01

What is CJC-1295 with DAC?

Plain language first. The technical label stays, but it never stands alone.

Overview

It raises your own growth hormone steadily from a single weekly or twice-weekly shot.

The technical version

CJC-1295 with DAC is a long-acting GHRH analog, a copy of the hormone that tells your body to make growth hormone, with a molecular anchor ('DAC') that keeps it working for days.

What it's used for

A long-acting shot that keeps growth hormone raised for days, used to build muscle, burn fat, recover, and sleep better. You inject it only once or twice a week.

02

How does CJC-1295 with DAC work?

What it does in the body, and where.

CJC-1295 copies GHRH, the hormone that tells your pituitary to make growth hormone. The DAC version carries a molecular anchor that keeps it circulating for days rather than minutes.

  1. 01
    It copies your growth hormone releasing hormone
    Prompting the pituitary from upstream, rather than supplying growth hormone directly.
  2. 02
    The DAC anchor binds it to a blood protein
    That is what stretches its working life from minutes to roughly a week, and it is the only difference from the no-DAC version.
  3. 03
    A raised baseline, not a pulse
    Because it stays active for days, it lifts your overall level rather than producing the natural pulses. Whether that matters is genuinely debated.
Duration of action
ACTIVE ABOUT 6 TO 8 DAYSactive about 6 to 8 days
The 2 to 10-fold growth hormone figures come from this version only.
03

What else is it used for?

Each group carries its own evidence level.

Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

Growth hormone release

Research only
  • Human trialIn a small early human study, one injection raised growth hormone 2 to 10-fold for more than six days.
  • Human trialIGF-1, the hormone growth hormone works through, rose 1.5 to 3-fold for 9 to 11 days.
  • Human trialAfter repeated doses, IGF-1 stayed above baseline for up to 28 days.
  • No dataIt was never approved, development stopped, and it is banned in drug-tested sport.
Often left out

The 2 to 10-fold growth hormone numbers come from this DAC version specifically. They are routinely misapplied to the no-DAC version, which behaves completely differently.

How much, and do you cycle it?

The range, and whether you take breaks.

1 up to 2 mg per dose (start low, increase slowly), 1-2x per week. Commonly cycled, usually 8 to 12 weeks on and 4 off Community practice

Commonly cycled 8 to 12 weeks on and 4 off, and no study has tested that. The argument for it is that this version holds growth hormone at a raised baseline rather than restoring pulses. Worth knowing that when GHRH itself was infused continuously for 14 days in people, the pituitary did not run down. So the tolerance case for cycling this one is an inference from related drugs, not something anyone has measured in it.

How do I dose and price it?

Enter your vial and your dose. Pick a mix. We show the draw and the cost.

The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

How do you store it?

Before mixing, and after.

Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.

Unmixed lyophilized CJC-1295 with DAC keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

08

What are the side effects and cautions?

Known cautions and warnings for this compound.
Handling note

Can cause a histamine flush: temporary flushing, itching, or welts near the injection, usually mild and short-lived. Injecting slowly helps. If it spreads, or you get facial or throat swelling or trouble breathing, treat it as a reaction and get help immediately.

Solubility, computed: 33% charged residues, 43% hydrophobic. Water usually sufficient.

A first-pass rule from peptide manufacturers' guidance. It does not account for disulfide bridges, salt form or how the powder was dried, and it predicts what should be easy rather than what will happen in your vial.

Who should avoid it

Check these before anything else.
  • Active cancer
  • Pregnancy
  • Banned in drug-tested sport

Stop and get help

These are emergencies. Seek care.
  • Spreading hives, face or throat swelling, or trouble breathing
  • New lumps or masses

Common effects

Expected, and usually mild.
  • Flushing, itching, or a welt near the injection, which is a histamine effect rather than an allergy
  • Water retention
  • Tingling in the hands
  • Tiredness
  • Because it lasts for days, any effect lingers
Community notes

What actually helps, according to the people doing it

Nobody's running trials on this. What follows is the folk wisdom that keeps surfacing in Reddit, peptide forums, and the Discord groups, sorted from "probably real" to "someone swears by it." Keep in mind, NONE of this is doctor advice.

Change how you inject (this helps most people)

The tip that comes up most on r/peptides is to add more water. Mix your vial with 3 or 4mL of bac water instead of 1 to 2mL. Same dose, spread thinner, so your skin reacts less.

Small habits people swear by

  • 1Let it warm to room temperature. Cold stings more.
  • 2Let the alcohol dry fully before the needle goes in.
  • 3Inject slow, over five to ten seconds.
  • 4Move your spot around, at least an inch from last time.
  • 5For a hard lump, warm compress after. For a red itchy welt, ice.

Treat the itch

This is where Benadryl and Zyrtec come up constantly on the boards. Most people take one 30 to 60 minutes before the shot if they know they tend to react. Claritin works too. Some skip the pill and use Benadryl cream before, or hydrocortisone cream after. Quercetin gets mentioned a lot as the gentler, natural option.

One heads up you'll also see repeated: taking an allergy pill before every shot can hide a real allergy building underneath. That's why some people don't do it by default.

The deeper end

In the more advanced threads, people keep KPV around and inject it when a reaction flares, and say it clears fast. Others try low-dose naltrexone (LDN) as a longer-term fix, but that's real experimenter territory. And a common reminder on the forums: if your reactions are suddenly bad or started with a new vial, the peptide itself might be the problem, not you.

When to stop and get help

Redness that spreads past a couple inches, streaks, feels hot, oozes, or comes with a fever means a possible infection. See a doctor. Hives all over, a swollen face or throat, or trouble breathing is a real allergic reaction. Act on that right away.

Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.

09

Is CJC-1295 with DAC approved?

And where the numbers on this page come from.

No. CJC-1295 with DAC is not approved for any use, anywhere. It is sold labeled for laboratory research only, and there is no legal route to buy it for human use.

What has happened recently

We have not yet written a full regulatory note for this compound. The status above is current as of the date shown.

What regulators say

From official documents

Banned in drug-tested sport. Most research peptides are prohibited under WADA's S0 category, which covers any substance with no approval from any regulatory authority for human use. That means a compound can be banned without ever being named on the prohibited list. Check with your own anti-doping authority rather than assuming absence from the list means permitted.
