Quick take
Core Peptides is an Orlando, Florida supplier with a large catalog, a published address and phone number, and a certificate for every lot from an A2LA-accredited laboratory. The certificates answer two questions, identity and purity, and leave the rest unanswered. Prices sit in the middle of the market and shipping is quick and cheap within the US.
Who this supplier suits
Core Peptides fits a US lab that wants a lot-level certificate from an accredited outside lab, a supplier it can phone, and a plain refund window. The ~104-item catalog covers single vials (BPC-157, TB-500, Ipamorelin, CJC-1295 DAC, Sermorelin, Tesamorelin, Semax, Selank, MOTS-C), blends, and topical cosmetic peptides such as GHK-Cu. No GLP-class products are sold, which simplifies intake for some labs.
It is not for international buyers, for labs that need endotoxin or sterility data on the certificate, or for anyone who needs the payment methods confirmed before reaching checkout.
Testing in plain English
Every product page links a PDF from Vanguard Laboratory in Olympia, Washington, which holds A2LA accreditation (the certificate cites A2LA certificate #6377.01.01). The BPC-157 5mg document for lot C74112 reports purity above 99.80% by HPLC-UV/VIS, dated 7/22/2026. The files open without a login and carry a lot number, which lets you match them to the label.
The limitation is scope. The certificates cover identity and purity by HPLC only. There is no mass spectrometry confirmation, no endotoxin result and no sterility result. If your lab needs those, you will have to run them yourself or choose a supplier whose certificates include them.
Prices and shipping
Mid-tier. BPC-157 runs from $52 for 5mg to $97 for 10mg. We did not record further prices at our check.
Orders placed before 4pm Eastern, Monday to Friday, ship the same business day. USPS Priority Mail is $12 with delivery in 1 to 3 business days and is free on orders of $200 or more. UPS Overnight is a flat $49 for next-business-day delivery. Shipping is to US addresses only.
Service, returns and payments
A full contact set is published: street address, phone and email. The research-use-only disclaimer is present. The site states a founding year of 2019; peptideprotocolwiki.com lists 2023, and the same wiki along with outliyr.com reports undelivered orders and fulfilment problems. We could not verify those third-party reports either way.
Refunds may be requested up to 30 days after an order is placed and settle in 2 to 3 business days; unshipped orders can be cancelled by emailing support@corepeptides.com. No purity guarantee is stated.
Payment is by card, but the only indication is a Mastercard logo under a Now Accepting heading, so confirm other cards before ordering. The Trustpilot profile has been removed by Trustpilot for going against its guidelines.
Final word
For a US lab that needs an accredited-lab certificate per lot and a supplier with a real address, Core Peptides is a reasonable first order. Read the PDF for your lot, understand that it stops at HPLC purity, and keep the 30-day refund window in mind.

Is Core Peptides legit?
The company publishes a street address, a phone number, a stated founding year of 2019 and lot-level certificates from an accredited lab, which is more than most. Its Trustpilot profile has been removed by Trustpilot, and third-party wikis report fulfilment issues and a 2023 founding date; we could not verify those reports.
