peptides for sleep

Sleep-related peptides discussed include pinealon (also called pinealine), sermorelin, and ipamorelin; reported effects vary between people.

• Pinealon with glycine: Huberman reported that injectable pinealon combined with glycine doubled his REM sleep in his own tracking, but said he used it only occasionally. The guest described glycine as calming and potentially helpful for settling down at bedtime. These are individual reports, not a guarantee of the same response for others. 1 2
• Sermorelin: Huberman reported that it increased his deep sleep but sharply reduced or eliminated his REM sleep; he also noted that responses differ from person to person. 3
• Ipamorelin: The guest described people sleeping somewhat better with it, while characterizing it as having few side effects at the dose discussed. 4
