The report for the exact lot we’ll ship you.
Not a generic sample. Every lot is tested by an independent lab, and every vial carries a QR that opens its own lot’s report — so the paper always matches the bottle in your hand.

The share of the vial that is the target peptide versus impurities — separated by HPLC and confirmed by mass spectrometry.
Mass spectrometry confirms it is the exact peptide on the label — right mass, not a look-alike.
Screens for toxic metals (lead, arsenic, cadmium, mercury) left from manufacturing; must stay under safe limits.
Checks for bacterial toxins that can cause fever or immune reactions, measured by the LAL assay.
Confirms no living bacteria or fungi are present — the contents are sterile.
Put us to the test
Check it yourself. We’ll cover half.
Send your vial to a lab you trust — we’ll cover 50% the testing fee. We’re that sure the report matches the vial.
Just email us first — we’ll point you to the same panel the lab ran so the results are comparable, and set up your 50% reimbursement.What this report does and doesn’t cover
- We test a representative sample of each lot, per industry standard — not every single vial.
- Covers purity, identity, heavy metals, endotoxin and sterility — not whether a dose is safe for any use.
- We’re broadening it over time — more tests, and more independent labs.
GLP-3 RT (research designation for retatrutide, Eli Lilly code LY3437943) is a synthetic 39-amino-acid peptide engineered as a single-molecule triple agonist at the GLP-1, GIP, and glucagon receptors. It carries an Aib substitution and a C20 fatty-diacid side chain that extends its half-life to support once-weekly dosing in the clinical studies referenced below. It is investigational and has been studied in phase 1-2 trials for obesity, type 2 diabetes, and metabolic dysfunction-associated steatotic liver disease. aminobay supplies it as a lyophilized powder for laboratory research use only.
