Core Peptides - anyone tried them?

Stumbled on Core Peptides while browsing around and they seem legit but I barely see any real reviews from actual customers. A lot of their stuff looks good on paper but that only goes so far. Has anyone here actually placed an order? Would love to know how the quality was, if you tested anything yourself, and how the whole shipping/packaging situation went. Also what payment methods did they accept when you ordered? I'm mainly trying to find a reliable domestic source so if you've compared them to others I'd be curious to hear that too. Thanks in advance.
