GLP-3 RT 20mg

Description

GLP-3 RT 20mg is a 20mg vial of GLP-3 RT (retatrutide), a GIP, GLP-1 and glucagon receptor agonist, supplied by Evolve Peptides as freeze-dried powder. It’s sold for laboratory 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.

GLP-3 RT research

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 20mg

Here’s the math for 20mg of peptide:

• 1ml of bacteriostatic water gives 20mg/ml
• 2ml of bacteriostatic water gives 10mg/ml
• 3ml of bacteriostatic water gives 6.67mg/ml

Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.

Most labs use bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll it gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.

How to store GLP-3 RT 20mg

The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.

GLP-3 RT 20mg lab reports and purity

The product photos for GLP-3 RT 20mg 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.
