Published in-vitro work commonly uses GHK-Cu in the range of 10 nM to 10 M, with 1 M as a frequently reported working concentration
Nothing to complain about
Recently, there has been increased public interest in compounds like BPC-157, a synthetic peptide that is being discussed in research circles and among those exploring experimental therapies for pain management and tissue healing

Stay competitive in the growing field of vitamin therapy
In 1981, for example, a paper published in the International Journal of Clinical Pharmacology, Therapy, and Toxicology described a trial with six volunteers who experienced immediate sleep pressure after intravenous DSIP infusion, as well as increased sleep time, decreased sleep onset, and better sleep efficiency without any sedative effects.13 Three years later, two other human trials across ten test subjects with insomnia found that DSIP administration yielded statistically significant improvements in several key sleep measures fewer sleep arousals, greater sleep efficiency, and increased REM, spindle, and slow-wave sleep.14 The above studies had shortcomings, namely their very small sample sizes, but the sleep-improving effects in cases of insomnia point to DSIPs potential to live up to its name
