Preprint on grey peptide quality

Evaluation of Research Grade Peptides Marketed Directly to Consumers Reveals Extensive Variability in Purity and Measured Abundance

I am very aware of the forum's easter egg regarding the data source of this study. I have read the threads and seen the videos. I thought about writing to the authors, because bad original data screws the study as a whole, of course. But arguing on the base of anecdotal evidence or youtube videos doesn't cut it. ChatGPT tells me there is no scientific evidence.

What would you do?
How can it be that there is no external quality control on this lab?
Do they get away with it just because their customers don't have interest in putting legal attention to themselves?

The data they are using is not that bad, there are some issues, overall there is a lot of consistency there. I think the conclusions of the study are probably fair.

You have to keep in mind that our experience with Chinese vendors does not represent the general publics. This forum's participants are small slice if the general peptide market. There are probably a lot more people buying from scamers on Tik-Tok than from 'reputable' vendors.

We have access to high quality Chinese peptides. Most of the people buying these peptides will never do the work we have done to insure that. So yes, for your average person, the peptide market is a dangerous place with a lot of poor quality products and total fakes.

Without even reading the content, I have zero doubt the variable quality in the flood of "cheap" reconned product exists. I believe the variation to be great.

Enyola - thanks for posting this study. It makes for interesting reading and raises my awareness of the possible risks in the use of gray-market peptides, risks I was already reasonably aware of before taking the plunge, but the study provides some measurements of the scope of those risks. I don't understand though, what you're saying about the study. Can you clarify please? I'm not asking as a criticism but as a confession of my ignorance as a newcomer to this field.
