cheap
Per-mg pricing beats most places I've checked. Vials arrived sealed, no issues.

been ordering for years
Been buying from Core for about four years now. Consistency is the main reason I stick around. Packaging could be better but the product itself is reliable.

Reliable
Been ordering from Core for about four years now. Same consistent quality every time, packaging always intact. Shipping has gotten noticeably faster recently. No complaints worth mentioning.

third reorder
Third order from Core Peptides and the vials look identical to my last batch. Consistency is why I keep coming back.

COA actually matched third-party
Sent their tirzepatide COA to an independent lab on a hunch. Numbers came back at 98.4%, basically matching what Core Peptides published. Hard to argue with that kind of transparency. Reordering.

Consistent quality across multiple orders
Been ordering from Core Peptides since around early last year. Purity reports always come through with each batch, which is why I keep coming back. Packaging is solid — lyophilized product arrives intact every time. Not perfect, but reliable enough that I don't look elsewhere.

Absolutely phenomenal customer service
Absolutely phenomenal customer service. The delivery system misplaced the package and they immediately followed through and sent a whole new order for me. The team is very responsive and shipping times are very fast. Great price and quality products. Could not recommend enough

good price, fast shipping
Watched the site for a while before buying and grabbed it during a 20% off code stack. Per-mg price came in noticeably under what I'd been paying elsewhere, even after shipping. Vials arrived double-bagged with cold pack still firm. Knocked one star because tracking didn't update until day three, but no real complaints.
