GLP3 retatrutide 10 mg kit: carton with a lyophilized retatrutide vial and bacteriostatic water

Purity ≥ 99%

HPLC resolves retatrutide from related peptide impurities and reports peptide purity as a share of total peak area. Every lot is tested by independent laboratories.

Quantity verified

Peptide purity is a ratio — it cannot tell you how much is in the vial. The certificate states the measured mg per vial, so a 10 mg vial is confirmed to hold 10 mg.

Endotoxin tested

Bacterial endotoxin is measured by LAL assay and reported in EU per vial — contamination that a purity chromatogram is incapable of reporting as precisely.

The science of "GLP3"

One molecule, three targets.

Retatrutide is a triple agonist: a single 39-amino-acid peptide engineered to activate the GLP-1, GIP, and glucagon receptors simultaneously. This multi-receptor approach integrates distinct metabolic signaling pathways within one research molecule.

Common questions

Is every batch tested for purity?

Yes. A sample from each lot of retatrutide is analyzed by an independent third-party laboratory before it is offered for sale. We publish the certificate of analysis (COA), covering HPLC purity, mass-spec identity, and endotoxin results, on our Lab Reports page. We guarantee ≥ 99% purity.

How fast do orders ship?

In-stock orders placed before 1pm ET on a business day ship the same day from our United States facility. Every order goes UPS two-day, with Overnight available at checkout, and every order includes tracking.

How should the vials be stored?

Lyophilized (freeze-dried) retatrutide is stable at room temperature, so it ships and stores dry without refrigeration. Keep vials away from light. Once reconstituted, store refrigerated at 2 °C to 8 °C and use within the window noted on the COA.

Will the peptide degrade in transit?

No. In lyophilized form the compound is stable at ambient temperatures for the duration of normal shipping. Our stability documentation is available with each batch's COA.

Do you offer bulk or wholesale pricing?

Yes. We offer multi-vial kits at a reduced per-vial rate, and larger research-quantity pricing is available on request. Reach out through our Contact page for a quote.
