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

semaglutidetirzepatide

Pros

✓Offers FDA-approved brand-name options alongside compounded ones: the Wegovy pill, Wegovy injection and Zepbound injection are all listed at '$99 membership + medication cost'
✓Trustpilot rating of 4.4 from over 14,000 reviews, a far larger and better sample than most competitors in this category
✓Free dietitian visits and care coaching are advertised as included, and the program is listed as HSA/FSA eligible
✓Both injectable and daily dissolvable tablet formats are offered
✓Clinical services run through OpenLoop Health, an established nationwide clinician network
✓Full refund if a provider disqualifies you, and a full refund if you cancel within the first 72 hours before receiving any services
✓The terms state plainly that compounded GLP-1s are 'not FDA-approved or evaluated for safety, efficacy, or quality'
✓Published cancellation route by email or in-portal chat, with a named support address

Cons

✗The FDA issued MEDVi a warning letter on February 20, 2026 for misbranding its compounded semaglutide and tirzepatide, including for labelling vials as though MEDVi compounded them when it does not, and for 'same active ingredient as Wegovy' style claims the agency said imply FDA approval. This is the most serious regulatory finding against any provider on this site
✗We could not verify what the compounded plans actually cost. The affiliate landing page renders its own price placeholders unsubstituted - the page literally reads 'Only ${seminject_sale_price}' and 'Starting at ${semtab_sale_price}' in eight places
✗The only price that does render, $99, is a membership fee that explicitly excludes the medication cost, so it is not comparable to the all-in prices quoted by other providers
✗The same page claims 'No membership or hidden fees!' while listing '$99 Membership + Medication Cost' for the brand-name options a few lines below
✗Patient counts contradict each other on one page: 'Join 500,000+ MEDVi patients' at the top, '10,000+ Patients Agree' further down
✗The customer testimonials are word-for-word identical to those published on TrimRx's landing page under the label 'Verified TrimRX Customer', so at least one set is not what it claims to be
✗Monthly subscribers get no refund for the month in which they cancel or for any prior month - the policy states this in capitals
✗The user agreement imposes mandatory arbitration and waives class action and jury trial rights
✗Cancellation must reach the company at least 72 hours before the next billing date or the next charge still goes through
