The hypothalamic pulse generator runs chaotically rather than in the ordered rhythm ovulation requires
By attaching a larger molecule, like a polyethylene glycol (PEG) chain (a process called PEGylation), scientists can make the peptide too large to be easily filtered by the kidneys and can also sterically hinder the approach of degrading enzymes
The Protocol Components includes in The Circadian Stack: DSIP 10mg : Delta Sleep-Inducing Peptide studied for its role in modulating neuroendocrine responses and observing the induction of slow-wave sleep patterns in research models
R 3 is H, C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, optionally substituted C 3 -C 6 cycloalkyl, optionally substituted C 2 -C 7 heterocycloalkyl, optionally substituted C 6 -C 10 aryl, optionally substituted C 3 -C 9 heteroaryl, OR 6 , NR 5 R 6 , C(O)R 7 , -0O 2 R 6 , C(O)NR 5 R 6 , N(R 5 )C(O)R 7 , N(R 5 )CO 2 R 7 , NHS(O) 2 R 7 , S(O) 2 NR 5 R 6 , or R 2 and R 3 together form an optionally substituted C 2 -C 7 heterocycloalkyl ring
More important than concentration is the formulation's pH stability (GHK-Cu is stable between pH 5.0 and 6.5) and the carrier's ability to deliver the peptide past the skin barrier
