If you are looking for where to buy Merit Sciences peptides, the seller directs orders through meritsciences.com. Merit Sciences says its catalog is for qualified researchers age 21 or older and for lawful laboratory and scientific research only, not for human or veterinary use.

Where is Merit Sciences sold?
Merit Sciences presents meritsciences.com as its direct ordering site. Its About page says researchers can browse the catalog and order direct without an account. The seller lists 31 compounds in stock, including RT3, TZ2, NAD+, semaglutide, tesamorelin, GHK-Cu, MOTS-c and PT-141.
That matters if you arrived after seeing an ad or a social post. Use the exact spelling, meritsciences.com, rather than following a look-alike product listing. Merit says each vial label has a QR code that opens its public certificate-of-analysis library, so you can compare the compound and lot information before making a decision.
Can you buy these peptides for personal use?
No. Merit Sciences labels every compound for research use only. Its terms say buyers represent that they are qualified researchers, laboratory professionals, or licensed practitioners ordering for a legitimate research purpose. The products are not drugs, dietary supplements, cosmetics, or medical devices, and the seller says they must not be introduced into a human or animal body.
This is an important distinction when you are researching pain, recovery, skin, energy, or weight concerns. A 2025 review indexed by PubMed describes the limited orthopaedic literature on clinical outcomes for injectable therapeutic peptides and notes the need to keep up with their safety, ethical, and legal profiles. For a plain-language look at the broader topic, see Peptides and Inflammation.
What does Merit Sciences charge?
Prices shown on October 14, 2026 are listed below. Prices and catalog availability can change, so check today’s price on the company’s site before you order.
| Listed compound | Amount shown | Listed price | Price per mg shown |
|---|---|---|---|
| RT3 | 10 mg | $99.99 | $10.00/mg |

| NAD+ | 500 mg | $84.99 | $0.17/mg |
A three-month total depends on the compound, amount, and research plan, so there is no single three-month price to rely on. The listed figures above are a useful starting point for checking the cost of the exact item you are considering.
How shipping works
Merit Sciences says it ships within the United States only and does not ship to P.O. boxes, freight forwarders, or APO/FPO addresses. The company says orders are picked, packed, and handed to a carrier within one to two business days, with standard ground delivery taking three to five business days after dispatch.
Standard shipping is free on orders of $100 or more, according to the seller. Expedited shipping is available at checkout for an added fee. Merit says it sends tracking by email and uses USPS or UPS, selected by destination and service level.
How do you avoid a look-alike seller?
Keep this simple. Start at the exact Merit Sciences domain, check that the catalog describes the item as research use only, and compare the vial’s QR-linked certificate with the compound and lot information you expect. Merit says its certificates include testing information such as identity, HPLC purity, heavy metals, sterility, endotoxin, and fentanyl screening.
Do not let a familiar peptide name turn into a shortcut around the product’s stated purpose. The seller says its catalog is for laboratory research, not personal use. If your goal is to understand how a research finding differs from a consumer claim, Emerging Research explains how to read early findings without turning them into a promise.
What happens if your order is damaged or wrong?
Merit Sciences says it does not accept general change-of-mind returns for these sealed research materials. It says a replacement or refund may be available for a wrong item, transit damage, a missing item, a lost shipment, or a defective vial when you contact it within seven days of the carrier’s confirmed delivery date.
The returns page says to email info@meritpeptides.com from the address used for the order, with the order number, affected SKU and lot number, plus requested photos. It also says orders can be cancelled for a full refund before they are picked and packed; after that status changes, cancellation is no longer available.
