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

semaglutidetirzepatideestradiol

Pros

✓It states the full cost structure openly in the headline rather than the footnotes: 'Alloy Weight Care is $99/month plus the cost of medication. Medication starting at $70/month', so the realistic entry is about $169/month (checked July 28, 2026)
✓That transparency is the opposite of the pattern we see elsewhere, where a membership fee is disclosed only in small print beneath the price
✓Care comes from menopause-specialised doctors - 'menopause experts, not generalists' - which matters because midlife weight gain is often hormonally driven
✓Unlimited doctor messaging is included, with dosing adjusted over time
✓Menopause hormone therapy is FDA-approved rather than compounded, unlike several women's hormone providers we review
✓Roughly 4,000 Trustpilot reviews averaging 4.3
✓Free delivery and HSA/FSA eligibility across the range
✓A $50 discount on the first month of care is offered to new customers

Cons

✗The $99/month care fee buys access, not medication - your real monthly cost is the fee plus medication starting at $70, and rising with dose and product
✗The GLP-1 line is compounded and therefore not FDA-approved, even though the menopause hormone therapy is
✗Aimed specifically at midlife women, so it is not the right fit outside that group
✗No published phone number - support runs through your account
✗GLP-1 medications are not suitable for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, or during pregnancy
