WeightRx vs Prime Doctor RX
Two GLP-1 programs on the bench, scored on the same six factors. Here's how their real cost of ownership compares — and which one we'd start with.
WeightRx
Cost-first shoppers who want the lowest published tirzepatide figure, if you are willing to complete intake before you can read the plan terms.

Someone who will convert every figure into four-week cycles before comparing it with anything else here.
Visit Prime Doctor RXThe verdict
WeightRx and Prime Doctor RX tie on the Cost-Efficiency Index at 69/100, so neither wins outright on the numbers. For most shoppers we'd start with WeightRx (ranked #109, a hair above #110) — Cost-first shoppers who want the lowest published tirzepatide figure, if you are willing to complete intake before you can read the plan terms. But Prime Doctor RX is a genuine coin-flip alternative here.
Worth knowing either way: our overall #1 pick is CoreAge Rx (Cost-Efficiency Index 94/100 — the top of the ranking). See how it stacks up: CoreAge Rx vs WeightRx.

WeightRx
69/100Where the value is
- The tirzepatide figure is published up front, and it is genuinely low against the field
- Both molecules are offered
- No membership charge is advertised alongside the medication rate
The tradeoffs
- The $83 monthly rate is advertised as '$83/month ($997/year)', which is twelve months of it — no month-to-month rate is separately published, and the terms state that a rate is locked for its full term
- Both product pages linked from the homepage return 404, so the plan terms cannot be read before intake
Prime Doctor RX
69/100Where the value is
- The full ladder for all three weight-loss products and for TRT sits on the homepage before any intake
- Every card's footnote says the starting price is the 52-week prepay, in full
- The four-week shipping cycle is disclosed in that same footnote rather than left to a bank statement
The tradeoffs
- Its own arithmetic proves the 28-day cycle — $3,497 divided by thirteen is exactly $269, and nothing on the page divides cleanly by calendar months
- A year of month-to-month tirzepatide therefore costs $4,407 rather than the $4,068 per-month pricing implies
