Retatrutide Cost: What It Actually Comes To
Retatrutide is sold by the vial, so the headline price tells you less than the cost per milligram does. A 10mg vial and a 50mg vial differ by a factor of five in material but only 2.5x in price. This page breaks the cost down both ways, current as of September 2026.
These are prices for retatrutide supplied for laboratory research use, not for a prescription product. Retatrutide has no approved label and is not available by prescription — see retatrutide dosing and regulatory status.
Retatrutide price per vial
| Vial size | Price | Cost per mg |
|---|---|---|
| 10mg | $69 | $6.90 |
| 15mg | $90 | $6.00 |
| 20mg | $100 | $5.00 |
| 30mg | $128 | $4.27 |
| 40mg | $155 | $3.88 |
| 50mg | $175 | $3.50 |
Cost per milligram falls by roughly half moving from the 10mg vial to the 50mg vial. That is the single biggest lever on what retatrutide costs.
Retatrutide cost in bulk
Wholesale kits of 10 vials are priced 20% below the equivalent single-vial cost, which pushes the cost per milligram down further:
| Kit | Kit price | Per vial | Cost per mg |
|---|---|---|---|
| 10 × 5mg | $340 | $34.00 | $6.80 |
| 10 × 10mg | $552 | $55.20 | $5.52 |
| 10 × 20mg | $800 | $80.00 | $4.00 |
| 10 × 30mg | $1,020 | $102.00 | $3.40 |
| 10 × 50mg | $1,400 | $140.00 | $2.80 |
| 10 × 60mg | $1,520 | $152.00 | $2.53 |
At the bottom of that table retatrutide costs $2.53 per milligram, against $6.90 for a single 10mg vial — a 63% difference for the identical compound. Full range on the bulk retatrutide listing.
Retatrutide cost per month
Because material is priced per milligram, monthly cost depends entirely on how much is used. At the dose levels studied in the Phase 3 TRIUMPH trials — 4mg, 9mg and 12mg weekly — a four-week period represents 16mg, 36mg and 48mg of material respectively.
At the single-vial rate for a 50mg vial ($3.50/mg) that is roughly $56, $126 and $168 of material per four weeks. At the bulk 60mg rate ($2.53/mg) it falls to roughly $40, $91 and $121. These are material costs only, for reference; they are not a recommendation to use any quantity.
How retatrutide compares on cost
Retatrutide is the most expensive of the three major GLP-1 research compounds per milligram, which reflects both its triple-agonist synthesis and tighter supply:
| Compound | 10mg vial | Cost per mg | Receptor targets |
|---|---|---|---|
| Semaglutide | $35 | $3.50 | GLP-1 |
| Tirzepatide | $44 | $4.40 | GLP-1 + GIP |
| Retatrutide | $69 | $6.90 | GLP-1 + GIP + glucagon |
Full cost breakdowns for the other two compounds: semaglutide cost and tirzepatide cost.

What drives the price
- Vial size. The largest single lever — cost per mg roughly halves from 10mg to 50mg.
- Order quantity. Wholesale kits of 10 are priced 20% under the single-vial rate.
- Supply. Retatrutide supply is tighter than semaglutide or tirzepatide, and pricing across the category moves with it.
- Testing. Every lot here is HPLC and mass-spectrometry verified before release, which is a real cost and the thing to check before comparing any two quoted prices.
Retatrutide Cost — Frequently Asked Questions
How much does retatrutide cost?
From $69 for a 10mg vial up to $175 for a 50mg vial, which works out to $6.90 down to $3.50 per milligram. Wholesale kits of 10 vials bring it as low as $2.53 per milligram.
What is the cheapest way to buy retatrutide?
Cost per milligram falls with both vial size and order quantity, so the lowest unit cost is a wholesale kit of the largest vial size — currently $2.53 per milligram.
Why does retatrutide cost more than semaglutide or tirzepatide?
Retatrutide is a triple agonist with a more involved synthesis, and supply is tighter. Per milligram it runs roughly twice semaglutide and about 57% above tirzepatide.
Is retatrutide covered by insurance?
No. Retatrutide is not FDA approved and has no approved label, so it is not a prescription product and is not covered by insurance. Material supplied here is for laboratory research use only.
