I think if you have real sleep issues, these peptides are kind of a waste of time and money, I get just as much deep sleep when I just take trazodone and Apigenin , but sometimes I get more deep sleep when I add in the DSIP, it's just hit or miss and the miss gets expensive after a while, I'll list what my normal sleep stack is
Trazadone 300 mg
Magnesium Bisglysinate 210 mg
Glycine 3-5 g
Apigenin 50 mg
This has been modified as of late, i use to add L theanine and Ashwaganda , but i feel like i got to many things in the mix so i have reduced some , to see how effective the lesser of the stack works, pretty much the same unfortunately
