The Circadian Stack — Research Peptide Bundle

The Circadian Stack from PeakForce Labs is a multi-peptide research bundle supplied for laboratory research applications. The bundle combines DSIP 10mg, Epithalon 10mg, and Pinealon 10mg, providing researchers with three distinct peptide compounds for controlled investigation involving neuroendocrine signaling, circadian-associated biology, gene expression, and cellular aging research models.

Each compound is supplied separately as a lyophilized powder in a sealed glass vial and independently verified through rigorous third-party analytical testing and comprehensive heavy metal screening.

Analytical Verification

Every peptide included in The Circadian Stack undergoes comprehensive, multi-step analytical testing to support identity, purity, content, and consistency.

Identity Verification: Confirms that the peptide in each vial precisely matches the specified target compound rather than an alternative substance.

Purity Quantification: Measures sample cleanliness by quantifying the percentage of target peptide relative to residual byproducts or impurities.

Net Peptide Content: Assures precise peptide content within each vial to maintain experimental accuracy and consistency.

Visual Appearance: Confirms physical consistency, verifying a clean, uniform, freeze-dried (lyophilized) powder state.

Mass Spectrometry / Molecular Weight: Evaluates molecular mass and related analytical characteristics to authenticate chemical composition.

Research Context

The Circadian Stack is supplied exclusively for research investigation by qualified professionals. DSIP, Epithalon, and Pinealon are distinct peptide compounds that have been investigated independently in experimental models involving neuroendocrine biology, circadian-associated processes, cellular signaling, gene expression, and aging-associated molecular pathways.

DSIP (Delta Sleep-Inducing Peptide) is a short peptide investigated in experimental research involving neuroendocrine signaling, electrophysiological activity, stress-associated biochemical responses, and sleep- and circadian-associated research models. These studies provide a framework for investigating relationships between peptide signaling and biological rhythm-associated processes under controlled experimental conditions.

Epithalon is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly (AEDG). Laboratory research involving Epithalon has examined gene-expression patterns, telomere- and telomerase-associated molecular biology, pineal-associated experimental systems, and aging-related cellular processes.

Pinealon is a short synthetic peptide commonly identified by the sequence Glu-Asp-Arg (EDR). Experimental research involving Pinealon includes investigation of gene expression, neuronal cell models, cellular signaling, and molecular processes associated with neurobiology and cellular aging.

Providing all three compounds within a single research bundle allows investigators to obtain independently prepared and analytically verified materials for experimental designs involving multiple peptide systems. The bundle does not imply that the compounds must be combined or that a synergistic biological effect has been established.

The Circadian Stack is intended solely for in vitro research and laboratory investigation by qualified personnel in appropriate research environments.

Reconstitution and Storage

Lyophilized storage: Store each vial sealed in a cool, dry location away from direct light
