The short answer

PlexusDx charges $189/month for semaglutide injection and $289/month for tirzepatide injection, both billed monthly with no prepayment. Fifty410 charges $199/month for semaglutide (billed monthly) and requires $399–$549 upfront for each three-month supply of tirzepatide, depending on dose tier. The choice turns on whether you want the flexibility of month-to-month billing at every dose or the lower per-month tirzepatide cost that comes with committing $399–$549 every three months.

Semaglutide: month-to-month comparison

Both providers offer compounded semaglutide injection on a monthly billing cycle. PlexusDx charges $189 per month; Fifty410 charges $199 per month. Neither requires prepayment or a multi-month commitment for semaglutide, and both charge the same price regardless of dose.

Over 12 months, PlexusDx semaglutide costs $2,268 (our calculation: $189 × 12); Fifty410 semaglutide costs $2,388 (our calculation: $199 × 12). Fifty410 costs $120 more per year, or $10 per month.

Tirzepatide: monthly billing vs three-month prepay

The tirzepatide comparison requires understanding two different billing structures. PlexusDx charges $289 per month billed monthly at every dose. Fifty410 ships tirzepatide as a three-month supply requiring $399, $499, or $549 upfront depending on dose tier (starter, mid, or high dose), then repeats that upfront charge every three months.

Fifty410's tirzepatide per-month equivalents (our calculation, prepaid):

• Starter dose: $399 upfront per 3-month supply = $133/month equivalent (prepaid)
• Mid dose: $499 upfront per 3-month supply = $166/month equivalent (prepaid)
• High dose: $549 upfront per 3-month supply = $183/month equivalent (prepaid)

Over 12 months, Fifty410's tirzepatide costs $1,596 (starter, our calculation: $399 × 4), $1,996 (mid, our calculation: $499 × 4), or $2,196 (high, our calculation: $549 × 4). PlexusDx month-to-month tirzepatide costs $3,468 over 12 months (our calculation: $289 × 12). Even at the highest dose tier, Fifty410's prepaid plan costs $1,272 less per year than PlexusDx month-to-month tirzepatide.

The trade-off: Fifty410's lower annual cost requires $399–$549 upfront every three months, and the per-month cost rises as your dose increases. PlexusDx bills the same $289 rate monthly at every dose with no prepayment.

Decision factors

Cash flow and commitment

PlexusDx bills $189 or $289 each month with no prepayment. You can pause or cancel before the next monthly charge. Fifty410 semaglutide works the same way at $199/month. Fifty410 tirzepatide requires $399–$549 upfront for a three-month supply, then repeats that charge every three months. If you want to stop, you've already paid for the remainder of the current three-month period.

Dose escalation and pricing predictability

PlexusDx charges the same rate at every dose: $189/month for semaglutide and $289/month for tirzepatide regardless of whether you're on a starter dose or the maximum. Fifty410 charges one rate for semaglutide ($199/month at all doses) but three tirzepatide tiers: starter ($133/month equivalent prepaid), mid ($166/month equivalent prepaid), and high ($183/month equivalent prepaid). If you escalate from starter to mid dose at Fifty410, your upfront charge rises from $399 to $499 every three months.

Annual cost at stable doses

If you expect to stay on a stable tirzepatide dose for the full year and can commit the upfront cash every three months, Fifty410's prepaid structure saves between $1,272 and $1,672 annually compared to PlexusDx month-to-month (depending on dose tier). For semaglutide, PlexusDx costs $120 less per year than Fifty410 on the month-to-month comparison.

Choose Fifty410 if…

• You're starting tirzepatide, can commit $399–$549 upfront every three months, and want the lowest per-month equivalent cost.
• Your dose is stable and you're comfortable prepaying for three months at a time.
• Lower annual spending on tirzepatide outweighs the inconvenience of quarterly lump-sum payments.

Choose PlexusDx if…

• You want true month-to-month billing with no prepayment for semaglutide or tirzepatide.
• You prefer one flat rate at every dose without tier-based pricing as you escalate.
• You're choosing semaglutide and want the lower monthly cost ($189 vs $199).
• You value the flexibility to pause or adjust after each monthly charge rather than committing cash for three months at once.
