The short answer

SlimDownRx offers compounded tirzepatide injections in prepaid 3-, 6-, and 9-month bundles—no semaglutide product has been documented in any verified source. Available pricing ranges from $850 to $2,825 upfront depending on dose and duration, translating to monthly prepaid equivalents of $258.33 to $341.67. All pricing data is secondary-source only (captured from a Reddit post on September 4, 2026), not verified through direct checkout. No month-to-month option, no documented renewal structure, and no information on refunds or cancellation terms exists in available evidence. PlexusDx offers both semaglutide and tirzepatide in month-to-month and commitment plans at flat rates regardless of dose, with tirzepatide starting at $289/month month-to-month or $249/month on a 6-month commitment.

What SlimDownRx offers: tirzepatide only

According to available evidence captured September 4, 2026, SlimDownRx sells compounded tirzepatide injections exclusively. No semaglutide product—injection or oral—has been documented in any verified source. The pricing structure is prepaid multi-month bundles with dose-specific rates: 10 mg, 12.5 mg, and 15 mg tiers. No membership fee is mentioned in the available data, but the evidence base is limited to a single secondary source (a Reddit post in r/tirzepatidecompound) and carries a research flag noting "Primary checkout verification required" and "Primary site not indexed."

All figures below are from secondary-source evidence captured September 4, 2026, 13:49:55 UTC, and require full prepayment for the stated period. Monthly equivalents are our calculation.

Evidence status: All SlimDownRx pricing is sourced from a Reddit post (r/tirzepatidecompound, posted date not captured) and has not been verified through direct checkout observation. The research dataset explicitly flags "Primary checkout verification required" and notes "Primary site not indexed." Confirm all figures, terms, and product availability at checkout before committing funds.

PlexusDx tirzepatide and semaglutide pricing

PlexusDx offers both compounded semaglutide and tirzepatide injections in month-to-month and commitment plans. Pricing is the same at every dose within each medication class.

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).

12-month cost comparison: tirzepatide injection

Because SlimDownRx offers no semaglutide product, a like-for-like comparison is only possible for tirzepatide. The calculations below assume repeating the prepaid bundle as needed to reach 12 months; all prepaid figures and monthly equivalents are our calculation.

Key finding: PlexusDx 6-month tirzepatide ($2,988 over 12 months) is $112 less expensive than SlimDownRx's lowest documented prepaid 10 mg option ($3,100 over 12 months). However, comparing PlexusDx month-to-month ($3,468) to SlimDownRx 6-month prepaid 10 mg ($3,100) shows SlimDownRx $368 less expensive when trading maximum flexibility for a 6-month upfront commitment. SlimDownRx pricing varies by dose; higher doses (12.5 mg, 15 mg) substantially increase cost. All SlimDownRx figures assume your clinician prescribes and maintains the stated dose for the full prepaid period.

Decision factors: evidence quality and flexibility

Evidence limitations: All SlimDownRx pricing is secondary-source only, captured from a Reddit community post rather than direct checkout verification. The research dataset flags "Primary checkout verification required" and "Primary site not indexed," meaning the figures above may not reflect current checkout reality, available doses, plan options, or terms. No information on cancellation policy, refunds, dose-change procedures, or customer support channels exists in available evidence.

Medication availability: SlimDownRx documentation shows tirzepatide only; if you need semaglutide, SlimDownRx is not an option per available evidence. PlexusDx offers both semaglutide and tirzepatide in injection and oral forms, plus a microdose maintenance protocol.

Prepayment vs. month-to-month: SlimDownRx requires full prepayment for 3, 6, or 9 months with no documented month-to-month alternative. PlexusDx offers month-to-month plans with no upfront commitment alongside optional commitment discounts. If your dose changes, you experience intolerable side effects, or you need to pause treatment, the prepaid model offers no documented flexibility.

Dose-based pricing: SlimDownRx charges different rates for 10 mg, 12.5 mg, and 15 mg doses. If your clinician titrates you to a higher maintenance dose, your monthly cost increases. PlexusDx charges the same rate at every dose within each medication class, eliminating cost uncertainty as your treatment progresses.

Choose SlimDownRx if…

• You need tirzepatide specifically (not semaglutide) and can confirm current product availability and checkout terms directly with SlimDownRx.
• Your clinician has prescribed a stable 10 mg tirzepatide dose and you are comfortable prepaying $1,550 for six months ($258.33/month prepaid equivalent) or $2,325 for nine months ($258.33/month prepaid equivalent).
• You accept the evidence limitations: all available pricing is secondary-source, not checkout-verified, and no cancellation or refund terms are documented.
• You do not require month-to-month flexibility or the option to pause without forfeiting prepaid funds.

Choose PlexusDx if…

• You need semaglutide (SlimDownRx offers no semaglutide product per available evidence) or want the option to switch between semaglutide and tirzepatide as your treatment evolves.
• You value month-to-month flexibility with no upfront commitment: PlexusDx tirzepatide is $289/month month-to-month, and you can pause or cancel without forfeiting prepaid funds.
• You want cost certainty across dose changes: PlexusDx charges $249/month (6-month commitment) or $289/month (month-to-month) at every tirzepatide dose, so titration never increases your monthly cost.
• You prefer checkout-verified pricing, transparent terms, and a documented review record (4.3 stars on Trustpilot, 83% four stars or higher, captured September 9, 2026).
• You want the lowest documented 12-month tirzepatide cost with commitment flexibility: PlexusDx 6-month commitment totals $2,988 over 12 months, $112 less than SlimDownRx's lowest documented prepaid option.
