I'm going to admit to something very stupid. When I was about 25, I was doing a lot of growth, trying different protocols etc. One occasion I was doing nighttime shots. I preload most SubQ injectables, and somehow got my GH and liquid clen mixed up in the night. Instead of 10iu gh, I think I shot something ridiculous like 2000mcg clen subq. It took about 10 mins to realise something was seriously wrong with me, my heart went nuts and I was sweating really badly. Luckily I had propranolol to hand and it helped, but still, that experience really scared the shit out of me. I told my Mum who I was staying with at the time that I must have had a fever, as I was red and sweating badly for more than a day after that.
