Harbor review

What it is

Harbor is run by Harbor Health Inc., a Delaware corporation that also trades as Arbor and operates a near-identical site under that name; its legal pages use the Arbor name throughout. It describes itself as a technology platform rather than a medical practice. Consultations are provided through its partner medical group, MD Integrations, whose patient portal members use, and prescriptions go to partner pharmacies it doesn't name. It focuses on compounded GLP-1s and also sells sermorelin, NAD⁺ and glutathione. You must be 18 or older and in the United States, and its terms make no promise that care is available in every state; its FAQ says it serves every state where telehealth prescribing of compounded GLP-1s is allowed. Support is by text and email, and its marketing cites a 94.6% success rate and 10,000 members, figures it reports itself.

How it works

You start with an eligibility quiz of a couple of minutes, then a fuller health questionnaire of about ten minutes, and pay at checkout. A clinician licensed in your state reviews your information and decides whether treatment is appropriate; depending on your state and history, you may need a live audio or video visit first. If you're approved, the medication ships free by FedEx, usually arriving within about 48 hours. After that, you can reach a clinician through the portal at any hour, periodic consultations happen roughly every three months, and each refill is reviewed before it ships. When you reach your goal, the plan is a supervised taper off the medication followed by optional registered-dietitian support with macros or meal plans. To cancel, you message the support team; canceling before your renewal date stops the next charge, and your plan runs to the end of the current period.

Pricing transparency

Harbor advertises compounded semaglutide from $99 a month and compounded tirzepatide from $149 a month, with no membership fee and no price increase as your dose rises. The price covers the medication, clinician consultations, check-ins, dose changes and shipping. Its billing terms describe monthly plans plus discounted prepaid plans billed every three, six or twelve months, and the homepage presents both figures as "as low as" prices, so the plan length that the $99 and $149 apply to isn't spelled out; check it at checkout. Its terms describe medication shipments about every 28 days, which works out to 13 shipments a year. The refund rules are specific: if you cancel before a prescription is written, you get your money back minus a $100 clinician consult fee; once it's written, the payment is non-refundable, including unshipped months of a prepaid plan; and if a clinician doesn't approve you, the refund is full. The 12-month money-back guarantee refunds your subscription fees only if you are a new customer, stay enrolled for 12 straight months, take all 13 shipments, follow the dosing and miss a target weight set at enrollment, with a claim filed within 35 days. HSA and FSA cards are accepted, insurance isn't, and pay-over-time financing is offered.

Branded vs compounded

Harbor prescribes compounded semaglutide and compounded tirzepatide as weekly injections, with the dose raised gradually under a clinician's guidance. Its product pages say the medication is compounded by licensed 503A and 503B pharmacies in the United States, without naming them, and that each batch is tested for purity and potency. Its FAQ notes that compounded prescriptions are written for a specific compounding pharmacy and can't be moved to a retail pharmacy. The site displays a LegitScript certification seal. No FDA warning letter has been issued to it. Compounded drugs are not FDA-approved, which its footer states. If you want to know which pharmacy will fill your order, ask before you pay.

Pros and watch-outs

The evidence behind what Harbor prescribes

We grade the molecules, not the marketing. Here is what the human data actually shows for each thing on their menu.

• What the semaglutide weight-loss trials actually showed

  STEP 1, STEP 4, and SELECT — the efficacy, the rebound, and the cardiovascular signal, read straight from the primary literature.

• Tirzepatide vs semaglutide for weight loss: what the trials actually support

  Most comparisons are cross-trial. Only SURPASS-2 and SURMOUNT-5 randomized one drug against the other — here's the precise distinction.

• Compounded vs branded GLP-1: regulatory status, sourcing and the evidence

  Compounded GLP-1 isn't FDA-approved, the shortage exception behind it ended in 2025, the FDA moved against mass-marketed copies in 2026, and the trial data belong to the branded product. Here's the precise picture.
