Why splitting your GH secretagogue dose works

Growth hormone is released in pulses, not a steady drip. When you stack a GHRH analog (CJC-1295 without DAC) with a GHRP (ipamorelin), you’re trying to trigger a clean, sharp pulse — and then get out of the way so the next one can happen naturally.

The half-life is the whole story

CJC-1295 (no DAC) has a half-life of roughly 30 minutes. That short clearance is a feature, not a bug: it means the compound is mostly gone within a couple of hours, so it doesn’t blunt your natural pulsatility. Ipamorelin is similar — a gentle, selective pulse with little cortisol or prolactin spillover.

If you take one large dose, you get one large pulse. If you split the same total across two doses — say morning and pre-bed — you get two pulses that each ride your body’s own rhythm. For most people chasing recovery and sleep quality, two moderate pulses beat one spike.

What the model shows you

In Autus, log both doses and the blood-level chart makes the difference obvious: two peaks instead of one, each returning to baseline before the next. You can drag the timing around and watch the curve change before you commit to a protocol. That’s the point — see the kinetics, then decide.

None of this is a prescription. It’s decision support. Bloodwork and a physician are still how you confirm a protocol is doing what you think.
