CJC-1295 Dosage Guide: Protocols, Timing & How Much to Take (2026)

From Peptidepedia, the trusted peptide wiki.

Dosage Protocols

No FDA-approved dosing guidelines exist for CJC-1295. The following protocols are derived from clinical research and community reports.

CJC-1295 without DAC (Mod GRF 1-29)

  • Conservative starting dose: 50–100 mcg per injection
  • Standard dose: 100–200 mcg per injection
  • Frequency: 1–2 times daily (bedtime dose is considered most important)
  • Timing: Often administered before bed to coincide with natural GH release, and/or upon waking
  • Cycle length: 8–12 weeks, followed by 4 weeks off

CJC-1295 with DAC

  • Starting dose: 300 mcg per injection twice weekly
  • Maintenance dose: 300–600 mcg once or twice weekly
  • Cycle length: 8–12 weeks

Cycling Guidelines

Most practitioners recommend cycling CJC-1295 to prevent receptor desensitization and maintain the body's responsiveness to the peptide. A common approach involves 8–12 weeks on, followed by 4–8 weeks off. Some users employ a 5 days on, 2 days off weekly schedule with the non-DAC version to preserve pulsatile release patterns.

Frequently Asked Questions

For CJC-1295 with DAC, simply resume your regular schedule. Do not double dose. For CJC-1295 without DAC, missing occasional doses is less significant due to the frequent dosing schedule; simply continue with your next planned injection.
