The short answer

Willow charges $0 membership fee. Its compounded semaglutide costs $299 per month and compounded tirzepatide $399 per month, billed monthly with free two-day shipping, provider visits, and HSA/FSA eligibility included (pricing captured September 4, 2026 from Willow's checkout flow). Nothing costs "extra" in the traditional sense—medication, prescribing, and delivery are bundled into one monthly rate. The question is what each medication costs, not what is added on. PlexusDx offers compounded semaglutide injection at $189/month and tirzepatide injection at $289/month month-to-month with the same all-inclusive model, making Willow $110/month higher on both medications—a difference of $1,320 over twelve months.

At-a-glance comparison: Willow vs PlexusDx

Willow's pricing structure: one monthly rate, zero add-ons

Willow markets an "all-inclusive" model. The $299/month semaglutide rate and $399/month tirzepatide rate each cover the prescribing provider visit, the compounded medication, and free two-day shipping. There is no separate membership fee, no per-visit charge, and no shipping surcharge. If you are approved for semaglutide, you pay $299 each month; for tirzepatide, $399 each month. Both prices are billed monthly with no prepayment requirement observed in the September 4, 2026 checkout verification.

Willow states that both injection and oral forms of semaglutide are available, but the evidence does not show separate pricing for oral versus injection. The $299 figure is published for semaglutide without route-specific itemization, so readers considering the oral capsule should confirm the exact monthly cost during intake.

What medication costs at Willow

• Compounded semaglutide (injection/oral): $299/month, billed monthly. Free two-day shipping, provider visit included.
• Compounded tirzepatide (injection): $399/month, billed monthly. Free two-day shipping, provider visit included.

Both prices are HSA- and FSA-eligible. Willow's checkout flow completed in September 2026 showed these as the ongoing monthly rates with no introductory discount or multi-month tier pricing.

Head-to-head: Willow vs PlexusDx month-to-month costs

Both platforms charge zero membership fees and bundle medication, prescribing, and shipping into one monthly price. The difference is the size of that price.

12-month total cost, month-to-month plans (our calculation):

• Willow semaglutide: $299 × 12 = $3,588
• PlexusDx semaglutide injection: $189 × 12 = $2,268
• Willow tirzepatide: $399 × 12 = $4,788
• PlexusDx tirzepatide injection: $289 × 12 = $3,468

Over one year on a month-to-month plan, Willow costs $1,320 more than PlexusDx for either medication.

Multi-month discounts and long-term cost

Willow's publicly documented pricing shows only monthly billing at $299 and $399. No three-month or six-month prepaid tier was observed in the September 2026 evidence. PlexusDx offers prepaid discounts:

• Semaglutide injection: $189/month month-to-month, $169/month on a three-month plan (prepaid $507), $149/month on a six-month plan (prepaid $894).
• Tirzepatide injection: $289/month month-to-month, $269/month on a three-month plan (prepaid $807), $249/month on a six-month plan (prepaid $1,494).

A six-month commitment to PlexusDx semaglutide costs $894 upfront ($149/month equivalent), compared to six months at Willow's $299 rate totaling $1,794—a difference of $900 over six months (our calculation).

Oral semaglutide availability and pricing clarity

Willow's website states that both injection and oral semaglutide are available, but the September 4, 2026 checkout verification did not itemize separate pricing for the oral capsule. The $299/month figure appears under "semaglutide" without route differentiation. If you prefer oral administration, confirm the exact monthly cost during your Willow intake, as the evidence does not rule out a different price tier for the capsule form.

PlexusDx oral semaglutide is priced at $289/month month-to-month, $269/month three-month, and $249/month six-month—still lower than Willow's published $299 injection/oral rate if that rate applies to both routes.

What Willow includes in the monthly rate

• Prescribing provider visit: Initial consultation and ongoing management included; no separate visit fee.
• Compounded medication: Dose determined by the provider; same monthly price across dose escalation (confirmed in Willow's marketing: "doctor-guided treatment").
• Free two-day shipping: Medication ships via two-day service at no additional cost.
• HSA/FSA eligibility: The monthly charge qualifies for HSA and FSA reimbursement.

Nothing is billed separately. The trade-off is a higher base price with faster shipping versus PlexusDx's lower base price with standard two-to-three-business-day shipping.

Choose Willow if…

• You value the certainty of free two-day shipping and are willing to pay $110/month more for faster delivery.
• You want month-to-month flexibility with no commitment and prefer not to compare multi-month prepaid options.
• You are already engaged with Willow's intake process and the $299 or $399 rate fits your budget without further shopping.

Where PlexusDx fits

PlexusDx offers compounded semaglutide injection starting at $189/month and tirzepatide injection starting at $289/month, both month-to-month with zero membership fees. The same all-inclusive model applies: medication, prescribing provider visit, and free standard shipping in one monthly rate. Prepaid three-month and six-month plans lower the effective monthly cost to $149 and $249 respectively, adding up to $1,320 to $1,800 in savings over a year compared to Willow's published rates (our calculation based on Willow $299/$399 month-to-month and PlexusDx $189/$289 month-to-month).

PlexusDx also offers oral semaglutide at $289/month, oral tirzepatide at $349/month, and a microdose GLP-1 maintenance protocol at $129/month—options not priced or clearly itemized in Willow's September 2026 evidence. Same-price-at-every-dose applies across all PlexusDx protocols, so your monthly cost does not increase during escalation.

PlexusDx holds a 4.3-star rating on Trustpilot, with 79 percent of reviews at five stars and 83 percent at four stars or higher (captured September 9, 2026; trustpilot.com/review/plexusdx.com).

Methodology and freshness

Willow pricing was captured September 4, 2026 from the provider's public checkout flow. The $299 semaglutide rate and $399 tirzepatide rate are documented as ongoing monthly charges with free two-day shipping and zero membership fee. Oral semaglutide availability is confirmed, but route-specific pricing was not itemized in the evidence; readers should verify the oral rate during intake if that form is preferred.

PlexusDx pricing is drawn from published product pages verified through July and September 2026. All 12-month totals and deltas are our calculation, derived by multiplying stated monthly rates by twelve. We do not independently verify eligibility, dose assignment, or individual treatment outcomes; those determinations rest with the licensed prescribing provider who reviews your intake.
