No slin. I was told not before bed due to biggest natural Gh spike within 2 hours of sleep. Not after waking for same reason. Not around workout time for same again. I'm only taking 2 iu's per day currently, so only once per day.
If I wasn't on slin, I'd take it at bedtime. You get your natural release your first 2 hours of deep sleep, the injected gh doesn't kick in for a few hours ( I believe it's around 4 hours) after injected. That way you get your natural and injected gh and while you're sleeping. There is a debate as to that theory, from what I've read, more people seem to like bedtime injections.
