CJC-1295 (No DAC)

CJC-1295 without DAC, also sold as Mod GRF 1-29, is a modified fragment of growth hormone releasing hormone, the signal your hypothalamus sends to tell your pituitary to release growth hormone. Natural GHRH is destroyed within minutes; four amino acid substitutions here slow that down enough to be useful without making it last for days.

The distinction from injecting growth hormone itself is the point. HGH floods your system with a constant level of hormone and your pituitary, seeing no reason to bother, largely stops producing its own. CJC-1295 asks the pituitary to do its job, so the pulse pattern your body is built around is preserved and nothing shuts down.

The No DAC part matters. The DAC version binds albumin and keeps GHRH signalling elevated for days, which sounds better and mostly is not: continuous elevation is exactly the pattern the body does not use, and it blunts the pulses that do the work. No DAC gives a pulse of a couple of hours and then stops.

On its own it works. Paired with a ghrelin receptor agonist like Ipamorelin it works considerably better, because the two press different buttons in the same room.

Your hypothalamus releases GHRH, which tells the pituitary to release growth hormone. That is one of two main levers on GH output; the other is ghrelin, acting on a separate receptor. Natural GHRH lasts a couple of minutes before enzymes destroy it.

CJC-1295 No DAC is GHRH's first 29 amino acids, the active portion, with four substitutions that resist that degradation. The result survives around 30 minutes, which is long enough to produce a solid pulse of GH release and short enough that it stops afterwards.

The reason it stacks with Ipamorelin or GHRP-6 rather than competing is anatomical. GHRH tells the pituitary to release; ghrelin agonists both stimulate release and suppress somatostatin, the brake on GH output. Pressing the accelerator and releasing the brake together produces a substantially larger pulse than either alone, and this is well demonstrated rather than theoretical.

The No DAC choice is deliberate. The DAC version keeps signalling elevated for six days or more, which produces a constant GH bleed rather than pulses. Your body evolved around pulses, and the receptors that respond to GH downregulate under constant exposure. Short and sharp beats long and flat.

The most common side effects are water retention, tingling or numbness in the hands, and injection site redness. All are dose-related and largely disappear at 100 mcg per injection.

Hunger increase is common, especially when stacked with GHRP-6. With Ipamorelin it is much milder.

Because it raises your own GH rather than supplying it, there is no suppression of your own production and no post-cycle protocol. Stop and you return to baseline rather than below it.

Growth hormone raises blood sugar and can reduce insulin sensitivity over time. Anyone diabetic or pre-diabetic should speak to a doctor before running any GH secretagogue.

Do not use during pregnancy or breastfeeding, or with an active cancer diagnosis: growth hormone and IGF-1 promote cell growth generally. Speak to a doctor first if you take prescription medication or have any existing condition.
