Lab verification
Which Vitality Chems lot reports has the lab confirmed?
By Collin Keane, Vitality Chems · Published · updated · vendor-authored explanatory note
Short answer
We publish 5 lot reports, all from Vanguard Laboratory. 4 have a lab-hosted record you can open yourself; retatrutide 30mg lot RT3042126 is not in the lab's public lookup, and the lab confirmed by email that the report is genuine (copy on request). Reports describe only the sample tested, and not every catalog item has a published report.

This report is not in the lab's public lookup. On 2026-11-01, Vanguard Laboratory confirmed in writing that the report matches its records and is genuine, and that the purity and quantity figures are correct. Authenticity confirmed by Vanguard Laboratory by email; a copy of the report and the lab's reply is available on request.
The report itself states that its results relate only to the portion of the sample tested, and that the lab did not take part in selecting the sample and cannot confirm that it represents the lot. The confirmation covers this report only. It does not cover other lots and does not show which lot a given vial came from, so ask us to match your lot before relying on it.
How to verify a report yourself
It takes a few minutes and needs only the report and your vial label.
- Match the lot or sample ID on the report to the label on your vial. A report for another lot describes a different sample.
- Open the lab's own record: for a report with a lab-hosted record, use the Verify at the lab link or type verifiedbyvanguard.com yourself and search.
- For a report that is not in the lab's public lookup, email hello@vitalitychems.com for a copy of the report and of the lab's written confirmation, or contact the lab directly at testing@vanguardlaboratory.com with the lot number.
- Compare compound, lot, report date, method, purity and quantity with your copy. If any value differs, treat the report as unconfirmed.
What these reports do and do not show
Purity on these reports is chromatographic purity by HPLC-UV/VIS: the share of UV peak area in the main peak. It does not count water, counter-ions or solvents, and it is not an identity result by mass spectrometry.
No sterility or endotoxin result is listed on these reports, so they say nothing about either. Each report covers one tested sample; it is not a statement about every lot, and not every catalog item has a published report. Where none is published, the product page says a lab report is available on request.
Vanguard Laboratory is an A2LA-accredited lab (certificate 6377.01); peptide purity and quantity testing are not in its accreditation scope. Research use only: all catalog materials are for in-vitro laboratory research and are not for human or animal use.
