GLP3-R 30mg

Description

GLP3-R 30mg from Certified Peptides is 30mg of GLP3-R (retatrutide) in a sealed glass vial. GLP3-R is a GIP, GLP-1 and glucagon receptor agonist. It’s intended for lab research only.

About GLP3-R (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 GLP3-R 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 GLP3-R 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.

GLP3-R 30mg vs related compounds

Here’s how GLP3-R 30mg fits among related compounds. GLP3-R hits GLP-1, GIP and glucagon receptors, the triple agonist with the biggest phase 2 numbers so far. By comparison:

• GLP1-S acts on the GLP-1 receptor only and lasts about a week, the most studied compound in the group
• GLP2-T adds GIP receptor activity to GLP-1, a dual agonist with larger weight effects than semaglutide in trials
• Cagrilintide works through amylin receptors instead of incretins, often studied next to or with semaglutide

The main difference between these compounds is which receptors they hit. Pick the one that matches the receptor question in your study, and use the others as comparisons. See them all on our GLP-1 peptides page.

GLP3-R 30mg reconstitution and concentration

The amount of liquid you add sets the concentration. For a vial holding 30mg:

• 2mL of bacteriostatic water gives 15mg/mL
• 3mL of bacteriostatic water gives 10mg/mL

Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label. The vial itself holds 3mL, so that’s the upper limit.

Most labs use sterile bacteriostatic water; we sell it in 10mL and 30mL vials. Warm the sealed vial to room temperature, add the water slowly along the glass wall and swirl gently until it’s clear. Never shake it.

Storing GLP3-R 30mg

Store sealed vials of GLP3-R 30mg in the freezer (-20°C) or the fridge (2 to 8°C), out of direct light. Mixed solution goes back in the fridge and should be used within about 28 days.

A 6 vial container keeps open and sealed vials upright and apart, which makes the fridge a lot easier to manage. For a bigger collection, the Big Everything Box holds vials and supplies in one latching case.

GLP3-R 30mg purity and lab testing

GLP3-R 30mg is made in the USA, and every batch goes to an independent U.S. laboratory before it’s sold. The lab confirms identity, measures the content and checks purity by HPLC. Our standard is 99% or higher.

You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.

Batches are also screened for endotoxins, heavy metals and sterility. Those contaminant checks matter as much as purity for cell work, where a small amount of endotoxin can skew results.

Choosing a GLP3-R strength

• GLP3-R 10mg: $140.00, about $14.00 per mg
• GLP3-R 30mg (this page): $200.00, about $6.67 per mg
• GLP3-R 40mg: $240.00, about $6.00 per mg
• GLP3-R 60mg: $270.00, about $4.50 per mg
• GLP3-R 120mg: $450.00, about $3.75 per mg

For longer projects GLP3-R 30mg works out cheaper per milligram than the small vial, and you’ll reorder less often.
