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.

GHRH analogue
CJC - 1295 (no-DAC)
In stock
CJC-1295 no DAC, also called modified GRF(1-29), is a synthetic GHRH analogue without a drug-affinity complex. Published studies look at analogue design, VIP-receptor interaction, and growth-hormone-response measurements.

Research overview
CJC - 1295 (no-DAC)
The no-DAC form is different from albumin-binding CJC-1295. Its modified GRF(1-29) sequence should be considered separately in receptor studies and analytical records.
Studies cover gastrointestinal receptors, metabolic models, and endocrine responses. These reports provide research context, not a promised product outcome.
Analogue design and receptor selectivity
Studies show how shortened GRF analogues and small amino-acid changes can affect clearance and receptor interaction. Other experiments measure VIP-receptor binding and adenylate-cyclase activity.
These comparisons show why small sequence changes can produce different laboratory readings.
Endocrine-response studies
Published work also measures growth-hormone responses in metabolic and thyroid-related models. The results belong to those study conditions, not to an individual product lot.
Soluble in bacteriostatic water and suitable aqueous laboratory solvents.
Product note
Modified GRF(1-29) / CJC-1295 without DAC; 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.
