CJC-1295 with DAC

Also known as: CJC-1295 DAC, Drug Affinity Complex CJC, Modified GRF 1-29 DAC

A long-acting GHRH analog with extended half-life for sustained GH elevation.

Overview

CJC-1295 with DAC (Drug Affinity Complex) is a modified growth hormone releasing hormone analog with a maleimidopropionic acid group that binds to albumin, dramatically extending its half-life to 6-8 days. This allows for less frequent dosing but creates sustained GH elevation rather than pulsatile release.

Mechanism of Action

Activates GHRH receptors on pituitary somatotrophs to stimulate GH release. The DAC modification binds to serum albumin, protecting from degradation and extending half-life from minutes to days. Creates sustained rather than pulsatile GH elevation.

Pharmacokinetics

Half-life 6-8 days due to albumin binding. Once or twice weekly dosing. Sustained GH and IGF-1 elevation.

Dosing Protocols

Key Research Findings

  • 1Dramatically extended half-life vs non-DAC version
  • 2Sustained IGF-1 elevation for days
  • 3Less frequent dosing required
  • 4May cause GH bleed rather than natural pulses

Side Effects & Contraindications

Reported Side Effects

  • Water retention
  • Tingling
  • Fatigue
  • Joint pain

Contraindications

  • Active malignancy
  • Diabetic retinopathy

Safety Considerations

Research compound. Sustained GH elevation differs from natural pulsatile release. May increase side effects vs non-DAC version. Monitor IGF-1 levels.

Storage Requirements

Refrigerate 2-8°C after reconstitution
