First HGH Cycle Questions

Hey guys I’ve learned so much about a gh cycle. I’m planning on doing it in the next 6 months. I only have one question that I just can’t seem to find an answer too… The question is when should I take my injections I’m starting with 4iu a day. I know to take it first thing in the morning but my question is when should I take the second injection I work till 5 pm then train from 530pm till about 630-700 pm I’ve heard never before bed cuz my body is producing its own peaked gh and I also heard not before workout cuz it could mess with the intensity of the workout.

Any help with this would be great cuz I really wanna know what I’m doing before I start a 6-8 month cycle!! Any other help or tips on a first gh cycle would be greatly appreciated. Thanks
