Scale Weight: While less informative than body composition, weekly weigh-ins (same day/time, fasted) establish trends
The skin-specific mechanisms of GHK-Cu include stimulation of Type I and Type III procollagen synthesis, increased production of dermatan sulfate and other glycosaminoglycans, activation of the enzyme lysyl oxidase (which cross-links newly formed collagen), reduction of matrix metalloproteinase-1 (MMP-1, collagenase) activity, and anti-inflammatory suppression of TNF-alpha-induced IL-6 secretion

Semax works through BDNF and neuroprotective signaling: it supports cognitive performance, focus, memory consolidation, and neuroprotection, with effects that begin within hours to days
The absence of IGF-1 pathway activation is also consistently observed across experimental systems, reinforcing its value in studies requiring separation of metabolic and growth-related signaling pathways
