Medications
NAD+sermorelinglutathioneMIC + B12GHK-Cu
Pros
- ✓Prices are published openly for every product, with the renewal rate shown alongside the introductory one: NAD+ $89 first month then $149, sermorelin $109 then $219, glutathione $79 then $149, oral sermorelin $79 then $159, MIC + B12 $89/mo and GHK-Cu cream $109/mo (checked July 28, 2026)
- ✓Three delivery formats for NAD+ - injection, nasal spray and liposomal liquid - so needle-free options exist
- ✓Products are described as American made and third-party tested
- ✓The intake is short and a licensed provider reviews it before anything ships, with free 2-day shipping
- ✓No insurance required and no membership fee stacked on top of the product price
Cons
- ✗This is not a GLP-1 weight loss service. System Labs sells no semaglutide, no tirzepatide and no GLP-1 of any kind - the words do not appear anywhere on its site. If you are shopping for weight loss medication, this provider cannot supply it
- ✗We could not find any statement that the compounded peptides are not FDA-approved. That disclosure is standard across this category and its absence is the single biggest gap on the site
- ✗There is no refund or cancellation policy published at all - only a privacy policy and terms page
- ✗No independent review signal exists: no Trustpilot profile, no BBB file, and no rating displayed on site
- ✗Introductory pricing roughly doubles at renewal on most products, and the renewal price is the one you will pay for the rest of the course
- ✗Sermorelin, GHK-Cu and high-dose NAD+ have limited published human trial evidence for the benefits implied - 'perform 10 years younger' style claims are not supported by the kind of trials that back GLP-1 medications
- ✗No published phone number, support hours or physical address
- ✗The 'up to 1600mg' NAD+ potency claim is presented as an advantage without any evidence that higher doses produce better outcomes
