What Time to Inject HGH?

Test study on humans http://ajpendo.physiology.org/content/276/6/E1009.full

I have seen several threads on this in the past, but am wondering if any of you have changed your protocol in the last couple years. Now I am looking more for advice on 1x a day injections, not split protocols, and not IV level.

From everything I have see there are four schools of thought:

  1. Morning Injections first thing. Wait 1 hr to eat prior.

  2. First thing before sleep.

  3. 6 hours prior to sleep in order to fall within the 6-12 hour life window to get your own pulse naturally.

  4. Slit injections for higher IU dose users, some AM and PM, some AM and PWO.

Any thoughts on the subject?

So far this approach makes the most sense to me.

"I know a lot of people say to use GH first thing in the morning. I’ve been doing a lot of research and came across this study that was actually done on humans, most are on rats. http://jcem.endojournals.org/cgi/content/full/85/2/601 According to this study, it would make most sence to inject your GH right befor bed. If you don’t get a chance to read it all, it states that once you inject GH it take about 4-6 hours to fully realse in the body, and can shut your natual production of GH down for up to 24 hours.

If this is correct, then injecting right before bed and letting your body produce it’s own production, about 1-2 hours into deep sleep, and then benefit from the injected GH 2-4 hours after your body releases it’s own would make the most sence. Since your bodies production would be shut down for around 24 hours, hopefully by the time you go to bed the next day your body would still realses it’s own GH and the sequence would continue.

Your thoughts?"

surely if you have loads of exogenous hGH you don’t need your natural production?

Noted, Im not sure how many IU I make a night, but even if it was any, I would hate to toss it out if I could have both. I want my cake and eat it too.

yeah that’s fair enough. I don’t know anything about GH, I’m just thinking out loud
