GHRH/GHRP IM v SQ ?

So, I'm doing a shooting in mid-sleep cycle (I wake up on purpose for this) and immediately when I get into my car in gym parking lot, both IM. I figure this helps get the stuff to the right place as fast as possible which should help avoid blood sugar concerns. However, I saw a reputable TRT doc on a youtube channel compare it to the flush one gets from niacin...with a negative tone and body language when comparing IM to SQ (he seemed to favor sq). Anybody have any info about this?

SQ just releases the peptide more slowly over time. The IM will peak into the blood stream and dissipate. I like SQ over IM for peptides and HGH. It seems to work better. Don't have any clinical proof, just years of use experience.
