Evidence. No published human trials of this exact peptide.

Status

Approval
Not approved as a drug in the US or EU.
US compounding
Nomination withdrawn, so no longer in FDA Category 2 (April 2026). In December 2024 FDA’s advisory committee voted 0 to 13 against adding it to the 503A bulks list (1 to 12 for the acetate form). Not on the July 2026 agenda.
Sport (WADA 2026)
Banned in sportS2.2.4 growth hormone releasing factors: GHRH and its analogues, with CJC-1295 named. Mod GRF 1-29 is a GHRH analogue. Banned at all times.

Category 2 is FDA’s list of bulk substances that may present significant safety risks in compounding. The 503A bulks list adds substances that pharmacies may compound with. Advisory committee votes are advice; FDA makes the final decision. Sport status follows the WADA Prohibited List in force since January 1, 2026; athletes should confirm with their anti-doping organization. Checked October 5, 2026. Status of every compound.

How it works

CJC-1295 without DAC is the first 29 amino acids of growth-hormone-releasing hormone (GHRH), the brain signal that tells the pituitary to release growth hormone, with four swaps meant to slow its breakdown. Like GHRH, it is expected to act on GHRH receptors on the pituitary and trigger short pulses of growth hormone. No study has tested this exact peptide: FDA found no pharmacology studies of it in 2024 and said results for the DAC version can’t be carried over.

Not known

Whether it raises GH and IGF-1 in people, by how much and for how long, and what repeated daily use does have never been measured.

Protocol

Community

100 mcg per injection is most cited (range 50–300 mcg), 1–3× daily.

Frequency
1–3× daily (bedtime most common)
Route
Subcutaneous injection
Timing
Fasted (2+ hours after food), often 30 minutes before bed. Usually paired with ipamorelin.
Cycle
8–12 weeks on, about 4 weeks off.

Bedtime

Dose
100 mcg

Once nightly
How long
8–12 weeks, then about 4 off

Most cited. Taken fasted, 2–3 hours after the last meal, usually in the same shot as ipamorelin.

Split doses

Community
Dose
100 mcg
How often
2–3 times daily
How long
8–12 weeks

Fasted doses spread through the day, often including one at bedtime. Less common than bedtime only.

Draw 5 units5 mg + 2.5 mL

Taking it

Where it goes

Subcutaneous injection, rotating sites. Usually at bedtime on an empty stomach, 2–3 hours after the last meal.

If you miss a dose

No published guidance. Skip the missed dose and take the next one at the usual time; don’t double up.

What to expect

  1. Each dose

    A short GH pulse. Half-life is about 30 minutes, so it doesn’t build up the way the DAC version does.

    Community
  2. Weeks to months

    Better sleep, recovery and body composition are reported but untested; there are no human trials of this peptide.

Side effects and what to do

Flushing or warmth after the shot

Commonly reported and usually brief. Stop if it comes with hives, swelling or trouble breathing.

Injection-site redness or rash

Rotate sites. Stop if a rash spreads beyond the site.

Water retention, joint or muscle aches

Linked to higher GH and IGF-1. Lower the dose or stop if it persists.

Headache or tiredness

Usually mild. Stop if severe or persistent.

Higher blood sugar

GH raises glucose. Check fasting glucose, especially with prediabetes or diabetes.

Stop and get medical help

Hives with face, lip or throat swelling, trouble breathing, chest pain, or fainting: stop and get emergency care.

Who should avoid it

No product label covers CJC-1295 (no DAC), so these come from human studies and from precautions based on how it works. Most important first.

Anyone with active or past cancer
PrecautionIt is designed to raise growth hormone and IGF-1, which promote cell growth, and FDA notes that mice making excess GHRH develop pituitary tumors. No study has tested this peptide.
Diabetes or high blood sugar
PrecautionGrowth hormone raises blood sugar, and FDA says the diabetes risk on growth hormone labels may also apply to drugs like this that raise GH. Its effect on blood sugar has never been measured.
Pregnancy or breastfeeding
PrecautionNo human safety data exist.
Anyone relying on product quality
PrecautionIt isn’t an approved drug, so vials have no regulated standard for identity, purity or sterility. FDA notes the names for the versions with and without DAC are used inconsistently.

Interactions

No interaction studies have been published, and no product label lists any.

Precaution: follows from how it works or from a related drug, and hasn’t been tested. This isn’t a complete list: a pharmacist or doctor can check a specific medicine or condition.

Tracking and pairing

Worth tracking

  • IGF-1
  • Fasting glucose
  • Thyroid (TSH, free T4)
  • Swelling or hand numbness

Often paired with

  • Ipamorelin

    The standard pairing: a GHRH analog plus a ghrelin-receptor agonist, often premixed. Never tested together in a published trial.

Human studies

No published human studies of CJC-1295 (no DAC) turned up in our October 2026 review. The evidence note at the top of this page sums up what is known.

Limits of the evidence

No published study has given this exact peptide to people or animals; FDA found none when it reviewed it in 2024. The human results often quoted for it come from CJC-1295 with DAC, a different, longer-acting molecule. The doses people inject, repeated daily use, long-term safety and product purity are all untested.

What is the usual CJC-1295 (no DAC) dose?

From community reports, not established: 100 mcg per injection is most cited (range 50–300 mcg), 1–3× daily. These are the amounts sources reference, not recommendations.

How much water do I mix CJC-1295 (no DAC) with?

There’s no single right amount, because the water only sets the strength. With 2.5 mL of bacteriostatic water in a 5 mg vial, the strength is 2 mg/mL, so 100 mcg is 5 units on a U-100 insulin syringe. More water makes small doses easier to measure. The dose chart above shows other volumes.

Who should avoid CJC-1295 (no DAC)?

No product label covers CJC-1295 (no DAC), so these come from human studies and from precautions based on how it works.
