Peptides Lab UK prices vs the other shops I've checked

Peptides Lab UK (peptideslabuk.com) keeps popping up in comparisons, so I had a look. They list 11 products, prices are posted openly, there are COA documents, and they say UK location. Okay, that's a start. What I actually want to know: are those COAs real third-party HPLC/MS reports, and do the batch/lot numbers on them match what's currently being sold? How often do they get refreshed when a batch changes, and can a buyer request the COA for a specific lot before ordering? Then the basics — do those 11 products reflect actual current stock, and are out-of-stock or discontinued items clearly marked? And on the published prices, are they inclusive? Comparing them against a couple of other UK suppliers and just trying to figure out if they're worth a look. Anyone here used them?
