NAD+
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell, functioning as a cofactor for sirtuin and PARP enzymes and as a substrate in cellular redox reactions and DNA-damage response pathways.
Nicotinamide adenine dinucleotide — a coenzyme central to cellular energy metabolism and sirtuin-pathway signalling, studied for its role in longevity and mitochondrial health.

Cellular Energy & Redox Research.
NAD+ (CAS 53-84-9) is an endogenous dinucleotide coenzyme that declines with age. Research has examined its role in mitochondrial function, SIRT1/SIRT3 activation, DNA repair signalling, and inflammatory regulation. Formula C21H27N7O14P2, MW 663.43 g/mol. IV or subcutaneous protocols require clinical oversight.

Each release is matched with quality documentation through a documented verification path. Identity, purity, and composition test results sit on the product page before you buy.
Every batch is verified by an ISO/IEC 17025-accredited laboratory before release. Identity, purity, and documentation travel with the product — not behind a form.
Sensitive peptides ship in insulated cold packaging with gel packs sized for a 48-hour transit window, tracked door to door.
Everything worth asking before you order.
Shipping, storage, quality, and when to speak to a clinician — without the runaround.
What proof of quality comes with my order?
Every batch ships with a batch code printed on the vial. The matching independent lab report — showing identity, purity, and composition — is linked on the product page and stays on your order page after purchase.
Should I speak to a clinician before using a peptide?
We recommend it — especially if you are pregnant, nursing, managing a medical condition, or combining peptides with prescribed medication. Our product pages are educational. They are not medical advice and they do not replace a conversation with a qualified practitioner.
How should I store my order when it arrives?
Sensitive peptides ship cold. Move them to a fridge on arrival (2–8 °C) unless the product page states otherwise. Lyophilised vials can tolerate short transit at ambient temperature but should not be left unrefrigerated for extended periods once delivered.
Is NAD+ a peptide?
Strictly, no — NAD+ (nicotinamide adenine dinucleotide) is a dinucleotide coenzyme, not a chain of amino acids. It is often grouped with peptide therapies in clinic menus because the delivery format (subcutaneous or IV) and the longevity-research framing overlap, but biochemically it is a different class of molecule.
Why do clinics use NAD+ injections instead of NAD+ capsules?
Oral NAD+ is poorly absorbed intact, so most oral supplements use precursors — NR (nicotinamide riboside) or NMN (nicotinamide mononucleotide) — which the body converts to NAD+. Subcutaneous and IV NAD+ bypass first-pass metabolism and produce measurable plasma elevations in published pharmacokinetic work.
How do I reconstitute a lyophilised peptide vial?
Bring both the lyophilised vial and the bacteriostatic water to room temperature, equalise pressure with a sterile vented needle, then inject the solvent slowly down the side of the vial. Swirl gently — never shake — until clear, and refrigerate at 2–8 °C.
How much bacteriostatic water should I add to my peptide vial?
The calculation is peptide mass (mg) ÷ desired concentration (mg/mL) = volume of bacteriostatic water in mL. For example, a 5 mg vial at 1 mg/mL needs 5 mL; at 2 mg/mL, 2.5 mL. Every Peptyds product page carries a suggested reconstitution volume tuned to the vial size.
How long does a reconstituted peptide stay stable in the fridge?
Most lyophilised peptides reconstituted with bacteriostatic water remain stable for 28–30 days at 2–8 °C, protected from light. A handful of short, fragile sequences — Epithalon among them — drop to roughly 14 days. Never freeze a reconstituted vial.
What side effects are most commonly reported across peptide research?
Across published trials and case series, the most frequent reported events are injection-site reactions (redness, induration, transient discomfort), headache, mild nausea, and temporary fatigue. GLP-1 and dual-agonist class peptides add dose-dependent gastrointestinal effects.
Who should not use peptides?
Peptides are not appropriate for anyone who is pregnant, nursing, planning conception, under 18, managing active cancer, or on immunosuppressants — and competitive athletes governed by WADA must avoid every peptide on the prohibited list. Anyone with a personal or family history of melanoma should specifically avoid melanocortin-receptor agonists.
