What is CJC-1295 no DAC (Mod GRF 1-29)?
Plain language first. The technical label stays, but it never stands alone.Overview
What it's used for
The short-acting version that gives a quick growth-hormone pulse closer to your body's natural rhythm. It is usually paired with ipamorelin for muscle, fat loss, and recovery.
How does CJC-1295 no DAC (Mod GRF 1-29) work?
What it does in the body, and where.This is the same GHRH copy as CJC-1295 with DAC, minus the anchor that makes it last. That one difference changes everything about how it behaves.
- 01It prompts the pituitary through the GHRH receptorIdentical mechanism to the DAC version.
- 02It clears in about half an hourProducing a pulse rather than a raised baseline, which is closer to how your body releases growth hormone naturally.
- 03The famous figures do not apply hereThe two-to-tenfold growth hormone numbers quoted for CJC-1295 come from the DAC version only. This is the most common mix-up on this compound.
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- No dataThere is no published human trial of this version specifically.
- Human trialIts half-life is about 30 minutes, against roughly a week for the DAC version, so it behaves completely differently.
The famous 2 to 10-fold growth hormone figures are from the DAC version and do not apply here. This version has no published human trial of its own and clears in about 30 minutes rather than a week.

Four things to know about CJC-1295 no DAC (Mod GRF 1-29)
How much, and do you cycle it?
The range, and whether you take breaks.0.1 mg per dose, daily to 2x daily. Commonly cycled, usually 8 to 12 weeks on and 4 off Community practice
Because it clears in about half an hour it produces a pulse rather than a raised baseline, which is the argument users give for needing less of a break than the DAC version. Neither schedule has been tested.

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 no DAC (Mod GRF 1-29) 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.
What are the side effects and cautions?
Known cautions and warnings for this compound.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: 31% charged residues, 45% 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
- Active cancer, as a precaution with anything raising growth hormone
- Pregnancy
- Banned in drug-tested sport
Stop and get help
- Spreading hives, face or throat swelling, or trouble breathing

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.
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.

Checked 11 September 2026FDA: Certain Bulk Drug Substances for Use in Compounding that May Present Significant Safety Risks (category 2 and withdrawn nominations), current as of April 22, 2026Prohibited at all times, in and out of competition. S2.2.4 Growth hormone releasing factors: GHRH and its analogues (e.g. CJC-1293, CJC-1295, sermorelin and tesamorelin). Non-Specified.
Checked 12 September 2026WADA: The 2026 Prohibited List (in force 1 January 2026)
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.
