Visit InstaRXThe verdict for women
CoreAge Rx edges out InstaRX on the Metabolic-Fit Score, 92 to 45 (A− vs C). Mothers who want a fixed monthly price, a real clinician rather than an intake quiz, and uninterrupted nationwide access to both semaglutide and tirzepatide while they work out the timing around pregnancy or weaning.
InstaRX is still a genuine option — a flat-price compounded shop — $179/mo semaglutide, $259/mo tirzepatide, same price at any dose — though the site doesn't itemize what's actually bundled into that number. Weigh the six women's-health factors below against your own priorities.

Metabolic-Fit / 100
CoreAge Rx
Ranked #1 · Grade A−
What we like
- A single flat monthly rate — no teaser first month that jumps at the first refill
- A prescriber reviews your history and will actually talk through timing if you're postpartum, nursing, or planning another pregnancy
- Semaglutide and tirzepatide on one chart, so switching molecules doesn't mean switching providers
The caveats
- Not the lowest sticker price — a couple of budget compounders come in under it
- Compounded only; there's no FDA-approved brand Wegovy or Zepbound lane here
- A general metabolic program, not a dedicated OB or hormone practice
Metabolic-Fit / 100
InstaRX
Ranked #39 · Grade C
What we like
- Both molecules' flat prices visible directly on the treatments page, no intake required
- Same price at any dose — no escalation surcharge as titration increases
- 680+ reviews at an 'Excellent' rating claimed on-site
The caveats
- The homepage doesn't itemize what's bundled into the flat price (consult, shipping, supplies)
- No brand-name (FDA-approved) option and no oral form
- No mention anywhere of pregnancy, breastfeeding, postpartum care, or PCOS
