I had 30g Test E raw powder from Landmarkchem. First 15g went into 40ml, no problem, had a good 3 months on that vial. Six-nine months later I brew again, same everything, but changed the oil, not GFO, but something else organic wife had in the kitchen. Two pins, both legs swollen, fever, not good. I was disappointed, thinking I have to throw away the vial. Ah, after the first bad pip I heated the vial in pan, cleaned, no help. Three months forward, I put the vial in the microwave, heated up good over a minute. Color changed a little bit more brownish. First pin less than a ml, no swelling. Second pin three days later. 1.5ml felt immediately good, first pin of a cycle rush in blood. In 12 days oily forehead, pumping in calves while riding bike. Test kicked in, confirmed. I just wanted to share the experience.
