Overview

About CJC-1295

Mechanism of action

GHRH analogue; binds GHRH receptors on pituitary somatotrophs to stimulate pulsatile GH secretion. No DAC version has shorter action for more physiological GH pulses.

Safety profile

Water retention, numbness/tingling, insulin resistance (at high doses), fatigue, potential cortisol/prolactin increase. · Studied in human PK trials; well-tolerated; water retention, tingling reported; short-acting

Safety & Interactions

Contraindications & Drug Interactions

Research use only — not medical advice. Consult a licensed physician before using any peptide. Sources are cited where available.

⚠ CriticalContraindication

Active malignancy — sustained GH/IGF-1 elevation is a theoretical tumor growth risk.

! CautionCaution

Type 2 diabetes or pre-diabetes — reduced insulin sensitivity reported with chronic GH agonism.

ℹ NoteInteraction

Ipamorelin / GHRP-2 / GHRP-6 — standard synergistic combo, amplifies GH pulses.

Research

Studies & key findings

  • A GHRH analogue that extends the half-life of growth hormone-releasing hormone pulses, enabling once-daily or twice-weekly dosing versus native GHRH's minutes-long activity.
  • Paired with ipamorelin, CJC-1295 produces a robust, physiological GH pulse without blunting the normal GH feedback cycle.
