Lyophilized form helps protect peptide quality. Peptides are supplied as a dry powder, which may look like a compact "puck" or a lighter powder inside the vial.
Because the peptide is dry, it does not require refrigerated shipping during normal transit, including warm seasonal conditions. For longer storage, follow the storage guidance in the product description.
Appearance can vary. The stated peptide content is checked through third-party analysis.

Solution not bundled
Peptides are delivered as lyophilized powder. This dry form helps preserve peptide quality during storage and transport and does not require refrigerated shipping during normal transit.
To prepare a solution, use a solvent such as Bacteriostatic water. It is sold separately, so add it only when you need it for peptide preparation.

DAC-linked GHRH analogue for albumin-binding and extended-exposure pathway studies.

Research overview
CJC-1295 with DAC
The DAC modification makes this analogue different from modified GRF(1-29) without DAC. This difference matters when comparing binding, duration, and receptor-signalling studies.
Studies measure growth-hormone release, growth-related markers, and reproductive-system signals. These are study findings, not claims about the supplied material.
Albumin binding and signalling duration
The DAC group is designed to bind albumin and extend circulation in laboratory models. Researchers compare how this changes exposure and endocrine measurements versus a no-DAC analogue.
Each comparison should use the exact sequence, assay, and observation time reported in the paper.
Endocrine model endpoints
Published studies also measure growth-hormone and IGF-related endpoints. These measurements do not define the quality or behaviour of a supplied lot.
Soluble in bacteriostatic water and suitable aqueous laboratory solvents.
Product note
Albumin-binding GHRH analogue research compound; supplied strictly for research use only.
Laboratory care
Handling
Peptides in transport
Peptides in lyophilized form are supplied in glass vials by standard shipping methods and do not require refrigeration. Short-term temperature fluctuations during transport will not reduce their quality and efficacy. Even at high summer temperatures, the peptides in lyophilized form are stable for several weeks.
Storage of lyophilized peptides
Lyophilized peptides should be stored in a dry place, protected from light and moisture. The following storage conditions are generally recommended:
Room temperature (15–25 °C): Up to 3 months
Refrigerated (2–8 °C): Up to 6 months
Frozen (-20 °C or below): 3–5 years (recommended for long-term storage)
Allow the vial to reach room temperature after taking it out of the refrigerator or freezer.
Storage of reconstituted peptides
Once reconstituted, peptide solutions are generally less stable than their lyophilized form and should be stored under refrigerated conditions whenever possible.
The following storage conditions are generally recommended:
Room temperature (15–25 °C): Avoid prolonged storage
Refrigerated (2–8 °C): Typically 4–8 weeks
Frozen (-20 °C or below): Up to 3–4 months
To preserve peptide integrity, avoid repeated freeze–thaw cycles, as these may accelerate peptide degradation.
Important: Most manufacturers recommend discarding reconstituted peptides within 4 weeks when stored at 2–8 °C. This recommendation is intentionally conservative and may not reflect the actual chemical stability of every peptide. In our own stability studies, many peptides reconstituted in bacteriostatic water showed no detectable degradation after 12 weeks of refrigerated storage. As peptide stability is highly sequence- and formulation-dependent, this result should not be extrapolated to all peptides without supporting stability data.
