I'm a self-acknowledged noob and certainly no authority on recovery, so take what I'm about to say with a grain of salt. I started doing cycles because I felt like I just simply could not grow on my own, and I really liked the results. Post-cycle recover for me wasn't friendly for a few weeks. I was kind of moody, disappointed in my drop in strength, etc. and just ITCHING to get back on test. Maybe there was something I could have done better.
But here's the point: when I finally did bounce back -- maybe 2 months after the end of my cycle -- I felt like I bounced back BETTER than I was before my cycle. I worked hard in the gym, pushed through even when I didn't want to go, and one day my girlfriend was like "are you on cycle again?" and I said no, why? And she tells me she's noticing a difference in my composition and like I was making progress. And I was, in a way I had never made before the cycle.
So why that is, who knows. For some reason, I do feel my test production is higher than it was before but I have nothing scientific to back that up. The only guess I have is that maybe my use of HCG throughout the cycle kept my nuts healthy and somehow tweaked my body into naturally producing more test. I actually believe I've read an hCG study that suggests that this is possible (something around 40% natural improvement). I can try to find it for you. I don't remember if this is right, it's just what sticks in my head, but I remember the article and I can see if I'm mistaken or if there's something to it.
