FWIW I have 4 year old vials of Test made with Miglyol MCT (Dragon Pharma) that are still water clear, and other MCT based test that went from a very faint tint to much more yellow in the same storage conditions, over the same period. I don’t have peroxide test strips yet, but I’m fairly certain that’s oxidation. I won’t be doing a PIP test, since keeping HS-CRP almost supraphysiologcally low (0.3) has made such profound improvement in overall “wellbeing” I’m not going to risk it. If I had known this sooner I would’ve pursued anti-inflammation extremes long ago.
Too bad DP seems to have stopped making oils at the beginning of the year….
When I started with “bathtub” gear from the “guy at the gym”, my GF would comment on how I practically radiated body heat. Now I know what that was, and how damaging systemic inflammation is.
