I would agree anxiety could cause an elevated HR.But this was over 200 and I owned a heart monitor for many years.I got it under control,thought it was over....then suddenly HR took off again.Could be some kind of issue there but illustrates the power of the master hormone.humalog is the WORST for that and does not put on muscle like the longer lasting versions. For all the shots you would need to do in a day to put on actual mass, it is complete shit.
If... YOu had a HUGE carb meal as you claim and a small dose of slin... Bro, it IMPOSSIBLE to feel those effects you claim right away.
If you're too scared of something, just don't do it. Your mind is playing tricks on you.
