The short answer

Amble and PlexusDx both offer flat monthly pricing for compounded GLP-1 injections with no membership fees, no hidden costs, and month-to-month billing. Amble prices compounded semaglutide with a first-month advertised rate of $179 and ongoing refills at $199/month, and compounded tirzepatide in two tiers: $289/month for starter doses (2.5–5 mg) and $329/month for higher doses (7.5–15 mg). PlexusDx prices compounded semaglutide at $189/month and compounded tirzepatide at a single flat rate of $289/month regardless of dose. Over 12 months, Amble's semaglutide costs $2,398 ($179 first month + eleven refills at $199) versus PlexusDx's $2,268—a $130 difference favoring PlexusDx. Low-dose tirzepatide costs $3,468 at both providers. High-dose tirzepatide costs $3,948 at Amble versus $3,468 at PlexusDx—a $480 advantage for PlexusDx. PlexusDx also offers 3-month and 6-month commitment pricing that lowers per-month rates further, and provides oral formulations and a microdose maintenance option not available at Amble. The better choice depends on whether you prioritize the lowest semaglutide cost or flat tirzepatide pricing as you titrate.

At-a-glance comparison

Evidence note: Amble pricing was captured from the provider's published FAQ (hosted on Canva) on September 4, 2026. The figures represent Amble's own advertised rates but were not validated at checkout. PlexusDx pricing reflects standard published rates as of September 10, 2026, with month-to-month rates confirmed in July 2026 site captures.

Like-for-like monthly pricing breakdown

Both Amble and PlexusDx use month-to-month billing with no prepay requirement at the baseline tier. Amble advertises a first-month rate for semaglutide with a higher ongoing refill rate; PlexusDx maintains a single flat rate throughout treatment.

Compounded semaglutide injection

• Amble: $179 first month, $199/month ongoing refill rate at all doses
• PlexusDx: $189/month at all doses (month-to-month); $169/month on 3-month commitment; $149/month on 6-month commitment
• 12-month cost (MTM): Amble $2,398 ($179 + 11 × $199); PlexusDx $2,268 (our calculation)
• Difference: PlexusDx is $130 lower over 12 months

Amble's first-month advertised rate of $179 is $10 lower than PlexusDx's flat $189, but the ongoing $199 refill rate means PlexusDx's single flat rate saves $130 over a full year. PlexusDx's 6-month commitment rate ($149/month, or $1,788 over 12 months prepaid per-month calculation—our calculation) offers further savings, but that comparison crosses billing-model boundaries: Amble does not publish a multi-month prepaid option in the available evidence.

Compounded tirzepatide injection: low-dose tier

• Amble: $289/month for 2.5–5 mg doses
• PlexusDx: $289/month at all doses (month-to-month); $269/month on 3-month commitment; $249/month on 6-month commitment
• 12-month cost (MTM): Both $3,468 (our calculation)
• Difference: Equal at month-to-month baseline

At starter tirzepatide doses, Amble and PlexusDx charge identical month-to-month rates. PlexusDx's commitment pricing ($269 or $249/month) again offers a lower effective rate for patients willing to prepay.

Compounded tirzepatide injection: high-dose tier

• Amble: $329/month for 7.5–15 mg doses
• PlexusDx: $289/month at all doses (month-to-month)
• 12-month cost (MTM): Amble $3,948; PlexusDx $3,468 (our calculation)
• Difference: PlexusDx is $480 lower over 12 months, or $40/month

Amble's two-tier tirzepatide pricing creates a $40/month gap at higher doses. PlexusDx maintains a single flat rate regardless of titration, which produces a clear advantage for patients on maintenance doses above 5 mg.

Decision factors beyond the per-month rate

Dose-tier structure and titration

Amble's two-tier tirzepatide model mirrors cost structure at some other compounded providers: lower monthly cost during titration, higher cost at maintenance. PlexusDx's single flat rate simplifies budgeting and eliminates a price jump mid-treatment. For semaglutide, both providers charge one flat rate at all doses.

Commitment discounts and prepay options

PlexusDx offers 3-month and 6-month commitment pricing that lowers the effective monthly rate: semaglutide drops to $149/month on a 6-month plan, and tirzepatide to $249/month. Amble's pricing in the captured evidence is month-to-month only; no multi-month prepay figures were published. Patients who prefer to lock in a lower rate and are confident in multi-month adherence may favor PlexusDx's commitment tiers; those who want maximum month-to-month flexibility will appreciate Amble's baseline semaglutide rate.

Medication variety

Amble advertises compounded semaglutide and tirzepatide injections only. PlexusDx offers the same two injections plus oral semaglutide capsules ($289/month month-to-month), oral tirzepatide capsules ($349/month month-to-month), and a microdose GLP-1 maintenance protocol ($129/month). Patients interested in needle-free administration or a lower-cost maintenance option have those choices at PlexusDx; they are not advertised at Amble in the available evidence.

Review record and service transparency

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). Amble's Trustpilot and Reddit presence was indexed in the research but rating, volume, and thematic review data were not captured, so a side-by-side service-quality comparison is not supported by the available evidence.

Choose Amble if…

• You are starting tirzepatide and expect to remain at or below 5 mg, where Amble matches PlexusDx at $289/month.
• You strongly prefer true month-to-month billing with no multi-month commitment decision to evaluate.

Choose PlexusDx if…

• You want compounded semaglutide injection and prefer a lower total annual cost—PlexusDx saves $130 over 12 months versus Amble's first-month-plus-refill pricing.
• You are on or plan to titrate to higher tirzepatide doses (7.5 mg or above), where PlexusDx's flat $289/month saves $40/month versus Amble's $329 high-dose tier.
• You want access to oral semaglutide, oral tirzepatide, or a microdose GLP-1 maintenance protocol not advertised at Amble.
• You are willing to commit to 3 or 6 months to capture lower effective monthly rates ($149/month semaglutide or $249/month tirzepatide on the 6-month plan).
• You value a documented Trustpilot review record (4.3 stars, 83% four-star or higher) as part of your provider-selection research.

Frequently Asked Questions

Does Amble charge a membership fee or hidden costs?

No. Amble advertises $0 membership fee and no hidden or shipping fees. The published per-month medication rate ($179 first month then $199 ongoing for semaglutide; $289 or $329 tirzepatide) is described as all-inclusive with monthly billing and no prepay requirement.

Why does Amble price tirzepatide in two tiers?

Amble charges $289/month for tirzepatide doses between 2.5 mg and 5 mg, and $329/month for doses between 7.5 mg and 15 mg. This two-tier model reflects different compound concentrations or vial sizes. PlexusDx uses a single flat rate ($289/month month-to-month) at every tirzepatide dose, which eliminates a mid-treatment price increase.

Can I switch from month-to-month to a commitment plan at PlexusDx?

PlexusDx offers month-to-month, 3-month, and 6-month billing options. Policy on mid-cycle plan changes is not detailed in the captured sources; contact PlexusDx support to confirm whether you can move from monthly to a commitment tier or vice versa after your initial order.

Does either provider offer brand-name Wegovy or Zepbound?

No. Both Amble and PlexusDx dispense compounded semaglutide and tirzepatide, which are not FDA-approved and differ from brand-name Wegovy, Ozempic, Mounjaro, or Zepbound. A licensed clinician determines whether a compounded prescription is appropriate for you.

How do I confirm Amble's pricing at checkout?

The pricing in this comparison was captured from Amble's published FAQ on September 4, 2026, and represents the provider's advertised rates. Because the figures were not validated during a live checkout session, you should complete Amble's intake process and review the final order summary before payment to confirm the current rate, dose tier, and any terms or conditions.
