These effects accumulate in brain tissue and persist longer than the compound remains in the bloodstream: A single dose's effects on synaptic density, VEGF signalling, and neuroprotective cascades may last for hours or days after blood levels have dropped to zero Repeated dosing likely leads to cumulative effectseach dose "adds to" the previous dose's neurobiological changes Anecdotal reports of sustained effects after discontinuation (weeks to months in some cases) are consistent with persistent brain changes rather than active drug presence Implications for Dosing This is a crucial point: the observation that effects outlast blood concentrations explains why some community members report benefits from periodic (not daily) dosing and why cycling protocols exist

53 Since the majority of cells express ERs, estrogen actions influence almost all tissues and are responsible for: a) homeostatic regulation, b) cell proliferation and apoptosis, c) liver protein expression, d) lipid metabolism, e) energy balance, f) glucose metabolism, g) immune and cardiovascular alterations, h) gonadotrophin feedback and gametogenesis, i) brain-neuronal development/memory processing and repair/neurodegeneration, j) bone growth, etc., 7,15,53,60 including estrogens positive (agonist) or negative (antagonist) actions on skin, especially in women
