What on earth is DSIP?
DSIP stands for Delta Sleep-Inducing Peptide. It is a nonapeptide, which is just a fancy way of saying it is a small string of nine amino acids that your body actually makes on its own.
Think of it as a natural supervisor for your internal clock. It works by influencing your neuroendocrine function (your hormone system) and cortisol regulation (how your body handles your main stress hormone).
How does it work in the brain?
This peptide gets its hands dirty by acting directly on your sleep neurochemistry, which is the chemistry of how your brain handles rest. It also talks to your circadian rhythm, otherwise known as your internal twenty-four-hour body clock.
Specifically, it influences two very important pathways:
- GABA signaling: This is a chemical that generally helps calm the nervous system.
- Serotonin signaling: This is the brain chemical often associated with mood and sleep cycles.
Does it actually work?
Well, that is where things get a little vintage. Most of the evidence we have comes from small studies conducted in the 1980s and 1990s. Those researchers saw signs that it improved sleep quality, but they were dealing with very small groups of people.
In the world of science, we currently give it a Grade: C. This is mainly because the human body is complicated and scientists are still working on this one. There have been no modern large-scale Randomized Controlled Trials (RCTs), which are the gold-standard tests doctors like to see before they get excited.
What do the regulators say?
The short answer is: they are not convinced yet. Here is the current score card for DSIP:
- FDA Approved: No.
- 503A Status: It was placed in Category 2 as of September 2023.
- Warning Letters: The FDA sent a warning letter regarding this peptide to Tailor Made in 2020.
The bottom line
While this peptide is naturally occurring and has been studied for decades, we are still waiting for modern science to catch up with the old data. There is a very limited amount of new information available, and no large-scale RCTs have ever been conducted.
This is a great one to bring up with your doctor. You can find peptide-experienced physicians in our Find a Doctor directory.
