Merit Sciences is a research-compound seller for people who need batch documents and clear ordering terms before deciding. The maker says its catalog contains 31 research-use-only compounds, including NAD+, BPC-157/TB-500 stacks, semaglutide, tesamorelin, GHK-Cu, MOTS-c, and PT-141; it says every batch has a published certificate and outside-lab testing.

Is Merit Sciences legit?
Merit Sciences operates a U.S. storefront at meritsciences.com and publishes terms, shipping, returns, privacy, and contact pages. Its terms say purchases are for qualified researchers age 21 or older and for lawful in-vitro laboratory or scientific research. The products are not sold for human or veterinary use, and are not FDA-approved.
The maker says its vials are sealed, sterile, lyophilized material with a QR code that opens a public certificate-of-analysis library. It says ILS Laboratories performs identity, purity, heavy-metal, endotoxin, sterility, and fentanyl screening, with results tied to a lot. A practical buyer check is to match the vial lot number with the certificate before relying on a batch document.
“Licensed facility,” “ISO-certified,” and outside testing are the maker’s descriptions. The shipping and returns pages describe the facility as Dallas, while other page text says San Antonio. Ask support to clarify the fulfillment location if that detail matters to your research record.
What does Merit Sciences actually sell?
Merit markets research compounds, not supplements or prescription treatment. Its visible catalog examples and listed starting prices are below. These are product-page listings, not directions for use.
| Listed item | Amount shown | Listed price | Price per mg shown |
|---|---|---|---|
| RT3 | 10 mg | $99.99 | $10.00 |
| TZ2 | Not published | $74.99 | $7.50 |
| Wolverine: BPC-157 + TB-500 | 20 mg total | Not published | $5.00 |
| NAD+ | 500 mg | $84.99 | $0.17 |
The maker says it publishes 95 certificates and that its newest displayed BPC-157/TB-500 lot had 99.51% HPLC purity, tested August 1, 2026. If BPC-157 is the compound you are researching, this site’s BPC-157 science guide explains the emerging research question separately from any seller or vial.
Do peptides actually work?
That answer depends on the exact peptide, its formulation, route, dose, and the question being studied. A 2025 PubMed-indexed review describes BPC-157 as an experimental peptide and says orthopaedic literature on clinical use and outcomes in tendon, muscle, and cartilage injury remains scarce. That is why a product listing and a study of a compound are different things to keep separate.
For NAD+, the maker lists a 500 mg product. Cleveland Clinic’s NAD+ overview explains that NAD is involved in turning food into fuel and that many consumer products use precursors because NAD itself is difficult to absorb as a supplement. It also says long-term safety data for most NAD supplements are limited. That article concerns NAD supplements and precursors, not Merit’s research-use product.
There is no useful universal “top three peptides” list for a person. Start with the exact research question, then check the lot document, the compound’s published research, and the product’s permitted use. For a prescription-focused peptide program, compare the distinct care model in this site’s NEOLISE Renewal guide.
What are the downside and safety basics?
Merit’s own terms say its compounds are not intended to be administered, ingested, injected, applied, or otherwise introduced into a human or animal body. That makes them unsuitable for personal self-treatment decisions.
If you are considering any peptide, especially alongside medicines or with a current condition, ask a clinician first. The FDA’s March 2026 warning letter to another peptide seller explains why injectable products can create serious risks: they enter the body directly and can bypass defenses against toxins and microorganisms. That letter concerns Prime Sciences, not Merit Sciences, but it is useful context for the wider category.
For NAD-related products, Cleveland Clinic specifically says to speak with a healthcare provider before trying them if you have cancer or a history of cancer, advanced liver disease, are pregnant or breastfeeding, or are considering long-term high-dose use. Ask a clinician about any medicine you take rather than assuming a research compound is compatible with it.
How do you check a peptide seller before paying?
Use a simple document-first checklist. A seller’s claims matter most when you can connect them to the exact vial and order in front of you.
- Match the vial’s lot number with the published certificate.
- Check that the certificate names the exact compound and batch.
- Read the seller’s permitted-use terms before checkout.
- Confirm the item, vial count, price, shipping charge, and taxes in the checkout summary.
- Save the order confirmation, package photos, and outer label until the order is complete.
A community directory can be useful for finding vendors, but it says paid plans affect group order and some listed reviews are verified while others are not. Treat ratings as one input, not a replacement for lot-specific paperwork.
What does Merit Sciences cost and how does shipping work?
Prices shown above are as of October 14, 2026; check the checkout for today’s price. Merit says prices are in U.S. dollars, can change without notice, and do not include shipping unless stated, handling, or applicable taxes.

The seller says tracking appears in the shipping-confirmation email and may take up to 24 hours to populate with the carrier. Its public page also says orders placed on weekends or U.S. federal holidays are processed the next business day.
Can you cancel or get a refund?
Merit says an order can be cancelled for a full refund before it is picked and packed. Once it is marked “Picked” or “Shipped,” it says cancellation is no longer available.
Its returns policy says general change-of-mind returns are not accepted. For a wrong, missing, damaged, lost, or visibly defective shipment, the seller says to contact info@meritpeptides.com within seven days of the carrier’s confirmed delivery date. It asks for the order number, affected SKU, lot number, and photos of the issue. The seller says approved refunds go to the original payment method and typically post in three to 10 business days, depending on the bank or card issuer.
Do not send a vial back without written return authorization. Merit says unsolicited returns are refused and cannot be refunded.
Before you order
- Check today’s item price, shipping fee, and tax at checkout.
- Ask support to clarify the Dallas/San Antonio facility wording if it affects your records.
- Confirm the exact lot certificate is available for the compound and vial size you selected.
- Keep the packaging and order details in case you need to make a seven-day shipping claim.
- For personal health questions, take the product name and your medicine list to a clinician rather than relying on a research-use listing.
