Pinealon

Khavinson tripeptide (Glu-Asp-Arg) that crosses the blood–brain barrier and regulates brain tissue.

Pinealon is one of the short Russian "bioregulator" peptides — a three-amino-acid sequence small enough to slip across the blood–brain barrier and act directly on brain tissue. It's used as a gentle neuroprotectant and cognitive support, especially in older users, with antioxidant effects that help shield neurons from oxidative stress. Think maintenance and protection rather than acute focus — it's run in short courses, often alongside Epitalon in the Khavinson longevity protocols.
