Why the Pulse Matters

Endogenous growth hormone is released in pulses, primarily during deep sleep. Continuous elevation (as seen with exogenous GH) suppresses the body's own release and carries a different risk profile. The CJC-1295 + Ipamorelin combination is researched specifically because it preserves pulsatile release.

Both peptides share a short (~30 minute) half-life, which is deliberate: a compound that clears quickly produces a discrete spike rather than a sustained plateau. The pairing also exploits the well-documented synergy between GHRH-pathway and ghrelin-pathway stimulation — the combined pulse is larger than the sum of either alone. This post walks through the physiology of GH pulsing and why members interested in longevity tend to favor pulse-preserving approaches over continuous replacement.
