How Many Clicks Retatrutide Pen? Click Calculator: Clicks to mg

How many clicks is 1 mg on a retatrutide pen? A retatrutide pen click calculator converts pen dial clicks into milligrams of listed material on documented 300-click research pens: about 30 clicks per 1 mg on the 10mg pen, 15 on the 20mg, 10 on the 30mg, and about 7.5 on the 40mg. Listed material equals clicks × total labelled mg ÷ 300: configuration math for laboratory planning, not personal dosing guidance.

Quick answer: clicks per 1mg of listed material

One-milligram research reference by documented pen format
Pen format	Listed material per click	Clicks representing 1mg	Batch evidence
10mg / 300 clicks	~0.033 mg	~30 clicks	RET-20-V-2604-001 (supplier-mapped from 20mg lyophilised sample)
20mg / 300 clicks	~0.067 mg	15 clicks	RET-20-C-2604-001
30mg / 300 clicks	0.1 mg	10 clicks	RETP002
40mg / 300 clicks	~0.133 mg	~7.5 clicks	RET-20-V-2604-001 (supplier-mapped from 20mg lyophilised sample)

These figures describe the listed configuration of each documented research pen. They do not establish delivered volume, device condition, administration instructions, or suitability for human or veterinary use.

Before comparing clicks, separate the labelled amount, documented total clicks and fill volume:

What each pen specification means for this listed-material calculator
Specification	What it is and how this page uses it
Labelled amount (mg)	The material amount printed for the selected pen format. Used as the numerator: labelled amount ÷ documented total clicks = listed material per click.
Documented total clicks	300 clicks applies only to the ProPeptide 10mg, 20mg and 40mg pens and the Remedium Research 30mg FlexiPen listed here. Used as the denominator for these four configurations only; it is not a universal pen scale.
Fill volume (mL)	The liquid volume in the pen. The four documented pens list 3 mL on their product pages. Not used: the converter does not calculate or infer volume from labelled milligrams.

Match the labelled format to its ProPeptide 10mg, 20mg or 40mg product specification, or the Remedium Research 30mg FlexiPen specification. Click counts for other pen formats are not published here; use the supplied instructions or package label.

For batch evidence, follow the batch verification walkthrough and compare the report sample and batch with the product label. A published report does not confirm the lot you will receive.

Retatrutide pen clicks chart and starting dose: 0.5mg to 5mg by pen size

Clicks for each listed-material amount on the four documented 300-click pens
Listed material	10mg pen	20mg pen	30mg pen	40mg pen
0.5mg	15	≈8 (7.5)	5	≈4 (3.75)
1mg	30	15	10	≈8 (7.5)
1.5mg	45	≈23 (22.5)	15	≈11 (11.25)
2mg	60	30	20	15
2.5mg	75	≈38 (37.5)	25	≈19 (18.75)
3mg	90*	45	30	≈23 (22.5)
4mg	120*	60	40	30
5mg	150*	75	50	≈38 (37.5)

The dial moves in whole clicks, so the chart shows clicks rounded to the nearest whole click (≈), with the exact value in brackets, the same rounding the pen planner uses, which means the delivered amount may land slightly above or below the exact listed-material amount after rounding. *More than one dial setting: the 10mg, 20mg and 40mg pens cap at 75 clicks per dial and the 30mg pen at 60; the pen planner shows dial limits and pens needed.

How many clicks on a 10mg, 20mg, 30mg or 40mg retatrutide pen?

Each documented pen on this page holds 300 clicks. What changes is the listed material behind each click, so the same milligram amount needs a different click count on each pen size.

Retatrutide 10mg pen clicks

About 0.033mg per click. 1mg is 30 clicks, 2mg is 60 clicks and 2.5mg is 75 clicks, the full single dial. 3mg (90 clicks) and 4mg (120 clicks) go past the 75-click dial cap, so they take more than one dial setting and may need to be split across settings because the single-setting maximum is capped.

Retatrutide 20mg pen clicks

About 0.067mg per click. 1mg is 15 clicks, 2mg is 30 clicks, 2.5mg is about 38 clicks, 3mg is 45 clicks and 4mg is 60 clicks. All of them fit under the 75-click dial cap, and 75 clicks on this pen is 5mg.

Retatrutide 30mg pen clicks

0.1mg per click, the simplest pen to count. 1mg is 10 clicks, 2mg is 20, 2.5mg is 25, 3mg is 30, 4mg is 40 and 5mg is 50. The dial on this pen stops at 60 clicks, which is 6mg.

Retatrutide 40mg pen clicks

About 0.133mg per click. 1mg is 7.5 clicks, so 7 or 8 whole clicks. 2mg is 15 clicks, 2.5mg is about 19, 3mg is about 23, 4mg is 30 and 5mg is about 38, all under the 75-click dial cap. Other brands' 40mg pens are not covered here, so check their own label for the click count.

Configuration math for laboratory planning, not personal dosing guidance. To see how many pens a schedule uses or how long one pen lasts, use the retatrutide pen calculator.

