Certification: Arc-1 publishes a LegitScript certification on its own pages. Where it ships: The site doesn't say which states it serves. Last checked: July 2026, against Arc-1's own pages. Published price: Arc-1 publishes a figure for semaglutide and tirzepatide — the qualifiers are in "What does Arc-1 cost?" below. What it sells: Compounded medication only, injectable route only. Licensing & trust: 63/100 on the scored dimension of that name — one of the six in our published methodology. Checks out as far as the figures go, with one caveat: every price Arc-1 publishes carries a condition, so the number on the site is not the monthly bill.

Arc-1

Q: What does Arc-1 cost?

Semaglutide: $200/mo (0.5 mg dose, compounded). That is a starting figure, not the price at every dose: $200 a month is the lowest rung, and the cost rises from there. Because that figure carries a condition, it is held out of our "cheapest" rankings and out of the median we compute for semaglutide — only flat month-to-month rates compete there. Tirzepatide: $200/mo (2.5 mg dose, compounded). That is a starting figure, not the price at every dose: $200 a month is the lowest rung, and the cost rises from there. Because that figure carries a condition, it is held out of our "cheapest" rankings and out of the median we compute for tirzepatide — only flat month-to-month rates compete there. All figures as published on Arc-1's own site and read in July 2026. Prices change — confirm before you order.

Arc-1 offers compounded semaglutide (from $249.99) and compounded tirzepatide (from $299.99) as per-dose purchases, not monthly subscriptions.
