Just wanted to chime in as I've had similar issues as you. For low E2 symptoms especially brain fog try 25mg DHEA and 10mg Pregnenolone. I get the nutri cost brand off Amazon, does the trick just as good if not better than Dbol/HCG for me and without the oral toxicity. If that amount isn't enough double the dose split through the day.
Currently running 500 test cyp, 600 primo ( Axle ) and 300 Tren A. Slight pip but nothing indicative of contamination. I am using the 100mg/ML in GSO. I've found heating the vials up with a blow dryer for about 5 minutes or so substantially lessens my PIP, all my vials look black from the heat labels. Lol
