Seriously, I just got a new batch of a peptide for research and the COA is just... minimal. Like, barely any detail. I know we are all doing research here, but it feels like some suppliers just slap a label on it and call it a day. I mean, I want to trust what I am getting. My experiments depend on it. When the purity numbers are vague or missing, it makes me question everything. It is not like I can just run my own full spectrum analysis in my garage. Anyone else feel this way? Or am I just being overly critical? It is just a hassle when you are trying to maintain consistency across multiple trials and the starting material is a question mark.
