Our peptides are manufactured under strict quality and control standards. Each product is delivered in lyophilized form , which ensures stability and prevents quality deterioration during transportation, even under adverse conditions . We test every batch.

We do not offer ready-made aqueous solutions because in them the peptide molecules are significantly less stable . The presence of water accelerates processes such as hydrolysis , oxidation and aggregation , which leads to a gradual loss of activity and effectiveness of the peptides.

Even under optimal conditions, the shelf life of peptide solutions is limited to about 4 weeks . Unlike aqueous solutions, the lyophilized form preserves the structure and biological activity of the peptides for a long period - up to 24 months under refrigerated conditions and up to 4 months at room temperature.

When stored in a refrigerator at 2°C – 8°C, the shelf life is up to 24 months . If kept at room temperature , stability is maintained for approximately 3–4 months .

After reconstitution, the peptides are in a more unstable form and should be stored in the refrigerator for up to 4 weeks.

At PurePeptide, we provide fast and secure delivery. Orders are processed within 1–3 business days and delivered to your address in less than a week.

Standard delivery time is 3–7 days , with most shipments arriving within 2–3 days . After shipment, you will receive a confirmation email.

With us, you can rest assured that your order will arrive quickly, reliably, and in excellent condition.

Work in a clean environment and use sterile supplies .
Cool the peptide and bacteriostatic water in the refrigerator.
Using a sterile syringe, withdraw the required volume of bacteriostatic water .
Point the needle towards the inner wall of the vial with the lyophilized substance and slowly add the bacteriostatic water.
Gently swirl the vial until the powder is completely dissolved.
Store the reconstituted solution in a refrigerator at 2–8°C. Its shelf life under these conditions is 4 weeks .

What is DSIP?

Name: DSIP (Delta Sleep Inducing Peptide) 5mg
Brand: PurePeptide
SKU: PP-DSIP-5MG

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide originally discovered in mammalian brain tissue in the 1970s. It is an octopeptide that has been studied in the scientific literature for its role in sleep regulation, stress response, and neuroendocrine balance. In research settings, DSIP has been studied as a modulator of homeostatic processes related to sleep, cortisol levels, and adaptation to psychophysiological stress.

In preclinical and clinical studies, DSIP has been the subject of interest for its potential ability to promote deep (slow-wave) sleep, stabilize circadian rhythms, and reduce excess cortisol secretion. Some studies have also considered DSIP as a co-regulator of other neurohormones - somatotropin, prolactin, and ACTH - in the body's adaptation to exertion, fatigue, and chronic stress.

DSIP observations

In the scientific literature, DSIP has been studied for its possible role in:

Improves sleep quality - helps enter deep sleep and stabilizes circadian rhythms
Regulation of cortisol levels - potential effect on stress response and homeostasis
Supports neuroendocrine function - balances the secretion of hormones involved in sleep and adaptation
Neuroprotection - potential antioxidant and anti-stress effect on the central nervous system
Stimulation of recovery processes - studied in cases of physical and mental fatigue
Mood modulation - some studies discuss involvement in serotonergic regulation

Scientific data

DSIP has been studied in various fields - neuroscience, psychoneuroendocrinology, sports physiology, and gerontology.

In sleep studies, an increase in deep phases (NREM) and better sleep quality have been observed
In models of stress and fatigue, a reduction in cortisol and improvement in recovery performance are reported.
Under chronic stress, DSIP has been studied for its effect on neuroendocrine balance and adaptation.
In neurology, its potential neuroprotective function against oxidative stress is being examined.
In sports medicine, it is analyzed as a factor for faster recovery in the absence of sufficient sleep.

Dosage and administration

The scientific literature describes subcutaneous administration once daily at 100-300 μg daily, usually in the evening before bedtime. It is used to study neuroendocrine mechanisms, with no approved therapeutic dose.

At 5 mg + 3 ml bacteriostatic water:

Concentration = 1.67 mg/ml → 0.06 ml = 100 μg

Example values:

0.06 ml = 100 μg

0.12 ml = 200 μg

0.18 ml = 300 μg

0.24 ml = 400 μg

0.3 ml = 500 μg

Application in sports and research settings

DSIP is not intended for use in sports, but it is being investigated in the scientific literature for its potential role in adaptation to exercise and sleep regulation in highly trained individuals. Due to its possible effects on cortisol and recovery, DSIP is included in the WADA list of peptides that are subject to control in professional athletes.

May help normalize sleep during intense training regimens
It is being studied as a possible factor for better adaptation to chronic fatigue.
Potential synergy with peptides regulating the GH/IGF-1 axis

Possible side effects

In research settings, DSIP is generally well tolerated. The reported reactions are rare and dose-dependent:

Transient drowsiness or fatigue after administration
Mild dizziness or drop in blood pressure
Headache, hot flashes, or feeling relaxed

At higher doses, isolated cases of mild hypotension and decreased concentration have been observed due to the sedative effect.
