A dual-pathway growth-hormone protocol pairing CJC-1295 (no DAC) with Ipamorelin for pulsatile GH release that mimics natural physiology.
01About this protocol
Hulk is a growth-hormone protocol, built on the CJC-1295 (no DAC) and Ipamorelin combination. It pairs a GHRH-receptor analog with a selective GH secretagogue so the two act through complementary receptor mechanisms rather than a single pathway.
The no-DAC form of CJC-1295 — also known as Mod GRF 1-29 — is used specifically for its short half-life. That produces pulsatile GH release rather than a sustained elevation, keeping the signal closer to the body’s own rhythm.
02Why these together
- CJC-1295 (no DAC) stimulates GHRH receptors on pituitary somatotrophs, triggering cAMP/PKA-mediated GH synthesis, with a short 30-minute to ~2-hour half-life.
- Ipamorelin selectively stimulates GH release through the ghrelin (GHS) receptor without raising cortisol, ACTH, or prolactin.
- Because both have comparably short half-lives, together they produce synergistic, pulsatile GH spikes that mimic natural physiology instead of a flat elevation.
- Timing follows the pulse: once daily before bed is convenient, while twice daily (AM + PM) better mimics natural pulsatility and allows roughly six hours for GHS-receptor resensitization between doses.
03Components
GHRH analog (Mod GRF 1-29) — pulsatile GH release
IPASelective GH secretagogue — ghrelin (GHS-R1a) agonist
In research the pair is handled either as a single blended vial (a 10 mg blend of 5 mg CJC-1295 + 5 mg Ipamorelin) or as two separate 5 mg vials, reconstituted with bacteriostatic water under sterile technique. Equal amounts of each are used for complementary effect — separate vials allow individual tolerance testing, while a blend trades that flexibility for convenience. Reputable sources supply a certificate of analysis (COA) with purity testing.
04Supporting foundation
Growth-hormone research is sensitive to timing around meals and insulin: food — especially carbohydrate and fat — blunts the GH response, so fasted timing is a common experimental variable. Protein and amino-acid availability provide the raw material for any adaptation.
