Provider review
Arc-1 review
Advertises "from $149.99/mo"; its own product data shows a $199.99 floor
Arc-1 now names both a legal entity, Arc-1 Metrics, PLLC, with a Las Vegas, NV address, and a founder, Dr. Todd Stearns, DO, FACOG, independently confirmed as a real, licensed, currently-practicing physician (though board-certified in OB/GYN, not obesity medicine specifically) — both corrections to prior research, which had recorded neither as disclosed. Pricing is per-dose rather than subscription-based: compounded semaglutide runs $199.99 at 0.5mg up to $549.99 at 2.5mg, and compounded tirzepatide runs $199.99 at 2.5mg up to $399.99 at 7.5mg, confirmed live in the site's own product data. The site-wide banner advertises "GLP-1s starting at $149.99/month," confirmed live — but the actual lowest price in the product data is $199.99, a real $50 gap between the advertised floor and the true one. A LegitScript badge is displayed, confirmed live, and the underlying commerce backend's vendor field reads "Strive" rather than "Arc-1," consistent with a shared white-label telehealth platform rather than a fully bespoke one.
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
Arc-1 discloses more than prior research had credited it for — a real legal entity and a real, independently verifiable founder-physician, genuine updates worth knowing. But its current site-wide banner advertises "starting at $149.99/month" while the actual lowest price anywhere in its own product data is $199.99, confirmed live — a real, current $50 gap between the teaser and the floor, on top of per-dose pricing that climbs steeply at higher doses (up to $549.99 for semaglutide, $399.99 for tirzepatide).
Arc-1 is not ranked on any of our boards. This is a standalone read of what the company publishes about itself — the providers we do rank in this category are on our semaglutide provider ranking. Nothing on this page is a performance claim — see the evidence review for what these compounds do and do not do.
Who it is for, and who it is not
A good fit if
- You want per-dose purchasing rather than a subscription commitment
- You want a named, independently verifiable founder-physician rather than an anonymous operation
- You're comparing this alongside its broader longevity menu (rapamycin, NAD+, sermorelin)
Look elsewhere if
- You're budgeting off the "$149.99/mo" banner — the actual lowest price anywhere is $199.99
- You want a compounding pharmacy individually named — only generic "US-Licensed Pharmacies" language appears
- You want the founder's board certification to be obesity-medicine specific — it's OB/GYN

Pharmacy, labs and oversight

Oversight

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.

The honest cons
The part they would rather you skipped
Arc-1's site-wide banner advertises "GLP-1s starting at $149.99/month," confirmed live, but the actual lowest price found anywhere in the site's own product data is $199.99 — a real $50 gap between what the banner promises and what you'd actually pay at the cheapest dose.
- Site banner advertises a $149.99/mo floor that doesn't match the real $199.99 lowest price
- Per-dose pricing climbs steeply — up to $549.99/mo for semaglutide at 2.5mg
- Compounding pharmacy never individually named
- Founder's board certification (OB/GYN) isn't obesity-medicine specific
None of this is unique to Arc-1 — the whole category shares it. What we hold against a provider is the part it hides, and the ways vendors hide things are catalogued in our vendor red-flags guide.
How it compares
The providers we rank on our semaglutide provider ranking, in the order that board ranks them. Arc-1 is not among them: it is reviewed here, not ranked there, and we would rather show you the comparison than pretend the two are the same thing.
- BHBodybuilding Health+One of the deepest peptide catalogues here, and the loosest one
- Enhance MDWrites a flat-price-at-every-dose policy down — and charges near the top for it
- RxSpan MDOral tablet only, at a real $179 monthly rate
- Direct MedsThe plainest price mechanics on either board, from a company with an FDA warning letter
- Synergy RxPublishes a starting number, and nothing about what it commits you to
- Sprout HealthA $150 markdown the site never explains, and a semaglutide price quoted by the quarter
- Strut HealthInjection or troche, but $119 is the auto-refill price only
- MadeMedPrices are published — but there is no monthly option at all

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.
