The short answer

Peak Wellness runs a straightforward GLP-1 telehealth model: two injectables (semaglutide, tirzepatide), physician oversight through Dr. TelX, four 503A pharmacy partners, and transparent month-to-month rates of $249 and $349. At 12 months on standard billing, semaglutide costs $2,988 and tirzepatide costs $4,188. PlexusDx month-to-month rates are $189 and $289, yielding $720/year less on either compound. Peak's 6-month prepaid tirzepatide rate (≈$233/month equivalent, our calculation) undercuts PlexusDx's 6-month rate ($249/month) by $16/month; Peak's 6-month semaglutide equivalent (≈$165/month) is $16/month more than PlexusDx's 6-month rate ($149/month). PlexusDx adds three formats Peak does not offer: oral semaglutide ($289 month-to-month, $249 6-month), oral tirzepatide ($349 month-to-month, $279 6-month), and microdose GLP-1 ($129 month-to-month). Peak includes free next-day air and a dose assistant; PlexusDx includes an optional genetics test ($99 for members) and named Doctor of Pharmacy support. Both charge only after provider approval, cancel anytime, and work with licensed 503A compounding pharmacies.

Sources: Peak Wellness pricing verified September 1, 2026 across three independent captures (PlexusDx comparison page, Peak Wellness website, third-party verification). PlexusDx pricing verified September 1, 2026. Per-month equivalents for Peak Wellness 6-month plans are our calculation; Peak publishes only the prepaid total.

12-month cost comparison: month-to-month billing

Month-to-month billing offers maximum flexibility—you pay as you go, cancel anytime, and adapt dosing or compound choice without penalty. Here is what a full year costs at each program's standard ongoing rates:

Compound Peak Wellness (12 months) PlexusDx (12 months) Difference
Semaglutide injection $2,988 $2,268 $720 less at PlexusDx
Tirzepatide injection $4,188 $3,468 $720 less at PlexusDx

Calculation: Peak Wellness $249/month × 12 = $2,988 semaglutide; $349/month × 12 = $4,188 tirzepatide. PlexusDx $189/month × 12 = $2,268 semaglutide; $289/month × 12 = $3,468 tirzepatide. Both programs charge the same price at every dose.

Prepaid rates: where lower committed-term rates appear

Both programs offer prepaid packages that reduce the per-month equivalent when you commit upfront. Peak Wellness publishes 3-month and 6-month prepaid totals; we calculated the per-month equivalent for comparison. PlexusDx publishes per-month rates for prepaid terms.

Plan Peak Wellness PlexusDx Per-month comparison
Semaglutide 3-month $597 total (≈$199/mo our calc) $169/mo ($507 total) PlexusDx $30/mo less
Tirzepatide 3-month $837 total (≈$279/mo our calc) $269/mo ($807 total) PlexusDx $10/mo less
Semaglutide 6-month $990 total (≈$165/mo our calc) $149/mo ($894 total) PlexusDx $16/mo less
Tirzepatide 6-month $1,396 total (≈$233/mo our calc) $249/mo ($1,494 total) Peak $16/mo less

Note: Peak Wellness publishes only the prepaid total for 6-month plans; the per-month equivalent is our calculation. PlexusDx publishes per-month rates for all prepaid terms. Peak Wellness's 6-month tirzepatide rate is the only pricing point where Peak undercuts PlexusDx. PlexusDx holds the advantage on month-to-month, 3-month, and 6-month semaglutide.

Decision factors: what differs beyond price

Format variety

Peak Wellness offers two injectables: semaglutide and tirzepatide. PlexusDx offers five protocols: semaglutide injection, tirzepatide injection, semaglutide oral capsules, tirzepatide oral capsules, and microdose GLP-1 injection. Oral protocols cost $289–$349 month-to-month at PlexusDx and drop to $249–$279 at the 6-month rate. Microdose GLP-1 costs $129/month and is designed for maintenance or low-dose tolerance testing. If you want oral administration or a sub-clinical microdose option, PlexusDx provides those routes; if you need only standard-dose injectables, both programs supply them.

Clinical support and genetics

Peak Wellness assigns board-certified physicians through Dr. TelX, with review promised within 24 hours and 24/7 clinical support available. PlexusDx assigns a named Doctor of Pharmacy and offers an optional genetics test ($99 for members, $298 standalone) that includes a free check-in with the PharmD. The test does not predict medication efficacy or select your compound—that decision remains with the provider—but it identifies genetic variants that may inform dosing, side-effect risk, or contraindications. Neither program includes genetics in the base price; PlexusDx makes it optional, Peak does not offer it.

