    2. Hi guys, I have stopped my cjc/ipa blend. I have used it in the first cycle and it was absolutely amazing. Now in the second cycle I keep get a heavy histamine reaction so I had to stop. What is the best thing to replace it with? I was thinking about HGH but I heard it takes months for the benefits.
