System Labs Reviews: Every Price Is a First Month

The one-sentence version

System Labs is one of the few providers on this board whose entire catalogue is the thing the board ranks — NAD+ by injection and by nasal spray, sermorelin by injection and orally, plus glutathione — rather than a weight-loss shop with a peptide bolted on. It also does the rarer thing of printing a price on the page instead of hiding it behind an intake. The catch is what the printed price is: every published figure is a first month, shown struck through from a standing rate you start paying in month two. It grades B, 10 points out of 14, and the two points it drops are both about what the page does not say. The grade is computed from published terms alone and cannot see who pays us.

What it is, and who it's for

The operator is System Laboratories, Inc., and the site carries a LegitScript Certified badge. Its menu, verified on 31 July 2026, is: NAD+ injection, NAD+ nasal spray, sermorelin injection, oral compounded sermorelin, glutathione injection, MIC+B12, GHK-CU cream, and compounded GLP-1/GIP.

Read that list next to the rest of this board and the shape is unusual. Most of the providers here are GLP-1 operators that added an anti-aging category; four of System Labs' eight items are the NAD+ and sermorelin routes this ranking is built on, and the GLP-1 line is the appendage rather than the core. If you came looking for a longevity menu rather than a weight-loss menu with one, this is a genuine fit — which is the whole of the four points it takes on the longevity-line factor. On whether that menu is worth buying at all, read what the evidence actually shows first.

What it actually costs

All figures below were read on System Labs' product landers on 31 July 2026, and they are quoted with the qualifier attached because the qualifier is the story.

NAD+ — "$149" struck through to "$89 /first mo."

Sermorelin — "Monthly Supply (5mg)", "$219" struck through to "$109 /first mo." The copy beside it reads "Support deeper sleep, faster recovery, and leaner muscle. All from your own growth hormone."

Compounded GLP-1/GIP — "COMPOUNDED GLP-1/GIP", "Monthly Supply (All doses)", "$179" struck through to "$99 /first mo."

Three products, three prices, and the same structure on all three: the number in large type is a first month, and the number it is struck through from is the rate that follows. $89 becomes $149. $109 becomes $219. $99 becomes $179. Nothing here is hidden — System Labs prints both figures, which is more than several providers on this board manage at all — but a reader who takes the large number as the price has budgeted for the wrong one from the first refill onward.

It is worth being precise about why that still earns the four price-transparency points rather than zero. Our rubric asks for a single all-in figure, visible before you commit, that a buyer with no commitment actually pays. System Labs publishes one: $149 for NAD+, on the same line as the promotional rate, with no prepay term attached to it. Compare that with the providers here whose advertised figure turns out to be a twelve-month prepay, or is quoted only inside the portal — see the Gala Health review and the Shed review for what an unpublished monthly price looks like. A teaser beside a standing rate is a marketing tactic. A price that does not exist until checkout is a different failure, and a worse one.

What every lander includes. All three carry the same four lines: "20% off Rythm blood test", "Injection supplies included", "2-day temp-controlled shipping", and "Ongoing support from a real care team." The last of those is what earns the human-support points — support stated as inside the price, not sold as an upgrade.

The two points it drops, and why

Clinical oversight: zero. Nothing on the lander states whether the clinician visit is included in the published price. That is the whole finding, and we have deliberately not resolved it in either direction. These are prescription products, so a prescriber is involved somewhere; what is not published is whether the $89 or the $149 covers that consultation or whether it is billed separately. Our rubric scores an unstated consult exactly as it scores one billed on top, because a buyer cannot budget for a fee nobody has quoted. If System Labs states the position on the lander, this becomes two points immediately.

Pharmacy disclosure: zero. No dispensing or compounding pharmacy is named, and no compounding standard — 503A or 503B — is claimed. The LegitScript Certified badge is a real signal and worth having, but it certifies the seller's compliance, not the pharmacy that fills the vial; it is not a facility name and not a classification. We applied that identically to Strut Health, whose ACHC seals earned nothing on this factor either. FDA's position on what an unnamed compounder leaves open is blunt: compounded drugs are not FDA-approved, and the agency does not verify their safety, effectiveness or quality before they are marketed¹.

One structural oddity worth knowing. The prices above live on System Labs' product landers. Its own `/nad` path is an intake questionnaire rather than a product page — so a reader who arrives at the site and browses does not necessarily reach the page with the price on it. That is not a hidden price; it is a published price on a page the site's own navigation does not lead with.

The evidence behind what it sells

This is where a good menu meets a thin trial record, and the sermorelin copy is the sharper example. "Support deeper sleep, faster recovery, and leaner muscle. All from your own growth hormone" describes a mechanism accurately and then attaches outcomes to it that the trials did not produce. The study that tested this exact protocol gave GHRH 1-29 nightly for six weeks to eleven healthy men aged 64–76: nocturnal growth hormone rose significantly, but IGF-1 did not change and DEXA-measured muscle and fat did not change². The landmark review of growth hormone in healthy older adults found small body-composition shifts, no proven functional benefit, and significantly more adverse events³. See peptides for longevity.

NAD+ is no better supported, and the specific gap matters here because System Labs sells it as an injection and a nasal spray. The 2026 PRISMA-guided systematic review of NAD+ for anti-aging and wellness screened 113 studies including 33 human intervention trials, found effects on functional, metabolic and vascular outcomes "heterogeneous and often null or endpoint-specific", and reported that no eligible outcomes trial has evaluated intravenous or intramuscular NAD+ for these indications at all⁴. A 2025 meta-analysis in adults averaging over 60 found NAD+ precursors did not improve muscle index, grip strength, gait speed or chair-stand time⁵. See NAD+ for longevity and do NAD+ peptides work.

None of that is a mark against System Labs specifically — it is the state of the category, and this board grades providers rather than the medicine. But a buyer who is paying $149 a month from the second month onward should know the outcomes being described have not been demonstrated.

Where it's weak, and who should skip it

Skip it if the first month is doing the work in your budget: run the arithmetic at $149 for NAD+ or $219 for sermorelin, because those are the numbers you live with. Skip it if you need to know the consultation cost before you start, since the landers do not state it. And skip it if you want to know which pharmacy fills your vial — Telos Rx names both of its dispensing pharmacies with street addresses, which no other provider here does.

Buy it if the menu is what you actually want. Four longevity routes under one intake, injection supplies and temperature-controlled shipping inside the price, and a published standing rate to plan against is a better starting position than most of this board offers.

The verdict, against the rubric

Our rubric scores five things out of fourteen: price transparency (4), a genuine longevity line (4), clinical oversight (2), pharmacy disclosure (2) and human support (2). System Labs takes the full four for its longevity line — NAD+ by two routes plus sermorelin by two more is as complete a longevity shelf as this board has — four for price transparency, because a standing monthly rate is published beside the promotional one with no prepay term attached, and two for human support, stated on every lander. It takes zero for clinical oversight, because whether the visit is inside the price is never stated, and zero for pharmacy, because no dispensing facility is named and no compounding standard is claimed. Ten out of fourteen: a B.

Both missing points are sentences, not systems. Publish whether the consult is included, and name the pharmacy or state its compounding standard, and System Labs would be at fourteen without changing a single term of the offer. Until then it sits mid-table with a strong menu and a page that will not finish the sentence. The full field is at our provider rankings, and the scoring is set out in how we grade.
