I am 45 years old and started taking Humatrope 2ius 1 week ago. I am doing a 7 day a week regimen but I have noticed that in the last couple of days I have had issues with erectile dysfunction. Is this related to my HGH injections. I have been under some severe stress lately. My fiance and I broke up about 2 weeks ago so I am wondering if the ED is related to the stress or the HGH?
