Provider review · September 2026
System Labs runs a genuinely peptide-first storefront, but it names no pharmacy and publishes no state list, so a buyer cannot confirm eligibility until intake.
System Labs also sells 2 compounds this site boards without publishing a price for them: Glutathione and Sermorelin.

Visit System LabsSystem Labs sells NAD+, glutathione and sermorelin as injectables, plus GHK-Cu as a topical cream. Peptides are the business rather than a secondary line bolted onto something else.
That focus shows in the catalog's shape. A shopper comparing several peptides at once has more to work with here than at the single-compound sellers in this comparison.
Most listings show a struck-through renewal rate beside a first-month promotional rate. The number the eye lands on is the introductory one, and the ongoing cost sits above it.
Its GHK-Cu cream is the exception and the reason to trust the rest a little more. That line carries one flat monthly rate with no teaser and no strikethrough.
The NAD+ listing follows the promotional pattern. An introductory first month gives way to a higher standing rate, so budget from the standing rate rather than the headline.
The compounding pharmacy is described only as US-based. That phrase narrows nothing a buyer can check, and it means the facility filling the vial cannot be looked up.
The states System Labs ships to are not published anywhere on the site. A shopper in a restrictive state has no way to learn whether the company can serve them without starting an intake.
The site displays a LegitScript seal. A seal is a signal about a listing, not a substitute for naming the pharmacy or publishing a coverage map.
System Labs prices openly and sells a real peptide catalog, which is more than several competitors manage. It also asks a buyer to accept two blank spaces that other sellers fill in.
The unpublished state list is the sharper of the two. Price and pharmacy questions can be raised during a consult, but a shopper who is ineligible learns it only after handing over personal details.
System Labs is set head to head against Auren Rx and Rehydra+ Wellness on what each one publishes.
Trellis Vitality frames its program around body-composition tracking rather than scale weight, pairing NAD+, glutathione and tesamorelin with at-home biomarker panels and a 90-day re-test, and names its dispensing pharmacy, VialsRX in Houston, by address.

Visit Trellis VitalityThe company does not publish a state list anywhere on its site. That absence is the single biggest gap in its disclosure, and it means eligibility can only be settled by starting an intake. Ask before you provide payment details.
Usually not. Most listings pair a first-month promotional rate with a higher renewal rate shown struck through. Budget from the renewal figure. The GHK-Cu cream is the exception, priced flat with no promotion attached.
System Labs says only that its pharmacy is US-based. It never names the facility, so a buyer cannot check its licensure or inspection history. Sellers that name a pharmacy by address make that verification possible.
NAD+, glutathione and sermorelin as injectables, and GHK-Cu as a topical cream. That is the peptide menu, and it is broader than several single-compound sellers in this comparison.
