I was not trying to ignore your question. You guys have to remember that even though it may seem like i am here all the time, the reality is that between owning multiple medical practices and some of the community work i do, i have very little time. I do try to be here as much as possible in between patients etc.
To answer your question, all the studies you posted are very valid. GH does negate the effect of GHRH. It will not affect the single injection of the day but it will affect all subsequent ones. For example, if you wake up at 7am and inject 100/100peps and wait 30min and then inject 2iu of GH, you are fine. By the time you have injected the GH, your own internal GH has pretty much peaked anyway from the peptide injection. The issue is when 3 hours later you want to inject peptides again, the GH injection is just peaking and will prevent further GH release. As a matter of fact, synthetic GH lasts for a good 8-12 hours in the system so it will be inhibitory during that time.
I have never used GH and peps for this reason and also for the reason that the whole idea of using peptides is to use your own GH and not worry about antibodies etc. By the time you start incorporating 2-3iu of GH daily on top of your peps, then you might as well take the money from peps and just use GH all by itself. The only way to test this though would be to do exactly what i said above.
Inject 100/100 GRF/GHRP
Inject 2iu of GH 30min later
get serum GH checked at 40min mark
inject 100/100 GRF/GHRP 3hours later
and then re-check serum GH again 40min later.
If you see a major blunting of GH release on the seccond serum GH you will know that presence of GH does indeed blung the release of GH.
