What retatrutide actually costs
Retatrutide is investigational, so there is no list price and no insurance. What people pay comes down to two things: the cost per mg of the vial they buy, and how much they inject each week. Because the dose climbs during titration, the first few months cost less than a flat monthly figure suggests, and a full course costs more than one month multiplied out. The calculator above works both out from the price you paid; the tables below show the pattern at a real tracked price.
Monthly cost by dose (example: $194 for a 30mg vial = $6.47/mg)
| Weekly dose | Per week | Per month | Per year |
|---|---|---|---|
| 1 mg | $6.47 | $28.02 | $336 |
| 2 mg | $12.93 | $56.04 | $673 |
| 4 mg | $25.87 | $112.09 | $1345 |
| 6 mg | $38.80 | $168.13 | $2018 |
| 8 mg | $51.73 | $224.18 | $2690 |
| 12 mg | $77.60 | $336.27 | $4035 |
Example figures only, at $194 for a 30mg vial. Larger vials usually cost less per mg, so your real number depends on the size you buy. Enter your own price above.
Why titration changes the total
The standard retatrutide ladder starts at 2mg/week and steps up every four weeks (2mg, then 4mg, 8mg, and 12mg), which is drawn from the Phase 2 protocol and Eli Lilly's TRIUMPH trials. Those early weeks use far less drug, so they cost far less. Reaching an 8mg maintenance dose the standard way means about $155 across the 8-week ramp, and roughly $2431 for a full first year at that example price. Many people settle at a moderate dose (4 to 8mg) rather than pushing to 12mg, which keeps the ongoing cost lower.
How your price compares to the market
Across tracked US research-peptide vendors, confirmed retatrutide pricing ranged from about $6.3/mg to $11.38/mg (captured April 2026). At 8mg/week that is roughly $218 to $395/month. Compounded retatrutide from a telehealth provider typically runs $200 to $500/month, and if it reaches the commercial market (projected 2027 to 2028) the list price is expected to land around $1,000 to $1,500/month before any savings program. The market check in the calculator places your own cost per mg on that range. It reads only the price you enter and does not quote, recommend, or endorse any vendor.
