A naturally occurring peptide researched for its role in deep sleep, stress regulation, and recovery.
Researched for its role in sleep depth.
Studied for calming, recovery-oriented pathways.
Designed for research before sleep.
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring peptide studied for its role in sleep regulation and stress resilience.
Evidence is largely preclinical; supplied strictly for research use.
How it works: DSIP is studied for promoting delta-wave (deep) sleep and modulating the stress axis, though its exact mechanism is not fully mapped.
Researched to support: deeper rest, stress balance, evening use.
Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.
Find your protocol →Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.
Administer: Subcutaneous, usually with an insulin syringe.
Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).
Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.
These are research materials, not medical advice. Talk to your doctor before use.
In research use DSIP is handled as a subcutaneous injection, typically before the sleep window:
Describes dosing used in clinical research, provided as reference only — not a usage recommendation or medical advice. This is an investigational research compound.
Sleep research: Early studies explored DSIP for promoting delta-wave sleep and reducing stress markers; controlled human data are limited.
Stress axis: Research examined effects on the HPA (stress) axis.
Status: An investigational research compound; supplied strictly for research use.
Provided as a scientific reference based on published clinical results — not medical advice, a usage recommendation, or a claim about the research product supplied by Novapep.
Digestive effects are the most common and usually ease with gradual titration. Scientific reference only, not usage instructions.
Delivery: FAN Courier, 24 to 48 hours across Romania. Dispatched within 1 to 2 business days.
Free shipping: On orders over 250 lei.
EU orders: Shipped from partner stock, typically within about 14 days.
Payment: Cash on delivery, card on delivery, or bank transfer.
Packaging: Discreet, kept cool after delivery.
Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.
The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.
Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.
Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.
It varies by peptide and protocol. Some are researched over a few days, others over several weeks.
A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.
Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: if you want a vial independently tested, contact us first, we’ll agree a laboratory and pay for the test. If the result doesn’t match the label, we cover the testing cost and replace the product.
