System Labs Review

System Labs is a peptide and longevity shop, not a GLP-1 weight-loss clinic

Let's set expectations up front, because the category label can mislead you. System Labs — legally System Laboratories, Inc. — is a US telehealth platform built around peptide and longevity injectables: NAD+, glutathione, sermorelin, and a MIC+B12 lipotropic shot. It does not publish semaglutide or tirzepatide on its product grid. So if you came here for a Wegovy or Zepbound alternative, this is not that service. The only item with any real weight-loss relevance is the MIC+B12 injection, and even that is a supporting-cast product, not a proven fat-loss drug. Read this review as a look at where System Labs fits in a broader wellness shortlist — not as a head-to-head with the big GLP-1 telehealth names.

What you can actually buy here

The catalog is short and specific, which is honestly refreshing. Four core products show up on the homepage:

• MIC+B12 lipotropic injection — the weight-loss-adjacent one, a blend of methionine, inositol, choline and vitamin B12 marketed for energy and metabolism support
• NAD+ — a longevity and cellular-energy injectable
• Glutathione — an antioxidant injectable popular in the wellness and recovery crowd
• Sermorelin — a growth-hormone-releasing peptide that overlaps with the men's-health and anti-aging world more than with weight loss

All of it is compounded — meaning these are made-to-order by a pharmacy, not FDA-approved brand-name drugs. That's normal for this corner of telehealth, but it's worth knowing you're buying compounded preparations, not products that went through the FDA approval process.

How the pricing really works

System Labs runs a simple flat monthly model per product rather than a dose-laddered GLP-1 plan. The MIC+B12 shot sits at the low end of the lineup — a high two-figure monthly rate — while NAD+ and glutathione land higher, right around the broader category median of $149 a month. Most products also carry an introductory rate for the first month, so your initial charge is usually lower than the ongoing one. Because System Labs doesn't publish a single standard 'membership' price the way a GLP-1 clinic does, treat each product as its own subscription and confirm the current rate at checkout before you commit. There's no big consult fee buried in the funnel that we could find, but the per-product structure means stacking two or three items adds up faster than a single all-in monthly plan would.

The MIC+B12 question — does the weight-loss product earn its place?

Be clear-eyed here. MIC+B12 'lipotropic' shots are a long-running wellness staple, but the evidence that they drive meaningful weight loss on their own is thin to nonexistent. The B12 can genuinely help with energy if you're low, and some people like the routine of a weekly injection as part of a broader plan. But if your goal is real, measurable fat loss, this is not a substitute for a GLP-1 medication or a structured program. The fairest way to think about MIC+B12 from System Labs is as an adjunct — something you might add alongside diet, training, or an actual weight-loss medication from another provider, not the engine of your results.

What genuinely sets System Labs apart

Two things stand out in the verified record. First, it carries a LegitScript verification seal, which is a meaningful trust signal in a space full of gray-market peptide sellers — LegitScript vets that an operation is a legitimate, lawful healthcare merchant. Second, it states it's HIPAA-compliant and dispenses through licensed US compounding pharmacies. For a peptide platform, that combination puts it ahead of the no-name sources people find on social media. The niche focus is also a differentiator: rather than being yet another GLP-1 reseller, System Labs has carved out the NAD+/sermorelin/longevity lane, which is a genuinely different shopper than the typical weight-loss patient.

Where the trust story has gaps

Our verification confidence here is moderate, not high, and you should know why. As of the last live check, the pharmacy partner was described only as a 'US-based compounding pharmacy' and was not actually named on the site — so you can't independently confirm which facility is making your injectables or whether it holds PCAB accreditation. State availability isn't publicly disclosed either, so you won't know if System Labs ships to you until you start the intake. There's no PCAB or BBB information surfaced on the homepage. None of this is disqualifying, and there are no FDA warnings on file against System Labs — but the unnamed pharmacy and undisclosed state coverage are exactly the kind of details a fully transparent provider would put in plain sight. Ask directly who compounds your product before you pay.

Who should consider it — and who should skip it

• Consider it if: you specifically want NAD+, glutathione, sermorelin, or a B12 lipotropic shot from a LegitScript-verified, HIPAA-compliant US source, and you value a focused peptide catalog over a sprawling pharmacy menu
• Skip it if: you want a real GLP-1 weight-loss program — System Labs doesn't publicly sell semaglutide or tirzepatide, and the MIC+B12 shot won't replace one
• Skip it if: pharmacy transparency is a dealbreaker for you, since the compounding partner and state coverage aren't published

Bottom line

System Labs is a credible, narrowly-focused peptide and longevity platform with a real trust signal in its LegitScript verification — but it's miscast as a weight-loss service. Its only weight-adjacent product, the MIC+B12 shot, is a mild adjunct with weak standalone fat-loss evidence, and the platform's two soft spots (an unnamed pharmacy and undisclosed state coverage) keep our confidence at moderate rather than high. If you're shopping for NAD+ or sermorelin, it's a reasonable, legitimate option worth comparing. If you're shopping for GLP-1 weight loss, look at a dedicated provider instead and judge any of these picks against our scoring methodology.
