Static reference for the lyophilized 10mg and 40mg retatrutide vials supplied as peptide powder. Vial size, vial quantity, and total bacteriostatic water volume control the resulting concentration, draw volume, and total volume. For the live calculator with custom amounts, open the vial calculator.
| Vial size | BAC water | Concentration | U-100 units for 1mg |
|---|---|---|---|
| 10mg vial | 1mL | 10mg/mL | 10 units |
| 10mg vial | 2mL | 5mg/mL | 20 units |
| 10mg vial | 3mL | 3.33mg/mL | 30 units |
| 40mg vial | 1mL | 40mg/mL | 2.5 units |
| 40mg vial | 2mL | 20mg/mL | 5 units |
| 40mg vial | 3mL | 13.33mg/mL | 7.5 units |
Math: concentration mg/mL = vial mg ÷ bac water mL. On a U-100 insulin syringe (100 units = 1mL), units to draw for a target mg = (target mg ÷ concentration mg/mL) × 100. Accurate measurement matters because a small change in added water changes the concentration and draw volume for every calculation. For laboratory handling context, add bacteriostatic water slowly against the vial wall, then gently swirl or roll the vial; do not shake vigorously. See the bacteriostatic water guide for the 28-day discard window and storage notes.
This peptide calculator targets the four retatrutide pen formats supplied for in-vitro research: the 10mg pen (~0.033mg per click), the 20mg pen (~0.067mg per click), the 30mg pen (0.1mg per click), and the 40mg pen (~0.133mg per click). Each format holds 300 clicks — mg per click changes with the pen’s total concentration, so the click count for the same research amount differs between formats. Once your format is chosen, you can compare all UAE retatrutide formats, buy Retatrutide 30mg pen in Dubai as the flagship option, or compare the Retatrutide 20mg pen and the Retatrutide 10mg vial.
Enter a target research amount in mg and the calculator returns the exact click count for the selected pen, plus dial turns and estimated pen duration. When the material is supplied as a lyophilized vial instead of a pen, the workflow changes: the vial calculator first determines the bacteriostatic water volume, mg/mL concentration, and draw volume before any syringe-unit lookup is useful.
Retatrutide (LY-3437943) is a triple agonist that engages the GLP-1, GIP (glucose-dependent insulinotropic polypeptide), and glucagon receptors in the published Phase 2 and Phase 3 research literature. The calculator does not model receptor pharmacology — it handles the mg-to-click conversion math so research protocol planning stays within the dial-cap and pen-volume limits of the selected format.
Use the clicks chart for a static lookup table, the dosage guide for the TRIUMPH Phase 3 titration schedule, and the vial calculator when working with lyophilized 10mg or 40mg vials instead of prefilled pens.
Batch proof is published through Janoshik COAs, while pen-click math remains based on the 300-click pen mechanism. See batch RETP002 and the full lab results for the retatrutide 10mg vial, 20mg pen, 40mg vial batch line, and 30mg Remedium pen.

Whole-pen counts using the TRIUMPH-1 retatrutide titration: week 1 starts at 2mg, week 4 at 4mg, week 8 at 8mg, week 12 at 12mg, then 12mg weekly for maintenance. Totals: 8-week course ~26mg, 16-week course ~80mg, 24-week course ~176mg. Counts round up to the next whole pen because pens are not split between protocols. These are published clinical-trial schedule references for research math, not human or veterinary use instructions.
| Pen format | 8-week course (~26mg) | 16-week course (~80mg) | 24-week course (~176mg) |
|---|---|---|---|
| 10mg pen | 3 pens | 8 pens | 18 pens |
| 20mg pen | 2 pens | 4 pens | 9 pens |
| 30mg pen | 1 pen | 3 pens | 6 pens |
| 40mg pen | 1 pen | 2 pens | 5 pens |
How many clicks on a retatrutide pen?
