The short answer

Switching from AltRx to PlexusDx requires coordination but is straightforward: complete PlexusDx's 60-second intake, receive provider approval and a new prescription, then time your final AltRx dose so the PlexusDx shipment arrives before you run out. AltRx advertised promotional pricing—$89/month for semaglutide and $149/month for tirzepatide—that ended September 5, 2026; standard ongoing rates were not captured. PlexusDx month-to-month semaglutide costs $189, and tirzepatide costs $289, substantially higher than AltRx's promotional figures but with transparent published pricing and a documented 4.3-star Trustpilot rating with 83% of reviews at four stars or higher (captured September 9, 2026). One Trustpilot review and one Reddit thread allege that AltRx billed some customers for a full year upfront despite selecting month-to-month plans; these are individual reports on review platforms, not verified through checkout. Neither provider guarantees uninterrupted supply or dose equivalence during a transfer, so confirm your current dose, prescription status, and cancellation terms with AltRx directly before initiating the switch.

At-a-glance: AltRx vs PlexusDx

All figures captured September 4–7, 2026. AltRx promotional pricing ended September 5, 2026; standard ongoing rates were not documented. PlexusDx pricing is standard, published, and current as of September 7, 2026.

Like-for-like pricing: AltRx vs PlexusDx over 12 months

AltRx advertised promotional rates that expired September 5, 2026. Because standard post-promotion rates were not captured, this comparison uses the promotional figures with explicit labeling. PlexusDx costs more on a month-to-month basis, but pricing is transparent and published without promotional windows.

Semaglutide injection

Month-to-month: AltRx advertised $89/month during its promotional period (ended September 5, 2026), which would total $1,068 over 12 months (our calculation). PlexusDx month-to-month is $189/month, totaling $2,268 over 12 months—$100 more per month or $1,200 more annually than AltRx's promotional rate.

6-month prepaid: AltRx advertised $480 upfront per six-month period during promotion (averaging $80/month, our calculation), totaling $960 over 12 months. PlexusDx 6-month plan is $894 per six-month period ($149/month), totaling $1,788 over 12 months—$69 more per month or $828 more annually than AltRx's promotional prepaid rate.

Tirzepatide injection

Month-to-month: AltRx advertised $149/month during promotion (ended September 5, 2026), totaling $1,788 over 12 months (our calculation). PlexusDx month-to-month is $289/month, totaling $3,468 over 12 months—$140 more per month or $1,680 more annually than AltRx's promotional rate.

6-month prepaid: AltRx advertised $780 upfront per six-month period during promotion (averaging $130/month, our calculation), totaling $1,560 over 12 months. PlexusDx 6-month plan is $1,494 per six-month period ($249/month), totaling $2,988 over 12 months—$119 more per month or $1,428 more annually than AltRx's promotional prepaid rate.

AltRx figures reflect promotional pricing that ended September 5, 2026; standard ongoing rates were not captured. 12-month totals are our calculation. PlexusDx pricing is standard, published, and current as of September 7, 2026.

Step-by-step: switching from AltRx to PlexusDx without a supply gap

Neither provider guarantees uninterrupted supply or dose equivalence during a transfer. The following steps minimize—but cannot eliminate—the risk of a gap between your final AltRx dose and your first PlexusDx shipment.

1. Confirm your current dose and supply

Check your AltRx account or prescription label for your current medication (semaglutide or tirzepatide), dose strength, and injection frequency. Note the date of your last dose and calculate how many doses remain in your current vial. Most patients inject once weekly, so a 28-day supply typically covers four doses.

2. Complete the PlexusDx intake and receive provider approval

Visit the PlexusDx intake page and answer questions about your health history, current medications, and weight-management goals. A licensed provider reviews your intake—typically within one business day—and confirms whether you're a candidate for semaglutide or tirzepatide. The provider writes a new prescription; PlexusDx does not transfer existing prescriptions from other providers.

3. Time your PlexusDx order to arrive before you run out

After provider approval, PlexusDx ships medication from a licensed 503A compounding pharmacy. Standard shipping typically takes 3–7 business days, though PlexusDx does not guarantee delivery timelines. If you have two weeks of AltRx supply remaining, initiate your PlexusDx intake immediately. If you have less than one week remaining, contact PlexusDx support to confirm the earliest possible ship date and consider requesting expedited shipping if available.

4. Cancel your AltRx subscription

AltRx advertises "cancel anytime," but one Trustpilot review (captured September 4, 2026) and one Reddit thread allege that some customers were billed for a full year upfront despite selecting month-to-month plans. These are individual reports on review platforms, not verified facts. Before canceling, confirm your billing cycle, any outstanding charges, and the cancellation process directly with AltRx support. Request written confirmation of your cancellation and final bill. Do not cancel AltRx until your PlexusDx shipment is in hand if you are on your final AltRx dose.

5. Discuss dose matching with your PlexusDx provider

If you've been stable on a specific dose with AltRx, note that dose in your PlexusDx intake. The PlexusDx provider may match your current dose, adjust it based on clinical judgment, or restart titration from a lower dose depending on how long you've been on GLP-1 therapy and your response. Neither provider guarantees dose continuity during a transfer. If maintaining your exact dose is critical, discuss this explicitly with your PlexusDx provider during the intake review or via support before finalizing your order.

