CJC-1295 (DAC) 10mg — Research Protocol Reference

SKU CD10 · Last reviewed 29 July 2026

CJC-1295 DAC is administered subcutaneously once weekly. The DAC modification extends its half-life to 6–8 days. Daily dosing is not required and is not recommended. Inject into the abdomen or upper thigh. Evening injection is preferred to align the GH pulse with the body's natural overnight GH secretion window.

Contraindicated in active cancer or a history of hormone-sensitive cancers. Do not use alongside exogenous GH without medical supervision. Not for use during pregnancy.

12-week cycle based on clinical trial data showing sustained IGF-1 elevation with consistent weekly dosing. The DAC modification keeps CJC-1295 active for 6–8 days per injection. One vial covers a full 5-week intro phase at 1,000mcg weekly.

• Day of week: Choose one fixed weekly injection day.
• Time of day: Evening preferred. Aligns GH pulse with overnight sleep window.
• Food: Avoid high-carbohydrate meals immediately before injection. A 2-hour post-meal gap is sufficient.
• Site rotation: Alternate between abdomen and upper thigh each weekly injection.
• Rest period: 2–4 weeks minimum after the 12-week cycle before resuming.

• Half-life advantage: The DAC modification binds CJC-1295 to albumin, extending activity to 6–8 days per injection.
• IGF-1 monitoring: Consider baseline and mid-cycle IGF-1 panels. CJC-1295 DAC can elevate IGF-1 by 1.5–3×.
• Stack note: Commonly paired with a GHRP for dual-pathway GH stimulus. Do not mix in the same syringe.
• Water retention: Mild retention in weeks 1–4 is common as GH levels rise. Typically resolves as the body adapts.

Taking too much CJC-1295 DAC can increase side effects. Signs the dose may be too high:

• Significant water retention: Persistent bloating or swelling indicates IGF-1 above therapeutic range.
• Joint pain or stiffness: Carpal tunnel-like symptoms and joint discomfort are well-documented signs of GH excess.
• Fatigue or lethargy: Paradoxical fatigue suggests the GH axis is being overstimulated.
• Tingling or numbness: Nerve compression from water retention. Reduce dose immediately.

A dose may be too low if expected effects are absent after consistent use:

• No improvement in recovery by week 6: Faster post-training recovery is one of the earliest measurable effects.
• No body composition changes by week 8: Lean mass preservation and fat reduction should be measurable by mid-cycle.
• No sleep quality improvement: No change in sleep quality by week 4 is a common sign of underdosing.
