REGULATORY STATUS / 06

CJC-1295: frequently asked questions, answered from the record.

Safety, side effects, FDA status, the DAC modification, and the testosterone questions — each answered directly and cited to a study. Research framing only; not for human use.

Safety and regulatory status

The questions here are answered from the published record. CJC-1295 is not approved for human use anywhere, and these answers describe what studies measured — not what anyone should do. Two framing facts apply across the whole section: the human evidence base is limited to early pharmacokinetic studies in healthy volunteers [1], and the compound is prohibited at all times in sport under WADA Section S2 and banned by bodies such as the NCAA [6]. Where an answer cites a general GH-axis effect rather than a CJC-1295 study, it says so.

Side effects and the testosterone questions

The side-effect picture comes mainly from GH-axis physiology, since CJC-1295-specific human data are sparse [1][12]. The testosterone questions recur often — they appear in several forms in search data — and the answer is consistent across all of them: CJC-1295 works on the GH/IGF-1 axis, not the hypothalamic-pituitary-gonadal axis, so there is no documented direct effect on testosterone in either direction [1][2].
