02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Sequence
Side-chain composition
Every heavy atom is placed from the sequence with ideal bond lengths and angles, so the connectivity is exact. The pose is idealised (an extended chain) and is not a measured conformation. Identity for each lot is confirmed on its certificate.
Structure viewer04In the lab
Pinealon is a synthetic Glu-Asp-Arg tripeptide and no receptor for it has been identified. In laboratory research it limits reactive oxygen species and necrotic death in neuronal cells, and biophysical work shows it can enter the DNA major groove.
Compound
PinealonSynthetic Glu-Asp-Arg (EDR) tripeptideGranule and PC12 cells
Endpoint studied
Less ROS buildup and necrotic death under oxidative stress, with delayed ERK 1/2 activation.
Khavinson 2011 · PMID 21978084Purified DNA
Endpoint studied
Spectral, NMR and modeling data show EDR partly entering the DNA major groove; Mg2+ ions promote binding.

Rejuvenation Research
Pinealon limits ROS buildup and necrotic death in cerebellar granule cells, neutrophils and PC12 cells, with delayed ERK 1/2 activation.
PubMed · PMID 21978084Advances in Gerontology = Uspekhi Gerontologii
In an acute hypoxia model, brain caspase-3 and serum IL-6 and TNF were tracked; neuroinflammatory reactions returned toward reference levels.

EDR partly enters the DNA major groove and contacts guanine N7 and O6; magnesium ions promote the interaction.
PubMed · PMID 30762356Molecules (Basel, Switzerland)
A review proposes EDR enters cells, binds histones or RNA, and shifts MAPK/ERK signaling and caspase-3, p53, SOD2 and GPX1 synthesis.

About Pinealon, its certificate and your order.
Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-PIN-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
