month prepaid equivalent, our calculation).
  • Mid tier (0.6–1.5 mg): $399 × 4 = $1,596 over 12 months ($133/month prepaid equivalent, our calculation).
  • High tier (1.9–2.3 mg): $499 × 4 = $1,996 over 12 months ($166.33/month prepaid equivalent, our calculation).

PlexusDx charges a flat rate at every dose and bills monthly or by commitment period. Over 12 months, PlexusDx semaglutide injection costs $2,268 month-to-month, $2,028 with a three-month commitment ($169/month), or $1,788 with a six-month commitment ($149/month). The six-month plan is $408 less expensive than GobyMeds' low tier, $192 less than the mid tier, and $208 more expensive than the high tier over a full year (all comparisons are our calculation).

The crossover is dose-dependent. If you stabilize on 0.25 or 0.5 mg semaglutide and renew the GobyMeds low tier every quarter, you spend $1,196 in 12 months—$592 less than PlexusDx month-to-month and $240 less than the PlexusDx three-month plan, though still $408 more than the PlexusDx six-month rate (our calculation). If your provider titrates you to 2.4 mg and you renew the high tier, you spend $1,996 annually, which is $272 less than PlexusDx month-to-month but $208 more than the PlexusDx six-month commitment (our calculation).

What the bundles include and exclude

Every GobyMeds semaglutide bundle is all-inclusive: provider consult, prescription, compounded medication, injection supplies, and overnight shipping. There is no separate membership fee, no per-visit charge, and no shipping surcharge. You pay the tier price—$299, $399, or $499—and receive three months of medication delivered to your door (captured September 4, 2026, gobymeds.com/getting-started/pricing).

The supplied research does not document cancellation terms, partial refunds for unused months within a bundle, or whether a patient may pause between bundles without restarting intake. If you need flexibility to stop or skip a quarter, confirm the refund and pause policy at checkout.

GobyMeds tirzepatide: starter bundle and monthly plan

GobyMeds offers compounded tirzepatide injection in two formats: a $399 upfront starter bundle covering three months of starter-dose medication ($133/month prepaid equivalent), or a $299/month ongoing plan billed monthly and available at any dose. The monthly plan is the standard option after the starter phase; over 12 months it costs $3,588 total (our calculation, captured September 4, 2026).

PlexusDx tirzepatide injection is $289/month month-to-month ($3,468 over 12 months), $269/month with a three-month commitment ($3,228 annually), or $249/month with a six-month commitment ($2,988 annually)—all our calculation. The PlexusDx six-month plan is $600 less expensive than GobyMeds' monthly tirzepatide over a full year (our calculation).

Strengths of the GobyMeds model

  • Overnight shipping included: every bundle ships overnight at no extra charge, reducing the delay between order and first dose.
  • Predictable quarterly budgeting: one upfront payment every 90 days covers consult, medication, and supplies with no surprise fees.
  • Lower 12-month cost in the low tier: patients who remain on 0.25 or 0.5 mg semaglutide indefinitely spend $1,196 over 12 months (our calculation), less than many flat-rate month-to-month programs.
  • No membership fee: unlike platforms that layer on $20–$50/month membership charges, GobyMeds bundles are medication-only.

Limitations and trade-offs

  • Upfront capital requirement: $299–$499 due every quarter; no option to spread the cost across monthly installments.
  • Tier escalation: if your provider increases your dose from 0.5 mg to 1.0 mg, you move from the $299 low tier to the $399 mid tier on the next renewal—a 33% jump in quarterly cost (our calculation).
  • Higher annual cost at maintenance doses above 1.0 mg: patients on 1.7 or 2.4 mg semaglutide renew the $499 high tier, paying $1,996 over 12 months (our calculation)—$208 more than PlexusDx six-month ($1,788) and $32 less than PlexusDx three-month ($2,028).
  • Cancellation and refund terms not documented: the supplied research does not confirm whether unused months within a bundle are refundable or whether you may pause between renewals.
  • Compounded medication: GobyMeds dispenses compounded semaglutide and tirzepatide, which are not FDA-approved and are not reviewed by FDA for safety, effectiveness, or quality before marketing. A licensed clinician determines whether a prescription is appropriate for an individual patient. GobyMeds works with licensed 503A compounding pharmacies.

Choose GobyMeds if…

  • You anticipate remaining on a low maintenance dose (0.25–0.5 mg) long-term and want to lock in $1,196 annual spend (our calculation).
  • You value overnight shipping and prefer to pay in full every quarter rather than manage monthly billing.
  • You have the upfront capital to commit $299–$499 every 90 days and appreciate the simplicity of an all-inclusive bundle.

Over 12 months the six-month plan costs $1,788 total, $408 less than GobyMeds' low tier and $208 less than the high tier (our calculation). The month-to-month plan offers maximum flexibility with no prepayment and no penalty to pause or cancel. Every plan includes provider visit, prescription, compounded medication, and shipping in one transparent price, and PlexusDx holds a 4.3-star rating on Trustpilot with 79% of reviews at five stars and 83% at four stars or higher (captured September 9, 2026, trustpilot.com/review/plexusdx.com).
