at 4mg/week and $10/mg (~4.33 weeks per month).
≈ $173/mo vs ~$1,100–1,400/mo projected brand price — about 86% less.
Brand retatrutide is not yet approved or priced; the $1,100–1,400/mo figure is an industry projection, not an actual list price.
A 20mg vial holds ~5 weeks of supply at 4mg/week, but reconstituted retatrutide is generally only stable ~28–30 days. You likely won't use the whole vial within the stability window, so some product may be wasted — consider a smaller vial. See our reconstitution guides for storage details.

Each cell = weekly dose (mg) × price per mg × 4.33 weeks, rounded to the nearest dollar. Compounded research prices typically range $8.33–$15 per mg; figures are estimates, not a quote.
The Cost Formula
Monthly cost
monthly cost = weekly dose (mg) × price per mg ($) × 4.33 weeks
A month averages 4.33 weeks (52 weeks ÷ 12 months), so a once-weekly injection schedule uses 4.33 doses per month.
Cost per mg
cost per mg ($) = vial price ($) ÷ vial size (mg)
Larger vials (e.g. 30mg or 60mg) usually carry a lower cost per mg, so buying a bigger vial often reduces your monthly cost at the same dose.
Frequently Asked Questions
How much does retatrutide cost per month?
Estimated at roughly $150–$520 per month for typical maintenance doses. At US compounded prices of about $8.33–$15 per mg, a 4mg weekly dose runs ~$144–$260/mo and an 8mg weekly dose runs ~$289–$520/mo (weekly dose × price per mg × 4.33 weeks). This compares to a projected brand price of roughly $1,100–$1,400/mo once retatrutide reaches market. Figures are research estimates, not a quote.
What is retatrutide's cost per mg?
Approximately $8.33–$15 per mg at current US compounded research pricing, depending on vial size and supplier. Cost per mg = vial price ÷ vial size, so larger vials (e.g. 30mg or 60mg) generally lower the per-mg cost. Use the calculator above with your own vial price and size to get an exact figure. These are estimates for research-use products, not retail medical pricing.
How much is retatrutide 30mg or 60mg?
A 30mg vial at $8.33–$15 per mg works out to roughly $250–$450, and a 60mg vial to roughly $500–$900, depending on supplier and bulk discounts. Larger vials usually carry a lower cost per mg, so a 60mg vial is often the most cost-effective for maintenance dosing. Enter the vial price and size into the calculator to confirm your per-mg cost. Estimates only — request a current quote for exact pricing.
Is retatrutide cheaper than Ozempic or Wegovy?
At compounded research prices, retatrutide is estimated at ~$150–$520/mo for typical doses, which is generally below the ~$900–$1,350/mo US list price of brand Ozempic or Wegovy without insurance. However, retatrutide is investigational and not yet FDA approved, so its eventual brand price (projected ~$1,100–$1,400/mo) is unknown. Compare your specific dose using the calculator above. Estimate only, not medical or pricing advice.
How much is retatrutide without insurance?
Because retatrutide is investigational and not FDA approved, there is no insurance coverage — all current access is self-pay. At US compounded research prices that means an estimated ~$150–$520/mo for typical 4–8mg weekly doses, far below the projected ~$1,100–$1,400/mo brand price. Use the calculator above to estimate your own out-of-pocket monthly cost. These are estimates, not a quote or medical advice.
