NAD+ is not a peptide. It is a coenzyme called nicotinamide adenine dinucleotide; peptides are chains of amino acids.
“NAD peptide” is common shopping language because some sellers list NAD+ alongside peptides. The category on a storefront does not change the ingredient's chemistry or establish its suitability for injection.
NAD+ is not a peptide. It is a coenzyme called nicotinamide adenine dinucleotide; peptides are chains of amino acids.
Why do people call it a peptide?
A clinic may group several products under “peptide therapy,” and a laboratory supplier may sell NAD+ in a similar-looking vial. Search engines then repeat the wording. When comparing products, replace that umbrella label with four specifics: chemical ingredient, amount, concentration if liquid, and intended route. Those details matter more than the shelf category.
Does a 500 mg vial mean a 500 mg dose?
No. A vial's total contents are different from the amount prescribed for one administration. A label saying “NAD 500,” “NAD+ 1000,” or “NAD peptide 500 mg” is incomplete as a dosing instruction. Our label guide explains why milligrams, milliliters, and syringe markings cannot be substituted for each other.
Is NAD like sermorelin or MOTS-c?
These names refer to different substances with different targets and evidence. A cellular-energy theme does not establish equivalent effects, interchangeable doses, or a safe combination. Ask for the reason each ingredient is proposed and the evidence for that exact combination. Our combination-product guide covers the questions to bring to a prescriber.
Are research peptides safe to inject?
A research-only label is not a prescription or proof of a sterile medicine. Purity testing for identity or chemical content also does not establish sterility or acceptable endotoxin levels. FDA has specifically discussed unsuitable ingredients used in sterile NAD+ compounding. Do not turn a laboratory product into an injectable medicine using an online mixing chart; ask a licensed clinician and dispensing pharmacist about legitimate care.
What should a treatment description say instead?
Look for “compounded NAD+ injection,” “oral nicotinamide riboside,” or another precise description that matches the label. Ask who prescribes, which pharmacy dispenses, what follow-up is included, and whether claims come from a study of that route. Provider reviews can help compare the public information, while benefits and evidence explains the limits behind the promises.
