Our verdict
CoreAge is $93 a month for either the injection or the nasal spray, the lowest published price we can verify, and states the product is compounded in the USA. System Labs is $149 but publishes 1000 mg and carries an explicit FDA disclaimer. If the dose matters to you, $56 a month is what that information costs here. If it does not, CoreAge is cheaper for the same format and says the same thing about compounding.
Scores and verdicts are computed from our published rubric, which does not read commercial status. Where one provider is a paid partner and the other is not, that changes the label on the card and nothing else.
Before you choose either
Ask both for the dose their monthly price buys — most providers in this category do not publish it, and without milligrams the prices are not comparable. Our cost-per-milligram calculator does the arithmetic once you have the numbers. And read what is known about safety — for injectable NAD⁺, less than you would hope.
