Arc-1 review
Graded on whether a price is published, checkable, and still true at month two — how we grade · how we verify prices
Arc-1 advertises compounded tirzepatide at $149 a month. Adding the lowest dose to its own cart produced a charge of $199.99 — fifty-one dollars more.
No dose on the selector produced the advertised figure. The collection page prices the product at $199.99 too, so the product page is the outlier.
- Advertised $149, actually $199.99

The verdict
The advertised price is not a price the checkout will take. Two pages on the same site disagree about which states can order, the terms name no jurisdiction, and a banner says the site is under construction while the cart keeps working.

Pros and cons
What we like
- The collection page's figures match what the cart actually charges.
- The consultation fee is stated as zero rather than added later.
- Both product pages publish a state exclusion list rather than discovering it during intake.
- The terms name a legal entity, Arc-1 Metrics, PLLC.
- The product pages say plainly that a licensed medical professional decides whether a prescription is appropriate.
- A 30-day return policy is published.
What could be better
- The tirzepatide product page advertises $149 a month when the cart charges $199.99 for the lowest dose.
- The two product pages give contradictory state exclusion lists, differing on California and Puerto Rico.
- The governing-law clause names the United States and no state.
- The dose selector does not change the price, so "starting at" describes nothing.
- "Month" is attached to what the cart treats as a one-off line item.
- A sitewide banner says the website is under construction while the checkout is live.
What it is
Arc-1 is a longevity storefront selling prescription weight-loss medications alongside supplements and a bio-age calculator. The weight-loss collection holds compounded semaglutide, compounded tirzepatide, metformin and low-dose naltrexone, each as a product page with a dose selector and an Add To Cart button. The terms name Arc-1 Metrics, PLLC.
It runs as an ordinary e-commerce checkout with a prescription step bolted on: the product page tells you to add the item to the cart, complete checkout to reach the intake form, and receive the prescription after a licensed practitioner reviews it. The consultation fee is stated as $0.
A banner repeated eleven times down every page reads "Website under construction for a better patient experience." That would be unremarkable on a brochure site. It is on a store that is taking card payments for prescription drugs.

What it actually costs
The tirzepatide page says "Starting at $149/month". The collection page prices the same product "From $199.99". The cart charged $199.99 for the lowest dose.
We resolved the disagreement the only way it can be resolved, by adding the product to the cart and reading the cart. Compounded tirzepatide at 2.5 mg — the lowest dose the selector offers — came back at $199.99, and compounded semaglutide at 0.5 mg came back at $199.99 as well. The collection page agrees with the cart. The tirzepatide product page, the one a shopper lands on from a search, does not, and its figure is fifty-one dollars below anything the checkout will accept.
The dose selector changes nothing. Clicking through 0.5 mg, 1 mg and 2.5 mg on the semaglutide page, and 2.5, 5 and 7.5 mg on the tirzepatide page, left the displayed figure identical each time, so "starting at" does not describe a range that opens upward from a real entry price — it describes a number that appears on the page and nowhere in the transaction. That is exactly the pattern that makes an advertised GLP-1 price meaningless.
Read the same day, the two product pages disagree about California: the semaglutide page will sell there and the tirzepatide page will not.
The semaglutide page says the product is "not available in Arkansas, Indiana, Minnesota, Puerto Rico, or South Carolina." The tirzepatide page says "Not available in California, Arkansas, Indiana, Minnesota, or South Carolina." California is on one list and absent from the other; Puerto Rico is the reverse. One of those two sentences is wrong about the largest state in the country, and a reader has no way to tell which.
The legal page compounds it. Arc-1's terms of service say the agreement is "governed by and construed in accordance with the laws of the United States" — naming no state, when contract law in the United States is state law. It is not a clause a customer could act on.
Who it's wrong for
- Anyone budgeting off the advertised figure. $149 is not a price this checkout charges for any dose we could select.
- Anyone in California. One product page excludes the state and the other does not, and the site never reconciles them.
- Anyone who expects the dose selector to change the price. It does not, on either product.
- Anyone who wants to know which state's law governs a dispute. The terms name a country, not a jurisdiction.
- Anyone uneasy about buying prescription drugs from a store that says on every page that it is under construction.
How Arc-1 works
Pick a product and a weekly dose
The selector offers three doses for each GLP-1. The displayed price is the same whichever one is chosen.
Add to cart
This is an ordinary storefront cart, not a plan screen. The cart is where the price that will be charged first becomes visible.
Complete checkout to reach the intake
The product page says checkout comes before the intake form, and that the consultation fee is zero.
A practitioner reviews it
The page says a licensed medical professional determines whether a prescription is appropriate, and lists the states where the product is unavailable.