For the 30mg retatrutide pen, each click equals 0.1mg, so 1mg = 10 clicks, 2mg = 20 clicks, 4mg = 40 clicks, 6mg = 60 clicks, 8mg = 80 clicks, and 12mg = 120 clicks. The 30mg pen contains 300 clicks total and the dial caps at 60 clicks per dispensing cycle. Other pen strengths use different mg-per-click ratios, which this calculator applies automatically.
How many clicks is 1mg retatrutide?
On the 30mg pen, 1mg = 10 clicks (0.1mg per click). On the 20mg pen: 15 clicks; 10mg pen: 30 clicks; 40mg pen: 8 clicks. Each fits in a single dial setting.
How many clicks is 2mg retatrutide?
On the 30mg pen, 2mg = 20 clicks. On the 20mg pen: 30 clicks; 10mg pen: 60 clicks (dial cap); 40mg pen: 15 clicks. 2mg is the published Phase 3 starting reference and stays under the 30mg pen’s 60-click per-cycle cap.
How many clicks is 2.5mg retatrutide?
On the 30mg pen, 2.5mg = 25 clicks in one dial turn. On the 20mg pen: 38 clicks; 10mg pen: 75 clicks (dial cap); 40mg pen: 19 clicks.
What is the retatrutide dosage calculator formula?
The formula is mg per click = total pen mg / 300 clicks, then clicks needed = target research mg / mg per click. For example, the 30mg pen gives 30mg / 300 = 0.1mg per click, so 4mg = 40 clicks. The calculator rounds to whole clicks and checks the dial cap.
Is this calculator a medical dosing tool?
No. This calculator is for research planning math only. It does not provide human-use dosing instructions, injection guidance, treatment advice, side-effect management, or personalized dose changes. Remy Peptides supplies research-use-only materials for in-vitro laboratory research, not human or veterinary use.
Can the same target mg be used across 10mg, 20mg, 30mg, and 40mg pens?
The same target research amount can be entered for any pen format, but the click count changes because mg per click changes. A 4mg target equals 120 clicks on the 10mg pen, 60 clicks on the 20mg pen, 40 clicks on the 30mg pen, and 30 clicks on the 40mg pen.
What does this retatrutide planning tool calculate?
It converts a target research amount into clicks for the selected pen format (10mg, 20mg, 30mg, or 40mg), estimates how many scheduled calculations the plan includes, and shows how many pens the protocol will consume over time. It is planning math only, not medical guidance.
How many clicks are in the 30mg retatrutide pen?
The 30mg pen contains 300 clicks total, with each click delivering 0.1mg of retatrutide. Dial caps at 60 clicks (6mg) per dispensing cycle.
How many clicks are in the 20mg retatrutide pen?
The 20mg pen contains 300 clicks total, with each click delivering ~0.067mg of retatrutide. Dial caps at 75 clicks (5mg) per dispensing cycle.
How many clicks are in the 10mg retatrutide pen?
The 10mg pen contains 300 clicks total, with each click delivering 0.033mg of retatrutide. Dial caps at 75 clicks (2.5mg) per dispensing cycle.
How many clicks are in the 40mg retatrutide pen?
The 40mg pen contains 300 clicks total, with each click delivering ~0.133mg of retatrutide. Dial caps at 75 clicks (10mg) per dispensing cycle.
When does a result need to be split?
The 30mg pen dial tops out at 60 clicks (6mg) per dispensing cycle; the 10mg, 20mg, and 40mg pens dial up to 75 clicks per dispensing cycle. Targets above the dial cap need more than one dial turn.
Can this tool tell me how many pens I need for a multi-week protocol?
Yes. The calculator combines the target research amount, dosing frequency, and protocol duration to estimate how many full pens a plan will require. The estimate assumes consistent dosing and does not subtract priming losses, pauses, or protocol changes.
What is the difference between this planning tool and the clicks chart?
The clicks chart is the quick lookup page for direct mg-to-click conversions. This planning tool also estimates total doses, pens needed, and protocol duration.
