About Core Peptides

Core Peptides is a newer US-based peptide vendor founded in 2023 and operating out of Orlando, Florida. Despite being a recent entrant to the market, they have quickly built a large catalog that includes individual peptides as well as proprietary peptide blends. The company stands out for offering the widest range of payment options in the peptide vendor space, including credit cards, Venmo, Zelle, CashApp, cryptocurrency, and ACH transfers. They provide a 30-day refund guarantee and free Priority USPS shipping on orders over $200 with same-day processing. However, their short track record and occasional reports of fulfillment issues mean buyers should exercise additional caution.

Source's COA tier
third-party

Third-party testing is implied but COAs are not consistently included with all shipments. Testing documentation is only partially accessible on the website. observed

A COA describes one batch's purity. It is a document about a vial, not evidence about an effect, and it never grades a claim on this site — the grading rubric names what qualifies.

Linked names have a record here; the others we hold nothing on yet. A vendor listing a compound says nothing about the evidence for it.
