Compared to its siblings.
Glycine (Pharmaceutical)
Inhibitory neurotransmitter. Sleep and muscle relaxation.
Pros
- · FDA GRAS amino acid with Japanese sleep RCT data, versus DSIP's lack of Western Phase 2 evidence.
- · Oral pre-bed dosing avoids injection burden of GH-pulse sleep stacks.
Cons
- · Amino acid, not peptide signaling like DSIP.
- · No GH-pulse benefit that Ipa+CJC pre-bed protocol provides.
DSIP
Delta-sleep peptide. Different mechanism (1970s Russian/Swiss research).
Pros
- · Peptide signaling
Cons
- · No Western Phase 2 evidence
