Structural Composition
Ipamorelin (5-amino-acid synthetic growth hormone–releasing peptide) + CJC-1295 No DAC (modified 29-amino-acid growth hormone–releasing factor analog)
Physical Properties
This blend combines Ipamorelin, a short synthetic pentapeptide containing non-natural amino acid residues, with CJC-1295 No DAC, a modified 29-amino-acid growth hormone–releasing factor analog featuring targeted amino acid substitutions for enhanced stability. Because the formulation contains two structurally distinct peptides of different molecular sizes, overall molecular formula and molecular weight are inherently variable and depend on blend ratios and hydration state. Lyophilized presentation supports storage stability, while protection from moisture, light, and repeated freeze–thaw cycles helps maintain structural integrity and analytical consistency for laboratory and research applications.

Laboratory Handling and Storage Protocols
Lyophilized Powder Storage
- Store at –20°C to –80°C in the original, sealed vial
- Protect from light exposure and moisture
- A desiccated storage environment is recommended
- Stability data suggests extended stability when stored at −20 °C or below.
Reconstituted Solution Storage
- Short-term storage: Up to 7 days at 4°C
- Long-term storage: Store at –20°C in aliquots
- Use single-use aliquots to preserve peptide integrity
- Minimize freeze–thaw cycles; single-use aliquots are strongly recommended
Stability Characteristics
Ipamorelin + CJC-1295 (No DAC) Blend is a synthetic multi-component peptide research formulation composed of short-acting growth hormone–related peptides. As a composite preparation, stability depends on proper cold storage of the lyophilized material, careful reconstitution, and minimized freeze–thaw exposure. When handled according to standard peptide laboratory protocols, the blend maintains structural integrity and solubility suitable for in vitro and analytical research applications.
Frequently Asked Questions
What is the Ipamorelin + CJC-1295 (No DAC) blend?
This is a research formulation combining:
-
Ipamorelin — a selective growth hormone secretagogue acting on the GHS-R1a receptor
-
CJC-1295 (No DAC) — a modified GHRH analog targeting the GHRH receptor without the extended half-life DAC modification
The blend enables investigation of dual-pathway activation in experimental models.
What does “No DAC” mean?
“No DAC” indicates that the CJC-1295 component does not include the Drug Affinity Complex modification. As a result, it demonstrates a shorter duration of activity in research models compared to CJC-1295 with DAC.
Why combine Ipamorelin and CJC-1295 (No DAC)?
Researchers may combine these peptides to evaluate:
-
Complementary receptor activation
-
Coordinated endocrine signaling mechanisms
-
Experimental models requiring shorter activity windows
-
Comparative results versus DAC-modified variants
This approach may allow greater control over timing variables in certain research designs.
Is this a single peptide?
No. This is a multi-peptide blend, not a single amino acid sequence. Each component retains its distinct structural and receptor-binding characteristics within the formulation.
How is the blend supplied?
The blend is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials to maintain stability during storage and shipment.
How should unreconstituted blend vials be stored?
Lyophilized blend vials should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted blend solutions be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does this blend require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying identity and purity for both peptide components within the blend to ensure research quality and traceability.
