CJC-1295 with DAC: research, legal status and who sells it

What it is

CJC-1295 is a synthetic, long-acting analogue of growth hormone-releasing hormone (GHRH) [9].

Research status

The main human data come from two small randomized, placebo-controlled trials in healthy adults, published in 2006. A single injection raised average growth hormone levels 2- to 10-fold for six days or more and IGF-I levels 1.5- to 3-fold for 9 to 11 days, and the estimated half-life was 5.8 to 8.1 days [9]. After repeated doses, IGF-I levels stayed above baseline for up to 28 days, and the authors reported no serious adverse reactions in those trials [9]. CJC-1295 did not go on to approval [1]. Evidence for CJC-1295 combined with ipamorelin comes from animal studies only [10].

Regulatory status

CJC-1295 is not FDA-approved [1]. Its nomination for pharmacy compounding was withdrawn after FDA identified serious adverse events associated with it, including increased heart rate and a systemic vasodilatory reaction, and noted that clinical data are limited [2]. No CJC-1295 medicine is authorized in the UK, the EU or Canada [3][4][6]. Australia lists it in Schedule 4 with possession controls [7], and WADA names it as a prohibited GHRH analogue [8].

Quality and testing considerations

FDA cites potential immunogenicity and complexities with peptide-related impurities and characterization [2]. Anti-doping laboratories have repeatedly found modified growth-hormone-releasing peptides in black-market products, such as versions with an extra glycine added [11][12]. WADA’s list names CJC-1293 and CJC-1295 as separate examples of prohibited GHRH analogues [8]. Because products with similar names can be different molecules, a certificate of analysis should confirm the exact molecule by mass, not just report purity. A 2026 review listed CJC-1295 among peptides marketed directly to patients and noted that rigorous human safety data for unapproved peptides are scarce [13].

Where it’s sold

CJC-1295 is sold online as a “research use only” peptide, alone and blended with ipamorelin; the tables below track listings. Many vendors also sell a version without the drug affinity complex, labeled “CJC-1295 no DAC” or “Mod GRF 1-29”. It is a different molecule [14], so we price the two separately: CJC-1295 with DAC and CJC-1295 without DAC.
