How did OP keep his palms callous free is the real mystery here lol. Even 6 months of serious lifting should thicken anyone’s palms.It reqs heating up , hair dryer, hot water, microwave for around 5 seconds and swirl, repeat until gone . It’s called crashed. By the way, with hands and fingers like yours are you sure you should be using testosterone? Your hands are like ones off a moisturiser tv advert
Maybe those lifting gloves actually work.
