CJC-1295 Medicine

An unrolled scroll of what the medical literature actually says about CJC-1295 — the GHRH analog, the DAC variant, the discontinued clinical program.

What researchers gave and saw

Which CJC-1295 dosage amounts were used in studies?

Healthy adults got one skin shot of 30, 60, 125, or 250 micrograms per kilogram. Stage 2 used 60-240 micrograms per kilogram weekly. Neither study set a dose for you.

How much did people receive in each study?

In a 2006 paper, researchers described two human studies. A later stage 2 test enrolled adults with HIV and extra fat around their organs [01][18]. That later test began asking whether treatment helped while it kept watching harm. These papers record study amounts; they don't set an amount for your care.

In 2006, healthy adults ages 21 to 61 got one CJC-1295 skin shot, with long-form amounts of 30, 60, 125, and 250 micrograms per kilogram [01]. A microgram is a tiny measure of weight. The listed amount rose with each person's weight, so you still can't picture one total without that weight. Another group got 30-60 micrograms per kilogram weekly or every other week. Those tests ran for 28- to 49-day periods [01]. At 30-60 micrograms per kilogram, most people got through the short study without serious harm. Sore skin, a brief flush, and headache were most common [01].

ConjuChem, the company that made CJC-1295, ran the stage 2 study. One group got 60, 90, and 120 micrograms per kilogram each week. Another got 60, 120, and 240 micrograms per kilogram. About 192 people were due to take part for twelve weeks [18]. The study didn't finish.

I'd ask what those amounts proved before trusting them. None was chosen for your body, your illnesses, or your other medicines.

Why were the two forms given on different schedules?

The long form lasted about a hundred times longer, so researchers didn't use one schedule.

In stage 1, the first human tests, and stage 2, the later test, people got the long form in a weekly skin shot [01][12]. Its extra part joins albumin, which carries substances in blood. The stage 1 paper says one weekly shot containing 30-60 micrograms per kilogram kept insulin-like growth factor above its starting level through a 28-day study. This liver-made hormone helps tissue grow.

Studies used the short form in 1-3 shots each day because half left blood around the thirty-minute point [13]. Each shot led to a growth hormone burst of about 60-90 minutes [13]. The forms can't be swapped shot for shot: one leaves fast and the other stays for days.

A research schedule doesn't fit your health; your doctor needs your full history.

What does CJC-1295 half-life say about each form?

CJC-1295 half-life tells you when half the drug is gone from your blood. In a 2006 study, researchers estimated 5.8 to 8.1 days for the long form in healthy adults [01]. Half the short form left in about 30 minutes. With sermorelin, an older related drug that gives your gland a similar message, half was gone in less than ten minutes [04][13].

The long form binds albumin, a protein that moves substances through your body. About half the albumin takes close to 19 days to leave the body [12]. In a rat test by ConjuChem, the drug company, CJC-1295 appeared in blood within 15 minutes after binding albumin. It was still there beyond 72 hours [03][14]. The short form can't bind, so it left much sooner.

A time claim must name the form. Even then, it isn't a promise about your body.

How long did blood or urine tests find each form?

A test may find the drug after its main effect fades. Tests found the long form in blood for about 14-21 days because albumin held it there. Albumin is a common blood protein. Its message at your growth gland lasted six to eight days per dose [01][12]. The short form didn't last for days.

A urine test can find a tiny trace [19]. A blood test can show the long form bound to albumin [09]. Sports officials use these tests to enforce their rules. A trace can't tell you how you feel, whether your health changed, or what treatment would do.

How was the drug given in human and rat studies?

In 2006, both the one-shot and repeat groups received shots under the skin [01]. The later stage 2 test used skin shots too [18]. Rat studies used shots into a vein or under the skin [03]. Other rat tests used a shot into the belly [03].

Those are study facts, not directions for you. No human paper reports CJC-1295 taken by mouth, into a muscle, or through the nose. A lab method can't account for your other health problems.

What did one paper say about keeping the drug cold?

One paper says the dry drug didn't break down when kept at 20 degrees below zero celsius [13]. After researchers added germ-free water and a preservative, the liquid kept for several weeks in a refrigerator. Air can damage the long form's albumin-binding part. A damaged drug may not attach to albumin in your body [13].

This isn't a guide for you. Your kitchen can't match a clean lab, and the paper doesn't tell you if a home vial stayed clean.

Why can't a study amount become your dose?

Researchers chose amounts for certain groups and watched them closely. Those figures aren't dose advice. The FDA hasn't approved CJC-1295 for medical use. In December 2024, U.S. advisers weighed whether pharmacies could use the powder to make custom medicine for one patient. They didn't support that use [20].

Some vials marked for research haven't passed the FDA checks required of approved medicine for strength, purity, and freedom from germs. A label can't prove a vial meets those standards. The studies included few kinds of people, and there isn't an accepted medical dose a doctor could simply apply to you.

Nothing here can pick an amount for your body or protect you from an unsafe vial.
