Frequently Asked Questions
What is DSIP peptide?
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit brain tissue, studied for its association with delta-wave sleep and circadian rhythm regulation. Peptalix Labs supplies DSIP 10mg at 99.48% purity, confirmed by Freedom Diagnostics.
What purity is Peptalix Labs DSIP 10mg?
Independently batch-tested at 99.48% purity by Freedom Diagnostics using HPLC-UV and mass spectrometry. Net content 11.10mg per vial, Lot 142-03-DK, Accession #2606120664, with a negative fentanyl screen.
What does DSIP stand for?
DSIP stands for Delta Sleep-Inducing Peptide, named for its studied association with delta-wave (deep) sleep stages in early animal research.
How is DSIP peptide stored?
Supplied as white lyophilised powder. Store the sealed vial at -20C prior to reconstitution. Once reconstituted with bacteriostatic water, store at 2-8C and use within 28 days.
How do I reconstitute DSIP 10mg?
Draw the desired volume of sterile bacteriostatic water into a fresh syringe and inject slowly down the inner wall of the vial. Gently swirl until fully dissolved. Never shake.
What research has been published on DSIP?
DSIP has been studied since the 1970s for its proposed role in sleep-cycle regulation, stress-response modulation, and circadian rhythm research, with an extensive peer-reviewed literature base.
Can I buy DSIP peptide online in the USA?
Yes. Peptalix Labs offers DSIP 10mg for purchase online for qualified USA researchers. COA-verified at 99.48% purity, GMP-sourced, same-day shipping.
Does Peptalix Labs ship DSIP internationally?
Yes, to Canada, Australia, the United Kingdom and most of Europe, with tracked delivery in 5-12 business days.
What is DSIP peptide nasal spray?
DSIP peptide nasal spray refers to an aqueous intranasal formulation studied in some sleep-research protocols. Peptalix Labs supplies DSIP 10mg in lyophilised powder form, reconstituted per the researcher’s own protocol.
What is the appearance of DSIP 10mg?
White lyophilised freeze-dried powder, as confirmed in the Freedom Diagnostics COA (Lot 142-03-DK).
Is DSIP peptide legal to buy in the USA?
Yes, as a research chemical for qualified researchers conducting in-vitro laboratory studies. Not FDA-approved for human use. Sold strictly for research purposes.
What is the research dosing chart referenced for DSIP?
Published DSIP research has used varying dosing parameters across different sleep-research study designs. Peptalix Labs does not provide dosing guidance, as our products are sold for research use only.
Which lab verified Peptalix Labs DSIP purity?
Freedom Diagnostics, a US-based independent laboratory operated by Principal Chemist Alex Johnson. Accession #2606120664, reported 06/15/2026.
What are the reported side effects studied with DSIP in literature?
Published literature has examined DSIP’s general tolerability profile in early research, though Peptalix Labs does not provide medical or safety guidance — our products are sold strictly for in-vitro laboratory research.
What other cognitive peptides does Peptalix Labs offer alongside DSIP?
Our cognitive category includes Semax, Selank, the Selank + Semax blend, PE-22-28, and Pinealon — all COA-verified and GMP-sourced.
