The strongest human clinical evidence is for topical use, including the Leyden 2002 photoaging trial and a 2023 NEEL gel topical study reporting an average 28% increase in skin collagen density at 3 months
It is produced to pharmaceutical-grade specifications including endotoxin testing below 0.25 EU/mL, sterility confirmation by membrane filtration, particulate matter compliance, and pH within the 4.57.0 range ensuring it introduces no contamination into reconstituted research compound solutions
So we will increase from 250mg to 500mg and sustain that through to our maintenance schedule
Currently, human clinical trials havent yet been established within the peer-reviewed literature. At present, most of the published evidence regarding this peptide falls within the first two categories
