Has anyone on trt or a cycle taken igf1 lr3 and had their testicles come back to life? I've been on trt for a year and got levels up to 600 but was suffering from shrinking balls... so I cycled trt with pct after each cycle. I started igf1 lr3 last week and and within a couple of doses my testicles have rebounded while on trt. I never expected this but it's happened. Is there a mechanism for igf1 and leydig cells?
