CJC-1295 and Sleep Optimization: What Has Been Studied
What the research covers
No published study was found that measured sleep in people or animals given CJC-1295. The human studies measured growth hormone and IGF-I in healthy adults. CJC-1295 is a lab-made form of GHRH, a hormone that drives the release of growth hormone (GH). After a shot, it binds to albumin, a blood protein, so it lasts much longer than natural GHRH.
One study took blood every 20 minutes over 12 hours overnight. Healthy men aged 20 to 40 were tested before and one week after one shot of 60 or 90 micrograms per kilogram. GH still came in pulses, at the same rate and size as before. The level between pulses rose 7.5 times. The study measured hormones in blood, not sleep.
Two trials tested it against placebo in healthy adults aged 21 to 61. The shots went under the skin. The trials ran for 28 and 49 days. The estimated half-life was 5.8 to 8.1 days. No serious adverse reactions were reported.
A PubMed search on 27 September 2026 found no study of CJC-1295 and sleep. The two hits were a review and a study of online posts.
