okay so I've been lurking on this thread for a bit while eating lunch and finally have to jump in because this is genuinely one of the better mechanistic discussions I've seen on this topic in a while and I have Thoughts, lol

n00b is 100% correct here and IronGut's last reply basically confirmed it too. bella's intuition about the GHRH/GHRP functional division was not wrong, like at all. I want to pile on to this point specifically because I went through almost the exact same intellectual journey a few years back when I first started logging my own GH peptide experiments and the thing that helped me most was someone telling me "your model of the mechanism is basically right, the protocol people sold you FROM that model is the part that doesn't hold up" - those are really different criticisms and it matters for how you continue building your understanding.
the "pump priming" mental model isn't bro-science, it's actually a fairly elegant way to describe what's happening at the somatotroph level. the issue is the leap to "therefore I need a 5-10 minute head start on the GHRH" which implies the receptor-level signaling takes longer to develop than it actually does. which dr_peptide covered well honestly.

this mirrors my own logging experience pretty closely. I ran CJC no-dac and ipamorelin for about four months at one point tracking sleep quality through my Oura ring scores (yes I know, consumer device, not exactly a metabolic chamber, I'm aware, lol) and I spent the first six weeks doing the staggered approach because I'd read the same forums everyone else has apparently read, and then switched to simultaneous for the next ten weeks and the difference in my tracked metrics was genuinely negligible. like within normal night-to-night variance territory. not a controlled trial obviously but I'm pretty meticulous about logging and I noted it at the time.
what DID make a noticeable difference in my experience, and I don't think anyone has touched on this yet in this thread - was the fasting window. like getting at least 2.5-3 hours of genuine fasting before the pre-bed dose was way more impactful on my subjective recovery feeling than any timing nuance between the two peptides. the insulin/GH antagonism is real and in my logs it showed up more clearly than basically any other variable I was tracking. bella if you're not already dialing that in, that's probably where I'd focus attention before worrying about whether your GHRH is hitting 7 minutes or 0 minutes before your ipamorelin.

T_Ortega said this and it needs to be underlined twice and put in bold and maybe tattooed somewhere. I was SO impatient during my first connective tissue focused run. I had a hip flexor thing that had been annoying me for like eight months and I went into the stack expecting noticeable change in like two to three weeks because that's the timeline people imply when they talk about it online and then week three felt basically the same and I almost stopped. week seven was when something genuinely shifted. week ten I was like oh. OH. so yeah. patience is not optional with this, it's basically part of the protocol.
on the ipamorelin vs GHRP-2 question that came up - I've run both and I lean hard toward ipamorelin for any context involving active recovery or body comp optimization for the exact reasons T_Ortega and IronGut described. the cortisol increase from GHRP-2 isn't massive but when you're trying to build a hormonal environment that's conducive to healing and favorable body composition changes, adding a cortisol variable that you don't need is just... why? ipamorelin gives you a clean selective pulse and that selectivity is genuinely useful when you're trying to assess what's working. I've also personally found the hunger stimulation from GHRP-2 to be an annoying variable when I'm trying to manage food timing around doses, ipamorelin is just so much less complicated in day to day life.
anyway long reply as usual, sorry bella, but I hope some of this is useful. your questions were good and your framework was more solid than some of the thread responses implied. the source critique was fair but it was aimed at the 10x number, not at your underlying mechanistic thinking, which was honestly pretty on point for someone coming at this fresh.
