I asked, because it looks more like a work of a 1st year student than senior/professor. No offense to you, but offense to the person who did those tests. One should be ashamed of producing something like that, especially in senior position.
My opinion will be taken as biased around here, so I'll let others chime in, however the 'demo' shown shows less than undergrad level of knowledge in HPLC.
When @Turkish Pharmacy asked questions before, for the lab, I already had suspicion about their abilities, however, it is now confirmed.
There is pretty much no separation happening in the last image shown, it's more of a guessing game - pretty much anybody can see that it's impossible to determine the area under the curve precisely by a single look:

But more importantly the K Prime is around 0.3
Absolute minimum, often insufficient (with deca most certainly!) is 1.
FDA minimum is 2.
For deca I'd say 3+ is acceptable.

Simply put, the results produced are invalid, unfortunately.

Jack off, I meant, Jano, you’re an extremely knowledgeable person when it comes to these test results and graphs, to bad you’re a crooked arrow that don’t fly right. You could have been THE man around here.
