      @beachfun We have a second kit of this we are using for some other degridation tests. Lio'd on a windowsill, in the fridge and in the glove box of my truck. Check back in 3 months.

        I just watched a video that said the true way to test if a product is what it actually is sold as is to have it tested with Liquid Chromatography-Mass Spectrometer (LC-MS) to actually tell if it actually the correct peptide. I thought that is what a purity test covered, but looking at this image above, I guess I am wrong.

        What vendors are tested like that and what testing labs are actually using this? I see Freedom might be, if I am reading that right.

        I apologies in advance, new to COA process and trying to learn more on it.

        video that I randomly came across:

          Looks like Freedom uses it. I need to research this more.

              @randy Do you think kits are ever mixed?
              I have the mind set that it’s just business and people in china are doing the right thing… I still pin it anyway

                  @Randy I should have clarified. Different patches in one kit.

                    It could happen but there's typically a different cap color for every batch.

                    At the end of the day they could be putting caps on from batches made months apart

                      Actually a fee vendors on TG have been saying they have been using the same cap colors on different batches and no batch numbers. Makes it really hard to track what is wjat for testing purposes
