An evidence-grounded review of the GABAergic system and the compounds that modulate it, from phenibut and L-theanine to ashwagandha and magnesium, including honest risk-benefit analysis.
Dopamine Optimization: The Neuroscience of Motivation, Focus and Reward
A rigorous neuroscience guide to the dopamine system: synthesis, receptors, tonic vs phasic firing, reward prediction error, and evidence-based ways to support it.
Pinealon: The Khavinson Bioregulator Tripeptide and Cognitive Research
Pinealon is a Glu-Asp-Arg tripeptide from the Khavinson bioregulator school, positioned alongside Epitalon as a pineal-tissue-targeted peptide proposed to modulate gene expression. This research review covers the mechanistic claims, preclinical signals, and the sparse human data.
