Onyx Weight Loss review

By Derek Olsson ·

Its own treatment pages never name semaglutide or tirzepatide — only "GLP-1 Agonist"

A nurse-practitioner clinic covering eight states, whose three GLP-1 pages never name semaglutide or tirzepatide once — everything is "GLP-1 Agonist." No price appears on any crawlable page; booking runs off-site.

Straight talk: how we earn — some, not all, of these are affiliate links; start a program through one and we may earn a commission at no extra cost to you. Straight about the rest, too: the write-ups say what each provider is actually worth, and a commission does not change a word of them. Full disclosure here.

The verdict

Onyx Weight Loss's most distinctive trait, consistent across every treatment page we checked, is that it never actually names the drug you'd be taking — not semaglutide, not tirzepatide, just "GLP-1 Agonist." That's unusual even among compounded-GLP-1 telehealth sites, most of which name the drug even when they're thin on other disclosures. Combined with pricing that's fully gated behind a booking flow rather than published anywhere, and no LegitScript certification, this is a provider worth asking direct questions of before committing — starting with exactly which drug you'd be prescribed.

Onyx Weight Loss isn't on any of our comparisons yet. The providers we compare in this category are on our semaglutide provider ranking. Nothing on this page is a performance claim — see how semaglutide works for what the treatment does and does not do.

Who it is for, and who it is not

A good fit if

  • You live in one of the 8 states this clinic covers (NC, CO, ME, VT, VA, IA, NH, PA)
  • You want a nurse-practitioner-led clinic with named, credentialed staff
  • You're comfortable booking an appointment before seeing a published price

Look elsewhere if

  • You want the specific drug named before you start the process — the site never says "semaglutide" or "tirzepatide" anywhere
  • You want published pricing before booking — none was found on any crawlable page
  • You live outside its 8-state footprint

What it actually costs

What they advertise

No price published — no dollar figures appear on any crawlable page; booking runs through a separate scheduling platform.

What you actually pay, month to month

Pricing not published on the site; semaglutide has been reported from $228/mo and tirzepatide from $280/mo, but the company doesn't confirm either.

We could not confirm a current price from the public pages we reviewed. We only print a figure the company shows on its own site, never one from a third-party blog. Work out what a vial actually gives you with our peptide dose calculator.

What is included

Compare the total cost, including fees and any minimum commitment. Here is what Onyx Weight Loss bundles in, and what it does not.

Clinician consult

Bloodwork / labs

Follow-ups and dose changes

No cadence published

Human support

Not published

Injection supplies

Not itemized

Shipping

No terms published

Pharmacy, labs and oversight

The pharmacy

Not named on the site; a previously reported Strive Pharmacy partnership isn't confirmed there.

Oversight

No cadence published.

Compounded peptides are not FDA-approved products, and a 503A pharmacy compounds for a named patient while a 503B outsourcing facility manufactures in batches under CGMP. Neither is a quality guarantee on its own — a named facility is simply a fact you can check, and an unnamed “partner pharmacy network” is not. Our guide to verifying a certificate of analysis covers what to ask for.

Where you can get it

North Carolina, Colorado, Maine, Vermont, Virginia, Iowa, New Hampshire, and Pennsylvania — 8 states, confirmed via third-party reports.

The honest cons

The part they would rather you skipped

Onyx Weight Loss's own /glp1, /glp1-gip, and /weightloss pages never name semaglutide or tirzepatide anywhere — a consistent, site-wide pattern of generic "GLP-1 Agonist" language rather than a single omission, worth asking about directly before booking.

  • Never names the specific drug (semaglutide or tirzepatide) anywhere on its treatment pages
  • Pricing fully gated behind a booking flow, not published anywhere crawlable
  • No LegitScript certification found anywhere
  • Serves only 8 states, excluding most of the US

Weigh these trade-offs against the costs, care and terms above. For questions to ask before enrolling, see our vendor red-flags guide.

Read this before you buy

A provider comparison is half the decision. The other half is whether the compound does anything for you at all — and whether it is allowed where you compete. Growth-hormone secretagogues are banned in tested sport, year-round, and a prescription does not change that.
