My balls didn’t shrink until after 7 years of running gear and 1 year on trt. Enclomiphene though seems to be putting some size back in my babies! But then they shrink up again lol. Honestly this is the first time I’ve ever heard someone guessing gear is fake because of ball shrinkage lol. I think you’re good my friend, look at your lifts, strength, and BLOODWORK. Running gear costs money, the whole lifestyle of it, if you can’t afford to get blood tests then maybe it’s time to reevaluate if this is a good idea
