What one vial costs you. There is no approved list price for retatrutide, so use the price you were actually quoted.
Retatrutide is an experimental compound and the FDA has not approved it. This calculator gives an estimate for research reference only. It is not medical advice and it is not a price quote.

How the retatrutide cost calculator works
Every result comes from three numbers you enter: the vial size, what you paid for it, and how much you use each week. For research reference only.
Enter your vial size and price
Pick the vial size you are pricing, anywhere from 5 mg to 40 mg, then type in what one vial costs you. There is no approved list price for retatrutide, so use the price you were actually quoted, not a number you read in an article.
Add your weekly amount
Type in how many milligrams a week you are pricing out. The calculator never suggests an amount. It only takes the number you enter and works out what it costs.
Read your cost per mg and per month
The tool divides what you spent by the milligrams you got, which gives your cost per mg. It then multiplies that by your weekly amount to show the cost per dose, per month, and per year.
Retatrutide Cost Per mg Explained
A vial price only means something once you break it down per milligram. That one number is what lets you compare any two retatrutide offers.
Cost per mg is the only fair comparison
A $120 vial and a $260 vial tell you nothing on their own. You need to know how many milligrams are inside each one. Divide the price by the vial size and you get the retatrutide cost per mg, which works for any vial size.
Bigger vials usually cost less per mg
A 30 mg or 40 mg vial almost always costs less per mg than a 5 mg or 10 mg vial, even though the price tag looks bigger. Put each option into the calculator above and compare the cost per mg side by side.
Don't forget shipping and supplies
Bacteriostatic water, syringes, swabs, and shipping all add to what you really paid. Open the extra settings above and put them in, so your cost per mg shows the true total.
Where to buy Retatrutide

Retatrutide price per month at each weekly amount
Retatrutide is used once a week, and a month works out to 4.33 weeks. The milligram columns below never change. The dollar columns are just examples at $5 and $10 per mg. They are not real quoted prices, because retatrutide has no approved list price.
| Weekly amount | mg per month | mg per year | Monthly at $5/mg | Monthly at $10/mg |
|---|---|---|---|---|
1 mg | 4.3 mg | 52 mg | $22 | $43 |
2 mg | 8.7 mg | 104 mg | $44 | $87 |
4 mg | 17.3 mg | 208 mg | $87 | $173 |
6 mg | 26 mg | 312 mg | $130 | $260 |
8 mg | 34.7 mg | 416 mg | $174 | $347 |
12 mg | 52 mg | 624 mg | $260 | $520 |
Examples only. The per mg rates above are round numbers picked to be easy to read, not prices we quote or recommend. Enter your own vial price in the calculator to get your real numbers.
Retatrutide Cost Per Month & Per Year
Once you know your cost per mg, your monthly retatrutide cost is just that number times your weekly milligrams times 4.33 weeks.
A month is 4.33 weeks, not 4
Retatrutide is used once a week, and a month is a bit longer than four weeks. If you count four doses a month, you end up about 8% short over a year. This calculator divides 52 weeks by 12 months instead, so the monthly and yearly numbers match.
Your monthly cost goes up with the amount
You pay by the milligram, so doubling your weekly amount doubles your monthly retatrutide cost. Run the numbers again at each step of your plan instead of only pricing the amount you start with.
Check the yearly number too
A few dollars per mg looks tiny on one vial, but it can add up to hundreds of dollars over a year. That is why the calculator shows the yearly cost right next to the monthly one.
Frequently Asked Retatrutide Cost Questions
Plain answers on retatrutide pricing, cost per mg, and monthly cost. For research reference only. Not medical advice and not a price quote.
Planning a Research Budget Around Retatrutide
Cost per mg is only the start. Doses per vial, when to reorder, and how retatrutide stacks up against other GLP-1 compounds are what turn a price into a plan.
Know how long an order actually lasts
Doses per vial and weeks per order tell you when you will run out and need to order again. When you are planning a full research cycle, that is usually more useful than the price tag.
Compare against other GLP-1 compounds
You cannot compare cost per mg between two different compounds, because the same result takes a different number of milligrams. Use the semaglutide to tirzepatide conversion calculator to match up the amounts first, then price each one here.
No approved price exists yet
Retatrutide is still experimental. There is no FDA-approved list price, no pharmacy price, and no insurance coverage. Every price you see quoted comes from the research market, not from an official source.
