NAD+ (nicotinamide adenine dinucleotide) is a key coenzyme present in every cell, involved in hundreds of metabolic reactions — above all in energy production (ATP) and DNA repair. The version offered by Peptology is buffered NAD+ 1000 mg — a stabilized, easily soluble form intended for scientific research applications on cellular energy, mitochondria and aging processes.
It is worth emphasizing: NAD+ is not a peptide, but a coenzyme. In the Peptology catalog, however, it belongs to the same research category as mitochondrial and regenerative peptides — peptides for energy and regeneration — because it addresses the same research area: the cell's energy metabolism and mitochondrial function.
A buffered formula means the pH has been stabilized — raw NAD+ is strongly acidic, and buffering reduces this acidity, improving the solubility and stability of the solution under laboratory conditions. It is a research compound — it is not a medicinal product and holds no registration for clinical use in the EU.
In the version offered by Peptology, NAD+ is supplied as a lyophilized powder of high purity, confirmed by independent laboratory analysis (CoA for every batch), at a dose of 1000 mg per vial. The product is intended exclusively for scientific research and in vitro applications.
In the scientific literature, NAD+ is described as a central hub of cellular metabolism. Below are the three most frequently studied mechanisms.
MITOCHONDRIA / ATP
As an electron carrier in the respiratory chain, NAD+ participates in the production of ATP — the cell's main energy carrier.
DNA REPAIR (PARP)
NAD+ is a substrate for PARP enzymes involved in repairing DNA damage and in the response to oxidative stress.
SIRTUINS (SIRT1–7)
As a cofactor of sirtuins, NAD+ is studied in the context of metabolic regulation, longevity and the cell's stress response.
The level of NAD+ in cells naturally declines with age, which makes it a frequent subject of research on aging and energy metabolism. NAD+ links three areas: energy production in mitochondria, DNA repair by PARP, and activation of sirtuins — which is why it is described as a hub connecting metabolism, regeneration and the cell's stress response.
In the area of mitochondrial research, NAD+ is sometimes paired with the peptide SS-31, which acts at the level of the mitochondrial membrane as an antioxidant. These data come from preclinical and in vitro studies and do not constitute a claim about the effect of the research-grade product.
Buffered NAD+ is offered in a single lyophilized format — 1000 mg per vial. This is a high mass compared with typical peptides, covering both single in vitro series and longer cellular and animal protocols with higher research-material consumption.
1000 MG
Buffered format
Stabilized pH for better solubility and solution stability. The large mass requires precise calculation of concentration and volume — max. 3 mL of solvent per vial.
The buffered 1000 mg format has confirmed high purity and a laboratory certificate (CoA) for the batch. The choice of solvent volume depends on the scale of the research protocol.
NAD+ is an endogenous molecule with rapid metabolism and intracellular turnover. In a research context the following features are relevant:
NAD+ addresses cellular energy and metabolism at the coenzyme level. For orientation, below we compare it with two popular compounds from the same research category — the mitochondrial peptide SS-31 and the repair peptide BPC-157. They have different points of action and are often studied together.
| NAD+ (this page) | SS-31 | BPC-157 | |
|---|---|---|---|
| Compound type | Coenzyme | Peptide | Peptide |
| Main research area | Cellular energy, metabolism, aging | Mitochondrial protection (antioxidation) | Tissue repair, cytoprotection |
| Point of action | Respiratory chain, PARP, sirtuins | Cardiolipin of the mitochondrial membrane | Angiogenesis (VEGFR2) |
| Dose (this version) | 1000 mg | 10 / 50 mg | 5 / 10 mg |
| Role in the protocol | Energy / metabolic support | Mitochondrial component | Repair component |
These compounds do not compete but address different mechanisms — energy (NAD+), mitochondrial-antioxidant (SS-31) and repair (BPC-157). That is why they are sometimes combined in research.
NAD+ is one of the most intensively studied coenzymes in the sciences of metabolism and aging. Below are the most frequently explored directions — all at the research stage, without confirmed clinical indications.
In research models, NAD+ is linked with improved mitochondrial function and increased ATP production. This is the main reason for interest in it in the context of metabolic fatigue and post-exercise regeneration.
As a cofactor of sirtuins (SIRT1–SIRT7), NAD+ is studied in the context of longevity, metabolic regulation and the cell's stress response. The decline of its level with age is one of the main hypotheses in the biology of aging.