Shipping and supplies

Peak Wellness includes free next-day air on all orders and supplies syringes with every shipment. PlexusDx includes shipping and supplies in the all-inclusive monthly charge; shipping speed is not separately advertised. Both programs supply injection materials at no extra cost.

Prepaid refund terms

Both programs allow you to pause, skip, or cancel through your account portal or by email. Peak Wellness states that changes take effect at the next billing cycle. How Peak handles unused months in prepaid packages—whether they issue pro-rata refunds or credit toward future months—is not documented in the terms we captured. PlexusDx states "cancel anytime" but similarly does not detail prepaid refund mechanics in the pricing pages. Confirm prepaid refund or credit terms at checkout or during intake if you plan to commit upfront.

Pharmacy and provider networks

Peak Wellness works with four named 503A compounding pharmacies: Emerald Compounding (Tampa, FL), Epiq Scripts (Richardson, TX), Southend Pharmacy (Houston, TX), and AbsoluteRX (Lutz, FL). All medical consultations and prescriptions flow through Dr. TelX. PlexusDx works with licensed 503A compounding pharmacies; specific pharmacy partners are not individually named on public pages. Both programs operate under the 503A compounding framework, meaning medications are made to order after a provider writes a prescription.

Choose Peak Wellness if…

  • You want 6-month prepaid tirzepatide at the lowest per-month equivalent we found (≈$233/month vs. PlexusDx $249/month).
  • You value free next-day air shipping as a separately highlighted service feature.
  • You prefer board-certified physician oversight through Dr. TelX and 24/7 clinical support over PharmD-led care.
  • You need only injectable semaglutide or tirzepatide and do not require oral or microdose options.

Choose PlexusDx if…

  • You want the lowest month-to-month rate on semaglutide ($189 vs. $249, saving $720/year) or tirzepatide ($289 vs. $349, saving $720/year).
  • You want oral GLP-1 capsules instead of injections, or you want to test a microdose protocol ($129/month) for maintenance or side-effect mitigation.
  • You value optional genetics testing ($99 for members) with a free PharmD check-in to inform dosing or flag genetic contraindications.
  • You want named Doctor of Pharmacy support rather than rotating physician teams.
  • You want the lowest 3-month or 6-month semaglutide rates ($169 and $149/month prepaid vs. Peak's ≈$199 and ≈$165).

Methodology and freshness

We captured Peak Wellness pricing from three independent sources on September 1, 2026: the PlexusDx comparison page, Peak Wellness's own website pricing tables, and a third-party verification. All three sources agreed on month-to-month rates ($249 semaglutide, $349 tirzepatide) and prepaid totals ($597/$837 for 3 months, $990/$1,396 for 6 months). PlexusDx pricing was verified from the same comparison page and live product pages on September 1, 2026. We calculated per-month equivalents for Peak Wellness's 6-month plans because Peak publishes only the prepaid total, not a monthly figure; those calculations are labeled throughout. All 12-month cost projections are our calculation using standard ongoing rates. We report only standard ongoing rates and prepaid totals; we excluded all limited-time offers and other discount arithmetic per our methodology standard. Both programs charge the same price at every dose, so cost comparisons hold across titration schedules. Capture dates, sources, and calculation steps are documented in the Sources section below.

Frequently Asked Questions

Does Peak Wellness charge a membership fee?

No. Peak Wellness charges no membership fee. You pay only the monthly medication price ($249 semaglutide, $349 tirzepatide) or the prepaid package total if you choose a 3-month or 6-month plan. PlexusDx also charges no membership fee.

Can I cancel Peak Wellness or PlexusDx anytime?

Yes. Both programs allow you to cancel anytime with no cancellation fee. Peak Wellness states that changes take effect at the next billing cycle. If you prepay for 3 or 6 months, confirm the refund or credit policy for unused months before committing, as that detail is not published on public pricing pages.

Does PlexusDx offer oral GLP-1 capsules?

Yes. PlexusDx offers oral semaglutide capsules ($289 month-to-month, $249 at 6 months) and oral tirzepatide capsules ($349 month-to-month, $279 at 6 months). Peak Wellness offers only injectable semaglutide and tirzepatide. Oral protocols may suit individuals who prefer not to inject or who experience injection-site reactions.

What is PlexusDx's microdose GLP-1 protocol?

PlexusDx's microdose GLP-1 protocol costs $129/month and delivers semaglutide at sub-clinical doses—typically used for maintenance after reaching goal weight or for individuals testing tolerance before escalating to standard doses. Peak Wellness does not offer a microdose option. A licensed provider determines whether microdose therapy is appropriate for your clinical situation.

Are compounded semaglutide and tirzepatide FDA-approved?

No. 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.
