People report this with HPLC tested stuff that is proven to be of the same purity/concentration too, "feels" reports are notoriously unreliable in medicine.

My company makes HPLCs.
Yes, they can 'prove' what is in something to the limits of the physics.
However, the human in the loop is quite frail for most operators. In that, these very fancy and very expensive instruments are mostly run by high school grads and serviced by field engineers with a huge backlog.
For a first time one off test of something's composition, I'd go for at least 3 companies and preferably you have a history with them. This stuff is terribly complicated and misinterpretation is shockingly common. If the tech hasn't used the standards before then your at the mercy of fate.
Like, we have 5 (!) places on the home screen that do the exact same function of ending a run because when we try to consolidate it to just 1, our customers freak out and can't find where the button went to. Granted they pay $100k+ per instrument plus service plan, so we add it back in no question ( and this is life critical equipment in many cases), but I hope that shows how embedded to routine these operators get.
Janoshik is the primary company people use here, and their business is basically entirely peptides and anabolic steroids, and the GLP-1 stuff exploded their business from gym bros to soccer moms everywhere. https://janoshik.com/
But they basically test the same 12ish compounds day in and day out, with another couple of dozen making up the remainder. They don't have most of the worries that you are referring to - first time for a tech running a specific set of standards, limited experience interpreting them, etc., and when people head to head their results against different labs, they are consistent.
What she presented to me was that more than one of her patients taking unregulated GLP-1s simply stopped losing weight, and in an unexpected way. I have no idea how many patients this was. My doctor is rad and very much pro-GLP-1s and pro-preventative-care. This is ultimately an anecdote.
There's a well known plateau effect with GLP-1s where the body adjusts to the changes in caloric intake and the medication itself so that weight loss levels off and stops after a period of time. It could be that but it's hard to tell with 2nd hand info.