How many mg is 10, 15, 20, 25 or 30 clicks of retatrutide?

Listed material, in mg, for a given click count on each documented 300-click pen
Clicks	10mg pen	20mg pen	30mg pen	40mg pen
10 clicks	~0.33	~0.67	1	~1.33
15 clicks	0.5	1	1.5	2
20 clicks	~0.67	~1.33	2	~2.67
25 clicks	~0.83	~1.67	2.5	~3.33
30 clicks	1	2	3	4

Some research pens have a built-in safety cap on how far a single turn can adjust, which gives more precise click control. Research hardware may also need to prime before use, so users can confirm flow before injection, and on most pens a single setting is capped so the dial cannot exceed the device’s per-turn limit.

For verifiable reta research material, see the COA library: RET-20-C-2604-001 (20mg pen), RETP002 (30mg pen) and RET-20-V-2604-001, a 20mg lyophilised sample supplier-mapped to the 10mg and 40mg pen formats. Its 99.741% HPLC result is for that sample. For how pre-filled pens compare with lyophilized vials on stability, heat and cost per mg, see peptide pen vs vial.

Supported formula and limits

Formula: listed material per click = labelled format amount ÷ 300; selected-click total = click count × listed material per click. The calculation assumes the specific 300-click configurations documented above. Liquid volume can only be calculated once the medication concentration is known. To find volume, divide the target dose by that value so you can read the amount in mL, then convert it to units on an insulin syringe when relevant. It does not verify fill accuracy, delivered volume, device condition, or any unlisted format, and it does not confirm whether any unapproved product contains the correct dose.

The nominal device scale is a specification check only. Current lot and device documentation, together with an authorised institutional laboratory SOP, control dispensing calibration, compatible accessories, handling and disposal. Users should also set device assumptions and accessory selection in line with that SOP.

Reading published trial data

ClinicalTrials.gov records, such as the TRIUMPH-1 Phase 3 record (NCT05929066), and peer-reviewed publications, such as the Phase 2 trial in the New England Journal of Medicine (2023), provide trial information about study arms run by trial teams under their own protocols. In those settings, retatrutide was studied as a once-weekly injection under trial protocols, and dosing protocols are individualized for patients. They may be determined by body weight, medical history, and the obesity-related goals being studied, while trial teams also study different groups of people and, where relevant, adjust treatment over time in gradual steps. Trial teams may also consult age and kidney function when setting dose levels and tracking weight loss response. Incorrect dosing can reduce benefits or increase side effects, so trial teams monitor progress over time and track adjustments during treatment. Common gastrointestinal side effects are similar to those seen with other GLP-1-related medicines. They are evidence about investigational clinical development, not instructions for a research product, so this converter does not map trial arms onto clicks.

This content is not medical advice: for any healthcare decision, consult a qualified clinician. For current regulatory status, see is retatrutide approved? and the retatrutide UAE guide. Longer-term cardiovascular outcomes research is ongoing. Seller listings often label retatrutide “GLP-3”; the GLP-3 retatrutide naming guide explains the nickname.

Clicks-to-mg frequently asked questions

How many clicks is 1mg on a retatrutide 10mg, 20mg, 30mg or 40mg pen?

It depends on the labelled format: approximately 30 clicks for the 10mg pen, 15 clicks for the 20mg pen, 10 clicks for the 30mg pen, and about 7.5 clicks for the 40mg pen (the dial moves in whole clicks: 7 clicks is about 0.93mg and 8 clicks about 1.07mg). These are listed-material configuration references for laboratory planning, not personal dosing guidance.

How many clicks is 2mg on a 20mg retatrutide pen?

30 clicks. The 20mg pen spreads 20mg over 300 clicks, about 0.067mg per click, so 2mg of listed material is 30 clicks. On the other documented formats 2mg is 60 clicks on the 10mg pen, 20 clicks on the 30mg pen and 15 clicks on the 40mg pen. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 2.5mg on a 30mg retatrutide pen?

25 clicks. The 30mg pen lists 0.1mg per click, so 2.5mg of listed material is 25 clicks. On the 20mg pen 2.5mg works out to 37.5 clicks (about 38), on the 40mg pen to 18.75 clicks (about 19), and on the 10mg pen to 75 clicks, the full single-dial maximum. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 4mg retatrutide?

30 clicks on the 40mg pen, 40 clicks on the 30mg pen and 60 clicks on the 20mg pen, each in one dial setting. On the 10mg pen 4mg is 120 clicks, which is past the 75-click dial cap, so it takes more than one setting. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 3mg on a reta pen?

30 clicks on the 30mg pen, 45 clicks on the 20mg pen and 22.5 clicks on the 40mg pen, so 22 or 23 whole clicks. On the 10mg pen 3mg is 90 clicks, past the 75-click dial cap, so it needs more than one setting. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 1.5mg retatrutide?

