Only used HCG before PCT and not during my run. Let me say that I stopped all AAS use at 41, so it was a few years before we had the boys. That being said I had a test level of 198 at the age of 46 and very little sex drive. So there is a price, I also have a medical issue that contributed to my low test sow it's hard to pinpoint the exact reason for such a low test level.
