COA actually held up
I'll be honest — I order from multiple vendors and I always cross-check the COA against third-party HPLC data when I can. Half the time the purity numbers don't survive that comparison. With Peptides, the last two orders I ran through an independent lab and the reported 98.2% and 97.9% purity figures came back within half a percent of what their documentation claimed. That's not something I take lightly. I've been burned before by vendors who post generic COAs that clearly aren't batch-specific, so I started asking Peptides direct questions about lot numbers before placing my third order. They responded same day with batch-specific documentation that matched the vials I received. Shipping was also faster than expected — lyophilized product arrived well within the cold-pack window and reconstituted cleanly with bac water, no cloudiness. Pricing is competitive without being suspiciously cheap, which honestly would have made me more skeptical. I'm not ready to say they're perfect after three orders, but three for three is a decent track record.
