The short answer

Fifty410 undercuts PlexusDx on tirzepatide by bundling three months at a time and charging upfront—its starter tier costs $1,872 less over 12 months than PlexusDx's month-to-month tirzepatide plan. For semaglutide billed monthly, PlexusDx costs $10 less per month ($120 over 12 months). Both providers ship compounded injectable GLP-1 drugs; neither charges membership fees; Fifty410 offers no monthly option for tirzepatide, and its pricing page and help center show conflicting legacy rates, so confirm final figures at checkout.

Normalized 12-month cost comparison

Semaglutide injection, month-to-month

Calculation (our calculation): $189 × 12 = $2,268 (PlexusDx); $199 × 12 = $2,388 (Fifty410).

Difference: PlexusDx costs $120 less over 12 months, or $10 less per month. Both plans bill monthly with no upfront commitment; both include provider consult, medication, and shipping; neither charges a membership fee.

Tirzepatide injection: month-to-month vs three-month prepaid

Fifty410 does not offer a month-to-month tirzepatide option. Its tirzepatide plans require three-month prepayment and ship the full supply upfront. The table below compares PlexusDx's month-to-month tirzepatide rate against Fifty410's prepaid tiers over 12 months (four consecutive three-month cycles).

Calculation (our calculation): PlexusDx $289 × 12 = $3,468. Fifty410 Starter $399 × 4 cycles = $1,596; Mid $499 × 4 = $1,996; High $549 × 4 = $2,196.

Difference: Fifty410's starter tier costs $1,872 less over 12 months than PlexusDx's month-to-month plan. Fifty410 Mid is $1,472 less; High is $1,272 less. The trade-off: Fifty410 requires $399–$549 upfront every three months; PlexusDx bills $289 monthly with no prepayment.

Tirzepatide: like-for-like three-month prepaid comparison

PlexusDx offers a three-month prepaid tirzepatide plan at $269 per month ($807 per cycle). The table below compares this prepaid option against Fifty410's three-month tiers over 12 months.

Calculation (our calculation): PlexusDx $807 × 4 = $3,228. Fifty410 Starter $399 × 4 = $1,596; Mid $499 × 4 = $1,996; High $549 × 4 = $2,196.

Difference: Even when comparing prepaid plans, Fifty410's starter tier is $1,632 less over 12 months than PlexusDx's three-month prepaid option. Fifty410 Mid is $1,232 less; High is $1,032 less.

Decision factors

Medication and routes

Both providers ship compounded semaglutide and tirzepatide injections. PlexusDx also offers oral semaglutide capsules ($289/month month-to-month, $269/month three-month prepaid, $249/month six-month prepaid), oral tirzepatide capsules ($349/month month-to-month, $299/month three-month prepaid, $279/month six-month prepaid), and a microdose GLP-1 injection protocol ($129/month). Fifty410's product catalog is limited to injectable compounded semaglutide and tirzepatide; no oral or microdose options were documented in the captured evidence (Fifty410 pricing page and help center, accessed September 4, 2026).

Billing structure and upfront commitment

PlexusDx bills semaglutide and tirzepatide month-to-month by default; multi-month prepaid plans (three-month and six-month) are optional and reduce the per-month rate. Fifty410 bills semaglutide monthly ($199/month) but requires three-month prepayment for tirzepatide—you pay $399, $499, or $549 upfront depending on dose tier, and the full three-month supply ships immediately. There is no monthly tirzepatide option at Fifty410. If monthly billing and lower upfront cash outlay matter more than the lowest absolute cost, PlexusDx's tirzepatide month-to-month plan ($289/month) offers that flexibility; if you can prepay and want the lowest 12-month total, Fifty410's tirzepatide starter tier delivers a $1,872 annual saving versus PlexusDx's month-to-month rate.

Dose pricing

PlexusDx charges the same monthly rate regardless of dose—starting dose, maintenance dose, and maximum dose all cost $189/month for semaglutide injection or $289/month for tirzepatide injection (month-to-month plans). Fifty410 uses tiered pricing for tirzepatide: starter-dose patients pay $399 per three-month cycle, mid-dose patients pay $499, and high-dose patients pay $549. For semaglutide, Fifty410 charges a flat $199/month at every dose. This means your Fifty410 tirzepatide cost will climb as your provider titrates you upward; PlexusDx's cost remains constant.

Review ratings and volume

Fifty410 holds a 4.8-star rating across 5,891 reviews on Trustpilot (provider page claim, captured September 4, 2026). 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). Both ratings reflect overall satisfaction in the high-4-star range; Fifty410's larger review volume and higher average suggest consistently positive patient experience, though individual results and service quality can vary.

Pricing discrepancies and transparency

Fifty410's primary pricing page (accessed September 4, 2026) shows $199/month for semaglutide and three tirzepatide tiers at $399/$499/$549 per three-month cycle. However, older help-center articles captured the same day reference different rates, indicating legacy pricing that has not been updated. When comparing or enrolling, confirm the final price at checkout and verify whether the rate you see applies to refills or only the first cycle.
