The short answer

Amble and PlexusDx both offer compounded semaglutide and tirzepatide injections on month-to-month billing with no separate membership fees. For semaglutide, Amble's introductory rate is $179/month, while PlexusDx charges $189/month month-to-month. For tirzepatide, both charge $289/month at the low-dose tier, but Amble adds a $329/month rate for higher doses (7.5–15 mg) while PlexusDx holds the same $289 price at every dose—a $40/month advantage at maintenance levels. PlexusDx also offers three-month and six-month prepaid tiers that reduce the effective monthly rate to $149 for semaglutide and $249 for tirzepatide, and extends the product line to oral semaglutide, oral tirzepatide, and microdose maintenance options that Amble does not carry. If you want the lowest advertised semaglutide price and plan to stay on a starter dose, Amble's first-month rate is lower. If you expect to titrate to higher tirzepatide doses or value prepaid discounts and product variety, PlexusDx offers a lower long-term cost and broader choice.

At-a-glance plan comparison

Amble pricing captured September 4, 2026 from public FAQ. PlexusDx pricing current as of September 20, 2026. Prepaid rates are our calculation of the effective monthly cost when paying upfront for three or six months.

Like-for-like pricing and 12-month cost

Both programs bill month-to-month with no long-term contract, so the most direct comparison uses the monthly subscription rate and multiplies by twelve. Where PlexusDx offers prepaid multi-month tiers, we show the effective monthly rate and the upfront commitment required.

Compounded semaglutide injection

Amble's first-month rate: $179/month is advertised; confirm whether refills continue at the same price or adjust upward. If the $179 rate holds, Amble is $10/month ($120/year) less than PlexusDx month-to-month. PlexusDx's advantage: The six-month tier saves $30/month ($360/year) compared to Amble's advertised first-month rate (assuming that rate continues), but requires $894 upfront every six months.

Compounded tirzepatide injection—low dose (2.5–5 mg)

Identical month-to-month pricing. PlexusDx's six-month tier saves $40/month ($480/year) compared to both providers' MTM rates, requiring $1,494 upfront every six months.

Compounded tirzepatide injection—high dose (7.5–15 mg)

PlexusDx's advantage: $40/month ($480/year) less than Amble at the high-dose tier because PlexusDx holds the same $289 monthly rate at every dose. The six-month tier extends the savings to $80/month ($960/year) compared to Amble's $329 high-dose rate.

Product scope and formulation options

Amble offers compounded semaglutide and tirzepatide injections only. PlexusDx offers those same two injectables plus oral semaglutide capsules ($289/$269/$249 MTM/3-mo/6-mo), oral tirzepatide capsules ($349/$299/$279 MTM/3-mo/6-mo), and a microdose GLP-1 injection protocol at $129/month designed for maintenance after initial weight loss. If you prefer or require a non-injection route, or you want a lower-cost microdose option to sustain results, PlexusDx is the only choice between these two programs.

Commitment, cancellation, and billing flexibility

Both Amble and PlexusDx bill month-to-month by default with no long-term contract. PlexusDx adds optional three-month and six-month prepaid tiers that reduce the per-month rate but require the full commitment paid upfront. Neither program advertises a separate membership fee, and both include shipping in the quoted price. Amble's FAQ (hosted on Canva as of the September 4, 2026 capture) does not document a refund or cancellation policy; confirm the current terms at checkout before committing.

Dose-tier pricing and titration cost

Amble holds semaglutide at an advertised first-month rate of $179/month; confirm whether that rate continues on refills. For tirzepatide, Amble splits pricing into two tiers: $289/month for the 2.5–5 mg starter pack and $329/month once you titrate to 7.5 mg or higher. PlexusDx charges $189/month for semaglutide month-to-month and $289/month for tirzepatide at every dose, month-to-month. That means a patient who titrates from 5 mg to 10 mg on Amble will see a $40/month price increase; the same patient on PlexusDx will see no change. Over a year at maintenance dose, that difference compounds to $480.

Review and service-quality evidence

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 maintains a Trustpilot profile, but rating, volume, and negative-theme data were not captured in the evidence set used for this comparison (as of September 4, 2026). A Reddit discussion thread about Amble's pricing was noted in the research packet, but no specific service complaints or patterns were extracted. We recommend reviewing current Trustpilot and independent community feedback for both providers before committing, particularly for Amble where the public service-quality record is less documented.

Choose Amble if…

• You want the lowest advertised first-month semaglutide price available between these two programs and can confirm that rate holds on refills.
• You are starting tirzepatide and expect to remain at the 2.5–5 mg dose tier, where Amble matches PlexusDx at $289/month.
• You prefer a simple two-product menu (semaglutide injection, tirzepatide injection) with no decision overhead around oral formulations or microdose maintenance.
• You do not require multi-month prepaid discounts or product variety beyond standard compounded injectables.

Choose PlexusDx if…

• You expect to titrate to higher tirzepatide doses (7.5 mg or above) and want to avoid Amble's $40/month upcharge—PlexusDx holds $289/month at every dose.
• You value the option to lock in a lower effective monthly rate through three-month ($169 semaglutide, $269 tirzepatide) or six-month ($149 semaglutide, $249 tirzepatide) prepaid commitments.
• You want access to oral semaglutide or oral tirzepatide capsules as an alternative to injections.
• You are planning for long-term maintenance and want the $129/month microdose GLP-1 protocol as a step-down option after reaching your goal weight.
• You prefer a provider with an established, transparent public review record (4.3-star Trustpilot rating, 83% four stars or higher).

Methodology and freshness

PlexusDx pricing is current as of September 20, 2026 and reflects the standard month-to-month, three-month prepaid, and six-month prepaid tiers published on the PlexusDx product pages. Twelve-month totals and effective monthly rates for prepaid tiers are our calculations (monthly rate × 12 for annual totals; total prepaid commitment ÷ commitment length for effective monthly rates). Review data for PlexusDx was captured from Trustpilot on September 9, 2026. Amble's Trustpilot profile existence was noted on September 4, 2026, but rating and volume were not captured in this research cycle.
