Liraglutide dosage chart: how many units on the syringe

Units measure volume, not milligrams

An insulin syringe is graduated for insulin, not for peptides. On a U-100 syringe, 100 marks span the full 1 mL barrel, so each mark is a fixed small fraction of a millilitre. Nothing on the barrel knows what is inside it.

That is why a Liraglutide dose cannot be read off the syringe until you know two things: how much peptide was in the vial, and how much bacteriostatic water you added. Those two figures give the concentration in mg per mL. Dividing the target dose by the concentration gives the volume to draw, and the volume converts directly to marks.

The table on this page runs that arithmetic for a 10 mg vial across 1, 2 and 3 mL of water, at the four dose amounts that appear in listings: 0.6, 1.2, 1.8 and 3 mg.

Three things to notice in the table

First, the unit count for a fixed dose rises as water rises. A 0.6 mg dose is 6 units at 1 mL, 12 units at 2 mL, 18 units at 3 mL. More water means a weaker solution, so more volume carries the same milligrams. Adding water does not change how much peptide leaves the vial per dose.

Second, the smallest doses in the most concentrated mix land on very few marks. At 10 mg/mL, 0.6 mg is 6 units. Reading 6 marks accurately is harder than reading 18, and a one-mark error is a larger share of a small draw. Diluting further spreads the same dose over more of the barrel, which is the practical argument for 2 or 3 mL.

Third, the far end of the table runs long. A 3 mg dose from a 10 mg vial in 3 mL comes to 90 units, which occupies most of a U-100 barrel. Some syringes sold as insulin syringes have a shorter barrel with fewer marks. Check that your syringe can hold the volume the table gives before you reconstitute, because the water volume is fixed once it is in the vial.

The 5 mg vial

Liraglutide is also sold in a 5 mg vial. Half the peptide in the same water gives half the concentration, so the numbers shift. A 5 mg vial reconstituted with 1 mL sits at 5 mg/mL, the same concentration the table shows for a 10 mg vial in 2 mL, and the unit counts in that column apply unchanged.

The useful habit is to stop thinking in vial sizes and think in mg/mL. Once you know the concentration, the vial that produced it is irrelevant to the arithmetic. Two vials of different sizes at the same concentration draw identical units for identical doses.

A smaller vial also means fewer doses per vial at any given dose size. This page does not compute how many doses a vial yields.

What this page does not answer

We hold no reliable human pharmacokinetic data for Liraglutide. This site therefore makes no statement about its half life, how long it takes to clear, how it accumulates with repeated use, or how often it would be given. The arithmetic above concerns concentration and volume and nothing else.

The dose amounts listed here are the ones that appear in vendor listings. Their presence in the table is not a recommendation. Nothing on this page tells you which dose to use, what to expect from it, what side effects it produces, or whether it is safe or effective for any purpose. DoseGraph has no medical review process and cannot answer clinical questions. Those belong to a clinician who can see your situation.

Regulatory status is worth stating plainly: Liraglutide is approved by a regulator for human use in at least one market. That says something about the molecule and nothing about the contents of a research vial, which is not the approved product and carries no verified identity, purity or concentration.

Where the arithmetic goes wrong in practice

The most common failure is a mismatch between the water you intended to add and the water actually in the vial. If a syringe is filled to the wrong mark during reconstitution, every dose drawn afterward is off by the same proportion, and the error is invisible. Reconstitute with a syringe you can read, and confirm the mark before you push.

The second failure is switching syringe types mid-vial. A U-100 syringe and a U-40 syringe both have marks called units, and they mean different volumes. Every number in the table assumes U-100. Read the barrel, not the box.

The third is arithmetic drift after a partial top-up. Adding more water to a vial already in use changes the concentration and invalidates the unit count you have been using. If the volume changes, the conversion has to be redone from the new total.

What we do not know

We hold no reliable human pharmacokinetic data for Liraglutide, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

How many units is 1.2 mg of Liraglutide?

It depends entirely on the concentration. From a 10 mg vial in 1 mL, 1.2 mg is 12 units on a U-100 syringe. From the same vial in 2 mL it is 24 units, and in 3 mL it is 36 units. The milligrams are identical in all three cases.

Does adding more bacteriostatic water reduce the dose?

No. Water changes the concentration, so the same milligrams occupy more volume and more syringe marks. The peptide leaving the vial per dose is unchanged. That is why the unit count triples between 1 mL and 3 mL while the mg figure stays put.

How much water should I add to a Liraglutide vial?

There is no correct answer, only trade-offs the table makes visible. Less water gives fewer marks per dose and a shorter draw. More water spreads the dose over more marks, which is easier to read, but pushes large doses toward the top of the barrel, as with 3 mg in 3 mL at 90 units.

What is the half life of Liraglutide?

We do not publish one. This site holds no reliable human pharmacokinetic data for Liraglutide, so it makes no claim about half life, clearance or accumulation. Every figure on this page is a concentration and volume calculation.

Can I use a U-40 syringe instead?

The unit counts in the table assume a U-100 syringe, where 100 marks span the 1 mL barrel. A U-40 syringe uses different mark spacing, so the numbers will not transfer. Confirm which scale is printed on the barrel before drawing anything.

Is this dosing advice?

No. The doses shown are the amounts that appear in listings, converted to syringe units. Nothing here says which dose to take, whether it works, or whether it is safe. This page has no medical review and no clinical position.
