What is Zovaglutide (ZT-002)?
Plain language first. The technical label stays, but it never stands alone.Overview
Zovaglutide is a long-acting GLP-1 receptor agonist. In plain terms: it gives the usual GLP-1 appetite control but lasts long enough to inject just once a month. It is still experimental.
What it's used for
An experimental once-a-month weight-loss shot, with about 14% loss in early testing.
How does Zovaglutide (ZT-002) work?
What it does in the body, and where.Zovaglutide is a GLP-1 agonist engineered to last long enough for monthly dosing.
- 01Standard GLP-1 receptor activationNothing unusual about the mechanism itself.
- 02The difference is how long it circulatesLong enough to inject once every four weeks rather than weekly, which is a meaningful difference in adherence over years.
- 03Investigational, and data so far is from conference presentationsPhase 2 results were presented at EASD in 2025. Treat as provisional until published.
Acts on one receptor.
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.

How much, and do you cycle it?
The range, and whether you take breaks.80 up to 160 mg per month (trial doses), monthly. Not cycled in the trialsTrial dose
Given continuously for the whole study period: HORIZON-1, 52 weeks. The dose is stepped up at the start, which is a ramp rather than a cycle, and no trial in this class built in a planned break.
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.

1600 / 100 unitsHow do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized Zovaglutide (ZT-002) keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

Show glossary +
What these words mean
- 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.
