protocol_deep_dive on something I’ve been running for about 11 months and finally have enough data to say something useful about. the standard ipa protocol you see posted is 200-300mcg subq, 2-3x/day, with one of those doses pre-bed. the morning and post-workout shots get defended on the grounds that you’re hitting the GH pulse window multiple times. ymmv but I think that framing is wrong. the nocturnal GH pulse during slow-wave sleep is the biggest endogenous release of the day by a wide margin. it’s not one of several roughly equivalent pulses, it dwarfs the daytime ones. so a pre-bed ipa shot is amplifying the largest existing pulse, while a morning shot is creating a smaller pulse against a baseline that’s already low because cortisol is doing its thing. the part that matters and that nobody on the protocol posts talks about: if your sleep architecture is compromised (alcohol the night before, late meal, screens, perimenopausal night sweats, whatever), the pre-bed shot is also compromised, because there’s no slow-wave wave to amplify. I logged this against my own sleep tracker for about 4 months and the lifts and recovery markers track sleep quality more than they track dose timing. so my read: - one pre-bed dose, 200-300mcg, 60-90 min before lights out, on an empty stomach (3+ hrs since food)
- skip the morning shot, it’s spending money on a small pulse
- if sleep is genuinely bad that night, the shot didn’t do what you think it did, don’t blame the compound the ipamorelin half-life is ~2 hrs, so timing relative to sleep onset matters more than people frame it. imo this is where most people are leaving the actual use on the table.
The nocturnal pulse framing is solid and I mostly agree with the pre-bed priority, but “skip the morning shot, it’s spending money on a small pulse” undersells what the post-workout window actually does. GH secretion post-resistance training isn’t a baseline daytime blip, it’s a meaningful secondary pulse, and ipa timed there is amplifying something real, not firing into nothing. Whether that’s worth the cost is a different question, but framing it as equivalent to a random AM shot collapses a relevant distinction.
fair point on the post-workout pulse, I overcollapsed there. the resistance-trained GH bump is real and amplifying it isn’t the same shape of waste as a random AM shot. where I’d still push is on magnitude: even a meaningful post-workout pulse is a fraction of the nocturnal slow-wave release, so the cost-per-mcg math still lands lopsided toward pre-bed for most people running a single-vial budget. if someone’s already dosing pre-bed and has headroom, the post-workout shot is the next logical add, not the morning one. that’s the distinction I should’ve drawn instead of lumping them.
the cost-per-mcg math is fair if you’re treating all pre-bed conditions as equal, but that’s the part I’d actually push on. the framing assumes the pre-bed shot is reliably hitting what you’re optimizing for, and from what I logged last year it isn’t, not consistently. my eight months of ipa tracked pretty tightly to the same conclusion as your OP – slow-wave quality as the multiplier, not dose – which means the pre-bed shot has a meaningful variance range depending on the night. a post-workout shot hits a pulse that’s more predictable in magnitude and timing bc it’s exercise-induced, not sleep-stage-dependent. you don’t have to worry about whether you got enough deep sleep to make it land. so “single-vial budget, prioritize pre-bed” is solid advice for most people and I’m not arguing that. the thing I’d refine is the “next logical add” framing for post-workout. fwiw it might be the first logical add if someone has consistently bad sleep quality, bc then the pre-bed shot is the variable one, not the amplifier they think it is. the magnitude difference is real, I’m just not sure magnitude beats consistency as the relevant variable for everybody running this.
edit: typo
one angle that doesn’t get aired much in these threads: the IGF-1 readout people use to “prove” the protocol is working is a much noisier signal than the once-a-quarter draw makes it look. intra-individual CV on serum IGF-1 sits around 10-15% even on stable dosing, and it drifts with protein intake the prior 48 hours, acute illness, and (relevant here) sleep debt the week of the draw. so if you’re A/B’ing one-shot vs two-shot on quarterly bloods, the noise floor is wide enough to swallow a real effect either way. the older GHRH-analog literature (sermorelin work from the 90s, mostly) ran into the same problem and ended up leaning on overnight integrated GH sampling rather than morning IGF-1, which nobody is doing at home for obvious reasons. worth knowing what the lab number can and can’t tell you.
