CJC-1295 + Ipamorelin: The Classic GH Stack, Explained

If you have looked into peptides for muscle, recovery, or anti-aging for more than five minutes, you have seen CJC-1295 + Ipamorelin recommended. It is the default answer, the "just start here" stack. But almost nobody explains why these two specifically, or what they actually do together.

So here it is, start to finish. New to stacking? Read What Is a Peptide Stack? first.

What is the CJC-1295 + Ipamorelin stack?

It is two growth hormone peptides run together. Both nudge your body to release more of its own growth hormone (GH), but they do it through two different doors, which is exactly why they are paired.

Run alone, each one works okay. Run together, they produce a bigger, cleaner GH release than either does solo. That synergy is the whole reason this combo became the standard.

How does it work?

Here is the two-door thing in plain terms:

CJC-1295 mimics a signal called GHRH. Think of it as raising the overall amount of GH your body is willing to put out. It sets the stage.

Ipamorelin mimics a different signal (ghrelin) and triggers an actual GH pulse. It pulls the trigger.

One raises the ceiling, the other fires the release. Together you get a stronger pulse than either alone. Ipamorelin is popular specifically because it is "clean" - it triggers GH without dragging up hunger, cortisol, or prolactin the way some older compounds in its class do.

Why these two and not others?

Textbook complementary stacking. A GHRH peptide plus a GH-releasing peptide cover two different mechanisms that amplify each other. Stacking two peptides that pull the same lever would be redundant. These pull different levers that work together. That is what a good stack looks like.

Dosing: what people run

Commonly cited community figures (not a prescription - start low and see how you respond):

A typical dose is around 100 mcg of each, taken together, anywhere from once to a few times a day. Many beginners start with a single dose before bed.

Timing is the part that matters most. These are usually taken on an empty stomach, often right before bed, because food (especially carbs and fat) blunts the GH pulse you are paying for. The pre-bed dose also rides your natural overnight GH release.

CJC-1295 with or without DAC is a common question. The "no DAC" version (sometimes called Mod GRF 1-29) gives a sharper, shorter pulse and is what most people pair with ipamorelin for that timed-pulse effect. The DAC version stays active much longer. For the classic pulsing stack, no-DAC is the usual pick.

What to expect

Realistic version: this is a slow, supportive stack, not a dramatic one. People report better sleep first (often within a week or two), then gradual improvements in recovery, body composition, and skin over a couple months.

It is not steroids. It will not blow you up. What it does is raise your own GH output to support the basics - sleep, recovery, leaner composition over time. Manage expectations and judge it over months.

Who is it for?

This is the standard entry point for anyone new to GH peptides. Two compounds, well understood, predictable. If you are building toward a muscle-growth stack, this is usually the core you build around.

The part that gets messy

Two peptides, often dosed together, sometimes multiple times a day, with timing that actually matters and reconstitution math on top. That is a lot to track off memory.

Our stack builder handles it - drop in CJC-1295 and ipamorelin, set your doses, and it does the reconstitution math and lays out the timing in one place. The dose calculator tells you exactly how much to draw.

Then save it to My Stuff. Free, one click, and your exact protocol is there next time instead of in your head. Build it once, run it whenever.

Quick FAQ

How long until CJC-1295 + Ipamorelin works? Sleep improvements often come first, within a week or two. Recovery and body composition changes take a couple of months. It is a slow build.

What are the side effects? The common ones are mild: water retention, tingling or numbness in the hands, a head-rush feeling, and increased hunger for some. Ipamorelin is chosen partly because it keeps these low.

Should I use CJC-1295 with or without DAC? For the classic timed-pulse stack with ipamorelin, most people use the no-DAC version for a sharper pulse.

How long do you run it? People commonly run it in cycles of several months. There is no single rule - longer runs are common since the effects are gradual.
