Pros & Cons

1st Optimal

Pros

  • Offers both semaglutide and tirzepatide with injectable and oral formats
  • Functional-medicine approach with at-home labs and blood-work interpretation
  • Unlimited coaching and ongoing support included
  • No long-term contracts
  • Board-certified doctors and nurse practitioners referenced

Cons

  • No public monthly pricing disclosed
  • No published state availability list
  • Compounded vs branded sourcing not clarified on site
  • Pricing only revealed after quiz or consultation

Calibrate Health

Pros

  • Year-long program with 1:1 video coaching, dietitian support, and behavior-change curriculum — a deeper clinical wrap than transactional telehealth
  • $199/month program fee is competitive; medication co-pay can drop to ~$25/month with insurance and a manufacturer savings card
  • Branded GLP-1s only (Wegovy, Ozempic, Zepbound, Foundayo) — no compounded products
  • Insurance navigation team works to maximize coverage and reportedly accepts most major commercial plans
  • Money-back guarantee tied to a 10% weight-loss outcome over the program year
  • Publishes 3-year outcomes data (19% mean weight loss)

Cons

  • 12-month commitment with quarterly billing ($597 every 3 months) — much higher lock-in than month-to-month providers, not refundable mid-program
  • Medication cost is on top of the $199/month fee; cash-pay patients face full manufacturer pricing
  • Insurance navigation only helps if your plan actually covers branded GLP-1s for weight loss — many don't
  • Meaningfully more expensive than compounded telehealth if your insurance denies coverage
  • Distinct from 'Oxford's Medical Weight Loss (The Calibrate Clinic)' — don't confuse the two
