Does splitting a CJC/Ipa dose AM and PM actually beat a single bedtime shot?

Bit of a contrarian question this, because everyone bangs on about sleep being the prime GH window and bedtime dosing being the holy grail. But I keep wondering if a single dose before bed is leaving pulses on the table during the day.

If you run CJC-1295 no DAC with ipa at say 100/100 twice a day (AM fasted and PM pre-bed), does that give you a meaningfully different recovery or sleep feel compared to just doing both pins together right before bed? Ngl I have only run the twice daily version and my sleep on it felt solid, but I never did a proper apples to apples comparison with bedtime only.

Curious whether anyone here has actually run both setups back to back and noticed the difference, or if the second daytime pulse is just adding cost and pin fatigue without much real upside. I get the theory of mimicking natural pulsatility, I just want to know if people actually feel it in practice or if it's one of those things that sounds clever but does not really move the needle.

  • elle_z: Honestly the am dose is the one I notice most, not the pm one. I sleep fine either way, but the daytime pulse is where my recovery and training output seem to shift. I ran bedtime only for a few weeks first and was honestly underwhelmed, then added the morning shot fasted around week 6 and the difference was pretty obvious within like 10 days. Soreness between sessions dropped, gym output felt more consistent. Split dose is more pins and yeah the cost adds up lah, but for me it wasn't subtle.
  • fasted_scientist: Interesting, that kinda tracks with what I've heard from a couple of people. The morning pulse thing makes sense on paper since endogenous GH blunts with age and food intake, so you're catching a window that's basically closed otherwise. Genuine question though, how were you measuring that difference? Like is it "I felt less sore" or actual output tracking? Both are valid I just want to know what we're working with before I read too much into it.
