Onyx Weight Loss review
Graded on whether a price is published, checkable, and still true at month two — how we grade · how we verify prices
Onyx Weight Loss prices a GLP-1 from $228 a month and a GLP-1 with GIP from $280. Neither page ever says which molecule you would be taking.
Both figures are starting prices for products identified by receptor rather than by drug. Without a molecule named, neither number can be compared with any other seller's price for the same medication.

The verdict
A real clinic with a real address and a published phone number, pricing a drug class rather than a drug. The catalog scans well; the product pages name nothing.

Pros and cons
What we like
- Publishes a street address with a suite number, which almost nothing in this lane does.
- Publishes a telephone number on every page.
- Names its providers on a page of their own rather than describing them as a network.
- Sets four products side by side with a starting price on each.
- Offers the consultation free rather than charging for the quote.
What could be better
- Neither GLP-1 page names the molecule being prescribed.
- Every published figure is a starting price with no ladder or dose band behind it.
- A real price requires booking a consultation and completing an intake in advance.
- No compounding pharmacy is named.
- No statement of which states it can serve appears on any page we read.
What it is
Onyx Weight Loss is a North Carolina clinic with a telehealth front door rather than a telehealth brand with a clinic attached, and the difference shows in what it publishes. A street address with a suite number, a telephone number and a page of named providers all appear on its own site, which puts it ahead of every other company in this lane on the question of who and where.
Its services page sets four products side by side with a starting price on each, which makes the catalog genuinely easy to scan: a GLP-1, a GLP-1 with GIP, phentermine, and a lipotropic injection. Peptides, sermorelin and NAD sit alongside them on separate pages.

| GLP-1 medicationA starting price. The page describes a once-weekly injection or a once-daily tablet and never names the molecule. | not published | $228 | not comparable | September 2026 |
| GLP-1 and GIP medicationA starting price for the dual-agonist product, offered as a weekly injection or a daily sublingual dose, again unnamed. | not published | $280 | not comparable | September 2026 |

What it actually costs at Onyx Weight Loss
Four starting prices on one page: a GLP-1 from $228 a month, a GLP-1 and GIP from $280, phentermine from $129, and a lipotropic injection at a flat monthly rate.
The problem is the two most important pages. Neither GLP-1 page names a molecule. One is headed for the GLP-1 medication and the other for the GLP-1 and GIP medication, each describes the dosing route in general terms — a once-weekly injection or a once-daily tablet, a once-weekly injection or a once-daily sublingual dose — and each leaves the reader to infer whether they are buying compounded semaglutide, compounded tirzepatide or something else. That is not an inference a patient should be asked to make about a prescription, and the molecule is the one detail that decides how a compounded GLP-1 differs from the brand as well as what this price can be compared against.
The one product on the page named by its actual drug is phentermine, which is also the cheapest thing the clinic sells and the only one that is neither a GLP-1 nor a peptide. Every figure across all four products is a starting price, and no page publishes a ladder, a plan length or a dose band behind any of them.
The route to a real quote is a booking flow rather than a page. The clinic's own process is to book a free consultation, complete an intake and consent form at least forty-eight hours beforehand, then meet a provider who builds the plan. That is a reasonable way to run a clinic. It is a poor way to publish a price, and it means the figures on the services page are the beginning of a conversation rather than the end of one.
Who it's wrong for
- Anyone who needs to know which drug they are being prescribed before they book. The GLP-1 pages never name a molecule.
- Anyone comparing against a named compounded semaglutide or tirzepatide price. There is nothing here to compare against.
- Anyone who wants a price without a consultation. Every figure is a starting price and the route to a real one is a booked appointment.
- Anyone who needs the compounding pharmacy named. No page we read names one.
How Onyx Weight Loss works
Book a free consultation
Choose the service you want a consultation for on the clinic's booking site and pick a time. The consultation itself is free.
Complete the intake and consent form
The clinic asks for this at least forty-eight hours before the appointment, so the visit starts from a completed history.
Meet your provider
A named provider builds a plan for you, which is also where an actual price rather than a starting price is arrived at.

Common questions
How much is a GLP-1 at Onyx Weight Loss?
Its services page prices a GLP-1 from $228 a month and a GLP-1 with GIP from $280. Both are starting prices, and the clinic's route to an actual figure is a free consultation followed by a plan built by a provider.
Which GLP-1 does Onyx Weight Loss prescribe?
Neither product page says. One is headed for the GLP-1 medication and the other for the GLP-1 and GIP medication, and both describe the dosing route without ever naming semaglutide, tirzepatide or any other molecule.
Is the Onyx Weight Loss consultation free?
Yes. The clinic's published process is to book a free consultation on its booking site, complete an intake and consent form at least forty-eight hours beforehand, then meet a provider who builds the treatment plan.
Does Onyx Weight Loss have a physical clinic?
Yes, and it publishes the address. A street address with a suite number in Mooresville, North Carolina appears on its own pages alongside a telephone number, which is more than any other company in this group publishes.
What else does Onyx Weight Loss sell?
Beyond the two GLP-1 products, its services page prices phentermine and a lipotropic injection, and separate pages cover peptides, sermorelin and NAD. Phentermine is the only weight-loss item on the services page named by its actual drug.
Why we gave Onyx Weight Loss a C
Read the full grading rationale
Onyx Weight Loss is a North Carolina clinic with a telehealth front door, and it is the only company in this lane that tells you where it physically is: a street address, a suite number and a telephone number, all on its own pages. Its services page lays four products out side by side with a starting price on each, which makes the catalog easy to scan — a GLP-1 from $228 a month, a GLP-1 and GIP combination from $280, phentermine from $129, and a lipotropic injection at a flat monthly rate. The trouble is what the two GLP-1 pages will not say. Neither names a molecule. Both are headed by the receptor rather than the drug, describe the dosing route in general terms, and leave the reader to infer whether they are buying compounded semaglutide, compounded tirzepatide or something else entirely — which is not an inference a patient should be asked to make about a prescription. Every figure is also a starting price with no ladder behind it, and the route to a real quote is a booking flow: the site's own process is book a free consultation, complete an intake form at least forty-eight hours ahead, then meet a provider who builds the plan. That is a reasonable way to run a clinic and a poor way to publish a price.
What that means
Screening is by entity — the company’s own domain plus the address it publishes — never by brand name, because a brand name matches every namesake. Where a company publishes no address, the address half of that match is never exercised, and the result is recorded as the weaker kind of absence rather than a clean record. A known-positive control passed in the same run, so a real match would have surfaced. A letter would be worth knowing about; it would not by itself disqualify a seller.How we reviewed Onyx Weight Loss
- We read the weight-loss services page, both GLP-1 product pages and the homepage in full on 2026-09-12, and took each figure from the page that prints it.
- A nonsense path on the same host in the same session returned a discriminating HTTP 404, so a 200 on this host carries information.
- The two GLP-1 rungs are labeled by the receptor rather than by a molecule, because that is how the pages sell them. Folding them into semaglutide or tirzepatide would put a claim on this clinic its own pages never make.
- The lipotropic product is described here rather than recorded as a rate, because its label falls inside a research subject whose coverage list this lane did not need to extend.
- The FDA warning-letter screen ran on the company's own domain and the Mooresville address printed on its pages, with a known-positive and a known-negative control passing in the same run. It returned no candidate letters, so the address half was never exercised.
