Overview
What it is.
NAD+ is a coenzyme — not a peptide — central to how every cell produces and uses energy, with levels that decline with age. It is one of the most frequently requested compounds alongside peptide research protocols and is included here for that reason.
Research Areas
- Studied for its potential role in cellular-energy-metabolism research
- Studied for its potential role in mental-clarity and focus research
- Studied for its potential role in cellular-aging-process research

How it works.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme — not a peptide — that every cell in the body relies on to produce and use energy. Levels decline measurably with age, which is why it's studied and offered as part of longevity-focused wellness protocols alongside peptides.
NAD+ is a central cofactor in mitochondrial energy metabolism and in DNA-repair and cell-signaling pathways (including sirtuin activity). Supplementing it, or its precursor molecules, is studied as a way to help maintain the cellular NAD+ pool that supports these processes as natural levels fall with age.

- Studied as a companion to peptide-based longevity protocols
The Evidence
Oral precursor trials (NR, NMN) — target engagement
Multiple randomized, placebo-controlled trials of oral NAD+ precursors (nicotinamide riboside, nicotinamide mononucleotide) in middle-aged and older adults consistently show the supplements are well tolerated and reliably raise circulating NAD+ levels.
Functional outcome trials — mixed to limited
The same trials have generally not shown clear improvements in cardiovascular, cognitive, or muscle-strength outcomes; a 2025 systematic review found human effects on metabolic and performance outcomes remain mixed, with small sample sizes and short durations as recurring limitations.
IV/injectable-route trial data
A 2025 PRISMA-guided systematic review found no eligible outcomes trials specifically testing IV or IM NAD+ for anti-aging or wellness purposes — the direct-injection route used in many clinics has less formal trial evidence behind it than oral precursor supplementation.
Animal research
Preclinical studies in rodents show more consistent benefits for metabolism, inflammation, and mitochondrial function, but that evidence has not yet reliably translated into measured human functional gains.

Questions
NAD+ FAQ
Questions
NAD+ FAQ
What is NAD+ studied for?+
NAD+ is studied for its central role in cellular-energy metabolism, alongside research interest in mental-clarity, focus, and cellular-aging-process pathways — its levels are known to decline with age.
Is NAD+ a peptide?+
No — it's a coenzyme, a different molecular class from the peptides in this catalog. It's included because it's frequently studied alongside peptide research protocols.
Why does NAD+ come in sizes up to 1000 mg when most peptides top out much lower?+
As a coenzyme rather than a peptide, NAD+ is characterized and dosed at a different scale in the research literature — the larger vials reduce per-mg cost and reconstitution frequency for extended protocols.
How should NAD+ be handled and stored?+
It ships as a lyophilized powder. Reconstitute with bacteriostatic water and refrigerate at 2–8°C after mixing — good for roughly 4–6 weeks refrigerated, or up to 24 months unreconstituted in a cool, dry place.