Is Arc-1 legit?
Arc-1 is operated by Arc-1 Metrics, PLLC. We read that off the company’s own terms of service on September 2026.
What that means
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.Pharmacy, prescribers and safety checks

Common questions
How much does Arc-1 tirzepatide really cost?
$199.99 for the lowest dose, which is what its collection page says and what its own cart charged when we added the product. The tirzepatide product page advertises $149 a month, and no dose on the selector produced that figure.
Does the Arc-1 price change with the dose?
No. We clicked through every dose on both GLP-1 product pages — 0.5 mg, 1 mg and 2.5 mg for semaglutide, and 2.5, 5 and 7.5 mg for tirzepatide — and the displayed price did not change once.
Can I order Arc-1 in California?
Its own pages disagree. Read on the same day, the compounded semaglutide page excludes Arkansas, Indiana, Minnesota, Puerto Rico and South Carolina, while the compounded tirzepatide page excludes California, Arkansas, Indiana, Minnesota and South Carolina. One of the two is wrong and the site does not say which.
What law governs an Arc-1 order?
The terms of service say the agreement is governed by "the laws of the United States" and name no state. Contract law in the United States is state law, so that clause does not identify a jurisdiction a customer could bring a claim in.
Is Arc-1 a subscription?
The product pages attach the word "month" to the price, but the checkout is an ordinary storefront cart and the cart line showed a single charge for the item rather than a recurring plan. The site does not explain the difference anywhere we read.
Why we gave Arc-1 a F
Read the full grading rationale
The advertised price is not the price. Arc-1's tirzepatide product page says "Delivered to you. No insurance required. Starting at $149/month"; its own collection page prices the same product "From $199.99"; and when we added the lowest dose to the cart, the cart charged $199.99. The $149 is fifty-one dollars below anything the checkout will take, and it is the figure on the page a shopper lands on. Compounded semaglutide behaves the same way at $199.99 and metformin at $179.99, neither with a per-month claim the store actually supports — the word "month" is attached to what the cart treats as a one-off line item, and no dose option on either product page changes the figure. The company also cannot keep its own map straight: read the same day, the semaglutide page excludes Arkansas, Indiana, Minnesota, Puerto Rico and South Carolina, while the tirzepatide page excludes California, Arkansas, Indiana, Minnesota and South Carolina. California is on one list and not the other, which means one of the two pages is wrong about whether the largest state in the country can order. Its terms name Arc-1 Metrics, PLLC and then say the agreement is "governed by and construed in accordance with the laws of the United States" — naming no state, when contract law is state law. And a banner repeated eleven times down every page says the website is under construction. A store that is still taking money is not under construction as far as the customer's card is concerned.
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 Arc-1
- We read the weight-loss collection page, both GLP-1 product pages and the terms of service in full on 2026-09-11.
- Where the product page and the collection page disagreed, we settled it by adding each product to the cart at its lowest dose and reading what the cart said. The cart charged $199.99 for both. We did not proceed to checkout and entered no payment details.
- The cart URL is deliberately not cited as a source for any figure here, because what a cart shows depends on what was put in it. The rungs are sourced to the collection page, which is a stable public path that agrees with what the cart charged.
- We clicked every dose option on both product pages and recorded that the displayed price was unchanged each time, rather than assuming a "starting at" price implied a range.
- A nonsense path on the same host returned a genuine 404 page in the same session.
- The FDA warning-letter screen ran on the entity domain alone, as no address is published, with a known-positive and a known-negative control passing in the same run. No candidate letters came back.
