Retatrutide 20mg/Vial

What is Retatrutide?

Retatrutide is a triple receptor agonist, a peptide that binds to and switches on three receptors at once: the GLP-1, GIP, and glucagon receptors.

Researchers compare it with peptides that act on just one receptor, such as semaglutide.

What researchers study it for

• Work on three receptors. Labs study how it acts on the GLP-1, GIP, and glucagon receptors at the same time.
• Studies that compare it. Labs compare its effects with those of single-receptor peptides such as semaglutide.
• Fat and energy use. Studies look at lipolysis, or fat breakdown, and track how energy is used in lab models.
• Signals linked to appetite. Research also looks at the signals linked to appetite in lab models.

What you get

One sealed glass vial containing 20 mg of Retatrutide.

How to store it

Keep the sealed vial in a fridge, away from light, and once it has been mixed with liquid, keep it cold and use it within a few weeks.

What else you need

The powder has to be mixed with liquid before lab use. Most labs mix it with bacteriostatic water and also order 1 cc syringes and alcohol prep pads. Labs often compare retatrutide with semaglutide and tirzepatide. For more background, read our retatrutide research guide.

Common questions

Can I buy retatrutide in Canada?

Yes. We sell retatrutide in Canada as a research compound, in a sealed 20 mg vial, and ship it across the country.

Is retatrutide the same as LY3437943?

Yes. LY3437943 is its lab code. Some sellers also call it “reta” or “GLP-3”. All of these names mean the same compound.

How is it different from semaglutide and tirzepatide?

Semaglutide acts on one receptor and tirzepatide acts on two. Retatrutide acts on three: GLP-1, GIP and glucagon.

Is it a powder or a liquid?

It comes as a dry powder in a sealed glass vial. It is mixed with liquid before lab use.

Is it tested?

Yes. Every batch is quality tested before we list it.

Can people use retatrutide?

No. It is sold for lab research only.

Sold for laboratory research only. Not for human consumption.
