Hey, I would like to ask about the product as with that specific group meaning Peptides in generel. My question is about the production of the peptides itself because HPLC purity is relative and vague atleast I believe considering this group. Though to be said I dont doubt your quality at all but I would really really like to know how you handle residues like TFA or PFAS in generel as it is known that certain synthesis like SPPS may leave residues due to useage of trifluoroacetic acid for example.
Best Regards
Hello
In order to answer your question, I would need to submit an inquiry directly to the laboratory. Before I do that, I would like to better understand the reason behind your question — I hope you don't mind me asking.
Are you specifically concerned about the purification process and residual compounds in our peptides, or are you conducting broader research and comparing practices across different companies? Have you already received any answers on this topic from other manufacturers or suppliers?
The reason I ask is that, from time to time, we encounter questions that customers ask because they have read somewhere that a particular topic is important, rather than because they have a specific practical concern. In most cases, such questions do not provide much practical value to the end user.
A good example would be questions about heavy metal testing of finished products. In many cases, people ask about this after reading an article, watching a video, seeing a forum discussion, or receiving a recommendation from AI. However, from a practical standpoint, the only way to be completely certain that a specific product contains no heavy metals is to test the exact sample you intend to use.
The reality is that virtually no company in this industry tests every batch of every finished product for heavy metals. Such testing is typically performed on the raw materials by the manufacturer or supplier before production, after which certificates of analysis are issued. Of course, this assumes that the company sources its raw materials from official and reputable suppliers, as we do.
So before I contact the laboratory, I would simply like to better understand the practical purpose of your question. That will help me determine whether requesting additional information is worthwhile and what type of answer would actually be useful to you.
I hope you understand what I mean.
