Head-to-head comparison
CoreAge Rx vs Prime Doctor RX
Two GLP-1 providers, one scorecard. Both are graded on the same six Desk Score dimensions — here is how they stack up, and which one fits you.
Desk Score
One price at every dose, both molecules, all 50 states. The $99 and $149 figures are 12-month plans paid up front, not a monthly bill.
$99/mo (12-month prepay) sema · $149/mo (12-month prepay) tirz · Verified August 2026
Marked down on: The advertised $99/$149 per month is a 12-month plan paid in full ($1,188 / $1,788 up front); no month-to-month price is published
Desk Score
The whole ladder is public and the asterisk is honest — but the billing cycle is 28 days and every price is labeled per month anyway.
$249 per 4 weeks sema · $339 per 4 weeks tirz · Verified September 2026
Marked down on: 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.
CoreAge Rx takes this head-to-head with the higher Desk Score, 94/100 (A) against 70/100 (C) for Prime Doctor RX. Prime Doctor RX still holds its ground where its strengths line up with yours.
