System Labs

System Labs is a peptide-only service for sermorelin, NAD+, glutathione and a GHK-Cu foam. Almost every price is a half-price first month. The month-two price is printed right beside it.

Review by Molly Ward, goal-guide writer · Updated September 2026

The short version

System Labs is easy to read once you know the pattern. The big number is the first month, and the struck-through one is what you pay after. It names its pharmacy and prints a sermorelin schedule. It does not name the clinician who treats you. Its care and cancellation wording also contradict each other.

System Labs is a cash-pay online peptide service. You can buy sermorelin as an injection or a tablet under the tongue. NAD+ and glutathione each come as an injection or a nasal spray. There is also a GHK-Cu foam and a vitamin B12 shot. A custom peptide stack is sold too, but it names no compound. It sells no GLP-1s and no hormones.

What System Labs prescribes, by goal

Longevity

  • GlutathioneLegal to compound
    • Injection (compounded)From $149/mo
    • Nasal spray (compounded)From $169/mo
  • NAD+Legal to compound
    • Injection (compounded)From $149/mo
    • Nasal spray (compounded)From $119/mo

NAD+ nasal spray is one spray per nostril, once or twice daily. The NAD+ injection gives the monthly amount but no dose. Glutathione comes with no dose either; your clinician sets it. GHK-Cu is a 0.5% scalp foam for hair, though the catalog calls it a skin product.

Recovery

  • GHK-CuLegal to compound
    • Topical (compounded)From $109/mo
  • SermorelinLegal to compound
    • Injection (compounded)From $219/mo
    • Oral (compounded)From $159/mo

The same sermorelin is sold for body composition. The site says most people notice a change over three to six months. It cites no study for that.

Sleep

  • SermorelinLegal to compound
    • Injection (compounded)From $219/mo
    • Oral (compounded)From $159/mo

Sermorelin is taken once a day at night, 30 to 60 minutes before bed. Most people run five nights on and two off. The injection page prints no dose in micrograms. The tablet is one under your tongue before bed.

Each “From” figure is the seller’s own starting price, in the unit the seller states. Where a required fee or a package length changes what one month costs, the smaller line under it is our arithmetic, not a figure the seller prints. Compounded preparations are not FDA-approved.

Who prescribes

A licensed clinician

Your prescriber is a U.S.-licensed physician, nurse practitioner or physician assistant. The site says it limits how many patients each clinician takes. It names three doctors on its medical board. It does not name the clinician who treats you, or the group they work for.

You fill in a short online form, and a provider reviews it. The product pages say no appointment is needed and the provider reaches out by chat. The FAQ says you will be offered a telemedicine consultation after review. So which one you get is not clear. After that, the site says follow-ups and monitoring are built in.

Are labs required?

If your provider asks

Some treatments need baseline labs, the FAQ says. If so, your provider orders them. You can use a local lab, or System helps you book one. No lab price is printed.

What it claims, and what it cites

The benefit lines cite no study. Sermorelin is said to support deeper sleep. NAD+ spray users may feel more energy in the first week. The patient quotes are marked verified, but not whether anyone was paid.
