GLP-3 RT 5mg

Description

Our GLP-3 RT 5mg vial holds 5mg of lyophilized GLP-3 RT (retatrutide), a GIP, GLP-1 and glucagon receptor agonist. It’s intended for lab research only.

What is GLP-3 RT (retatrutide)?

Retatrutide (LY3437943, often sold as GLP-3R) is a single peptide from Eli Lilly that acts on three receptors: GIP, GLP-1 and glucagon.

It’s still in clinical trials.

How GLP-3 RT works

Retatrutide hits three receptors with one peptide: GIP, GLP-1 and glucagon. The first two are incretins that boost glucose-dependent insulin release and, in GLP-1’s case, curb appetite and slow stomach emptying.

The glucagon part is the unusual bit. Glucagon raises energy expenditure and pushes the liver to burn fat, so pairing it with the incretins is meant to work on both sides of energy balance. That’s the main reason researchers compare it with the dual and single agonists.

Published GLP-3 RT studies

Jastreboff and colleagues reported in the New England Journal of Medicine (2023) a mean weight loss of up to 24% at 48 weeks in a phase 2 trial.

Phase 3 trials are under way.

The primary literature is on PubMed. Here’s a search for retatrutide studies to start from.

Reconstituting GLP-3 RT 5mg

Here’s the math for 5mg of peptide:

• 1ml of bacteriostatic water gives 5mg/ml
• 2ml of bacteriostatic water gives 2.5mg/ml
• 3ml of bacteriostatic water gives 1.67mg/ml

Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.

Bacteriostatic water is the standard choice. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can damage the peptide, so skip it.

How to store GLP-3 RT 5mg

Unopened, keep GLP-3 RT 5mg in a fridge at 2 to 8°C, or in a freezer at -20°C if it’ll be a while before you use it. Keep it out of direct light. Once mixed, keep it refrigerated and use it within about 28 days, which is how long bacteriostatic water stays good after opening.

GLP-3 RT 5mg lab reports and purity

The product photos for GLP-3 RT 5mg include:

• A certificate of analysis with identity, measured quantity and HPLC purity. The Chromate reports also cover sterility and heavy metals.
• An independent Janoshik Analytical test report. You can verify it on janoshik.com with the key printed at the bottom.
• An endotoxin report from a kinetic LAL assay.

GLP-3 RT 5mg FAQ

How much is in the GLP-3 RT 5mg vial?

5mg of lyophilized powder. The amount is printed on the label.

Is it in stock?

Yes, GLP-3 RT 5mg is in stock now.

Is GLP-3 RT the same as retatrutide?

Yes. GLP-3 RT is our product name for retatrutide research material, and the lab reports in the photos identify it as retatrutide.

Which size should I buy?

Pick by how much you’ll use. Bigger vials cost less per milligram, smaller ones mean less sits open in the fridge. The size comparison above lists every GLP-3 RT option.

Is GLP-3 RT 5mg lab tested?

Yes. The lab reports are in the product photos, so you can check purity before you order.
