CJC-1295 papers describe tests and leave health questions open

The numbers beside findings lead to the papers listed here

CJC-1295 has been studied briefly in people, despite many claims of health gains. This list of papers lets you check what the researchers actually found.

The little numbers beside findings match the numbered papers and public documents below. Each entry includes a link or study number to help you find the original.

In early-2006, Teichman's healthy adults had a 2- to 10-fold growth hormone rise: two to ten times the earlier level ^[1]. That blood rise wasn't proof of better health.

The liver's growth-related hormone rose too, and blood changes lasted for days. Half the compound left blood within an estimated 5.8-to-8.1-day period.

Another study that year found higher growth hormone without stopping its normal bursts ^[8]. In two thousand nine, researchers found changes in blood proteins in healthy young men ^[10].

A study in mice born unable to make a natural growth-starting hormone checked growth ^[9]. Those animal results don't establish what taking the compound would do for you.

Separate studies tested rat hormones and sports lab methods

In 1986, researchers measured how quickly the original natural hormone left healthy men's blood ^[6]. Later work tried to make related compounds last longer in blood.

During two thousand five, Jette tested CJC-1295 joined to blood protein in rats ^[7]. Across two hours, the total hormone measured was 4-fold higher: four times the unattached version's result.

A separate test in lab liquid showed resistance to a protein that normally breaks hormones down. That was a test of breakdown, rather than a treatment test in people.

Two thousand two: related hormone research gave a reason to study two compounds together ^[15]. That work didn't establish health gains from a specific pair in healthy adults.

In 2010, Henninge identified the compound in an unknown seized product ^[2]. Later tests found very small amounts of related compounds in human blood ^[3][4].

Researchers also checked that a test could identify the compound in horse blood ^[13]. A 2021 review brought together advances in tests for these hormone-raising compounds ^[5].

The 2025 review covered related hormone-raising compounds and their medical research ^[12]. Sports rules ^[14] and 2024 FDA advisers' papers ^[11] cover bans and pharmacy concerns.

Lab catalogues disagree about the compound's makeup and the weight of one molecule, its smallest unit. That lab weight isn't a shot amount, and the disagreement can't prove safe treatment.
