CJC-1295 in Steinberg — GHRH Analog Research Guide
CJC-1295 research guide for Steinberg. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Steinberg looking to source CJC-1295, the key fact to understand is that this compound is available only through an online research supply market. The practical takeaway for Steinberg researchers: sourcing CJC-1295 depends entirely on vendor quality evaluation, not geography — and the framework for evaluating that quality is universal across all locations. What consistently distinguishes top CJC-1295 vendors is complete batch-specific analytical documentation: HPLC for purity, mass spec for molecular identity verification, and endotoxin testing for contamination assurance. What follows is a vendor evaluation and quality guide built specifically around CJC-1295, covering everything a Steinberg researcher needs to evaluate quality systematically.
Understanding CJC-1295 — Biology & Evidence
CJC-1295 with DAC (Drug Affinity Complex) is a GHRH analogue with an extended half-life achieved through DAC technology that enables covalent binding to albumin. This modification extends the half-life from minutes (for native GHRH) to approximately 6-8 days, creating a sustained elevation in basal GH levels rather than the pulsatile pattern produced by GHRP compounds. This pharmacokinetic distinction is significant for research design: CJC-1295 based on CJC-1295 with DAC produces a different GH secretion pattern than GHRP compounds, with different downstream effects on IGF-1 and protein synthesis. Researchers in Steinberg comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
Sourcing Research-Grade CJC-1295
Before assessing any particular supplier, understand what genuine quality documentation contains — so you can tell whether a COA is complete and credible. Mass spectrometry in the COA establishes that the main HPLC peak is actually CJC-1295 and not a structurally similar impurity — HPLC purity alone provides no identity confirmation. For Steinberg researchers evaluating vendors with limited track records: a modest first purchase to test the product before committing to research quantities is standard practice in the community. For Steinberg researchers making a first CJC-1295 purchase: verify the vendor against this framework, begin with a small order, and confirm the COA batch number matches your received product before use.

CJC-1295 operates outside the framework of pharmaceutical oversight — researchers should understand that the known safety profile is based on preclinical evidence rather than regulated clinical data. Reconstitute CJC-1295 with bacteriostatic water at the concentration suited to your research design; a standard 5mg in 2mL gives a 2.5mg/mL solution — or 25mcg per insulin syringe unit. Bacterial endotoxin contamination is the most serious safety risk unique to this class of compound — verify endotoxin testing is documented in your batch COA before any injectable research application. Protocol documentation — keeping clear records of compound, timing, and method — is a fundamental research principle that allows any unexpected observations to be properly contextualised.
Frequently Asked Questions
What is CJC-1295?
CJC-1295 is a synthetic GHRH (Growth Hormone Releasing Hormone) analogue. The version with DAC (Drug Affinity Complex) has an extended half-life of approximately 6-8 days due to albumin binding. Without DAC, CJC-1295 has a much shorter half-life similar to native GHRH. Both versions stimulate pulsatile GH release via the GHRH receptor.
What is the difference between CJC-1295 with DAC and without DAC?
CJC-1295 with DAC uses a lysine-maleimide conjugate to bind covalently to albumin in the bloodstream, extending half-life to ~6-8 days and creating sustained GH elevation. CJC-1295 without DAC (also called Mod GRF 1-29) has a half-life of ~30 minutes and produces acute GH pulses. They produce different GH secretion patterns and have different applications in research.
What purity is required for CJC-1295 research?
CJC-1295 should be ≥98% pure by HPLC. The larger molecular weight of CJC-1295 with DAC (approximately 3647 Da) makes mass spectrometry confirmation particularly important, as impurities may not be obvious on HPLC alone.
