Quick answer
Pinealon is a synthetic tripeptide, Glu-Asp-Arg, also written EDR. It came out of a Saint Petersburg gerontology institute and is sold as a research peptide. Published work is mostly cell-culture and rodent experiments, much of it from that same institute, plus a few small Russian-language human reports. No studies are registered on ClinicalTrials.gov.
- Class
- Short peptide bioregulator (cytogen)
- Half-life
- Not established in published human data
- FDA status
- Not approved by the FDA; sold for laboratory research use only
Third-Party Testing & Certificate of Analysis (COA)
A certificate of analysis (COA) is a lab document that reports what a specific batch of material actually contains. Reputable research suppliers publish one for every batch, tied to a lot number you can match against the vial you received.
- HPLC — purity
- High-performance liquid chromatography reports purity as a percentage: how much of the sample is the intended compound rather than impurities.
- Mass spectrometry (MS) — identity
- Mass spectrometry confirms identity by measuring the sample's molecular mass, so it matches the peptide the label names.
It also matters who ran the test. In-house results come from the seller's own lab; an independent third-party lab has no stake in the result, so its COA generally carries more weight. Look for a named testing laboratory, a batch or lot number, and a test date that lines up with the vial in hand.
