CJC - No DAC10 mg

Mod GRF 1-29. Short-acting growth hormone releasing analog. Lyophilized powder for reconstitution.

What it is

CJC-1295 without DAC, also called Mod GRF 1-29, is a synthetic 29-amino-acid analog of growth hormone releasing hormone. It carries four substitutions on the human GRF(1-29) backbone that slow enzymatic breakdown, but it lacks the albumin-binding DAC linker, so its action stays short. It appears in endocrinology research on the pituitary growth hormone axis.

How it works

CJC-1295 without DAC, also called Mod GRF 1-29, is a short-acting GHRH analog studied for pulsatile growth hormone release.

GHRH

The active core

Mod GRF 1-29 keeps the active first 29 amino acids of GHRH, with four substitutions that resist enzymatic breakdown.

Pulse

Keeps the natural rhythm

Without the DAC extension the peptide clears within about 30 minutes, preserving the pituitary's pulsatile pattern in models.

Pairing

Often studied in pairs

Research frequently combines the short-acting form with a ghrelin receptor secretagogue such as ipamorelin.

Key benefits

  • Growth-and-performance research focused on the GH axis and lean mass.
  • Recovery and body-composition protocols using short, timed GH pulses.
  • Commonly paired with a GHRP for a fuller growth-and-performance plan.

Laboratory research only. Not for human or veterinary use.

What published research is studying

Mixed evidence base
  • Stimulation of pituitary growth hormone release through the GHRH receptor (in vitro and rodent work)
  • Restoration of the growth hormone and IGF-I axis in older adults (small controlled trials of GHRH(1-29) analogs)
  • Resistance of modified GRF(1-29) sequences to enzymatic degradation
  • Body composition measures such as lean mass and skin thickness in ageing research

No published human trial has tested this exact tetrasubstituted GRF(1-29) sequence. The human data come from small studies of closely related GHRH(1-29) analogs, and the molecule-specific work is preclinical.

Key research findings and references

Key research findings

In Sprague Dawley rats, a tetrasubstituted hGRF(1-29) derivative produced a 4-fold larger 2-hour growth hormone area under the curve than unmodified hGRF(1-29). It also resisted dipeptidyl peptidase-4 in vitro.

Jetté L et al., Endocrinology 2005

In 10 healthy men aged about 68 years, GHRH(1-29) given twice daily for 14 days raised 24-hour growth hormone and IGF-I. Levels no longer differed significantly from those of healthy young men.

Corpas E et al., J Clin Endocrinol Metab 1992

Published study duration

  • GHRH(1-29) analog study in adults aged 55 to 71: 16 weeks of nightly injections after a 4-week placebo run-in (Khorram 1997).
  • GHRH(1-29) study in healthy older men: two 14-day treatment periods separated by 14 days without treatment (Corpas 1992).
  • Rat work on modified hGRF(1-29) analogs: single subcutaneous doses with plasma sampling from 15 minutes to 72 hours (Jetté 2005).

Research endpoints

  • Peak and 24-hour integrated growth hormone concentrations
  • Growth hormone area under the curve after a single dose
  • Serum IGF-I and IGFBP-3
  • Lean body mass and fat mass by DXA
  • Skin thickness

Research handling

Full handling guide
  1. 01

    Lyophilized, sealed, batch-numbered

    Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.

  2. 02

    Store cold and dark

    Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.

  3. 03

    Reconstitute with bacteriostatic water

    The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.

  4. 04

    Research use only

    Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.

Before you order

What ships in the box?

The vials selected, plus a free supply kit with every vial: one 3 ml bacteriostatic water, ten 0.5 ml syringes and ten alcohol swabs per vial, and the uu.life research handling card.

How does volume pricing work?

The price per vial depends on how many vials of the same strength are on the line. 3-4 vials take 5% off, 5 or more take 10% off. The discount is applied automatically and shows on the product page, in the cart and at checkout.

Is every batch tested?

Yes. Every batch is tested by an independent laboratory for identity and purity, and the Certificate of Analysis is linked from this page and the lab-testing library.