Decision factors: when switching makes sense

Price transparency and review record

AltRx's promotional pricing ended September 5, 2026, and standard ongoing rates were not captured in this research. PlexusDx publishes standard rates with no promotional windows: $189/month month-to-month for semaglutide and $289/month for tirzepatide. 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). If predictable monthly costs and a documented review record are priorities, PlexusDx offers both despite the higher price.

Billing practices and cancellation clarity

One Trustpilot review and one Reddit thread allege that AltRx billed some customers for a full year upfront despite their selecting month-to-month plans. These are individual reports, not verified through checkout. AltRx advertises "cancel anytime" and offers 1-month, 3-month, 6-month, and 12-month plan options, with longer prepaid tiers priced lower. If you're uncertain about your AltRx billing terms or concerned about prepayment, confirm your exact plan and cancellation rights with AltRx support before switching. PlexusDx month-to-month plans bill monthly; multi-month plans charge the full period upfront (e.g., $507 for a 3-month semaglutide plan).

Medication options

Both AltRx and PlexusDx offer compounded semaglutide and tirzepatide injections. PlexusDx also offers oral semaglutide capsules ($289/month month-to-month) and oral tirzepatide capsules ($349/month month-to-month) for patients who prefer not to inject, plus a microdose GLP-1 protocol ($129/month) for maintenance after initial weight loss. If you're interested in transitioning from injections to oral capsules or exploring maintenance dosing, PlexusDx provides those pathways within one provider relationship.

Choose AltRx if…

You secured AltRx's promotional pricing before September 5, 2026, confirmed your exact billing terms and cancellation rights in writing, and your monthly cost remains substantially lower than PlexusDx's published rates. AltRx advertised $89/month for semaglutide and $149/month for tirzepatide during its promotional window—both well below PlexusDx's $189 and $289 month-to-month rates—so if you locked in those figures and verified they apply beyond the promotional period, the price advantage is significant. Confirm your ongoing rate, billing cycle, and cancellation terms directly with AltRx support to avoid surprises.

Choose PlexusDx if…

You want published, non-promotional pricing with a documented review record, especially if you're switching after AltRx's promotional period ended or if you're uncertain about your AltRx billing terms. PlexusDx's $189/month semaglutide and $289/month tirzepatide rates are substantially higher than AltRx's advertised promotional figures, but PlexusDx publishes standard rates with no expiration dates, holds a 4.3-star Trustpilot rating with 83% of reviews at four stars or higher, and offers oral capsule and microdose maintenance options if you want to transition away from injections later. Month-to-month plans bill monthly; multi-month plans reduce the per-month rate and charge upfront for the full period. If transparent pricing, a documented service record, and expanded medication options outweigh the higher monthly cost, PlexusDx is the clearer long-term choice.

Methodology and freshness

AltRx pricing, plan structure, and promotional expiration date were captured September 4, 2026, from the AltRx website. The promotional period ended September 5, 2026; standard post-promotion rates were not documented. The Trustpilot billing allegation and Reddit thread were captured September 4, 2026. PlexusDx pricing was captured September 7, 2026, from published product pages. The PlexusDx Trustpilot rating (4.3 stars, 79% five-star, 83% four-star or higher) was captured September 9, 2026. All 12-month cost calculations are ours, derived from the captured per-month or prepaid figures. Neither provider guarantees uninterrupted supply, dose equivalence, or specific transfer timelines; the switching steps reflect general telehealth prescription workflows but are not verified through direct transfer coordination. Readers should confirm current pricing, billing terms, cancellation policies, and transfer procedures directly with both providers before initiating a switch.

Frequently Asked Questions

Can I transfer my AltRx prescription directly to PlexusDx?

No. PlexusDx does not transfer prescriptions written by other providers. You complete a new intake, and a PlexusDx-affiliated licensed provider reviews your information and writes a new prescription if you're approved. Your AltRx prescription remains with AltRx and cannot be moved between telehealth platforms.

Will my dose stay the same when I switch from AltRx to PlexusDx?

Not necessarily. The PlexusDx provider may match your current dose, adjust it based on clinical judgment, or restart titration from a lower dose depending on your treatment history and response. Note your current dose in the PlexusDx intake and discuss dose continuity with your provider if maintaining your exact dose is important to you.

How long does PlexusDx take to ship medication after provider approval?

Standard shipping from PlexusDx's licensed 503A compounding pharmacy typically takes 3–7 business days after provider approval, though PlexusDx does not guarantee specific delivery timelines. If you're running low on AltRx supply, initiate your PlexusDx intake at least two weeks before your final dose and contact PlexusDx support to confirm the earliest possible ship date.

Did AltRx really bill customers for a full year despite offering month-to-month plans?

One Trustpilot review and one Reddit thread allege that AltRx charged some customers for a full year upfront even when they selected month-to-month billing. These are individual reports on review platforms, not verified facts. AltRx advertises "cancel anytime" and offers 1-month, 3-month, 6-month, and 12-month plan options. Confirm your exact billing terms, plan length, and cancellation rights in writing with AltRx support before committing to or canceling a subscription.

What happens if my PlexusDx shipment arrives late and I miss a dose?

Neither AltRx nor PlexusDx guarantees delivery timelines or uninterrupted supply during a provider switch. If you miss a weekly injection, the general clinical guidance is to take your dose as soon as you remember if it's within five days of the scheduled day, then resume your regular schedule. If more than five days have passed, skip the missed dose and take your next dose on the regular day. Contact your PlexusDx provider for specific guidance if a supply gap occurs.
