Peptide Quality & Testing Standards
At Renuvia Labs, quality is not a marketing line. It is the framework around which every product, process, and decision is built.
From sourcing to your bench
What happens to every batch
Quality here is a process you can follow, not a badge. Each step below is something you can check on a product page or in the COA library.
Specification
Sourced to a defined specification
Identity, fill amount and form are defined before a product is listed, and each product page describes only what can be documented.
Batch
Every batch is numbered
Batch numbers tie each vial to the documentation that describes it.
Testing
Batch report issued
When a report is issued it lists the laboratory, date, methods and results. We never show a purity figure without the report behind it.
Batch reports pendingPublished
COA added to the public library
Searchable by product, SKU or batch, and linked from the product page.
Shipping
Sealed and shipped
Peptides ship as lyophilized (freeze-dried) powder in sealed vials, the most stable form for storage and transit.
What we will not do
No invented purity claims, no fake reviews or badges, and no dosing or human-use guidance. If something is not documented yet, we say so.
Where testing stands today
Renuvia Labs launched in 2026 and first-lot reports are still being issued. Until a lot's report is published, its product page and the COA library show "Batch report pending" instead of a purity figure. A published report names the laboratory, the date, the methods used and the results, and states which tests were not performed. Reports are added to the library as they are received.
Certificate of Analysis
What every published report shows
Identity. Confirms the vial contains the compound on the label, usually by mass spectrometry (molecular weight) and HPLC retention time. A published report names the method and the laboratory.
Purity. The share of the measured material that is the target compound, typically by HPLC. Renuvia only shows a purity figure that comes from a published report, never from a label.
Content. Net peptide content: how much of the vial's powder is peptide rather than counter-ions and moisture. Not every laboratory reports it; the report says when it does.
