Cmsr Labs is a UK-based vendor operating in both retail and bulk markets, with shipping limited to the UK. The catalogue includes 11 peptides, with Janoshik-verified COAs available for 2 of them — 5 reports showing purity around 98.9%. Pricing is listed for most products. Community signal is minimal: a single customer-service mention with a negative lean, so there's little established texture on what the buying experience looks like.
