Our peptides are produced under strict quality and control standards. Each product is supplied in lyophilized form, which ensures stability and prevents deterioration during transport, even under unfavorable conditions. We test every batch.

We do not offer pre-made aqueous solutions because the peptide molecules in them 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 efficacy 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 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 a temperature of 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 a refrigerator for up to 4 weeks.

At PurePeptide, we provide fast and secure delivery through Econt Express. Orders are processed within 1–3 business days and delivered to an Econt office or personal address with cash on delivery.

Standard delivery time is 1–3 days, with most shipments arriving within 1–2 days. After dispatch, you will receive a confirmation email. You will receive an SMS notification when the shipment arrives at the Econt office.

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

Work in a clean environment and use sterile supplies.
Chill the peptide and bacteriostatic water in the refrigerator.
Using a sterile syringe, draw the required volume of bacteriostatic water.
Aim the needle at the inner wall of the lyophilized substance vial 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

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide, first identified in mammalian brain tissue in the 1970s. It is an octapeptide that has been examined in the scientific literature in relation to sleep regulation, stress response, and neuroendocrine homeostasis. In research settings, DSIP has been used as a model compound to study processes related to sleep, cortisol regulation, and adaptation to psychophysiological stress.

In preclinical and clinical observations, DSIP has been studied for its potential involvement in inducing deep, slow-wave sleep, stabilizing circadian rhythms, and limiting excessive cortisol secretion. Some scientific publications also consider DSIP as a co-regulator of other neurohormonal systems, including somatotropin, prolactin, and ACTH, especially in the context of adaptation to physical exertion, overtraining, and chronic stress.

Observations of DSIP

In scientific literature, DSIP has been studied in connection with several main areas:

Improving sleep quality - associated with easier entry into deep sleep and more stable circadian rhythms
Regulation of cortisol levels - considered a potential modulator of stress response and homeostasis
Support for neuroendocrine function - participates in the balance of hormonal systems related to sleep and adaptation
Neuroprotection - antistress and antioxidant effects on the central nervous system are discussed in research models
Stimulation of recovery processes - investigated in models of physical and mental overstrain
Mood modulation - separate studies examine a potential link with serotonergic regulation

Administration and Dosage

In scientific literature, subcutaneous administration once daily in the range of 100-300 μg daily, most often in the evening before sleep, within research protocols has been described. DSIP is used for studying neuroendocrine mechanisms and has no approved therapeutic dose.

For 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

Scientific Data

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

In sleep studies, an increase in deep NREM phases and an improvement in overall sleep quality have been observed
In stress and fatigue models, reductions in cortisol and improvement in recovery-related indicators have been described
In chronic stress, DSIP has been examined in connection with neuroendocrine balance and adaptive response
In neurological models, its potential neuroprotective activity against oxidative stress is being investigated
In sports physiology, it is analyzed as a factor related to recovery from insufficient or disturbed sleep

Application in Sports and Research Settings

DSIP is not intended for use in sports, but in scientific literature, it is discussed due to its possible role in adaptation to load, sleep regulation, and recovery in actively training models. Due to its potential influence on cortisol regulation and recovery processes, DSIP is among the peptides subject to WADA control for professional athletes.

Investigated in connection with normalizing sleep in intense training regimes
Considered as a possible factor for better adaptation in chronic fatigue
Potential synergy with peptides related to the regulation of the GH/IGF-1 axis is discussed

Possible Side Effects

In published scientific literature, DSIP is generally described as well-tolerated within research settings. Reported reactions are rare, usually mild, and dependent on the amount used:

Transient drowsiness or feeling of fatigue after administration
Mild dizziness or temporary decrease in blood pressure
Headache, hot flashes, or a feeling of relaxation

At higher quantities, mild hypotension and a temporary decrease in concentration have been described in individual observations, likely related to the sedative profile of the compound.
