This is the first time that I've used hcg/hmg during a pct..... and I"m amazed at how well its working! I've only done 4 injects of 1000ius/75ius, and my balls are almost back to size, I can't believe how fast this stuff works. And my libido is great, just like when I was running test at 1g/week. I'm definitely going to include them in any upcoming pct in the future.
