01

What is Liraglutide?

Plain language first. The technical label stays, but it never stands alone.

Overview

Liraglutide is a GLP-1 receptor agonist, the same hormone-copying approach as semaglutide but shorter-acting, so it is taken daily. In plain terms: it turns up your fullness signal to curb appetite and steady blood sugar. It is the drug in Saxenda and Victoza.

What it's used for

A daily version of the same appetite-lowering approach as Ozempic-style drugs, used for weight loss and blood sugar. It is older and a bit milder than the weekly options.

02

How does Liraglutide work?

What it does in the body, and where.

Liraglutide works on the same receptor as semaglutide. The difference is how long it lasts, which is why it is a daily injection rather than a weekly one.

  1. 01
    It docks at the GLP-1 receptor
    Same fullness signal, same slowed stomach emptying, same effect on blood sugar after eating.
  2. 02
    It clears from your body within a day
    The fatty-acid anchor that keeps it circulating is shorter than semaglutide's, so the effect fades and has to be renewed daily.
  3. 03
    Daily dosing changes the experience, not the mechanism
    Some people tolerate a smaller daily dose better than one large weekly one; others find the injection schedule harder to keep.
Receptors
HITSGLP-11

Acts on one receptor.

03

What else is it used for?

Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

  • Lowering the risk of heart attack, stroke, and heart-related death in adults with type 2 diabetes who already have heart diseaseFDA-approved
04

How much, and do you cycle it?

The range, and whether you take breaks.

0.6 up to 3 mg per day (start low, increase slowly), daily. Not cycledFDA label

A daily drug taken continuously. Weight returned after withdrawal in the trials.

How do I dose and price it?

Enter your vial and your dose. Pick a mix. We show the draw and the cost.

The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

How do you store it?

Before mixing, and after.

Fridge before first use. Room temperature is fine once in use.

Sealed pens live in the fridge. Once you start a pen it can stay at room temperature for the in-use window on the label (often about 4 to 6 weeks depending on the product). Keep it out of light, do not freeze it, and toss it if it has been frozen or left hot.

07

What are the side effects and cautions?

Known cautions and warnings for this compound.

22 July 2026In January 2026 the FDA asked that the warning about suicidal thoughts and behaviour be removed from the obesity versions of this drug family after a review found no increased risk. Labels were updated in February 2026.

Who should avoid it

Check these before anything else.
  • A personal or family history of medullary thyroid cancer, or the genetic condition MEN 2
  • Pregnancy, or trying to become pregnant

  • Signs of an allergic reaction

Common effects

Expected, and usually mild.
  • Nausea and vomiting, especially early on
  • Diarrhea and constipation

Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.

What these words mean

Show glossary +
Titrate
Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
Subcutaneous
An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
Intramuscular (IM)
An injection into a muscle, using a longer needle.
Reconstitution
Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
Bacteriostatic water
Sterile water with a tiny amount of preservative, used to mix powdered peptides.
Concentration
How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
Units (on the syringe)
The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
mcg and mg
Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
GLP-1
A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
Growth hormone secretagogue
A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
Half-life
How long a compound stays active in your body. A longer half-life means you inject less often.
Peptide vs small molecule
A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
Research only
No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
Investigational
Still being tested in clinical trials and not yet approved or legally sold for general use.
Banned in drug-tested sport
Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
