CJC-1295 No DAC (Mod GRF 1-29)

What is CJC-1295 No DAC (Mod GRF 1-29)?

CJC-1295 No DAC, better known as Mod GRF 1-29, is a lab-made peptide that nudges your own pituitary to release a short pulse of growth hormone, and the "No DAC" part is the whole point. It activates the growth-hormone-releasing-hormone receptor, then clears in about 30 minutes, so it mimics the brief, natural rise and fall your body produces on its own. That is the version people stack with ipamorelin. Its long-acting sibling, CJC-1295 with DAC, binds to albumin and keeps growth hormone elevated for 6 to 8 days, a sustained "bleed" most experienced users avoid as non-physiological.

Safety watch-outs

• Worsening or progressive reaction with each injection (possible sensitization): stop immediately.
• New or worsening numbness or tingling (possible fluid-related nerve compression): reduce dose or stop.
• Rising fasting glucose or HbA1c: stop and consult a clinician, especially with diabetes.
• Any active or suspected cancer: do not use
• growth-hormone-axis stimulation is contraindicated.
