CJC-1295 with DAC 5mg Research Peptide Vial

CJC-1295 with DAC 5mg: A Long Acting GHRH Analog

CJC-1295 with DAC started out as a Canadian biotech project, developed by a company called ConjuChem back in the mid 2000s. It's built from a 29 amino acid backbone, based on the natural hormone that triggers growth hormone release, but with a few key swaps along the chain meant to make it hold up better in lab conditions.

Structure and Identity

Formula: C152H252N44O42 for the base peptide, before the DAC portion is added
Weight: around 3,647 g/mol without DAC
Backbone: Modified GRF(1-29) with substitutions at four positions
DAC component: A lysine linked derivative attached at the C-terminus, allowing the molecule to bind serum albumin

That albumin binding is really the whole point of DAC. Natural GHRH clears out of the body in just minutes. Once DAC gets attached, the half life stretches out to something closer to a week, which is a massive jump for a peptide this size.

What Labs Study It For

A few research threads tend to dominate the CJC-1295 with DAC literature:

GHRH receptor binding and activation
Sustained growth hormone release patterns
Downstream IGF-1 production in liver tissue
Pituitary somatotroph signaling
Comparative studies against shorter, non DAC GHRH analogs

Researchers working with Selank sometimes bring CJC-1295 with DAC into parallel studies too, particularly when comparing how different long acting and short acting peptides behave across hormonal and neurological research models.

Regulatory Status

CJC-1295 with DAC has no FDA approval for any therapeutic use. It's sold strictly as a research compound, and it's also listed on WADA's prohibited substances list for sport related contexts.

Legal and Safety Info

Not a supplement, just a raw research material. Keep it away from kids. Long term safety data is limited, so only trained lab personnel should be handling this.

Buying this means agreeing to use it legally, for research purposes only.
