All articlesDopamine 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.
Sleep Architecture and Cognition: How Sleep Stages Shape Memory, Learning, and Brain Health
A research-focused breakdown of how NREM and REM sleep stages drive memory consolidation, synaptic homeostasis, glymphatic waste clearance, and long-term cognitive performance.

An evidence-grounded comparison of 5-HTP and L-tryptophan for serotonin biosynthesis — covering the TPH rate-limiting step, peripheral conversion concerns, SSRI interaction safety, and the small RCT evidence base for mood and sleep.
Methylene Blue at Low Doses: Mitochondrial Mechanism, Cognitive Evidence, and Serious Drug Interactions
A research overview of low-dose methylene blue (0.5–4 mg/kg) as a Complex IV electron acceptor, MAO-A inhibition at higher concentrations, the SSRI serotonin syndrome risk, fMRI cognitive evidence, and the USP-grade purity question.
Exercise, Neurogenesis and BDNF: How Aerobic Training Works
How aerobic exercise drives hippocampal neurogenesis via BDNF — lactate, irisin/FNDC5, IGF-1, VEGF pathways, Erickson 2011 evidence, and a zone 2 vs HIIT protocol.
PQQ (Pyrroloquinoline Quinone): Mitochondrial Biogenesis and Cognitive Research
PQQ sits at the intersection of mitochondrial biogenesis research and cognitive supplementation, with mechanistic evidence for PGC-1α activation, a durable redox cofactor role, and small RCTs on memory and attention. Here's how it compares to CoQ10 and what current dosing data suggests.
