If you are involved with peptides in any way, whether you are a researcher or a user, then you understand the importance of using pure and uncontaminated peptide. However, sometimes contamination is bound to happen, but the good news is that all the avenues through which contamination may happen, can all be blocked, and it is very possible to avoid contaminating the peptide in any way. Here is a brief look into how contamination may happen, and what you can do to stop the peptide from getting contaminated:
The source
As you already know, there is a good number of peptide vendors online, and not all of them are reputed to sell high quality peptides. The first step towards avoiding contamination is to ensure that you obtain your peptides from a credible source. Do your research, sift through the various vendors available, and select an authentic one who can provide good quality peptide, in good condition. Otherwise, dealing with poor vendors may just cause you to acquire contaminated peptides.
Poor handling of peptides
The second avenue, which contributes greatly to the contamination of peptides, is mishandling by the users. Normally, there are specific guidelines provided by the manufacturer, on how the substances ought to be handled for good results and longevity, but some users never see the sense in following such guidelines, and they end up contaminating the peptides throughout the process. For instance, it is always advised that you should only use the portion of the peptides you need, and the rest should always remain in storage.
Low quality storage
Lastly, peptides may get contaminated when they are stored in the wrong manner, or in the wrong place. Depending on the form in which the peptide is delivered, it will come with accompanying storage instructions, and these must be followed if contamination is to be avoided.
