The short answer

Amble offers compounded semaglutide injection at an advertised first-month rate of $179/month (standard refill rate to be confirmed at checkout) and compounded tirzepatide injection at $289/month for the 2.5–5 mg starter tier or $329/month for the 7.5–15 mg higher-dose tier, with no separate membership or service fee. PlexusDx charges a flat $189/month for semaglutide across all doses and $289/month for tirzepatide across all doses. Amble's advertised first-month semaglutide rate is $10/month less expensive than PlexusDx; Amble's low-dose tirzepatide tier matches PlexusDx at $289/month, but Amble's high-dose tirzepatide tier is $40/month more expensive. Both programs bill monthly with all-inclusive pricing. Amble's tirzepatide cost depends on your dose; PlexusDx's does not.

Breaking down Amble's pricing structure

Semaglutide: advertised first-month rate of $179/month

Amble advertises a first-month rate of $179 for compounded semaglutide injection regardless of dose. That rate includes the medication, clinician support, and shipping, with no separate membership or service fee. The standard refill rate is not documented in the pricing source reviewed and should be confirmed at checkout. Over 12 months, if the $179 rate applied to all months, Amble semaglutide would cost $2,148 (our calculation: $179 × 12). PlexusDx semaglutide is $189/month month-to-month at every dose, or $2,268 over 12 months (our calculation: $189 × 12). Amble's advertised first-month semaglutide rate is $10/month less expensive than PlexusDx's standard month-to-month rate.

Tirzepatide: $289/month (low dose) or $329/month (high dose)

Amble uses a two-tier tirzepatide pricing model. The starter or low-dose tier (2.5–5 mg weekly) is $289/month; the higher-dose tier (7.5–15 mg weekly) is $329/month. Both rates are all-inclusive with no membership fee. PlexusDx charges a flat $289/month month-to-month for tirzepatide across all dose levels, from 2.5 mg through 15 mg.

If you remain in Amble's low-dose tier (2.5–5 mg), the monthly cost ties PlexusDx at $289, and the 12-month total is $3,468 for both programs (our calculation: $289 × 12). If you move to Amble's high-dose tier (7.5–15 mg), the monthly cost rises to $329, and the 12-month total climbs to $3,948 (our calculation: $329 × 12)—$480 more per year than PlexusDx's flat $3,468 annual tirzepatide cost.

No membership fee, monthly billing

Both Amble and PlexusDx charge $0 for membership or service fees. Both bill monthly for a one-month supply. Neither program advertises hidden fees or separate shipping charges in the pricing sources we reviewed.

12-month cost comparison (month-to-month billing)

Medication Amble (12 months) PlexusDx (12 months) Difference
Semaglutide injection $2,148 (if $179/mo applies to all months; refill rate TBD) $2,268 Amble first-month rate $120/yr lower if sustained
Tirzepatide injection (low dose, 2.5–5 mg) $3,468 $3,468 Tied
Tirzepatide injection (high dose, 7.5–15 mg) $3,948 $3,468 PlexusDx $480/yr lower

All 12-month figures are our calculation (monthly rate × 12). Neither program offers multi-month discounts or prepay options in the evidence reviewed. Amble tirzepatide cost depends on your prescribed dose tier; PlexusDx tirzepatide is one flat rate regardless of dose.

Decision factors: what the pricing reveals

Amble's semaglutide advantage depends on refill pricing

Amble's advertised first-month semaglutide rate is $10/month lower than PlexusDx, with the same all-inclusive structure and no membership fee. If semaglutide is your medication and the $179 rate applies to all months, Amble delivers a clear $120 annual saving compared to PlexusDx. Confirm the ongoing refill rate at checkout to ensure the advertised rate persists beyond the first month.

Amble's tirzepatide structure depends on your dose path

Amble's two-tier tirzepatide model means your cost changes with your dose. If you remain in the 2.5–5 mg range—common during titration or maintenance—your monthly cost matches PlexusDx at $289. If you advance to the 7.5–15 mg range to reach your target dose, Amble's monthly cost rises to $329, making PlexusDx $40/month less expensive at that stage. Over a 12-month period at the higher tier, PlexusDx saves $480 compared to Amble.

Most patients do not stay at the lowest tirzepatide dose indefinitely; clinical titration protocols often increase the dose every four weeks until the patient reaches an effective maintenance dose or the maximum tolerated dose. If your provider anticipates you will move beyond 5 mg weekly, the $329 Amble tier becomes relevant, and PlexusDx's flat $289 rate offers greater cost predictability.

What's included and what's not documented

Both Amble and PlexusDx advertise all-inclusive pricing with no membership fee. Amble's pricing was captured from a frequently-asked-questions page hosted on Canva (https://amblefaq-glp1support.my.canva.site/) on September 4, 2026. The source does not provide detailed breakdowns of included services (for example, the number of clinician visits, whether labs are covered, or explicit shipping terms), and cancellation or refund policies are not documented in the pricing materials we reviewed. We recommend confirming service inclusions, cancellation terms, and final pricing at checkout before enrolling.

PlexusDx pricing includes the online provider visit, prescription, compounded medication at every dose, and shipping, with no hidden fees. Cancellation is available at any time with no penalty, and no refills ship after cancellation.

Frequently Asked Questions

Does Amble charge a membership fee in addition to the medication cost?

No. Amble's advertised pricing (first-month semaglutide rate of $179/month, $289/month or $329/month for tirzepatide depending on dose) is all-inclusive with no separate membership or service fee, according to the FAQ page captured September 4, 2026.

Why does Amble's tirzepatide price increase from $289 to $329?

Amble uses a two-tier tirzepatide pricing structure. The $289/month rate applies to the 2.5–5 mg weekly dose range (starter or low-dose tier). The $329/month rate applies to the 7.5–15 mg weekly dose range (higher-dose tier). Your provider determines your dose and tier based on clinical response and tolerability.

How does PlexusDx tirzepatide pricing work across different doses?

PlexusDx charges a flat $289/month month-to-month for tirzepatide injection regardless of dose—whether you are prescribed 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg weekly. The price does not change when your provider adjusts your dose up or down. That rate includes the provider visit, prescription, medication, and shipping.

Is Amble's $179 semaglutide rate a first-month promotion or the standard price?

The $179/month semaglutide rate is presented as an advertised rate in Amble's FAQ, with no explicit indication of whether it applies only to the first month or to all refills, based on the evidence captured September 4, 2026. We recommend confirming at checkout whether the rate applies to all months or only the first, and asking for the ongoing refill rate if different.

Can I switch from semaglutide to tirzepatide or vice versa within the same program?

Both Amble and PlexusDx offer compounded semaglutide and compounded tirzepatide. Whether you can switch medications, and whether switching changes your billing or eligibility, depends on your provider's clinical judgment and the program's protocols. Contact the program directly to confirm switching policies and any associated costs before enrolling.