Research is ongoing into the role of NAD+ in neurological health, insulin sensitivity and protection against oxidative stress. It should be emphasized that these are research directions, not confirmed therapeutic applications — research-grade NAD+ is not a medicine for any condition.

All information provided concerns the research literature on NAD+ and should not be interpreted as a promise of effect, an instruction for use or a claim about the effect of the research-grade product offered by Peptology.
Important: The information below describes schedules used in research on NAD+. It is provided for scientific and informational purposes and does not constitute a recommendation for individual use, medical advice or administration instructions. The research-grade NAD+ offered by Peptology is not a registered medicine.
In research protocols, NAD+ is usually administered after reconstitution of the lyophilizate:
In combination protocols, NAD+ is sometimes paired with mitochondrial peptides (SS-31) or repair peptides (BPC-157, TB-500) to study effects at different levels of the cell. These schedules come from the research literature and do not constitute a recommendation for self-administration.
In research observations, NAD+ is described as well tolerated. Some of the reported effects are transient reactions that ease with adaptation. The data come mainly from early observations and intravenous protocols.
Common (mild)
Transient reactions
To take into account
Most of the reported effects are mild and transient, and their intensity often depends on the rate of administration. This information is scientific in nature and does not constitute an instruction for use.
Buffered NAD+ is supplied as a lyophilized (freeze-dried) powder in a vial. In lyophilized form it is stable at room temperature, protected from light and moisture — refrigeration before reconstitution is not mandatory. After reconstitution, stability depends on the solvent used, with Peptide Matrix Water™ significantly extending the solution's lifespan.
Laboratory tip: With your order, you can add Peptide Matrix Water™ to the cart — a stabilizing solution designed for working with reconstituted research compounds. More in the article Bacteriostatic water vs acetic acid vs matrix water.
NAD+ is a coenzyme (nicotinamide adenine dinucleotide), not a peptide. It participates in hundreds of metabolic reactions — mainly in energy production (ATP) and DNA repair. In the Peptology catalog it belongs to the energy and regeneration category because of its application area.
Raw NAD+ is strongly acidic. Buffering stabilizes the pH, which improves the solubility and stability of the solution under laboratory conditions — hence the buffered form is more convenient to work with.
Both concern mitochondria, but at different levels. NAD+ is a coenzyme supporting energy production and metabolism; SS-31 is a peptide acting on the mitochondrial membrane as an antioxidant. In research they are sometimes combined as complementary.
In the research literature, NAD+ is sometimes paired with mitochondrial peptides (SS-31) and repair peptides (BPC-157). These are research schedules, not recommendations for use.
The lyophilized vial is stored at room temperature, protected from light and moisture. After reconstitution, stability depends on the solvent: with Peptide Matrix Water™ — up to 60 days in the refrigerator +2 °C to +8 °C; with bacteriostatic or sterile water — up to 28 days. Avoid refreezing.

Precision pipette
Calibrated, 100–1000 µL — for accurately measuring the volume of solvent added to the vial.
70% alcohol swabs
Two swabs — to disinfect the peptide vial and the solvent vial.
Stabilized solvent for lyophilized peptides. Why this one.
| ✅ Correct | ❌ Mistake |
|---|---|
| Disinfect the vial caps and the work surface with 70% alcohol; wear gloves | Working without disinfection |
| Add the solvent slowly along the vial wall | Direct jet onto the powder — foaming and denaturation |
| Gentle rolling between the palms | Shaking — foam, which denatures peptides |
| 10–15 minutes waiting at room temperature | Mechanical mixing or heating |
| Visual check: clear, particle-free | Working with a cloudy or discolored solution |
⚠️ Maximum 3 mL solvent. The standard vial does not accommodate larger volumes — do not exceed during reconstitution.
👉 For any vial and solvent volume — use the calculator. It calculates the concentration (mg/mL, µg/µL) and the volume per sample (mL, µL).
BEFORE RECONSTITUTION
Room temperature, protected from direct light, in original packaging. Refrigerator not required.
AFTER RECONSTITUTION
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water. Discard any remainder after this period.
FREEZING
Not recommended. Freeze/thaw cycles degrade peptide structure.
1. Shaking "to dissolve faster"
Foam = denaturation. Only gentle rolling between the palms.
2. Inappropriate solvent
For peptide stability use only sterile, specially formulated solvent — recommended Peptide Matrix Water.
3. Ignoring slight turbidity
Not fully clear = the sample does not meet the criteria for use.
4. Taking it out of the refrigerator "for an hour–two"
Short exposures add up and compromise stability.
