10mg vial + 0.5mL BAC water = 10 units = 2mg — Amounts listed in the Dosify Me data: 2mg-12mg max, titrated up every 4 weeks — Frequency: weekly — Best taken: same day each week, any time
Informational only, not medical advice. Consult a licensed healthcare provider before starting or changing any protocol.
Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.
Vial sizes up to 60 mg are mixed to 20 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 5 mg | 0.25 mL | 20 mg/mL |
| 10 mg | 0.50 mL | 20 mg/mL |
| 15 mg | 0.75 mL | 20 mg/mL |
| 20 mg | 1.00 mL | 20 mg/mL |
| 30 mg | 1.50 mL | 20 mg/mL |
| 40 mg | 2.00 mL | 20 mg/mL |
| 50 mg | 2.50 mL | 20 mg/mL |
| 60 mg | 3.00 mL | 20 mg/mL |
| 100 mg* | 3.00 mL | 33.33 mg/mL |
| 120 mg* | 3.00 mL | 40 mg/mL |
* This size is conventionally mixed more concentrated rather than diluted further — fewer units per dose than smaller vials of this peptide.
On a standard 100-unit (1 mL) insulin syringe, for vials mixed to 20 mg/mL (sizes marked * are more concentrated and need fewer units):
| Dose | Syringe units |
|---|---|
| 2 mg | 10.0 units |
| 4 mg | 20.0 units |
| 6 mg | 30.0 units |
| 8 mg | 40.0 units |
| 10 mg | 50.0 units |
| 12 mg | 60.0 units |
Amounts listed in the Dosify Me data: 2000–12000 mcg. Frequency: weekly. Timing: same day each week, any time of day.
Listed titration schedule: weeks 1-4 2mg, weeks 5-8 4mg, weeks 9-12 6mg, weeks 13+ 8mg (standard protocol). Advanced/aggressive protocols escalate to 12mg by week 13+; these are listed schedules, not recommendations. Vial sizes up to 60mg reconstitute to 20mg/mL — 5 units always = 1mg (e.g. 60mg + 3mL BAC water, or 30mg + 1.5mL). The 100mg and 120mg options are capped at 3mL BAC water instead of diluted further, so they come out more concentrated (fewer units per dose) than smaller sizes.
Check one row of the table above: 2000 mcg is 2 mg; 2 mg ÷ 20 mg/mL = 0.1 mL; 0.1 mL × 100 = 10 units.

Like other GLP-1-class drugs, retatrutide's triple-receptor action slows digestion, which can change absorption of other oral medications, including thyroid medication (levothyroxine) — dose and timing may need adjustment. Combined with insulin or a sulfonylurea, the added blood-sugar-lowering effect can cause hypoglycemia — those doses often need to be reduced first. Talk to your prescribing doctor before combining.

At 20 mg/mL (the standard mix for vials up to 60 mg), 2 mg of Retatrutide is 10.0 units on a 100-unit insulin syringe (0.100 mL).
At 20 mg/mL (the standard mix for vials up to 60 mg), 4 mg of Retatrutide is 20.0 units on a 100-unit insulin syringe (0.200 mL).
At 20 mg/mL (the standard mix for vials up to 60 mg), 6 mg of Retatrutide is 30.0 units on a 100-unit insulin syringe (0.300 mL).
0.25 mL, which gives 20 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
0.50 mL, which gives 20 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
0.75 mL, which gives 20 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.
Weekly. Same day each week, any time of day Typical cycle: Often run continuously; tapering is done under guidance.
Yes. “reta” is the short name people use for Retatrutide in forums and search, and every figure on this page is for that same compound. The units, water and schedule above do not change with the spelling.
Dosify Me does this math for you. Pick the compound, your vial size and dose, and the app draws the exact syringe reading, keeps your schedule and reminders, and logs every dose — privately, on your phone.

Figures come from the Dosify Me compound database for Retatrutide: concentration is the vial amount ÷ the water volume, and syringe units are the volume in mL × 100 on a U-100 syringe.
