I've brewed my own for a while.
I recently made a couple batches of Test E 400mg/ml
I used 3% BA, 15% BB, rest MCT oil.
Its a good brew.
However I just started my second cycle of it and 1 week in my sinus are swelling. I've got it for sure attributed to the homebrew. I don't think its a reaction to test itself.
Anyone heard of BA or BB causing my symptoms?
