Compounded tirzepatide
Arc-1 review
Arc-1's tirzepatide headline says $149 a month, but the store prices the 2.5 mg vial at $200. Higher doses cost more, and 7.5 mg is the ceiling at $400. Shipping is free and expedited, and the medical intake comes after you pay.
Who it suits
Good fit if
- You want to buy a vial the way you'd buy anything online, then fill in the health questions.
- You're comfortable with a formula that adds glycine and vitamin B12 to the tirzepatide.
Look elsewhere if
- You expect to need more than 7.5 mg a week, the highest dose Arc-1 sells.
- You're budgeting from the $149 headline, since no dose is priced that low.
- You live in California, Arkansas, Indiana, Minnesota or South Carolina.
What you get
Arc-1 sells three strengths of compounded tirzepatide: 2.5 mg, 5 mg and 7.5 mg. Each vial is mixed with glycine and B12, at 10 mg of tirzepatide per mL. The 2.5 mg order is $200, and the price steps up with each dose to $400 at 7.5 mg.
The product page offers a plain Add To Cart purchase, with no subscription option shown. Shipping is free and expedited, and a customer review on the page describes the box arriving with cold packs. US-licensed compounding pharmacies dispense the prescription, though the page doesn't say which ones.
How it works
- Choose 2.5 mg, 5 mg or 7.5 mg on the tirzepatide page and check out.

- A licensed provider reviews it and may contact you by chat, phone or video with questions.
- Once approved, the order ships quickly in discreet packaging.
- For a refill, sign in and use the Manage Subscription button, which Arc-1's support page points to.
Pros and cons
Pros
- Every tirzepatide order ships free by expedited delivery, according to Arc-1's product page.
- The page spells out the formula per mL: 10 mg tirzepatide, 5 mg glycine and 500 mcg B12.
- The founder, Dr. Todd Stearns, is a board-certified OB-GYN practicing at MountainView Hospital in Las Vegas.
Cons
- The page headline says $149 a month, yet the cheapest dose the store sells is $200.
- Arc-1 tops out at 7.5 mg, so anyone titrating past that dose will need another seller.
- Tirzepatide isn't sold in California, Arkansas, Indiana, Minnesota or South Carolina.
Check before you pay
- Which price you'll pay
- Pick your dose and read the cart total before paying. The 2.5 mg vial is $200, not the $149 in the headline.
- The 30-day guarantee
- Arc-1's support page says prescriptions generally can't be returned. Its refund policy also excludes perishable and personal care goods. Ask how the 30-day guarantee applies to an opened vial.
- Refill timing
- Refill requests take up to two business days to process. Order your next vial before the current one runs out.

Arc-1 questions
- Is Arc-1 legit?
- Arc-1 says it is LegitScript certified and HIPAA compliant. Licensed providers review each intake before anything ships. The tirzepatide is compounded by US-licensed pharmacies, so it is not Zepbound or Mounjaro and has no FDA approval, as the product page states.
- How much is Arc-1 tirzepatide per month?
- The 2.5 mg vial is $200, and the page calls that a month's supply. Prices rise with the dose, reaching $400 for 7.5 mg. The $149 headline doesn't match the price of any dose.
- Does Arc-1 take insurance for tirzepatide?
- No. Arc-1 sells tirzepatide as a cash purchase and says no insurance is required.
- What doses of tirzepatide does Arc-1 sell?
- Three: 2.5 mg, 5 mg and 7.5 mg. There's no 10 mg, 12.5 mg or 15 mg option on the product page.