15 clicks on the 30mg pen, 22.5 clicks on the 20mg pen (about 23), 11.25 clicks on the 40mg pen (about 11) and 45 clicks on the 10mg pen. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 5mg on a 40mg retatrutide pen?

37.5 clicks, so 37 or 38 whole clicks (about 4.93mg or 5.07mg). That fits in one setting under the 40mg pen’s 75-click dial cap. On the 30mg pen 5mg is 50 clicks, and on the 20mg pen it is 75 clicks, the full dial. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks is 2mg or 2.5mg on a 40mg retatrutide pen?

2mg is 15 clicks. 2.5mg is 18.75 clicks, so 18 or 19 whole clicks; both aim at the same dose target, with the exact amount differing slightly because the dial moves in whole-click increments (about 2.4mg or 2.53mg). The 40mg pen lists about 0.133mg per click (40mg ÷ 300 clicks), and both amounts fit in one setting under its 75-click dial cap. On the 30mg pen the same amounts are 20 and 25 clicks. Configuration math for laboratory planning, not personal dosing guidance.

How many mg is 20 clicks on a retatrutide pen?

It depends on the pen format: 20 clicks is about 0.67mg on the 10mg pen, about 1.33mg on the 20mg pen, 2mg on the 30mg pen and about 2.67mg on the 40mg pen. Each documented pen holds 300 clicks, so one click is the labelled amount divided by 300. Configuration math for laboratory planning, not personal dosing guidance.

How many mg is 10, 15 or 30 clicks of retatrutide?

On the 10mg, 20mg, 30mg and 40mg pens, 10 clicks is about 0.33mg, 0.67mg, 1mg and 1.33mg. 15 clicks is 0.5mg, 1mg, 1.5mg and 2mg. 30 clicks is 1mg, 2mg, 3mg and 4mg. Configuration math for laboratory planning, not personal dosing guidance.

How many clicks are in a retatrutide pen?

Each documented pen here holds 300 clicks: the ProPeptide 10mg, 20mg and 40mg pens and the Remedium Research 30mg FlexiPen. Each click advances the internal plunger by a fixed increment. So a 40mg pen holds 300 clicks of about 0.133mg each. The dial stops at 75 clicks per setting on the 10mg, 20mg and 40mg pens and at 60 clicks on the 30mg pen, but that per-setting cap is separate from the total 300 clicks in the cartridge. The pen planner shows how long one pen lasts on a given schedule.

Do all reta research pens use the same clicks-to-mg value?

No. The value is format-specific. For the documented 300-click configurations, listed material per click equals the labelled format amount divided by 300.

How do insulin syringes and insulin syringe measurements relate to reconstituted vial math?

Standard U-100 insulin syringe measure 100 units per 1 mL. With a reconstituted vial, that scale converts liquid volume into a syringe reading for planning; if you add different amounts of BAC water, the concentration changes, so the dose can map to different unit markings.

Which reta pen formats have batch-specific COA evidence here?

The 20mg format maps to batch RET-20-C-2604-001, the 30mg format to RETP002, and the 10mg and 40mg pens are supplier-mapped to RET-20-V-2604-001, a 20mg lyophilised sample with 99.741% HPLC purity.

Does this page answer frequently asked questions on vial conversion?

Yes, with one worked example: a 10 mg vial—if you add 2 mL of BAC water—has a concentration of 5 mg/mL, so a 2 mg retatrutide dose draws to 0.4 mL, or 40 units on a U-100 syringe. Retatrutide vials commonly range from 5 mg to 40 mg, and both the vial size and the bacteriostatic water volume change the concentration. For repeat lab planning, the calculator can help log conversion details alongside your vial setup. You can enter vial strength, liquid volume, and dose details into the calculator to convert the result into mL and U-100 units.

Does this converter turn clinical-trial doses into pen clicks?

No. ClinicalTrials.gov records and peer-reviewed retatrutide publications describe study arms run by trial teams under their own protocols. They are evidence about investigational clinical development, not instructions for a research product, so trial arms are not converted into clicks, quantities or schedules here.

Is the retatrutide research pen approved for human use?

No. Available data are still limited, and it is not yet established as safe because retatrutide remains investigational. Retatrutide remains investigational, and Remy Research supplies the material for in-vitro laboratory research only, not for human or veterinary use. For approved options, speak with a qualified healthcare professional rather than using unapproved products sold online.

Need batch context for the number?

Published Janoshik reports cover the 20mg pen (RET-20-C-2604-001) and the 30mg pen (RETP002). The supplier maps the 10mg and 40mg formats to RET-20-V-2604-001, a 20mg lyophilised sample. Its 99.741% HPLC result applies to that sample. Open the applicable batch record to check the task number, verification key and analytical panel behind the number. Lilly said in July it plans to submit a BLA in the first quarter of 2027, but that is not approval. This page checks research-reference math only. It does not substitute for professional medical advice, diagnosis, or treatment. Before people make health decisions or change any dose, consult a doctor or other healthcare professional.
