I wish that, if you are going to join in my aspect of the discussion, please read all of my comments carefully before replying so that what we add is informative and helpful.
I never said the gear gave me an infection. I said that the doctor told me that cellulitis could only be caused by bacteria, or more specifically "flora". I didn't say I believed that the doctor was correct, just that I wanted to take into consideration every factor so I could Understand what happened and why, and avoid it in the future so I could use the gear with minimal if any issue.
As far as understanding what exactly is behind the reaction, I've yet to get a definitive explanation. I get that something in it is irritating to the body, and more so to some than others, with dosage playing a big role in it. Pharmacom did reply reassuring the sterility of their product, which I never really doubted unless the product I received was counterfeit.
I already explained my reasons and methods of using the testE500. In hindsight I wish I had just stuck with the testC250 as it's worked fine with zero PIP. But it is what it is.
I would advise anyone who reads this in the future to not dose in the same spot until all swelling/soreness is entirely gone, and dilute with either a lower doses oil or filtered sterile GSO or similar substance.
If anyone can add helpful information concerning the actual cause of irritation I would appreciate it, but beyond that I'm putting this behind me now as the original reaction is almost 1/4 healed and I pinned lower on my right glute Sunday night mixing 1/4ml TestE500 with 1/4ml testc250 and have virtually no PIP which seems to confirm my belief that this all originated from using this new stuff and injecting in the same spot while it was still sore.
