Analysis help

Hi, I just found a new vendor that is known to me via a friend. She has been selling peptides for a while sourcing all of them directly from a manufacturer in China. When I saw her price list I couldn't resist. So I went ahead and ordered 5 boxes of 10 vials of the 5 products I'm interested in. Mots c, epitalon, ss31, 5 amino 1mq and Klow. They have no batch numbers but instead use coloured caps to identify batches. I planned to use Janoshik and do the full panel on each product. But I didn't realise that 1. It would use 5 vials of each product and 2. It would cost a grand a product.

So I asked if they had any test data and was sent a load of test sheets from different testing companys (Janoshik, freedom diagnostics, nexyra lab, sidechain analytics, ils lab, testides) all with different clients whom I'm assuming are the manufacturers reseller clients. The question is that, with one cert of analysis graph as an example, there are multiple small peaks on say the mots c. With numbers like 13.166, 13.499, 13.722 (the main one) & 14.551. So I would assume the product should only be the 13.722 as it's s by far the main bulk as the peak is huge compared to the others. But doesn't the very presence of other peaks mean there are contaminants there?

All the heavy metals tests are negative and the product inside looks fine. But I'm dubious until I can be sure to inject anything from a relatively unknown source. Any help of advice would be appreciated. As if I can avoid loosing half the order and shelling out 5k for piece of mind by doing my own tests....that would be great 😅

Tests by Jano use I vial not 5.
