02Overview

What DSIP is

Discovered in 1977 during sleep research — and nearly 50 years later its receptor is still unknown.

Each vial contains 5mg of lyophilised DSIP, supplied as a sterile powder for reconstitution. Delta sleep-inducing peptide (DSIP, emideltide) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) isolated in 1977 from the cerebral venous blood of rabbits during studies of sleep, and named for enhancing slow-wave (delta) EEG activity after brain infusion. Small human sleep studies followed in the 1980s, but its receptor and gene have never been identified and a 2006 review called it "a still unresolved riddle" — which is exactly why it remains of research interest. It holds no registration as a medicine in South Africa in this form and is supplied here strictly as research material. Findings described are from published laboratory, animal and clinical-research literature and are not statements about outcomes for any reader.

Mechanism, as studied

DSIP’s mechanism is unresolved: it was named for its EEG effect, but no receptor or gene has been identified.

05Questions

Before you order

01What purity standard do your peptides meet?

Quality is documented by independent Janoshik Analytical reports (compound identity and HPLC purity) linked from each product page, with unpublished certificates available on request. Each Certificate of Analysis names the compound and reports its HPLC purity; published certificates are at livingwaterlabs.co.za/verify and any other is sent on request.

02Do you provide Certificates of Analysis?

Yes. Our certificates are independent Janoshik Analytical reports naming the compound and its HPLC purity. Published certificates are readable at livingwaterlabs.co.za/verify; for a compound not yet listed there, ask us on WhatsApp and we send it before you order.

03How should research peptides be stored upon receipt?

Peptides should be stored at -20°C in a sealed, dry environment. Once reconstituted, solutions should be stored at 4°C and used within 30 days, or aliquoted and stored at -80°C for longer-term stability. Avoid repeated freeze-thaw cycles.

04How long does delivery take in South Africa?

Orders are packed and dispatched within 1–2 business days and delivered door-to-door by tracked courier anywhere in South Africa. A tracking number is emailed to you when the courier collects. Standard courier is R130.

05What payment methods do you accept?

We accept EFT bank transfer. Banking details are provided at checkout. Please use your order reference number as payment reference so your order can be processed promptly.

06What does "for research purposes only" mean?

It means every product supplied by Living Water Labs is sold as a research chemical for laboratory and scientific investigation only, and is not supplied for human or veterinary use, not for the diagnosis or treatment of any condition, and not as a food, cosmetic or medicine. Living Water Labs is not a pharmacy, makes no medical or therapeutic claims about any product, and does not provide human dosing, treatment protocols, diagnosis or disease recommendations. What we do provide — identity, purity, certificates, literature, molecular data, reconstitution maths, handling and storage — is listed at livingwaterlabs.co.za/faq#research-use. Buyers confirm legitimate research intent at the point of order.
