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

Medications

continuous glucose monitoring

Pros

✓A genuinely different approach: a continuous glucose monitor plus an app that tells you how your own body responds to specific foods, rather than a prescription subscription
✓Published plan pricing: $127/month on the longest plan, $150/month on the mid plan and $225/month on the shortest, each discounted from a higher list price
✓Two CGM sensors per month are included in every plan
✓HSA/FSA eligible, which matters at these prices
✓Registered dietitian support is included, with in-app chat and the option of a face-to-face session
✓A 30-day results guarantee: if you do not learn something new about how your body loses weight, a senior Signos coach audits your data free, described as a $250 value
✓One membership covers the sensors, the app, the coaching and the behaviour-change programme instead of stacking separate subscriptions
✓It pairs sensibly with a GLP-1 rather than competing with one, and the company states medication costs are included in the Signos programme where applicable
✓Stress and sleep tracking are built in alongside glucose

Cons

✗This is not a GLP-1 prescribing service in the way the rest of this site is. If you came here for a semaglutide prescription, Signos is a different kind of product
✗The cheapest per-month rate requires the longest commitment, and six-month plans ship in three-month bundles
✗CGM-guided eating for weight loss in people without diabetes has far weaker evidence behind it than GLP-1 medication
✗HSA/FSA eligibility is qualified - "Possibly, but it depends on your HSA/FSA provider" - and Signos states it is not responsible for reimbursement, with the cancellation policy still applying if your provider refuses
✗The results guarantee pays out in a free data audit, not money back
✗Outcome claims reflect individual Signos patient experiences rather than published clinical studies, which the company discloses
✗Not suitable if you are on insulin without speaking to your own clinician first, which the signup flow asks you to confirm
