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

Pros

✓Pricing is published without an intake and stated as locked in with no hidden fees: Slim oral semaglutide at $299/month and TRT starting at $99/month (checked July 28, 2026)
✓Provider visits and shipping are free on all orders, so there is no separate consultation fee stacked on top
✓The TRT program includes a comprehensive lab test and a personalized plan, with a full refund if you do not qualify - so the assessment carries no financial risk
✓The compounded-medication disclosure is thorough and correctly worded, including the point that clinical data from FDA-approved drugs may not transfer to compounded versions
✓It explicitly disclaims any relationship with Novo Nordisk or Eli Lilly rather than trading on their brand names
✓An orally dissolving tablet is a genuine convenience for people who will not inject, and the formulation adds vitamin B6, which the site says is intended to reduce nausea
✓Replied to 100% of negative Trustpilot reviews
✓A dedicated safety page, pharmacy disclaimer and telehealth consent are all published and dated

Cons

✗At $299/month, Slim is one of the more expensive semaglutide options we cover - and it is compounded. For comparison, the FDA-approved oral semaglutide listed elsewhere on this site sits at $149/month, so you would be paying roughly double for a preparation the FDA has not reviewed
✗There is no published bioavailability data for this tablet. Approved oral semaglutide relies on an absorption enhancer (SNAC) plus a strict fasting-and-water protocol precisely because semaglutide is a peptide that is poorly absorbed by mouth. Without that data, there is no way to know how much drug a compounded orally dissolving tablet actually delivers
✗The weight-loss figures associated with semaglutide - roughly 14.9% of body weight over 68 weeks in the STEP-1 trial - come from weekly subcutaneous injections of the branded drug, not from a compounded oral tablet. Do not assume the results transfer
✗The FDA declared the semaglutide shortage resolved in early 2025, after which compounders were required to stop producing what amounts to a copy of an approved drug. Providers still selling compounded semaglutide generally argue their formulation is materially different. It is a fair question to put to the provider before paying
✗The refund policy covers dispensing errors, cancellation before filling, and shipping damage reported within 7 days. It does not cover simply not getting on with the treatment
✗Only 15 Trustpilot reviews, and no BBB profile, so there is very little independent evidence either way
✗No corporate entity, address or phone number appears anywhere on the site - support is a single email address
✗This offer is not available in Alabama, Alaska, Arkansas, California, Kentucky, Louisiana, Michigan, Mississippi, North Dakota, South Carolina, South Dakota or Wyoming
✗The brand voice leans heavily on bravado - 'MAN. GO.', 'You badass' - which sits oddly against prescribing a GLP-1 and testosterone, where the tone you want is clinical caution
✗Semaglutide is not suitable for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, and is not for use in pregnancy. Pancreatitis and gallbladder disease are recognised risks
