About
DSIP is a naturally occurring nonapeptide known for its role in regulating sleep and stress responses.
Mechanism of Action
DSIP modulates the activity of various neurotransmitter systems in the brain, including serotonin and GABA, and influences the expression of genes related to circadian rhythms. It promotes delta-wave sleep, the most restorative stage of sleep.
Key Benefits
- Promotes deep, restorative delta-wave sleep
- Helps regulate circadian rhythms
- May reduce stress and anxiety
- Can have antioxidant and neuroprotective effects
Clinical Research
Human and animal studies have shown that administration of DSIP can increase the proportion of deep sleep and help normalize sleep patterns in individuals with insomnia. It has also been studied for its potential in managing withdrawal symptoms and stress.
Potential Side Effects
DSIP is generally well-tolerated with few side effects. Some users report vivid dreams or mild headaches initially.
Usage & Dosage
Typically administered via subcutaneous injection before bedtime. Research dosages vary, commonly ranging from 50mcg to 150mcg.
Peptide Storage
Best Practices For Storing Peptides
To preserve the integrity of laboratory results, proper storage of peptides is essential. Correct storage practices can maintain peptides for years and guard against contamination, oxidation, and degradation. If the peptides will be used immediately, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks.
For longer-term storage (several months to years), it is preferable to store peptides in a freezer at -80°C (-112°F). Avoid repeated freeze-thaw cycles and do not use frost-free freezers, as temperatures can fluctuate widely.
Preventing Contamination
To prevent moisture contamination, allow the peptide to come to room temperature before opening its container. Minimize exposure to air; after use, reseal the container under an atmosphere of dry, inert gas (like nitrogen or argon) if possible. Peptides with Cys, Met, or Trp are especially prone to air oxidation.
Storing Peptides In Solution
The shelf life of peptide solutions is far less than that of lyophilized peptides. If peptides must be stored in solution, use sterile buffers at pH 5-6 and separate into aliquots to avoid repeated freezing and thawing. Peptide solutions are generally stable for up to 30 days when refrigerated at 4°C (39°F).
