Not back to normal in a couple days, but I noticed a big change yes. I ran about 1000iu EOD for 10 days, I have 2000iu amps. I ran that with liquidex (which I had been running for about 2 weeks @ .5mg), while on the HCG I finished off with 1mg ED, seemed to work great. I am on 20N/50C ED currently, woke up with a woody at friggin 3AM after being in bed for only 2 hours, and my sex drive was affected previously so I feel very close to a full recovery although I am trying to make sure this time.
I am actually making slight gains in the gym too, so for me that is a great sign instead of this incredible shrinky dink shit after my previous cycles finished and ended up counting for basically nothing. I feel like I got shut down so damn hard on cycle that I just stagnated, very slow gains in every department (strength and size), but I refused to simply up the dose to overcome that I knew something was wrong. A couple weeks into the last cycle my nads started shrinking, and I didn't get the massive sex drive increase that I had last time.
Anyhow, long story short, I will run HCG religiously while on because it greatly enhanced my recovery, night and day difference. 500iu twice a week or E4D/E5D sounds good.
