CJC-1295 + Ipamorelin
Two different growth hormone signals at once
Why people pair them
Growth hormone release is controlled by two separate signals. GHRH (which CJC-1295 copies) tells the pituitary to make and release growth hormone; ghrelin-type signals (which ipamorelin copies) amplify each release. Because they work through different receptors, people combine them hoping for a bigger growth hormone pulse than either gives alone.
What the research shows
Studies in the 1990s showed that giving a GHRH and a ghrelin-type peptide together releases more growth hormone in people than either one alone. That synergy is real. But this specific pairing has not been tested in published trials for safety or long-term benefit, and neither peptide is an approved medicine.
Extra things to consider
- All the side effects of each: fluid retention, flushing, tingling hands, higher blood sugar
- Raised growth hormone and IGF-1 are a concern with any history of cancer
- People with diabetes or pre-diabetes may see blood sugar rise
- Often sold pre-mixed, so you can't change the amount of one without the other
Ask your doctor
- Is raising growth hormone appropriate for me at all?
- Do I need IGF-1 and blood sugar tests before and during?
- Would an approved option be safer for my goal?
