How we test
Certificates are issued by independent labs. Identity and purity are measured by LC-MS; endotoxin, where listed, by a LAL screen. The latest report for this option: Identity, purity & endotoxin tested, lot 395336, tested 3 Apr 2026.
How to read your COA
Start with the lot number on the report. Identity confirms by mass spectrometry that the molecule is the one on the label. Purity is the share of the sample that is the target peptide, measured by LC-MS. Endotoxin, where tested, is screened by LAL and must sit below 0.5 EU/mL. The lab name and test date show who ran it and when.

Product overview
DSIP 10mg is suited for research teams investigating neuropeptide signaling dynamics, hypothalamic-pituitary-adrenal (HPA) axis modulation, and circadian rhythm marker expression in preclinical models. Laboratories examining delta-wave-associated peptide activity, neuroendocrine interaction patterns, or corticotropin/ACTH pathway signaling will find this concentration appropriate for multi-month experimental designs. The 10mg format reduces vial turnover across extended protocols, supporting consistent peptide availability throughout the observation period. Produced by Elivena in USA GMP-certified facilities, each vial is COA-verified for purity and peptide sequence identity.
Research focus
Neuroendocrine Signaling Studies
DSIP supports investigation of peptide-receptor interaction dynamics within the HPA axis. Researchers quantify ACTH and cortisol pathway marker activity, receptor occupancy patterns, and downstream signaling cascade responses in preclinical cell-based and in-vivo models. The 10mg concentration provides sufficient material for multi-phase mechanistic studies examining these neuroendocrine endpoints.
Circadian Rhythm Marker Expression
Laboratories studying circadian oscillation and peptide-associated marker expression use DSIP to examine the molecular relationship between neuropeptide activity and rhythm-associated signaling patterns. Research designs typically monitor endpoint expression at defined timepoints across extended observation windows to characterize temporal dynamics.
Extended Multi-Month Protocol Support
The 10mg vial format supports 12–24 week experimental designs, enabling systematic observation of neuropeptide signaling activity across multiple study phases. Higher concentration reduces logistical interruption between phases and supports reproducible, consistent peptide exposure throughout the protocol duration.
Methodological notes
Preparation Guidelines
Reconstitute lyophilized DSIP 10mg with sterile bacteriostatic water using standard sterile laboratory technique. Reconstitution volume should be determined based on the target experimental concentration specified by the study design. Use calibrated laboratory equipment for all preparation steps.
Storage Conditions
Store lyophilized peptide at 2–8°C, protected from light and moisture, prior to reconstitution. Following reconstitution, maintain refrigeration at 2–8°C and use within the timeframe specified in the laboratory protocol. Lyophilized material does not require cold-chain shipping but should be refrigerated upon receipt. Each Elivena vial is supplied with COA documentation and handling guidance.

Key features
Neuropeptide Structural Profile
DSIP (delta-sleep-inducing peptide) is a nonapeptide — a nine-amino-acid chain — first characterized for its association with delta-wave electroencephalographic activity in preclinical models. Its structural profile has since been studied for interactions with multiple neuroendocrine systems, including the HPA axis, making it a relevant model compound for multi-pathway neurophysiological research. The defined molecular weight and sequence support precise dosing and reproducible experimental conditions.
HPA Axis and Neuroendocrine Pathway Interaction
Research using DSIP examines its modulatory activity on corticotropin (ACTH) and cortisol pathway signaling in preclinical models. Studies characterize its interaction with hypothalamic receptor systems and downstream neuroendocrine marker expression. This makes DSIP useful for laboratories investigating peptide-mediated modulation of HPA axis activity, stress hormone cascade dynamics, and feedback regulation mechanisms at the molecular level.
Circadian and Delta-Wave Marker Research
DSIP is studied in relation to circadian rhythm marker expression and delta-wave-associated signaling activity in controlled neurophysiological models. Researchers use it to examine the relationship between neuropeptide activity and oscillatory marker patterns, contributing to mechanistic understanding of peptide involvement in circadian regulatory pathways — without implying direct physiological outcome endpoints.

What documentation accompanies the product?
Each batch includes a Certificate of Analysis confirming identity, purity, and analytical verification results.
Can this compound be used in clinical studies?
No. This material is designated exclusively as a research-use biochemical reagent.
What neuroendocrine pathways is DSIP studied in relation to?
DSIP has been investigated for its interaction with hypothalamic-pituitary-adrenal axis signaling, including modulatory activity on ACTH and cortisol pathway marker expression. It is also studied in relation to circadian oscillation markers and delta-wave-associated neuropeptide activity in preclinical models.
When is the 10mg concentration appropriate for laboratory use?
The 10mg format is suited to extended 12–24 week experimental protocols requiring consistent peptide availability across multiple study phases. Research directors determine whether this concentration efficiently supports their specific throughput and dosing requirements.
Can DSIP be used in combination research protocols?
DSIP may be incorporated into combination preclinical studies alongside other neuropeptide or neuroendocrine research compounds. Protocol design should be based on the specific receptor systems and signaling pathways under investigation, following institutional laboratory safety and ethics standards.

Researchers often ask
Is DSIP for human use?
No. DSIP is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
When will my order ship?
Orders are dispatched within 24–48 business hours. Regular tracked delivery takes 5 to 10 days and express tracked 3 to 5 days. Regular shipping is free on orders over $200 and express on orders over $400, after discounts.
