AT A GLANCE.

§ 01 · TL;DR

THE QUICK READ.

A GHRH analog that amplifies growth hormone release. Often stacked with Ipamorelin for synergistic effects.

Extends the duration of natural GH release by mimicking growth hormone releasing hormone (GHRH).

WHAT IT MIGHT HELP WITH.

1
Amplified GH release when stacked
2
Improved body composition
3
Enhanced recovery
4
Better sleep quality
5
Synergy with secretagogues

HOW IT WORKS.

§ 02 · MECHANISM

Extends the duration of natural GH release by mimicking growth hormone releasing hormone (GHRH).

Modified GHRH analog with increased half-life. DAC version provides sustained release; no-DAC version allows pulsatile dosing.

WHO IT'S FOR
  • GH optimization seekers
  • Stack with Ipamorelin
  • Athletes
  • Anti-aging protocols
WHO SHOULD AVOID
  • Cancer history
  • Active malignancy
  • Pregnant/nursing

COMMON QUESTIONS.

§ 08 · FAQ
What's the difference between CJC-1295 with and without DAC?
DAC (Drug Affinity Complex) extends half-life from 30 minutes to ~8 days. No DAC allows natural pulsatile GH release; DAC provides more constant elevation. Most research prefers no DAC for physiologic patterns.
Why combine CJC-1295 with ipamorelin?
They work through different mechanisms - CJC-1295 (GHRH pathway) amplifies release, ipamorelin (ghrelin pathway) triggers the pulse. Together they produce significantly greater GH release than either alone.
Is Mod GRF 1-29 the same as CJC-1295 no DAC?
Yes, they're the same compound. Mod GRF 1-29 is the technical name for the modified GHRH fragment. 'CJC-1295 no DAC' or 'CJC-1295 without DAC' are common trade names.
What's the flushing side effect?
Some experience facial flushing/warmth shortly after injection. This is common with GHRH analogs and typically diminishes over time. It indicates the peptide is active.
