About CJC-1295
What is CJC-1295?
Overview
What is CJC-1295?
CJC-1295 is a synthetic analogue of growth-hormone-releasing hormone based on the GHRH(1-29) fragment, carrying four amino acid substitutions that increase resistance to enzymatic degradation. We stock three forms: without DAC (also sold as Modified GRF 1-29), with DAC (a drug affinity complex that extends half-life via albumin binding), and a CJC-1295 with Ipamorelin blend.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should CJC-1295 be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is CJC-1295 researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what CJC-1295 does, and nothing here is a statement that it is safe or effective for any purpose.
Growth hormone release
CJC-1295 mimics GHRH, the hypothalamic signal that tells the pituitary to release growth hormone. Native GHRH is destroyed within minutes; four amino acid substitutions let this analogue survive long enough to study. 1
DAC versus non-DAC half-life
The DAC version binds covalently to albumin in blood, extending its presence from hours to days. Comparing the two forms is one of the cleanest available ways to study how half-life alone changes a hormonal signalling pattern. 1
Combination with ghrelin agonists
GHRH analogues and ghrelin receptor agonists such as Ipamorelin act through separate receptors. Research frequently pairs them to examine whether the combined signal exceeds either alone, which is why the blended vial exists.

Batch COA
Verification
Does CJC-1295 come with a COA?
Yes — every box. Each batch of CJC-1295 is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
CJC-1295 questions, answered
What is the difference between CJC-1295 with and without DAC?
DAC stands for Drug Affinity Complex, a maleimidoproprionic acid group that binds covalently to serum albumin and substantially extends the circulating half-life. Without DAC (Modified GRF 1-29) the molecule is around 3368 g/mol and short-acting; with DAC it is around 3647 g/mol and long-acting. They are distinct compounds and are priced separately below.
How much does CJC-1295 cost?
CJC-1295 starts at $10.07 per vial, sold in boxes of 10 vials at $100.71 per box (about £75.45). 5 strengths available: 5 mg (no DAC), 10 mg (no DAC), 2 mg (with DAC), 5 mg (with DAC), 10 mg (with DAC). There is no minimum order.
How is CJC-1295 shipped to the UK and USA?
