System Labs review

Publishes the dose

The only provider we have found that states a milligram quantity for every NAD⁺ product it sells — and then explains the one thing about absorption it gets backwards.

Our verdict

On the disclosure that matters most in this category, System Labs is the best we have reviewed. The injection page says 1000 mg. The nasal spray page says 300 mg/ml across 15 ml. Both list a price. The site carries a plain FDA disclaimer. That combination is close to unique here, and it means you can actually calculate what you are buying instead of guessing. The one claim to discount is their case for injecting: they argue oral NAD⁺ breaks down in digestion, which is true and beside the point, because oral precursors are the only format with randomized human trials behind them.

What it is

A cash-pay telehealth platform selling compounded NAD⁺ two ways — subcutaneous injection into the stomach or thigh, and a daily nasal spray — alongside sermorelin, glutathione and a MIC+B12 injection. Clinician review is online, there is no insurance involved, and the kit ships to you.

How it works

A licensed clinician reviews your history before prescribing and can adjust the protocol later. Everything is online and no insurance is required. Medication ships in discreet, temperature-controlled packaging. They describe a specific potency check — a test that the medication contains the correct concentration of active ingredient — which is a more concrete claim than the generic "third-party tested" badge most of this category uses.

Pricing transparency

NAD⁺ injections are $149 a month, discounted to $89 for the first month. The nasal spray is $119 a month, $69 for the first. Read the step-up rather than the headline: the number you will pay from month two is the $149 or the $119. Because both pages publish a quantity, you can do arithmetic almost nobody else in this category allows — $149 for 1000 mg is about 15 cents a milligram. Be careful comparing that against the nasal spray's larger total: milligrams are not interchangeable across delivery routes, and how much of an intranasal dose reaches circulation has not been established.

Branded vs compounded

Compounded NAD⁺, and the site says so — it refers to pharmacy-grade compounds and carries an explicit disclaimer that the medications and therapies offered have not been approved by the FDA and that the FDA has not evaluated the statements about their benefits. Compounded drugs are not reviewed by the FDA for safety, efficacy or quality before dispensing. They do not name the outside compounding pharmacy.

Pros and watch-outs

What we like

  • States a milligram quantity for BOTH products — 1000 mg injection, 300 mg/ml × 15 ml nasal — which almost nothing else in this category does
  • Price published up front on the product page, no intake required to see it
  • Carries an explicit FDA disclaimer rather than implying approval
  • Describes a specific potency test, not just a "lab tested" badge
  • Acknowledges side effects — nausea, headaches, discomfort at higher doses — in its own FAQ
  • Two formats at a real price difference, so needles are an actual choice

Watch-outs

  • "Oral supplements break down in digestion, injections absorb better" is a mechanism argument standing in for evidence the injections do not have
  • The $89 and $69 are first-month prices; the real rates are $149 and $119
  • The compounding pharmacy is not named
  • "Science-backed treatments" is doing a lot of work for a product with no controlled outcome trials
  • NAD⁺ sits alongside sermorelin and glutathione, so this is a peptide-menu platform rather than a NAD⁺ specialist

Best for

Someone who has decided on an injection or a spray and wants to know what they are actually getting for the money — this is the roster's clearest answer to "how many milligrams?"

Who should look elsewhere

Anyone still deciding whether NAD⁺ is worth it. Nothing here changes the fact that the injectable and intranasal formats have no controlled outcome trials, however precisely the dose is stated.

Frequently asked

How much does System Labs NAD⁺ cost?
Injections are $149 a month with a $89 first month. The nasal spray is $119 a month with a $69 first month. Shipping is free. The first-month figures are introductory — budget on $149 or $119.
What dose do you actually get?
This is where they stand out. The injection page states a monthly supply of 1000 mg; the nasal spray page states 300 mg/ml across 15 ml. Most providers in this category publish neither, which makes their prices impossible to compare. At $149 for 1000 mg the injection works out around 15 cents a milligram.
Is the nasal spray better value than the injection?
It is cheaper per month, and it contains more total milligrams, but those two facts do not combine into "better value". Milligrams are not equivalent across delivery routes — how much of an intranasal dose reaches the bloodstream has not been established in controlled human studies, and neither format has outcome trials behind it. Treat the choice as needles versus no needles, at $149 versus $119.
They say injections absorb better than capsules. Is that right?
The mechanism is real and the conclusion does not follow. Oral precursors — NR and NMN — are the only NAD⁺ formats with randomized human trials showing they reliably raise blood NAD⁺, and they cost a fraction of any injection. Injectable NAD⁺ has no controlled outcome trials at all. Higher bioavailability is a reason to expect something; it is not a demonstration that it happened.
Is it compounded?
Yes, and unusually for this category they do not obscure it. The site refers to pharmacy-grade compounds and carries a disclaimer stating the therapies have not been approved by the FDA and that the FDA has not evaluated the benefit claims. Compounded drugs are not FDA-reviewed for safety, efficacy or quality before they are dispensed.
Is System Labs expensive compared with other NAD⁺ injection providers providers?
System Labs publishes a starting figure of $149/mo. Across the 14 NAD⁺ injection providers providers we review that publish a single monthly figure, those run $29.99 to $249 with a median of $179, which puts System Labs below the median, toward the cheaper end. The other 1 NAD⁺ injection providers providers we review quote only after an intake or price by dose, so they are not in that comparison. A starting figure is not a bill — labs, consultations and shipping are often charged separately, so confirm what your own quote includes.
