Pros & Cons Compared

Calibrate

Pros

+2026 pricing rewrite, $199/mo program fee with a 3-month commitment ($597 upfront), then month-to-month; the old $1,649 one-time enrollment fee was removed
+Board-certified physicians with metabolic health specialization lead treatment
+10%+ body-weight-loss guarantee with 50% money-back if not met
+Includes labs, nutrition coaching, personalized smart scale, and sleep/exercise support

Cons

−$597 upfront (3-month commitment) is a meaningful barrier vs. month-to-month competitors
−Medication cost is separate and varies significantly by payer route
−Fewer medications in the menu than larger marketplaces like Ro or Found
−Onboarding still takes 2-3 weeks to complete baseline labs and treatment plan

Oak Longevity

Pros

+$119/mo for compounded semaglutide is among the lowest published entries in our provider table
+No-subscription model, patients are not auto-charged each month, choose to renew manually. Reduces unwanted recurring charges
+Compounded tirzepatide at $185/mo is competitively priced for a GLP-1+GIP dual agonist
+Broadest medication mix on the platform: compounded sema + tirz, oral Wegovy, brand Wegovy/Ozempic/Zepbound/Mounjaro, plus longevity peptides (NAD+, Glutathione, Sermorelin, Tesamorelin)
+Money-back guarantee if not approved by physician, useful safety net for borderline-eligibility patients
+Free shipping and free health coaching included in every program

Cons

−Brand-name pricing ($1,200-$1,500/mo) is significantly above market, NovoCare lists Wegovy pen $199/mo for the first two 0.25 mg or 0.5 mg fills through December 31, 2026, then $349/mo at standard strengths or $399/mo for Wegovy HD; oral pill from $149/mo, dose-dependent and LillyDirect has Zepbound from $299. Use Oak for its compounded tiers and buy brand-name direct
−No published lab panels and no specialty (obesity medicine) physicians disclosed, clinical oversight is lighter than lab-driven platforms
−The 'up to 50% cheaper than competitors' marketing claim is unverified and inconsistent, judge Oak on its posted prices, which are genuinely low, not on the slogan
−The longevity add-ons (NAD+, Sermorelin, Tesamorelin) have limited clinical evidence for weight loss specifically, if weight loss is the goal, the GLP-1 alone does the work and the stack is optional
−Newer brand without disclosed company history, founding date, or executive team on landing pages
−Three-month plans are billed upfront, start on the 1-month plan if you're testing the platform, then bundle once it fits
