Mechanism of Action

Mechanism of Action
NAD+ acts as a coenzyme that transfers electrons during cellular respiration, influencing redox balance and ATP production. It serves as a substrate for enzymes involved in DNA repair and cell survival, such as PARPs and sirtuins. Declining NAD+ levels have been linked to reduced energy production and cellular efficiency, making it a crucial variable in research on metabolic aging and recovery.
About

About
NAD+ 1000 mg is formulated for advanced research in energy metabolism, repair pathways, and aging biology. It enables exploration of how cellular energetics relate to mitochondrial health, gene expression, and overall performance. Whether used in oxidative stress models or DNA restoration studies, this high purity NAD+ is designed for precision and reproducibility, helping researchers quantify and restore the cellular energy balance that drives vitality.

Frequently Asked Questions

✧ 1. What are Sunday Health peptides used for?

All Sunday Health products are sold for research use only. They are not intended for human consumption, therapeutic, or diagnostic use. Our peptides are designed exclusively for controlled laboratory research, educational studies, or analytical testing. Every product label and supporting document clearly reflects this compliance standard.

✦ 2. Who is eligible to purchase peptides?

Purchases are available to verified professionals, licensed clinics, educational institutions, and qualified research entities. Individuals may also purchase peptides for legitimate research or educational purposes, but all buyers must acknowledge and agree to Sunday Health’s research-only terms prior to completing any order. We do not sell or endorse products for personal or medical use under any circumstance

♡ 3. How should peptides be handled and stored?

Peptides arrive as a lyophilized (freeze-dried) powder. For laboratory reconstitution, use only sterile bacteriostatic water or sterile saline (0.9 percent NaCl). Gently introduce the solvent and swirl—do not shake. Once reconstituted, store at 35°F to 45°F for short-term use, or at –4°F for long-term preservation. Protect vials from light and moisture, and avoid repeated freeze and thaw cycles to maintain stability.

⟡ 4. Why do peptide vials appear nearly empty?

Because peptides are measured in milligrams, the quantity often appears minimal or as a thin layer within the vial. This is completely normal for high-purity research peptides. Each vial undergoes precision weighing and purity testing using high-performance liquid chromatography (HPLC) and mass spectrometry to ensure the correct labeled amount is present.

✧ 5. What documentation and quality assurances come with each product?

Every peptide includes a Certificate of Analysis (COA) verifying its identity, purity (≥ 99 percent), and composition. Each batch is U.S. sourced and assembled under strict quality oversight and internal auditing. Full lot traceability, validated purity testing, and documentation accompany every shipment to ensure reproducibility, compliance, and scientific reliability.
