Quite old topic but I would like to add a summary of what I've tried to fix this and failed.
So my raws are +98% and my source is really high quality. Only problematic thing is this test e batch I have. I don't know what's that sub 2% contamination is but a few detailed to note: It was ordered during summer and arrived "waxxy, very hard, rock, slight yellow but marginally white brick"
A few batches of MCT carrier were done, Cold brewed ones, BB ranging from 8% to 22% and BA generally at 2% while 2 batches of 1.5% and 2.5% were done. TE dose 250,270,300,450mg/ml were tested separately in MCT. 250 & 270 cold brewed batch seemed to have a good amount of pip(and probably the least out of all, not far away from the heated[40c] batch but I did a few weeks on it just having golfballs in the injection spots for 4-5 days. Not a great experiance in the pip department there. But I was still partially functional at 250 & 270 and could lift my arm and stuff, training was not possible of the inflamed spots. the 300 is the latest batch being tested. I have done GSO this and heated it to around 200C for quite some time(a little color change so something did smoke for too long but whatever, can't be as bad as the 450 batch which I blowed with a torch and it's darker than the darkest red-tren you have ever seen, and yes it's not tren lol) , Cool! Let's see how that goes, Will report on that soon. Anyways general desc. of the pip is, Near rock solid, golfball, Dispersing in the injected muscle(not subq leak type of thing, basically spreads in the muscle and inflames) Painful to touch. Takes about a week to fully clean and at day 5 It's generally feeling fine and trainable. Filters used .22micron and everything else clean enough to not cause a infection from my experience.
Suggest anything else to try, Bored of brewing over 200ml of test batches and filtering by syringe filters cuz ain't worth setting up the vacuum...
And yes I'm aware it's a raw manufacture issue and I'm looking for ways to save it but switching to cyp is just the solution for sure or e batch in winter maybe
