So im taking 400mg of Test Cypionate for 12 weeks and i have arimidex in case of gyno been taking it once a week everything seems ok. Im on week 3 i do notice my testicles shrinking just a tad bit and was wondering what should i take for pct and how long after week 12 should i take it? Im a bit confused on how pct works any input please! THanks in advance
