This has never happened before in 10 years. Maybe it's one of the things you suggested. I'll know soon if diluting with grapeseed oil makes a difference.
Hope it works out for you. If not I would look into what kind of oils your sponsor is using and maybe look for another sponsor that uses a different kind. There are many different variables that could be causing the pip, so the only way to try to remedy it is to try different methods used by members. Hell it can just be contaminated either at the lab or at home?? We will wait and see, Good luck
Glad to hear. Was going to mention that some guys even use B12 to dilute with. Like I said there are so many possibilities of pip. I still get it every now and then, even when using the same gear that caused no pain the week before.
I don't experience pip 99% of the time, but every now and then it happens. But IMO, it should never be crippling and keep you from moving or working out. There are so many great sponsors around who's oils are smooth as butter. Stick to the ones that work for you. Good Luck!!
