What is — CJC-1295 (MOD-GRF)
CJC-1295 (MOD-GRF), also written as CJC-1295 without DAC or MOD-GRF (1-29), is a synthetic modified analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH). It is supplied as a lyophilized (freeze-dried) 5 mg powder in a sealed vial for laboratory research. Peptworks provides it as a research reagent for Research Use Only (RUO): it is not for human or animal consumption and is not a medicine, supplement, cosmetic or medical device. Each batch is characterized by independent analysis (≥98% HPLC purity, heavy metals) with a per-batch Certificate of Analysis accessible via a unique QR on the box.
In preclinical and in-vitro research models, CJC-1295 (MOD-GRF 1-29) acts as a GHRH-receptor agonist. It is a truncated GHRH(1-29) sequence carrying amino-acid substitutions intended to improve resistance to enzymatic degradation relative to native GRF(1-29). Unlike the DAC-modified variant, the MOD-GRF (1-29) form does not include the Drug Affinity Complex moiety, so research literature generally describes it as a comparatively short-acting GHRH analog. Investigative work typically examines its interaction with somatotroph GHRH receptors and downstream signaling associated with pulsatile growth hormone release in cell and animal systems.
Research
- GHRH-receptor signaling and somatotroph biology in vitro
- Comparative pharmacokinetics of DAC vs non-DAC GHRH analogs in animal models
- Growth hormone / IGF-1 axis regulation studies in preclinical systems
- Peptide stability, formulation and lyophilization research
- Analytical method development (HPLC identity and purity assays)
- Receptor-binding and structure-activity relationship studies
Advantages
- Used as a reference GHRH-analog agonist in receptor and signaling assays
- Serves as a comparator for studying DAC vs non-DAC analog kinetics in animal models
- Supports investigation of the GH/IGF-1 regulatory axis in preclinical research
- High-purity (≥98% HPLC) lyophilized format suitable for reconstitution in laboratory protocols
- Per-batch CoA supports experimental reproducibility and analytical traceability
Safety
- Not applicable to humans or animals as a product; the following are observations reported in the research literature and in-vitro/animal models only
- Reports in animal models of transient injection-site reactions in dosing studies
- Research literature notes possible effects on glucose and IGF-1 parameters in animal models
- Peptide sensitivity to temperature and moisture can affect stability if not stored correctly
- As a laboratory reagent it has no established human safety profile and must not be administered to people
Ideal for
- Academic and contract research laboratories running GHRH-pathway assays
- Analytical labs developing or validating HPLC identity/purity methods
- Formulation and peptide-stability research programs
- B2B resellers and distributors sourcing bulk or white-label research peptides in the EU
- Research organizations needing per-batch CoA traceability for reproducible studies
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy CJC-1295 (MOD-GRF) in bulk in the EU?
Peptworks is a B2B wholesale and white-label supplier with CJC-1295 (MOD-GRF) 5 mg lyophilized vials held in stock inside the EU. Orders ship intra-community in 3-5 business days with no customs. Orders start from a 4-vial pack per reference. Supplied strictly for research use only (RUO); Peptworks does not sell to end users.
What is the wholesale CJC-1295 (MOD-GRF) price per vial?
CJC-1295 (MOD-GRF) 5mg has two public per-vial prices: €39.90 in a 4-vial pack and €25.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs. Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. no card on site.
Do you offer CJC-1295 (MOD-GRF) as white-label?
Yes, in the white-label sense: CJC-1295 (MOD-GRF) comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for CJC-1295 (MOD-GRF)?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the CJC-1295 (MOD-GRF) Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (≥98%) and heavy metals. The outer box carries a unique QR code that links to that specific batch's CoA, verifiable through Peptworks, so your customers can confirm identity and purity per batch.
How fast is EU delivery and is it Research Use Only?
Because stock is already inside the EU, orders ship intra-community in 3-5 business days with no customs clearance. All material is a laboratory research reagent supplied for Research Use Only (RUO): not for human or animal consumption, and not a medicine, supplement, cosmetic or medical device.
