What it does - plain English
Pinealon is a synthetic tripeptide (a peptide made of three amino acids - the same general structure as the Russian aging-research peptide family that includes Epitalon and Cortagen). Developed at the Khavinson lab in St. Petersburg, it was designed to mimic peptides your pineal gland (a small gland deep in your brain that regulates sleep and circadian rhythm) makes naturally.
The Russian research claims it has neuroprotective effects (protects brain cells from oxidative damage), supports cognitive function, and improves cellular metabolism in the brain. Like Epitalon, it sits in the longevity-and-cognitive-protocol corner that Western research hasn't deeply replicated.
Status
B-tier / Watch. The mechanism is plausible - your pineal gland does make regulatory peptides; the Russian lab's work is methodologically consistent. But the Western trial base is thin.
If you're researching cognitive peptides, Pinealon is in the second-tier category alongside Epitalon and Selank - peptides discussed often in longevity stacks but with shallower evidence than Cerebrolysin or modafinil-style well-studied options.
Legal status
Not FDA-approved. Research-peptide gray zone, same as Epitalon. Compounding pharmacies generally don't dispense it. Sourced almost entirely through research peptide vendors.
Where to source
Research peptide vendors with a COA (Certificate of Analysis - a third-party lab report verifying purity and dose) per batch. No COA, no buy. Period.
Pinealon is one of the peptides where vendor quality varies a lot, partly because demand is small and oversight is thin. The Russian-language sources sometimes recommend specific compounders that are hard to verify from the US.

Two studies worth reading
Neuroprotection in aging brain cells
Khavinson, V. et al., Bulletin of Experimental Biology and Medicine
In-vitro work showing Pinealon protected rat brain cortex cells from oxidative damage (the kind of cell damage that piles up as you age). The paper that motivates the cognitive-protection claim.
Geroprotection review
Khavinson, V. et al., Frontiers in Aging Neuroscience
A review covering Pinealon, Epitalon, and related Khavinson-lab peptides. Useful for understanding the whole lineage of pineal-derived peptides as one research program rather than as separate products.
