Growth Hormone
CJC-1295 DAC
Studied for how it affects the body's natural growth-hormone rhythm in recovery research. Research-grade CJC-1295 with DAC is a synthetic 30-amino-acid growth-hormone-releasing hormone (GHRH) analog. Its drug affinity complex stretches the documented half-life to 6-8 days.

How CJC-1295 with DAC works, in plain words
- CJC-1295 is a lab-made copy of the first 29 amino acids of GHRH.
- It docks on the GHRH receptor on the pituitary, a pea-sized gland under the brain, telling it to release growth hormone.
- DAC, short for drug affinity complex, is a small chemical handle. It holds on to albumin, the most common protein in blood.
- Riding on albumin is why this version lasts days instead of being cleared in minutes.
- More growth hormone tells the liver to make more IGF-1, the messenger most growth-hormone research actually measures.
These are findings investigators reported in their own study participants. They are not a result for this vial, and not a result for any reader. CJC-1295 is not approved by Health Canada or the FDA for any human or veterinary use, and everything Lux BioPure sells is supplied for laboratory research use only.
How it works, step by step
Step 1 of 3GHRH receptor, on the pituitary gland
Step 1 · Target
GHRH receptor, on the pituitary gland
- CJC-1295 sits in the same docking point natural GHRH uses and switches it on.
- Four swapped amino acids slow the enzymes in blood that chew the copy up.
- Studied for growth hormone made in the gland and let out.
The gland makes growth hormone and lets it out
- That is the message the docking point carries.
- The copy lasts longer in blood than the natural hormone does.
Step 2 of 3Albumin, the carrier protein in blood
Step 2 · Target
Albumin, the carrier protein in blood
- Albumin is the most common protein floating in blood.
- The DAC handle latches onto it and rides along with it.
- Studied for how long the peptide is carried before it is cleared.
Carried for days instead of cleared in minutes
- Albumin itself lasts about nineteen days.
- The peptide rides with it rather than being cleared in minutes.

Step 3 of 3IGF-1, made in the liver
Step 3 · Target
IGF-1, made in the liver
- More growth hormone in the blood tells the liver to make more IGF-1.
- The liver is where that messenger is made.
- The messenger most growth-hormone research actually measures, because it holds steadier in a blood sample.
The messenger research actually measures
- IGF-1 holds steadier in a blood sample than growth hormone itself does.
- That is why studies read IGF-1 rather than growth hormone.
What is CJC-1295 DAC?
Research has looked at its role in holding growth hormone pulses higher for longer, and in raising IGF-1. It has also looked at where it might fit in recovery and body-composition research models.
The 10 mg vial suits longer research protocols. Mix with bacteriostatic water and store the mixed solution at 2-8°C.

Research Profile
preclinical research consensus for informational comparison only
What arrives, and what to do with it
The vial ships lyophilized, a sealed powder, not a ready-to-use liquid. It needs bacteriostatic water and a clean workspace before it is usable in a protocol.
What's in the box
One sealed 10 mg vial of lyophilized powder, with its lot number printed on the label. Bacteriostatic water is sold separately, so it goes in the order too if there is none on the bench.
Store cool and dark, then cold once mixed
The label on the vial says it plainly: store in a cool, dark place. Sealed, the powder holds up to 24 months at room temperature or in the fridge. Once reconstituted, refrigerate at 2-6°C and use within 60 days.
How to tell it went right
DAC peptides foam easily, so the water goes in slowly and the vial sits for five minutes before it is gently rolled. The solution can look slightly cloudy at first and should clear. If it stays cloudy, or shows particles, or the lot on the vial does not match the report on our lab reports page, stop and contact us before it goes into a protocol.
Questions about CJC-1295 DAC
What is CJC-1295 with DAC studied for?
It is a lab-made copy of the first 29 amino acids of GHRH, the signal that tells the pituitary gland to release growth hormone. Research follows what happens next: more growth hormone tells the liver to make more IGF-1, the messenger most growth-hormone research actually measures.
What does the DAC part change?
It makes the molecule last days instead of minutes. DAC, short for drug affinity complex, is a small chemical handle that holds on to albumin, the most common protein in blood. A published human study reported a half-life of about 120 hours for the version carrying DAC, against about 30 minutes for the version without it.

Is CJC-1295 DAC legal to buy in Canada for research?
Research peptides sold only for in vitro laboratory use sit in a legally distinct category from approved drugs, and that is the category this vial is sold in. Health Canada classifies a substance by marketing intent under the Food and Drugs Act, not by molecular structure, and Canada runs no licensing registry for research chemicals. CJC-1295 holds no Drug Identification Number.
How is each batch tested?
An independent lab, Janoshik, runs HPLC and mass spec on every batch before it goes on sale. The report is published under the lot number printed on the vial label, so the two can be matched on arrival. The HPLC purity recorded for this product is 98%+.
What arrives in the box, and how is it stored?
One sealed 10 mg vial of lyophilized powder, with its lot number printed on the label. Sealed, the powder holds up to 24 months at room temperature or in the fridge. Once reconstituted it is refrigerated at 2-6°C and used within 60 days.
Is CJC-1295 DAC for human use?
No. Everything Lux BioPure sells is supplied for laboratory research use only, not for human or veterinary use, and not to diagnose, treat, cure or prevent any disease. CJC-1295 is not approved by Health Canada or the FDA for any human or veterinary use.
