Overview
Pinealon is the short-peptide bioregulator Glu-Asp-Arg, usually written EDR, one of the tripeptides developed within Vladimir Khavinson's programme of tissue-specific peptide preparations and associated in that work with brain and pineal tissue. This listing supplies it pre-dissolved in an amber bottle with a metered nasal pump, in 15 mL and 30 mL fills, built from ≥99% HPLC-purity peptide with a lot-matched certificate of analysis.
At only three residues and roughly 418 g/mol, EDR is small even by peptide standards. Khavinson-school publications propose that short peptides of this kind interact directly with DNA and chromatin to influence gene expression, and rodent and cell studies from that group have examined neuronal survival under hypoxic and oxidative stress, behavioural performance in ageing animals, and markers of protein synthesis in nervous tissue. Much of this literature originates from a small number of laboratories, so independent replication remains limited — worth noting when planning study design.

Questions about Pinealon Nasal Spray
Is the peptide the same as the Pinealon vial?
Yes. The same ≥99% HPLC-purity Glu-Asp-Arg tripeptide is used, with the same CAS number, formula and molecular weight. The difference is presentation: this arrives pre-dissolved in a metered nasal pump rather than as a lyophilized powder requiring reconstitution.
What does EDR stand for?
It is the single-letter shorthand for the sequence: E for glutamic acid, D for aspartic acid, R for arginine. Pinealon is the trade name used in the Khavinson short-peptide literature for that tripeptide, which is associated there with brain and pineal peptide preparations.
What is the difference between the 15 mL and 30 mL bottles?
Volume only. Both are filled from the same bulk solution at the same nominal concentration, so the 30 mL bottle contains twice as much peptide and supports a longer study window. The loading for your lot is printed on the label.
Do you provide a certificate of analysis?
Yes. Each bottle traces to a lot-matched COA for the peptide used in the fill, covering HPLC purity of ≥99% and mass-spectrometric identity confirmation. Quote the lot number printed on the bottle when requesting it.
