Synthetic growth-hormone-releasing hormone (GHRH) analogue. Stimulates pituitary GH release. The DAC variant binds albumin for extended half-life; 'no-DAC' (mod GRF 1-29) is short-acting.
Half-life
no-DAC: ~30 min; DAC: ~6-8 days
Administration
subcutaneous
Typical dosage*
low: 100mcg (no-DAC) · typical: 100-200mcg per dose (no-DAC, 1-3x/day) · high: DAC 2mg/week

Questions (9)

What is CJC-1295?

CJC-1295 (CJC-1295 (with or without DAC — Drug Affinity Complex)). Synthetic growth-hormone-releasing hormone (GHRH) analogue. Stimulates pituitary GH release. The DAC variant binds albumin for extended half-life; 'no-DAC' (mod GRF 1-29) is short-acting.

What is CJC-1295 used for?

Commonly discussed uses: GH axis support (research), body composition, recovery/sleep (anecdotal). There is both human and animal/preclinical research, though the depth and quality vary by indication. Note: most uses are not approved indications.

How does CJC-1295 work?

Mechanism: Synthetic growth-hormone-releasing hormone (GHRH) analogue. Stimulates pituitary GH release. The DAC variant binds albumin for extended half-life; 'no-DAC' (mod GRF 1-29) is short-acting.

Is CJC-1295 safe?

Reported considerations: anecdotal: injection-site reaction, flushing, head-rush, water retention. There is both human and animal/preclinical research, though the depth and quality vary by indication. WADA-prohibited. Not approved for human therapeutic use. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of CJC-1295?

Commonly cited ranges (educational reference, not a recommendation): low 100mcg (no-DAC), typical 100-200mcg per dose (no-DAC, 1-3x/day), high DAC 2mg/week. Administration: subcutaneous. Half-life: no-DAC: ~30 min; DAC: ~6-8 days.

Is CJC-1295 legal in Australia?

Australian status: Not ARTG-registered; prescription-only/research. WADA-prohibited. Not approved for human therapeutic use. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store CJC-1295?

Reconstitution/storage reference: 2ml BAC water per 2-5mg vial; storage: reconstituted refrigerated, ~few weeks.

What is CJC-1295 commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): CJC-1295 + Ipamorelin (GH-axis stack). Stacking increases interaction/safety uncertainty.
