Modified GRF (1-29) / GHRP-2 Blend is a lyophilized peptide blend supplied exclusively for controlled laboratory research. Modified GRF (1-29) is a synthetic analog used in research involving growth hormone-releasing hormone receptor-associated pathways. GHRP-2 is a synthetic peptide used in research involving growth hormone secretagogue receptor-associated pathways. The combined material may be evaluated in controlled in vitro or analytical studies examining receptor-associated signaling, assay behavior, and interactions between two defined research compounds.

THIS PRODUCT IS NOT INTENDED TO TREAT, CURE OR DIAGNOSE ANY CONDITION OR DISEASE AND IS NOT FOR HUMAN CONSUMPTION. ALL PRODUCTS OFFERED ARE INTENDED FOR LABORATORY RESEARCH USE ONLY.
All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

The product is supplied in lyophilized form. Store the sealed vial in a cool, dry environment protected from heat, light, and moisture. Laboratories should follow the storage conditions shown on the product label and applicable lot-specific documentation.
For longer-term storage, use validated laboratory storage controls appropriate for the material and maintain a documented temperature history in accordance with institutional standard operating procedures. Avoid repeated temperature changes and conditions that may compromise container integrity.
These storage statements apply only to the sealed research material as supplied. Preparation and application instructions are not provided.

Use the Certificate of Analysis associated with the applicable lot to review reported identity, purity, and analytical testing information. COA documentation is provided for laboratory quality-control and recordkeeping purposes and does not establish suitability for human, animal, clinical, diagnostic, or therapeutic use.
The Modified GRF (1-29), GHRP-2 Blend is supplied as a laboratory research material. Product amount and lot details should be confirmed on the vial label and corresponding COA.
The Modified GRF (1-29), GHRP-2 Blend contains two synthetic peptides in a lyophilized research format. It is intended for controlled laboratory work involving compound identity, analytical characterization, receptor-associated pathway models, and comparison of blended and single-component assay conditions.
Because a peptide blend contains more than one research compound, laboratory protocols should document the product lot, assay conditions, controls, sampling intervals, and analytical methods used. Results should be interpreted only within the limits of the validated experimental system.

Modified GRF (1-29) is a synthetic peptide analog used in laboratory research involving growth hormone-releasing hormone receptor-associated signaling. GHRP-2 is a synthetic peptide used in research involving growth hormone secretagogue receptor-associated signaling.
In a controlled research setting, the blend provides two defined compounds in one material for analytical or in vitro study. Researchers may use appropriate controls to compare the blend with its individual constituents, characterize assay responses, or examine receptor-associated signaling variables. This description identifies established areas of laboratory research and does not claim a physiological, clinical, or therapeutic outcome.
Researchers studying the individual compounds can also reference the product pages for CJC-1295 (without DAC) , which is commonly associated with Modified GRF (1-29) nomenclature in research catalogs, and GHRP-2.

The blend may be used in validated laboratory models designed to examine variables associated with growth hormone-axis signaling. Experimental conclusions should remain limited to the assay, model, controls, and analytical methods used.
Laboratory studies may use the material to investigate GHRH receptor-associated and GHS-R-associated signaling within defined endocrine pathway models. This research context does not imply a clinical application or health outcome.
Researchers may measure predefined analytical markers in controlled experimental systems to characterize assay responses associated with the two constituent peptides. Appropriate negative, positive, and single-component controls should be included where relevant.
The blend may be compared with individual constituent materials under standardized laboratory conditions. Comparative studies should document material identity, lot numbers, assay parameters, controls, and analytical endpoints for reproducibility.
