Graded #276 · C
Strengths
- Publishes plan pricing openly, before any intake or account creation
- Month-to-month with no long-term contract and no multi-month prepayment
- Billing starts only after a licensed provider approves treatment
- LegitScript certification verified against the issued seal, not just the badge
Where it loses points
- Its own pricing page contradicts itself: it claims no separate consultation charges, then states a $25-$60 fee applies per visit
- The consultation fee is charged whether or not a prescription is issued
- Advertised $129 and $199 rates are time-limited founding rates; standard rates are $249 and $299
- No compounding pharmacy is named anywhere on the site
- Shipping claims conflict: a 48-hour figure on the homepage against 1-2 days to ship plus 2-3 days transit in the FAQ
Graded #59 · C
Strengths
- Transparent, competitive pricing published up front — compounded semaglutide from $120/mo, tirzepatide from $180/mo, retatrutide from $170/mo
- No subscription, monthly fee or membership — a direct-to-patient model where you pay per medication, and follow-up visits are free
- Free initial consults for first responders, law enforcement, military, nurses and teachers ($0), and $25 for other healthcare workers
- Founded and led by a named family nurse practitioner (Tiffani McKnight, FNP-C) licensed across 30 states/DC, with HIPAA-compliant virtual visits
- HSA/FSA funds and financing accepted, with itemized invoices for HSA/FSA submission
Where it loses points
- Offers compounded retatrutide (labeled "RTT/GLP-3"), an investigational triple agonist not FDA-approved — a higher-risk, less-studied option
- Compounded medications only — no brand-name Wegovy, Zepbound or Ozempic — and compounded GLP-1s aren't FDA-reviewed or approved
- No LegitScript certification shown and no compounding-pharmacy partner named, so the dispensing pharmacy can't be independently verified
- Small, newly established founder-led practice with a thin website and limited public track record or third-party reviews
- Medication prices are "starting at" and billed on top of a one-time consult fee, so the true first-month cost runs higher than the headline
