Okay, so HCG is a tool to be used carefully, not a miracle cure. It helps maintain testicular function and can make PCT easier, but it's not a replacement for a SERM. Thanks for all the great info.
It's an excellent tool for experienced users on long cycles, but for a simple 12-week Test E cycle, a SERM-only PCT is often sufficient.
HCG is part of a comprehensive harm reduction strategy, not a shortcut.
HCG for too long can desensitize the Leydig cells which basically means your body stops responding as well. So the trick is moderate, steady dosing during the cycle *not megadoses* and then transitioning into your PCT smoothly.
