My wife kept sending me articles about synthetic fabrics and testosterone. I kept ignoring her. Then my doctor mentioned my T levels were lower than they should be for my age and suggested looking at endocrine disruptors as a first step. Started with underwear. Three months later, levels came back up, energy is better, lifts are better. Had to admit she was right. That was a painful conversation 😅

I'll be honest — my drive had been low for about a year. Blamed work, stress, age. My girlfriend noticed before I did and started researching. She found stuff about synthetic fabrics disrupting hormones and basically told me to change my underwear or she'd do it for me lol. Switched to these. Few weeks later things noticeably improved. She's happy. I'm happy. Should've listened sooner 😏

I've had chafing my whole adult life. Tried every brand. Assumed it was just my body. My wife finally convinced me to try these after months of me complaining. Put them on at 7am, walked around all day at work, got home at 7pm — zero chafing. First time in literally years. I felt stupid for waiting so long honestly 😅
