DSIP for sleep?

Curious if anyone uses DSIP daily/nightly (via injection) or if you have experience with anything else that helps in a similar fashion, mainly with staying asleep.

I’ve tried melatonin (not helpful) and I take Seroquel for bipolar which knocks me out.

Just curious if there’s something out there I haven’t heard of or something that worked really well for you.

(I could try asking the sleep community for suggestions but don’t typically find anyone well versed in peptides)
