DSIP Epithalon Peptide Stack

DSIP Epithalon Peptide Stack is a dual-compound research peptide combination available at ≥98% purity from Direct Anti Peptide. This stack pairs Delta Sleep-Inducing Peptide (DSIP) with Epithalon, two extensively studied neuropeptides of significant interest across multiple fields of biochemical and longevity research. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

The DSIP Epithalon Peptide Stack is designed for qualified researchers seeking a convenient, pre-paired combination of two well-documented research peptides. DSIP has been widely studied for its neuromodulatory properties, particularly in relation to sleep architecture and hormonal signaling, while Epithalon is one of the most researched tetrapeptides in the field of cellular aging and immunological function. Together, these compounds represent a compelling area of scientific inquiry for laboratories focused on neuroendocrinology, chronobiology, and longevity science. Direct Anti Peptide offers this stack as a high-purity, lyophilized research-grade product for in vitro and preclinical investigative use.

Peptide Structure & Amino Acid Sequence

This stack contains two structurally distinct peptides:

• DSIP (Delta Sleep-Inducing Peptide): A naturally occurring nonapeptide with the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. Originally isolated from rabbit brain tissue in 1977, DSIP functions as a neuromodulator with documented interactions across hypothalamic and limbic pathways.
• Epithalon (Epitalon): A synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly, derived from the natural polypeptide epithalamin produced by the pineal gland. Epithalon has been extensively studied for its role in telomerase activation, antioxidant regulation, and immune modulation in preclinical models.

Both peptides are provided in lyophilized powder form, manufactured to ≥98% purity standards as verified by independent analytical methods.

Chemical & Physical Characteristics

• DSIP: Molecular Formula: C₃₅H₄₈N₁₀O₁₅ | Molecular Weight: 848.8 g/mol | CAS: 62568-57-4
• Epithalon: Molecular Formula: C₁₄H₂₂N₄O₉ | Molecular Weight: 390.34 g/mol | CAS: 307297-39-8
• Both compounds appear as white to off-white lyophilized powders
• Both are water-soluble under standard laboratory reconstitution conditions
• Stable under recommended storage conditions prior to reconstitution

Purity & Analytical Verification (HPLC & MS)

Each batch of the DSIP Epithalon Peptide Stack produced and distributed by Direct Anti Peptide undergoes rigorous analytical testing prior to release. Purity is confirmed at ≥98% using high-performance liquid chromatography (HPLC), and molecular identity is verified through mass spectrometry (MS). These dual verification methods ensure that researchers receive compounds of consistent identity, purity, and concentration—critical parameters for reproducible scientific outcomes. Certificates of Analysis (CoA) are available upon request for every production lot.

Quality Control & Lyophilization Integrity

Both peptides in this stack are produced under stringent quality control protocols and subjected to lyophilization (freeze-drying) to maximize shelf stability and preserve structural integrity. The lyophilization process removes residual moisture without degrading the peptide backbone, ensuring that the compound remains biochemically intact during storage and shipping. Each vial is sealed under inert conditions to prevent oxidative degradation. Direct Anti Peptide’s quality assurance pipeline includes lot-specific documentation, batch traceability, and third-party analytical validation.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals in controlled laboratory environments. Standard laboratory safety protocols should be observed at all times when handling research peptides. Appropriate personal protective equipment (PPE) including gloves, lab coat, and eye protection should be worn. Researchers should consult applicable institutional biosafety guidelines and local regulatory frameworks before initiating any study involving this compound. This product is not approved for use in humans or animals under any circumstances.

Reconstitution, Packaging & Storage

• Store lyophilized peptides at −20°C for long-term stability
• Protect from light, moisture, and repeated freeze-thaw cycles
• Reconstitute using sterile bacteriostatic water or an appropriate research-grade solvent as required by your specific assay protocol
• Once reconstituted, aliquot and store at −80°C; use within the timeframe appropriate to your laboratory’s validated conditions
• Each stack is individually packaged and labeled with compound identity, lot number, and purity grade

Intended Research Use & Market Positioning

The DSIP Epithalon Peptide Stack is positioned as a premium dual-peptide research tool for investigators working in the areas of sleep neuroscience, neuroendocrinology, immunological aging, and cellular longevity. DSIP’s documented interactions with sleep-wake regulatory pathways and stress hormone modulation make it a valuable subject of study alongside Epithalon’s well-characterized preclinical profile in telomere biology and pineal-immune axis research. This stack is ideal for researchers seeking to explore potential synergistic interactions between neuropeptide-mediated sleep regulation and cellular aging pathways in controlled in vitro or preclinical settings.