Does this replace the full dosage guide?
No. This page handles the math. The dosage guide covers the broader Phase 3 titration schedule, escalation pace, and target amounts used in published retatrutide protocols.
Where do I check source documentation and pen specs?
Open the COA library for certificate files and the pen guide for format mechanics. For broader regional context, see peptides in the UAE.
What does 0.1mg per click mean on the 30mg retatrutide pen?
0.1mg per click means each dial increment dispenses 0.1mg of retatrutide from the 30mg pen. Ten clicks = 1mg, 40 clicks = 4mg, 60 clicks = 6mg (the per-cycle dial cap). The 30mg pen holds 300 clicks total because 30mg / 0.1mg per click = 300.
Why does mg per click differ across the 10mg, 20mg, 30mg, and 40mg pens?
All four pen formats hold 300 clicks. The mg-per-click ratio scales with the total mg loaded into the pen: 10mg / 300 = 0.033mg per click, 20mg / 300 ≈ 0.067mg per click, 30mg / 300 = 0.1mg per click, and 40mg / 300 ≈ 0.133mg per click. The retatrutide dosage calculator applies the correct ratio automatically when you pick a pen format.
How do I plan a multi-week research protocol with this calculator?
Switch to the Protocol Planner tab, set the target research amount (mg per calculation), dosing frequency, and total protocol length in weeks. The calculator returns clicks per dose, scheduled doses, pens consumed, and the per-pen duration. The output assumes consistent dosing and does not subtract priming losses or planned pauses.
What is the difference between the pen calculator and the vial calculator?
The pen calculator converts mg to clicks for the four prefilled retatrutide research pens. The vial calculator handles the reconstitution math for lyophilized 10mg and 40mg vials — vial size, vial quantity, bacteriostatic water volume, mg per mL concentration, draw volume, and U-100 insulin syringe unit conversion. Use the pen calculator for pen formats, the vial calculator for vials.
How many retatrutide pens for an 8-week, 16-week, or 24-week research course?
Using the TRIUMPH-1 titration (2mg → 4mg → 8mg → 12mg, then 12mg weekly maintenance), an 8-week course totals ~26mg, a 16-week course ~80mg, and a 24-week course ~176mg. The pens-per-protocol table above gives whole-pen counts for each format: the 30mg pen covers an 8-week course in 1 pen, a 16-week course in 3 pens, and a 24-week course in 6 pens. The 40mg pen uses 1 / 2 / 5 pens across the same three windows.
How do I reconstitute a retatrutide vial with bacteriostatic water?
Add bacteriostatic water slowly down the inside wall of the lyophilized 10mg or 40mg vial, then gently swirl or roll the vial until the peptide powder dissolves into a clear solution. The reconstitution reference table above shows how 1mL, 2mL, and 3mL bac water volumes change concentration and U-100 insulin syringe units. For the full step-by-step protocol, sterility notes, and the 28-day discard window, open the bacteriostatic water guide.
How many clicks is 2mg on the 40mg retatrutide pen?
On the 40mg retatrutide pen, 2mg = 15 clicks. Each click delivers about 0.133mg, so 2mg divided by 0.133mg rounds to 15 clicks, which sits in one dial setting under the 75-click dispensing cap. On the same 40mg pen, 1mg is about 8 clicks, 4mg about 30 clicks, 8mg about 60 clicks, and 10mg is 75 clicks (the dial cap, equal to 10mg). The calculator above applies this 0.133mg-per-click ratio automatically when you select the 40mg pen.
Working with a lyophilized vial instead of a pen?
Lyophilized 10mg and 40mg retatrutide vials need reconstitution with bacteriostatic water before in-vitro research use. The vial calculator returns the resulting mg per mL concentration, draw volume in U-100 insulin syringe units, and a reverse unit lookup once you set the vial quantity and bac water volume. The pen formats skip the reconstitution step — the dial does the volume math for you.
