Arc-1
A Las Vegas longevity store run by a physician-founder, selling compounded GLP-1s, sermorelin, NAD+ and glutathione as single orders you pay for before any intake.
Review by Molly Ward, goal-guide writer · Updated September 2026
The short version
You pay first, then a practitioner you cannot name reviews your intake form. The founder is a named, board-certified OB/GYN, and after approval you can message your prescribing clinician from your order. The weak spots are the paperwork: an unnamed pharmacy, a 30-day guarantee the support page partly takes back, and a tirzepatide headline lower than the cart.

Visit Arc-1 →Arc-1 is a cash-pay online store for longevity and weight-loss prescriptions. It is run by Arc-1 Metrics, PLLC, of Las Vegas, Nevada. Five of its products are peptides: compounded semaglutide and tirzepatide injections, sermorelin injections, NAD+ as an injection or a nasal spray, and glutathione injections. The rest of the catalog is outside what this site covers.

The tirzepatide is a blend the page lists as "Tirzepatide + Glycine + B12 (10mg/5mg/500mcg per mL)". Its page gives no dosing schedule. The semaglutide page says it is "offered temporarily due to the shortage" of Wegovy.

- Injection (compounded)From $389.99/mo
- NAD+Legal to compound
- Injection (compounded)From $299.99/mo

NAD+ injections are $299.99 for a 6 mL vial, dosed as "3 - 100mg Doses per Week". NAD+ nasal spray is $149.99 for a 6 mL bottle of about 150 sprays, used "1-2 sprays per day for 30 Days". Glutathione injections are $389.99 for a 30 mL vial, listed as "400mg" at "3 Times Per Week". Each page also shows a lower "with subscription" figure you cannot choose at checkout.
Recovery
- SermorelinLegal to compound
- Injection (compounded)From $299.99/mo
Sermorelin injections are $299.99 at "300mcg Nightly Monday-Friday" and $399.99 at 450 mcg on the same schedule. The page lists "Supports Muscle Health and Recovery" among its benefits, with no study cited.
Sleep
- SermorelinLegal to compound
- Injection (compounded)From $299.99/mo
The sermorelin page pitches it for sleep too. It lists "Enhances Sleep Quality" and its FAQ says many people notice better sleep quality "within a few weeks". No source is given for either line.
Each “From” figure is the seller’s own starting price, in the unit the seller states. Where a required fee or a package length changes what one month costs, the smaller line under it is our arithmetic, not a figure the seller prints. Compounded preparations are not FDA-approved.
Who prescribes
A licensed clinician
The site does not name who reviews your order. The homepage says each request is reviewed by one of its board-certified physicians. The tirzepatide page says it is "prescribed by licensed medical providers and dispensed by US-licensed compounding pharmacies". Neither names a clinician, a state license or a pharmacy. The founder is named. He is Dr. Todd A. Stearns, DO, FACOG, a board-certified obstetrician and gynecologist. His page says he practices in Nevada and teaches resident physicians. That page is headed "Dr. Todd Stearns, MD" while his own credentials list reads DO. The site never says he reviews your intake himself.
The order runs backwards from a clinic visit. You add a product to your cart and pay, and only then reach the intake. The product pages spell it out: "Complete Checkout ($0 consultation fee)", then "Finish Intake Form", then "Receive Your Prescription". A practitioner reviews the form. If they have questions, the site's process page says they may contact you "through a telehealth chat, a phone call, or a video consultation, depending on what's required." So a live call happens only when the practitioner asks for one. You can also book a 20-minute consultation with the founder from the homepage. It opens a separate booking form, and no price for it is shown. After approval you get ongoing access to your prescriber. Your account has a Chat with Doctor button on each order, which the support page says "sends your message directly and securely to your prescribing clinician." Replies are promised within one business day.
Are labs required?
Not asked for peptides
No bloodwork is asked for before any peptide on the site. The support page says test results and clinician notes appear in your account when a lab is ordered. Enclomiphene, which this site does not cover, is marked as needing a blood test first.

What it claims, and what it cites
The strongest claims sit in the FAQs, and some contradict the product pages beside them. The weight-loss FAQ says both semaglutide and tirzepatide "are approved by the Food and Drug Administration (FDA)". The tirzepatide page itself says compounded medications "are not FDA-approved". What Arc-1 sells is compounded, so the second statement is the one that applies to you. The semaglutide page says the product "is offered temporarily due to the shortage of FDA-approved Semaglutide medications like Wegovy®." FDA has since declared that shortage resolved, as our guide on B12 in compounded GLP-1s explains. The page does not say what its rationale is now. The tirzepatide FAQ says the compounded version is "just as effective as branded options like compounded Wegovy". Wegovy is a semaglutide brand, and no comparison is cited. The page also calls tirzepatide "a GLP-1 receptor agonist" and says it "May help patients lose up to 10–15% of body weight", again with no source. The trust badges are stated on every page: "US-Licensed Pharmacies", "Board Certified Physicians" and "LegitScript Certified". The LegitScript seal links to LegitScript's own lookup for Arc-1. The pharmacy badge names no pharmacy. The homepage quotes one customer who "lost 17 pounds in 2 months". It gives no product, dose or name.

How it bills
Every product is sold as a single order at the price shown in the cart. No product offers a subscription at checkout, although each page shows a lower "As low as … per month with subscription" figure. The support page sends refills through a Manage Subscription button in your account. The consultation is stated as $0, and shipping is free. The homepage lists "No Hidden Fees". The 30-day guarantee needs reading closely. Each product page promises "30-Day Satisfaction Guarantee". The refund policy accepts returns only if the item is unused and in its original packaging. The support page adds: "In general, prescriptions are not returnable." Approved refunds are paid "within 6-8 weeks".
