GH Release Pattern: Pulsatile vs Sustained
Your pituitary naturally releases growth hormone in 6-12 discrete pulses per day, with the largest surge occurring during slow-wave sleep. Between pulses, GH drops to near-zero. This on-off pattern is not a flaw in human biology. It is the signal itself. Pulsa

- Your pituitary naturally releases growth hormone in 6-12 discrete pulses per day, with the largest surge occurring during slow-wave sleep. Between pulses, GH drops to near-zero. This on-off pattern is not a flaw in human biology. It is the signal itself.
- Pulsatile GH release activates lipolysis (fat breakdown) more effectively than continuous exposure. A study in GH-deficient adults found that pulsatile GH administration produced greater fat oxidation and protein synthesis than continuous infusion at the same total dose (Giustina & Veldhuis, Endocr Rev, 1998). The liver's GH receptors also appear to respond more robustly to pulse patterns, producing more IGF-1 per unit of GH when signaling arrives in bursts (Tannenbaum et al., Endocrinology, 2003).
- CJC-1295 without DAC preserves this pulse architecture. Each injection creates a clean spike, and somatostatin resets the system between doses. Stack it with ipamorelin and you get a pulse 3-5x larger than either peptide alone, because ipamorelin works through the ghrelin receptor (GHSR) while Mod GRF 1-29 works through GHRH receptor. Two doors into the same room.
- CJC-1295 with DAC overrides the pulse architecture. The pituitary receives continuous GHRH stimulation, which dampens somatostatin cycling and produces a "GH plateau" rather than spikes. Total GH output over 24 hours may be equal or higher, but the pattern is different. Some users prefer this for convenience. Others find that the sustained pattern produces more water retention and fewer of the discrete benefits associated with sharp pulses.
