The Physiological Truth About Pulsatile vs Tonic GH Signaling
Here's the honest answer: the peptide industry markets convenience, but your endocrine system doesn't care about convenience. It cares about signal pattern. Sustained GH elevation is not how your body evolved to regulate growth, metabolism, and tissue repair.

- Here's the honest answer: the peptide industry markets convenience, but your endocrine system doesn't care about convenience. It cares about signal pattern. Sustained GH elevation is not how your body evolved to regulate growth, metabolism, and tissue repair. Natural GH secretion is pulsatile for a reason: pulsatile signaling allows receptor resensitisation between pulses, prevents chronic negative feedback suppression, and creates differential gene expression patterns in target tissues compared to tonic exposure. Studies comparing pulsatile GH administration (mimicking natural secretion) versus continuous infusion (tonic elevation) show pulsatile delivery produces superior anabolic outcomes, stronger IGF-1 induction in hepatic tissue, and better preservation of insulin sensitivity.
- CJC-1295 no DAC works because it respects that physiology. Modified DAC versions prioritise dosing convenience at the cost of introducing a non-physiological signaling pattern. The 6–8 day half-life creates low-level tonic GHRH receptor occupancy that your pituitary interprets as sustained stimulation. Somatostatin (GHIH) release increases in response. GHRH receptor density downregulates. GH pulse amplitude flattens over weeks. The peptide still works. But progressively less effectively than it did in week one. The no-DAC version avoids this entirely. Dose it correctly and the 50th injection triggers the same pituitary response as the first.
