Why are CJC-1295 and ipamorelin studied together?

They act on the growth-hormone axis through two different but complementary mechanisms - CJC-1295 as a GHRH analog and ipamorelin as a secretagogue - so research often pairs them, and they are commonly sold as a combined blend.

What is the difference between CJC-1295 with DAC and no DAC?

DAC stands for Drug Affinity Complex, a modification that extends the compound's half-life. CJC-1295 without DAC (sometimes called mod GRF 1-29) has a shorter action, while the DAC version circulates longer. Both are research materials.

How are they reconstituted and stored?

They ship as lyophilized powder and are reconstituted with bacteriostatic water, with the water volume setting the mg/mL concentration. Reconstituted vials are refrigerated and, as a general research guideline, used within about 28 days.

CJC-1295 & ipamorelin: research overview

Q: What are CJC-1295 and ipamorelin?

CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH). Ipamorelin is a growth-hormone secretagogue (a GHRP). Both are studied for their action on the growth-hormone axis and are sold for laboratory and research use only.

CJC-1295 and ipamorelin are two growth-hormone research peptides that act on the same axis through different mechanisms. Because their actions are complementary, they are among the most commonly paired compounds in growth-hormone secretagogue research, and are often sold as a single combined blend.

What are CJC-1295 and ipamorelin?

CJC-1295 - a synthetic analog of growth-hormone-releasing hormone (GHRH). It is studied for its action on the pathway that signals growth-hormone release.
Ipamorelin - a growth-hormone secretagogue (a GHRP, or growth-hormone-releasing peptide) that acts on the ghrelin receptor. It is noted in research for being relatively selective.

Why they are studied together

The two compounds engage the growth-hormone axis by separate routes - CJC-1295 as a GHRH analog and ipamorelin as a secretagogue. Research frequently pairs them to study the combined effect, which is why they are commonly offered together as a CJC w/ Ipa blend. We also carry each on its own for protocols that call for a single compound.

CJC-1295: with DAC vs. no DAC

CJC-1295 comes in two research forms:

No DAC (sometimes called mod GRF 1-29) - a shorter-acting form.
With DAC (Drug Affinity Complex) - a modification that extends the compound's half-life so it circulates longer.

Both are research materials; the choice depends on the study design. Browse the options in the research peptide catalog.

Forms & handling in the lab

These peptides ship as lyophilized (freeze-dried) powder, commonly in 10 mg research vials and as the combined blend. Before use they are reconstituted with bacteriostatic water; the water volume you add sets the concentration in mg/mL.

🧮

Calculate concentration & syringe units

Enter vial size, water volume, and target amount for exact figures.

Storage & stability

Lyophilized powder - most stable form; keep frozen or refrigerated and protected from light until reconstituted.
Reconstituted solution - refrigerate at roughly 2-8 °C; as a general research guideline, use within about 28 days.
Avoid repeated freeze-thaw cycles, heat, and shaking, which can degrade the peptides.

Frequently asked questions

What are CJC-1295 and ipamorelin?

CJC-1295 is a GHRH analog and ipamorelin is a growth-hormone secretagogue. Both act on the growth-hormone axis and are sold for laboratory and research use only.

Why are they combined?

They work through complementary mechanisms on the same axis, so research often pairs them, and they are commonly sold as a single CJC w/ Ipa blend.

What does DAC mean?

Drug Affinity Complex, a modification that lengthens the half-life. CJC-1295 no DAC is shorter-acting; the DAC version circulates longer.

How are they reconstituted?

With bacteriostatic water; the water volume sets the mg/mL concentration. Our calculator and reconstitution guide cover the math.
