Pros & Cons Compared
Oak Longevity
Pros
- +$130/mo for compounded semaglutide is among the cheapest entries on the market — Sprout Health ($99) and Sesame Care ($99) are lower, but Oak undercuts most mid-tier platforms
- +Compounded tirzepatide at $199/mo is competitively priced for a GLP-1+GIP dual agonist
- +No-subscription model — patients are not auto-charged each month, choose to renew manually. Reduces unwanted recurring charges
- +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 direct pricing for Wegovy is $349/mo, LillyDirect Zepbound $299/mo. Never buy brand-name through Oak
- −No published lab panels, no specialty (obesity medicine) physicians disclosed — clinical depth is shallow
- −'Up to 50% cheaper than competitors' marketing claim is unverified and inconsistent — depends on which competitor and which medication tier
- −'Longevity' framing pushes users toward add-on products (NAD+, Sermorelin, Tesamorelin) that have limited clinical evidence for weight loss specifically
- −Newer brand without disclosed company history, founding date, or executive team on landing pages
- −Three-month plans are billed upfront — pricing transparency is good, but commit-up-front is a friction point for users testing the platform
Willow
Pros
- +Includes monthly provider check-ins and dose adjustments at no extra cost
- +Offers both injectable AND oral compounded semaglutide — one of few platforms with a daily oral tablet option
- +$299/mo all-in for compounded semaglutide with monthly provider support
- +90%+ patient retention rate after 3 months per their published outcomes data
Cons
- −Compounded-only — no brand-name Wegovy or Zepbound through the platform
- −Tirzepatide pricing reaches $499-$524 at higher doses — starting dose is $399/mo
- −Cash-pay only — no insurance billing, though they provide superbills for FSA/HSA
- −Founded in 2024 — less track record than Ro or Hims, though growth has been fast
